I wish I could meet you in person and have you literally trained me videos are great but hands-on experience is the best way of learning especially when you have someone like you next to you to explain everything on the Fly and I love that you say this potential energy scares you listen up people that this energy scares him it should terrify you be very careful.
My grandson just told me that he wants to be exactly like you. Because he said that you are a genius in electricity and alternative energy systems. He's only six years old?
The smaller units have a shorter warranty - it looks like you can spend another $300 and get one with low temp cut-off. Crazy good deal, good find. Thanks for the review.
$3870 for 10kwh is a good deal. It compares to a $500 1280 wh battery. Additional savings comes from the reduced wiring requirements plus having a battery monitor build in. I guess they are finally taking on the diy firewall market. My planned system is - 8 kw Solar - 32 kw 48v battery Just 3 of these batteries would do the trick. I won’t be ready for another 2 years, it’s safe to assume the competition will increase and the price will drop. Exciting times.!
SOOO glad to see you testing these. We purchased one back in July/2020 and think its a BEAST. We went with a 48V 10Kwh unit. EDIT: So we just noticed our battery is not even remotely reaching the state of charge you show in your video. (our ceiling appears to be 53.98V) Should we be concerned? We're also in a much colder climate in Idaho! However, the battery lives in a heated workshop at about 58 degrees.
There are several different packs and some of them have different cell count so voltage will be differenent. I got the 13.4kWh pack with 15 cells so the voltage is different than 16 cells
@@raselharfe9018 We utilize an Outback Radian GS8048A-01 8,000 Watt Advanced Inverter/Charger which was and is part of a FLEXpower Radian Powerwall prewired setup. As to watts and how long that lasts, that is going to vary highly dependant on use. Your mileage can and will vary.
been watching all your videos for years here in the philippines.. no bias but 100% honest review for the viewers to know and to learn.... hope to see more new products on your review that has good quality still even its cheaper than other brands..... i hate those expensive brands as all hahaha
Thanks for the review, I've been thinking of upgrading my system to two of the 7.5Kwh packs. Based on what you've shown us here it helps a lot to feel comfortable in making that change.
At 200+ pounds, the fact that you can move the LiFePO4 proves that you are a strong Will. The brain power is further indication of a strong Will. You are helping many.
thanks to your channel I'll be DIY building a 48v LIFEPO4 10kwh battery tomorrow. I have all the parts and I'm ready to start. Mine cost 0.27c (aud) per wh
I have a solar company in Missouri and we put these in more often than anything else. I built a cable hoist to lift them in a controlled way. My only complaint is that the bms is not compatible with the Sol-Ark.
BMS looks like a seplos. I tried to post a link but think was filtered. A 200amp seplos cost me $250 shipped to my front door. I bought specifically for communication ports so it would communicate with my inverter
Great video. Two QUESTIONS 1. Would it be a lot easier and cheaper to have a single 10k unit or a lot more complex and $ to hook up two 5 k units... 2. and would two 5 k units. really provide equal power or less than one 10 k?
@Andrew Mo ... Looks like the company "may have" already gone bust, as I can't get to the site using "any" of the battery/product links Will provided. I even tried dropping the product number and it's still a "no go." To bad...
It's a really good time to be getting into solar and thinking about power walls. I just had a 9kwh system go on the roof with go-live in about 2 weeks, but it's strictly a grid-tie system with no off-grid support (batteries). My SO remembered Tesla Powerwall and got all excited but I told them no on Tesla due to all the problems and high cost. Trying to steer towards an EV battery for price and safety, but seeing products like this starting to splash down is exciting.
Riddle me this Will (please). My first started on your channel it was to add a solar system to my RV. Back when 20, 50 80 watt panels were popular. Anyways you had just come out with your book and I bought a hard copy. So I've been watching you since then. With knowledge obtained from all your videos I've installed solar system on the last three RVs I've owned. The very last one I use those little 50 amp reclaim batteries from the hospitals crash carts. I picked up six of them for ridiculously low price. It worked awesome we never were concerned about running out of house battery power. Anyways I sold that unit about another one, it came with one 12 volt battery that I upgraded to two golf cart batteries. There's a lot of things needed to be upgraded or fixed/repaired on this RV so inexpensive golf cart batteries was the way I had to go at the time. What is the most cost efficient lithium style battery that you would recommend for an RV? Thank you very much congratulations on your success and your improvement in health
Nick..I did not have much luck with my local hospital when I tried to put my hands on those batteries. How did you go about getting those that you used?
between your channel and other more simpler explanations on solar setups, I really want to get started and make a percentage of my house off grid at least. Very informative. Thanks
Another great video Will! Did you notice that the 5 kWh and 7.5 kWh units have a 6000 charge cycle life with a 10 yr warranty where the 10 kWh unit has a 20 yr warranty but only a 4000 charge cycle life? That’s less than 11 yrs of daily cycles.
BYD just recently announced that they now can produce their BLADE batteries for less than 100$/kWh on the pack level. These batteries are rated for up to 10.000 cycles. That’s for the automotive industry, batteries for home storage usually are a good bit more expensive, at least for now and of course it’s not the price for the consumer. But I expect the prices to drop by about 50% over the next 12 months. At that price point you are down to 2-3 cents per cycle/ per kWh. That makes these batteries interesting not only for people who have solar, but also if you just have hourly tariffs or want to cut down your peak demand. Once people have the batteries, of course they will want to have solar as well.
The BYD Blade batteries are an exciting technology. I hope the car that they're being shown in, the Dolphin, makes it to the US market someday. Googling "BYD Blade batteries for sale" brought up a listing on a Chinese retail site for me. I'd be interested in seeing who goes first in sourcing them for a DIY solar project, or even a DIY EV project.
Yes, as soon as they put a dyson sphere around the sun. TBA next year. Stay tuned to this channel folks, this is history(onoics) in the making. ....Sometimes companies make these claims to throw off the competition, by making them spin their wheels in unproductive side ventures.
Great video. I just subscribed. It's funny hearing you complain about how much that battery weighs. We installed our off grid system almost 6 years ago and went with flooded lead acid batteries. Our battery "system" weighs about 7500 pounds - so yeah that's heavy. I'm certain when we are forced to change out our batteries in the future, we can convert to a much lighter technology. I hope that's at least another 10 years out. We try to never drop under 75% SOC.
As I watch you struggle with that Anderson connector it reminded me of the one I use on our aircraft. A 175 amp Anderson with a little bit of dielectric grease on it changes the whole dynamic.
Im becoming a fan of the rack systems for batteries. Seems like this would work well in one if the screen was on the bottom. 2 people could then lift it and slide it right in. Still anything over 200 pounds is going to be cumbersome. Great video
Just an FYI, the company that makes these batteries is called Liniotech and are based out of Houston, Tx. The person you'll end up talking to is Chris Wang. He knows his stuff and will help you out tremendously.
Checked the page. Is this true? "When the temperature sensor detects a cold outside temperature, it will warm up the cells first before it allows the cells to be charged. Without the sensor, the cells cannot be charged under 23F (-5C) and discharged under -22F (-30C)."
I am confused by that too. Mine has the sensors, but they were glued and possibly screwed to the bus bars, so I couldn't test them. I tried to, but I did not want to screw it up. Good point, I need to ask them about that.
@@WillProwse good point I live in the Panama City area of Florida were occasionally temperature drops below freezing. Is this a safe Marine application on a sailboat where there is vibration on the sailboat when the diesel engine is running. Second thought would this be a fire-safe unit similar to battleborn?
One thing I see that concerns me is how the negative group of cables is laying over the positive pcb. When going back to 2:20 I do not understand why there is the big loop in the negative carriers when they could have easily been routed straight into the battery area without looping over the positive side of the pcb. Strange. Even with the white plastic wire looms over that bundle of negative carriers, I am not comfortable. I have been a bench level tech and lo and hi V installer for many decades. Even in fixed applications, I try to avoid any near or cross placements of different polarity carriers. While I recognize that space is at a premium in this battery system, it only takes a few seconds for high amperage dc power systems to go very quickly into a disastrous situation.
Great content as always! Please if you feel inclined, make an in depth video for us newbies on how to prepare recycled prismatic cells for a battery pack. I love to rescue, and it seems that the scrapyards really want to pawn off LiFePo4 cells to whomever they can. Roughly $2 Australian per kWh which still makes sense to me, even at a severely reduced capacity. All the best :)
Damn Will, that is one of the sexiest batteries I've seen you test. I love the fact you can see how many cycles you go through.. the menu is simple and informative. I mean damn. Itll be in my dreams. Well done and thank you for the excellent review. Particularly for lifting the skirt to see the cells 😋😛
Too bad they don't let you reverse the display text to work upside down.. or simply do a 180 degree flip on the physical display, and leave extra holes for buttons in both orientations. I would put hot melt glue down the back of the DC connector, so nothing could short it out that way...
The 13.4 kwh battery looks like different technology it goes together in multiple pieces or module packs. Its internals appear to be completely different. Also with a 20year warranty vs 10 year
6kw max charge rate? you may look into old used cisco catalyst ws-cac-6000w power supplies they can do 6kw at 42v, but you can increase with a internal potentiometer to 48v or slightly higher (depends on what caps are installed 50 or 63v) these supplies go for real cheap on ebay, i got one for under 30 bucks but i think the 6kw is only for 240v circuits, 110v people gotta stick with 3kw. its not constant current, needs extra stuff for charging batteries directly.
Not sure if I missed it in the video or not, but did this battery have a Low Temp protection ??? I need a system for an off grid cabin in Northern Michigan
RVs wanting a heat pump: I saw a 12v DC mini split on Alibaba. It even connects directly to solar panels and a battery, or it can do 120v when DC is low if 'the sun don't shine'. 12v DC would be great if you already had a 12v system.
What enphase do right is making them modular. That eliminate the need to move something so heavy. Further, it is expandable and component replaceable. What really needs to happen is to make all in one unit easy for consumer to use, install and maintain. It needs to be modular, otherwise too heavy. Your videos are great.
In the Denver metro area you can go to grid Alternatives and you can buy used or slightly scuffed panels every one of these modules is of the newer class 315 w so something to look into they only charge $20 per module
Hi Will, I think your tube channel is brilliant. As a Brit thinking of attempting to go off grid, I would love to know if the battery units on your channel are available in Britain.
The only issue with US units is in the inverters as they all output 110v instead 220 (there are some that do 110/220), but be aware… regarding batteries and battery packs, you’re safe to use anywhere in the world
Besides being more expensive, how does this compare to the EG4 over at SignatureSolar? The 5KWh of this costs $2347. The 5.12KWh EG4 "pro" costs $1749. Another great video. Thanks Will
@@patrickburton6130 That must have been a sale because I cannot find any of their large packs that cheap. Check out this one. shipping is $900: www.aliexpress.com/item/1005003127749308.html?spm=a2g0o.search0304.0.0.1abba57dt7dM0V&algo_pvid=ef482035-838d-4339-a17a-20283f76e63a&algo_exp_id=ef482035-838d-4339-a17a-20283f76e63a-8
Being that those are relatively small cells, as in a very shallow design, that may facilitate the horizontal orientation. Bigger cells may be more susceptible to orientation issues.
I feel like i am a Bank Robber & i just open the VAULT!!!! lolololol. Love this guy. Never a boring moment. Very good Information for us all. Keep up the great videos & Testing.
Will. To set things up, I worked in San Antonio, Texas years ago where I worked in shipping containers that had been converted into storage. The temperature inside of those things would reach 120 to 130 degrees F even in the insulated containers. There were even a few times that they approached 140 degrees F. All of those containers were water tight and little air circulated through them. The containers that I worked in had open doors. God only knows what the temperatures would be with the containers closed for several days or weeks. Listening to you and others that review DIY prismatic cells two common threads are that the ones from China are weeks and months in shipping and quite often the cells that you all recieved were puffed up. More than likely, they were shipped in containers like I described. I have two questions in relation to this information. First, knowing that heat is bad for Li batteries, would the heat that I have described be harmful to cells that are in transit for weeks and months? Second, would a person be better off paying shipping fees for faster transit so that the cells that arrive have not been cooked for days and weeks on end? I know that grade B cells are often pawned off in other countrys by Chinese firms, but how long could they really get away with that practice before word spread and they couldn't sell in the US or Europe? For those reasons, i belive that at least some of the problems that we see with battery cells out of China are the result of poor shipping practices. 'What do you think? Thank you
@@WillProwse Hurry Will. We are at the stage now of All-in-One Inverters + Battery(ies) or the new AC300 with B300 & Fusion Box Pro. Plse. add a Pros & Cons to each route. We are also looking @ cost differences of going one way or the other! Remember, a lot of us are on a strict budget. We can't afford to do both. The anticipation is killing me!!!!!!
Just a quick question as I'm ignorant. You can parallel different types of lithium batteries together in one system like that safely? I'm only asking for my own experimentation. Thanks for all you do!
Thats still mighty pricey. I paid $1500 for 8kwh, but to be fair, i had to assemble it my self and it does t look as pretty. All parts considered, i still paid half of what they are charging. Assembly is simple - get batteries, assemble on a flat surface, with 90degree angle to butt it up against. Glue cells together temporarily with hot-glue. Order nickel strips, cut them as needed, build basic welder using a button, car starter relay $35@local parts store, and some thick copper wires mounted on a wooden block. Use car battery for the power source and get a solid fuse to prevent stupid mistakes. Get hole saw, cut holes in the right places on a couple 2x4. Cut 2x4 along cener through the holes to provide a top-bottom supper. Sandwich between two ply board cut to right size, leaving room at top to mount BMS and DC fuse. Connect wire, add a connector like the one seen in the video and bam. Ive made 17kwh of power my self. Couple to 6000w of solar panels and midnite 150 solar charge controller. Make a LVC using $12 programmable delay with thermistor connected to the normally closed side of the board relay, and a 12V 100A relay connected to the normally open side of the board’s relay. This provides a soft start/inrush prevention to keep from damaging the inverter, and prevents the relay contacts from welding together, so the charge controller can shut off reliable when the voltage gets too low. I run two AC units, one that draws 1.4kw and one that uses 1.1kw. The second AC unit only comes on when it gets really hot otherwise its not needed. When the sun goes down i normally have 15-16kwh of power to: charge my neighbors car with the excess, run my two computers and do a number of things. The BMS has thermal cut off, but because the system is capable of taking in 3.4kw of charge at 1C, and charging never exceeds 4.8kw, the batteries NEVER heat up beyond 31C, in the summer, under full charge load. These batteries wont heat up appreciable until they reach 1.5-2C charge rate, which my system never achieves. If you are a DIYer, dont waste your money. Takes a few days to put the batteries together, a few days to charge and test. Batteries come charged at 3.2V per cell. Charge pack until any of the 16 rows of cells reach 3.45V, then using Variable DC power supply ( $50 amazon), charge each row to 3.65V and wait till final charge rate settles to .07A, perform this once more for each row 12hr later, then bolt the shell together. Bam. They are ready. BMS will balance them from here. Its been a year since my last balance and the batteries still dont need maintenance. If you have time and have the skills, dont waste your money on something like this
Looks like they changed the design for the 48v 13.5k. The packs in the pictures on the website show the pack up right in the case like you said is the normal position.
Thanks for the illustration on why you wouldn't want batteries lying down. For the build I've been thinking about, that's how I wanted to lay them (flat, side by side) as I wanted something as short as possible. I will have to think on this more.
How do you parallel the different batteries without huge power going through it to level the voltages? I assume lots of amps would flow because of the difference in voltages. Or you exactly matched them before?
@@michaels3003 Nurses discovered why they had back problems coming up to retirement: when they are young and lift patients, they get micro tears in the thin sheets between vertebra. When they retire, they have back problems. It doesn't show up for decades.
I just bought a 10kWh 48v BYD LiFePO4 200ah battery from Watts 247. It was $1500 cheaper than this one. I was hoping that you had a review for it, but I don’t see one. You should check out their 200ah battery and test it for us
I have a small solar farm limited to 74KW output to the grid. The only way for me to increase the energy production is to keep sending energy to the grid (@75kw) 24x7. Would it be feasible in 2022 have an 1.5MWh battery that is reliable and long lasting (10+ years). Thanks for sharing this. Love your channel
One of the issues with these batteries is the low C rating requiring multiple units to run a larger system. Requires one unit to run a 3 kW Inverter. Requires minimum of two units to run a 6 kW Inverter. Requires minimum of three units to run a 12 or 15 kW Inverter. Paralleling requires an additional cable (not included).
Their site may state that but we have had zero issue running a single battery to power emergency items in a power outage. Its connected to a Outback Power 8048A
Another awesome review video Will. Thank you so much - you give us DIY'ers a lot of confidence to do this ourselves. You mention other similar units under the blankets that are nearly identical.....do you think the Energetech battery and UFO Battery are basically one and the same? Thanks again for all you do Will.
Do you know if they have a distributor in the UK? I love your passion and diligence. I have only ever looked at these for "someday in the future". However, after seeing what you have been doing. The future seems to be now!
Hi. I have a Meritsun power wall10kw, 200ah for more than a year. I run my house, the split unit every day(12000btu) it cycles every day of witch it has a 6000 cycle life. And I am very happy. Lucas
I love your videos... half the time I don't have a clue what you're talking about but you're like a car wreck and I'm a passing "rubbernecker"... I CAN'T "NOT" WATCH. Your sincerity and openness about everything is why I watch!, So, I learned the basics for a 12ft box van and an ac200p Bluetti... thanks! Aloha
This battery is branded with different names..most examples are wall mounted..it would make more sense to have the connections at the top for wall mounting.
Will the Manufacturers website shows a 10 year warranty not a 20 year and I see no low temp protection on any but this model. I see none on the 5000 or 7500
Yes, good idea to add a fuse in that cable if you just have lugs on one end. Does it have an internal fuse? Anyway, thanks for the review. I think I'd rather get two of the 100AH batteries, I don't have a pallet jack (but have a better hand truck than you!). :-)
Got a 5.3kwh battery setup from bigbattery this year. I decided I wanted to add another one for capacity recently and they dont even barely have any batteries anymore for this entire year. Wish I would have gone with a larger battery setup like this from the start.
I definitely want to try 2 of these batteries, the 13kw variety. They again seem high as the devil but such a nice design for storage. I have 48 280 cells setup for 840 ah using Daly Smart BMS units. Annoying that they do not talk together as one. Adding 2 of these or even 1 would complete my requirements for daily power. I also ordered one of your chargers from SS. The 48v 25a one. I can\t wait to test it out on this large bank.
Wonder if this type could work in a RV oriented flat on back on a solid floor? It appears the cells should have little movement and cell bussbars have between cell bends to allow some movement, probably for cell expansion.
Thank you for all videos! Have you done a new video like you talk about in this video? Where you have test this for couple of months.. /the boat owner 🙂

$3870 for 10kwh is a good deal. It compares to a $500 1280 wh battery. Additional savings comes from the reduced wiring requirements plus having a battery monitor build in.
I guess they are finally taking on the diy firewall market.
My planned system is
- 8 kw Solar
- 32 kw 48v battery
Just 3 of these batteries would do the trick. I won’t be ready for another 2 years, it’s safe to assume the competition will increase and the price will drop.
Exciting times.!
Battery price won't drop in the next 5 yrs, due to higher demand from EV cars.
They are now $4370 in February, 2022.
Price can be reduced if your order is from the supplier directly.
We used to have a saying: "just because it has a handle, doesn't make it portable". 226#
in our radio club we got a donation of and old hp portable scope 3x 2x1.75 feet must have been well over 100lb. dozens of tubes
Just because it has a handle doesn't mean that handle is meant for people.
Is that why really really fat people have love handles
SOOO glad to see you testing these. We purchased one back in July/2020 and think its a BEAST. We went with a 48V 10Kwh unit. EDIT: So we just noticed our battery is not even remotely reaching the state of charge you show in your video. (our ceiling appears to be 53.98V) Should we be concerned? We're also in a much colder climate in Idaho! However, the battery lives in a heated workshop at about 58 degrees.
There are several different packs and some of them have different cell count so voltage will be differenent. I got the 13.4kWh pack with 15 cells so the voltage is different than 16 cells
Hi, what is the size of your inverter, what you are using for(watt wise) and how long it last, thx
@@raselharfe9018 We utilize an Outback Radian GS8048A-01 8,000 Watt Advanced Inverter/Charger which was and is part of a FLEXpower Radian Powerwall prewired setup. As to watts and how long that lasts, that is going to vary highly dependant on use. Your mileage can and will vary.
I have been waiting for you to review this. Thank you 😊
been watching all your videos for years here in the philippines.. no bias but 100% honest review for the viewers to know and to learn.... hope to see more new products on your review that has good quality still even its cheaper than other brands..... i hate those expensive brands as all hahaha
Funny thing. I am hooked on your videos whenever they show up in my suggestions on YT I watch them. 👍
Thanks for the review, I've been thinking of upgrading my system to two of the 7.5Kwh packs. Based on what you've shown us here it helps a lot to feel comfortable in making that change.
At 200+ pounds, the fact that you can move the LiFePO4 proves that you are a strong Will. The brain power is further indication of a strong Will. You are helping many.
thanks to your channel I'll be DIY building a 48v LIFEPO4 10kwh battery tomorrow. I have all the parts and I'm ready to start. Mine cost 0.27c (aud) per wh
I have a solar company in Missouri and we put these in more often than anything else. I built a cable hoist to lift them in a controlled way. My only complaint is that the bms is not compatible with the Sol-Ark.
It should be compatible with sol ark :) unless there are changes fron the mother company going to solark
If you sell these... would you know if they are compatible with bus life?
BMS looks like a seplos.
I tried to post a link but think was filtered. A 200amp seplos cost me $250 shipped to my front door. I bought specifically for communication ports so it would communicate with my inverter
Great video. Two QUESTIONS 1. Would it be a lot easier and cheaper to have a single 10k unit or a lot more complex and $ to hook up two 5 k units... 2. and would two 5 k units. really provide equal power or less than one 10 k?
The 10kw/h 200ah one is the one to have. Best bang for the buck hands down
If the biggest complaint Will has is, that it is too heavy, sounds like a great battery to me.
must weigh as much as a steel box
@Andrew Mo ... Looks like the company "may have" already gone bust, as I can't get to the site using "any" of the battery/product links Will provided. I even tried dropping the product number and it's still a "no go." To bad...

It's a really good time to be getting into solar and thinking about power walls. I just had a 9kwh system go on the roof with go-live in about 2 weeks, but it's strictly a grid-tie system with no off-grid support (batteries). My SO remembered Tesla Powerwall and got all excited but I told them no on Tesla due to all the problems and high cost. Trying to steer towards an EV battery for price and safety, but seeing products like this starting to splash down is exciting.
Riddle me this Will (please). My first started on your channel it was to add a solar system to my RV. Back when 20, 50 80 watt panels were popular. Anyways you had just come out with your book and I bought a hard copy. So I've been watching you since then. With knowledge obtained from all your videos I've installed solar system on the last three RVs I've owned. The very last one I use those little 50 amp reclaim batteries from the hospitals crash carts. I picked up six of them for ridiculously low price. It worked awesome we never were concerned about running out of house battery power. Anyways I sold that unit about another one, it came with one 12 volt battery that I upgraded to two golf cart batteries. There's a lot of things needed to be upgraded or fixed/repaired on this RV so inexpensive golf cart batteries was the way I had to go at the time. What is the most cost efficient lithium style battery that you would recommend for an RV? Thank you very much congratulations on your success and your improvement in health
Nick..I did not have much luck with my local hospital when I tried to put my hands on those batteries. How did you go about getting those that you used?
between your channel and other more simpler explanations on solar setups, I really want to get started and make a percentage of my house off grid at least. Very informative. Thanks
Another great video Will! Did you notice that the 5 kWh and 7.5 kWh units have a 6000 charge cycle life with a 10 yr warranty where the 10 kWh unit has a 20 yr warranty but only a 4000 charge cycle life? That’s less than 11 yrs of daily cycles.
Yes and it's kind of confusing I'll say.
I guess they expect less cycling with a bigger capacity, because the battery won't be drained every day.
@@superdau makes sense
BYD just recently announced that they now can produce their BLADE batteries for less than 100$/kWh on the pack level. These batteries are rated for up to 10.000 cycles. That’s for the automotive industry, batteries for home storage usually are a good bit more expensive, at least for now and of course it’s not the price for the consumer. But I expect the prices to drop by about 50% over the next 12 months. At that price point you are down to 2-3 cents per cycle/ per kWh. That makes these batteries interesting not only for people who have solar, but also if you just have hourly tariffs or want to cut down your peak demand. Once people have the batteries, of course they will want to have solar as well.
The BYD Blade batteries are an exciting technology. I hope the car that they're being shown in, the Dolphin, makes it to the US market someday. Googling "BYD Blade batteries for sale" brought up a listing on a Chinese retail site for me. I'd be interested in seeing who goes first in sourcing them for a DIY solar project, or even a DIY EV project.
Yes, as soon as they put a dyson sphere around the sun. TBA next year. Stay tuned to this channel folks, this is history(onoics) in the making. ....Sometimes companies make these claims to throw off the competition, by making them spin their wheels in unproductive side ventures.
@@mikemotorbike4283 ?
Great video. I just subscribed. It's funny hearing you complain about how much that battery weighs. We installed our off grid system almost 6 years ago and went with flooded lead acid batteries. Our battery "system" weighs about 7500 pounds - so yeah that's heavy. I'm certain when we are forced to change out our batteries in the future, we can convert to a much lighter technology. I hope that's at least another 10 years out. We try to never drop under 75% SOC.
Great content. Just watched a few videos as I begin to learn how to build an off grid solar array for a new remote property. Excellent info!
As I watch you struggle with that Anderson connector it reminded me of the one I use on our aircraft. A 175 amp Anderson with a little bit of dielectric grease on it changes the whole dynamic.
a gentle touch and a bit of persuasion...
Thank you for this. I need see how stuff this size and voltage work and how they are built especially. Really appreciate it.
Im becoming a fan of the rack systems for batteries. Seems like this would work well in one if the screen was on the bottom. 2 people could then lift it and slide it right in. Still anything over 200 pounds is going to be cumbersome. Great video
We had three people to mount it on our workshop wall. It helps to have strong friends!
Yeah yeah we all know you just want to point and say check out the rack on that one......and then point at your battery setup.
Just an FYI, the company that makes these batteries is called Liniotech and are based out of Houston, Tx. The person you'll end up talking to is Chris Wang. He knows his stuff and will help you out tremendously.
Wow the packs are becoming cheaper and are big enough now to make sense for full house needs! Cant wait to see what the next 6 months will produce.
Checked the page. Is this true? "When the temperature sensor detects a cold outside temperature, it will warm up the cells first before it allows the cells to be charged. Without the sensor, the cells cannot be charged under 23F (-5C) and discharged under -22F (-30C)."
I am confused by that too. Mine has the sensors, but they were glued and possibly screwed to the bus bars, so I couldn't test them. I tried to, but I did not want to screw it up. Good point, I need to ask them about that.
Wonder if they just kick on all the balancing resistors to generate some heat inside the box or how they warm them.
@@WillProwse I second this, if you can test how the cold protection function works or get more info for a follow up that would be amazing.
@@WillProwse good point I live in the Panama City area of Florida were occasionally temperature drops below freezing. Is this a safe Marine application on a sailboat where there is vibration on the sailboat when the diesel engine is running. Second thought would this be a fire-safe unit similar to battleborn?
@@WillProwse Maybe use dry ice for cooling the sensors?
That connector looks like what is used to charge forklifts.
One thing I see that concerns me is how the negative group of cables is laying over the positive pcb. When going back to 2:20 I do not understand why there is the big loop in the negative carriers when they could have easily been routed straight into the battery area without looping over the positive side of the pcb. Strange. Even with the white plastic wire looms over that bundle of negative carriers, I am not comfortable. I have been a bench level tech and lo and hi V installer for many decades. Even in fixed applications, I try to avoid any near or cross placements of different polarity carriers. While I recognize that space is at a premium in this battery system, it only takes a few seconds for high amperage dc power systems to go very quickly into a disastrous situation.
yeah i wouldnt want to run this in an RV or anything thats going to vibrate
Great content as always! Please if you feel inclined, make an in depth video for us newbies on how to prepare recycled prismatic cells for a battery pack. I love to rescue, and it seems that the scrapyards really want to pawn off LiFePo4 cells to whomever they can. Roughly $2 Australian per kWh which still makes sense to me, even at a severely reduced capacity. All the best :)
✨Wow, that’s some setup. Thanks for sharing Will. I have learned a lot from your channel. Rog from Wales U.K. 😀🏴
Damn Will, that is one of the sexiest batteries I've seen you test. I love the fact you can see how many cycles you go through.. the menu is simple and informative. I mean damn. Itll be in my dreams. Well done and thank you for the excellent review. Particularly for lifting the skirt to see the cells 😋😛
Too bad they don't let you reverse the display text to work upside down.. or simply do a 180 degree flip on the physical display, and leave extra holes for buttons in both orientations. I would put hot melt glue down the back of the DC connector, so nothing could short it out that way...
@@Stubones999 completely agree
The 13.4 kwh battery looks like different technology it goes together in multiple pieces or module packs. Its internals appear to be completely different. Also with a 20year warranty vs 10 year
6kw max charge rate? you may look into old used cisco catalyst ws-cac-6000w power supplies they can do 6kw at 42v, but you can increase with a internal potentiometer to 48v or slightly higher (depends on what caps are installed 50 or 63v)
these supplies go for real cheap on ebay, i got one for under 30 bucks
but i think the 6kw is only for 240v circuits, 110v people gotta stick with 3kw.
its not constant current, needs extra stuff for charging batteries directly.
Looks pretty good. The price is a bit cheaper than my HSKY's even after the discount.
Not sure if I missed it in the video or not, but did this battery have a Low Temp protection ??? I need a system for an off grid cabin in Northern Michigan
Move the controls to the Anderson panel, and rack mount it. Also would be intrigued to see the thing at max discharge and max charge under a flir cam
I wonder how much longer DIY batteries will make sense. These look really nice. 20 year warranty is impressive if real.
Could you look at some low-use appliances: fridges, water heaters, dish washers?
RVs wanting a heat pump: I saw a 12v DC mini split on Alibaba. It even connects directly to solar panels and a battery, or it can do 120v when DC is low if 'the sun don't shine'. 12v DC would be great if you already had a 12v system.
@@mikemotorbike4283 any chance you have the link? I can see some but not sure it connects to solar
That’s really cool I am definitely looking forward to seeing more videos on these battery packs and hope to add a few to my system as well.
People’s minds will be blown when they find out how similar this setup is to power wall V3
I have learned _so_ much from this channel. Thank you quite a lot :-)
What enphase do right is making them modular. That eliminate the need to move something so heavy. Further, it is expandable and component replaceable. What really needs to happen is to make all in one unit easy for consumer to use, install and maintain. It needs to be modular, otherwise too heavy. Your videos are great.
Thanks Will! Another epic video! Be well
In the Denver metro area you can go to grid Alternatives and you can buy used or slightly scuffed panels every one of these modules is of the newer class 315 w so something to look into they only charge $20 per module
Hi Will, I think your tube channel is brilliant. As a Brit thinking of attempting to go off grid, I would love to know if the battery units on your channel are available in Britain.
So would I as I'm thinking the same thing. Also from the UK.
The only issue with US units is in the inverters as they all output 110v instead 220 (there are some that do 110/220), but be aware… regarding batteries and battery packs, you’re safe to use anywhere in the world
Any recommendations on larger 48v inverters (20, 30, 40 kWh and larger)?
Besides being more expensive, how does this compare to the EG4 over at SignatureSolar? The 5KWh of this costs $2347. The 5.12KWh EG4 "pro" costs $1749.
Another great video. Thanks Will
They are almost the same product but one is more expensive. That's all.
I have two of them and they are working flawlessly in my off grid system. I paid $2500 for them though
Where did you get them for so cheap???

Being that those are relatively small cells, as in a very shallow design, that may facilitate the horizontal orientation. Bigger cells may be more susceptible to orientation issues.
Advertising to the manual, it states must be mounted vertical with no more than max 15 degree backwards tilt

102.5 kg is a beast of a battery. Stay lucky dude 👍
Hey buddy!!
great videos & info.
will watch later when I get time
thx for making these :)
The weight is normal for LiFePO4 batteries. It is heavier than nickel cathodes by like 25% but worth it IMO especially for stationary storage!
I feel like i am a Bank Robber & i just open the VAULT!!!! lolololol. Love this guy. Never a boring moment. Very good Information for us all. Keep up the great videos & Testing.
I stay away from spot welded banks.
Like you said, no easy way to replace a cell if it goes bad.
hello, regarding Anderson battery plugs they easier to plug in when the metal connectors are greased, classic lithium grease will do.
Will. To set things up, I worked in San Antonio, Texas years ago where I worked in shipping containers that had been converted into storage. The temperature inside of those things would reach 120 to 130 degrees F even in the insulated containers. There were even a few times that they approached 140 degrees F. All of those containers were water tight and little air circulated through them. The containers that I worked in had open doors. God only knows what the temperatures would be with the containers closed for several days or weeks.
Listening to you and others that review DIY prismatic cells two common threads are that the ones from China are weeks and months in shipping and quite often the cells that you all recieved were puffed up. More than likely, they were shipped in containers like I described. I have two questions in relation to this information.
First, knowing that heat is bad for Li batteries, would the heat that I have described be harmful to cells that are in transit for weeks and months?
Second, would a person be better off paying shipping fees for faster transit so that the cells that arrive have not been cooked for days and weeks on end?
I know that grade B cells are often pawned off in other countrys by Chinese firms, but how long could they really get away with that practice before word spread and they couldn't sell in the US or Europe? For those reasons, i belive that at least some of the problems that we see with battery cells out of China are the result of poor shipping practices. 'What do you think?
Thank you

Just a quick question as I'm ignorant. You can parallel different types of lithium batteries together in one system like that safely? I'm only asking for my own experimentation. Thanks for all you do!
Thats still mighty pricey. I paid $1500 for 8kwh, but to be fair, i had to assemble it my self and it does t look as pretty. All parts considered, i still paid half of what they are charging. Assembly is simple - get batteries, assemble on a flat surface, with 90degree angle to butt it up against. Glue cells together temporarily with hot-glue. Order nickel strips, cut them as needed, build basic welder using a button, car starter relay $35@local parts store, and some thick copper wires mounted on a wooden block. Use car battery for the power source and get a solid fuse to prevent stupid mistakes. Get hole saw, cut holes in the right places on a couple 2x4. Cut 2x4 along cener through the holes to provide a top-bottom supper. Sandwich between two ply board cut to right size, leaving room at top to mount BMS and DC fuse. Connect wire, add a connector like the one seen in the video and bam. Ive made 17kwh of power my self. Couple to 6000w of solar panels and midnite 150 solar charge controller. Make a LVC using $12 programmable delay with thermistor connected to the normally closed side of the board relay, and a 12V 100A relay connected to the normally open side of the board’s relay. This provides a soft start/inrush prevention to keep from damaging the inverter, and prevents the relay contacts from welding together, so the charge controller can shut off reliable when the voltage gets too low. I run two AC units, one that draws 1.4kw and one that uses 1.1kw. The second AC unit only comes on when it gets really hot otherwise its not needed. When the sun goes down i normally have 15-16kwh of power to: charge my neighbors car with the excess, run my two computers and do a number of things. The BMS has thermal cut off, but because the system is capable of taking in 3.4kw of charge at 1C, and charging never exceeds 4.8kw, the batteries NEVER heat up beyond 31C, in the summer, under full charge load. These batteries wont heat up appreciable until they reach 1.5-2C charge rate, which my system never achieves. If you are a DIYer, dont waste your money. Takes a few days to put the batteries together, a few days to charge and test. Batteries come charged at 3.2V per cell. Charge pack until any of the 16 rows of cells reach 3.45V, then using Variable DC power supply ( $50 amazon), charge each row to 3.65V and wait till final charge rate settles to .07A, perform this once more for each row 12hr later, then bolt the shell together. Bam. They are ready. BMS will balance them from here. Its been a year since my last balance and the batteries still dont need maintenance. If you have time and have the skills, dont waste your money on something like this
I love this... inspiring others. Congrats Will you deserve this, nothing come for free !
Safety glasses always! I know you know but you need to remember always so this is just a friendly reinforcement.
Looks like they changed the design for the 48v 13.5k. The packs in the pictures on the website show the pack up right in the case like you said is the normal position.
I love watching your videos you have so so much knowledge your a very smart kid
thinking that with them flat you could rack mount them together you could stack more in one area
Thanks for the illustration on why you wouldn't want batteries lying down. For the build I've been thinking about, that's how I wanted to lay them (flat, side by side) as I wanted something as short as possible. I will have to think on this more.
How do you parallel the different batteries without huge power going through it to level the voltages? I assume lots of amps would flow because of the difference in voltages. Or you exactly matched them before?

Iv'e noticed a lot of people offering larger batteries, it's like the last push before prices bottom out.
One of the issues with these batteries is the low C rating requiring multiple units to run a larger system.
Requires one unit to run a 3 kW Inverter.
Requires minimum of two units to run a 6 kW Inverter.
Requires minimum of three units to run a 12 or 15 kW Inverter.
Paralleling requires an additional cable (not included).
It says 120A discharge in manual. So 6000watts. I'm pulling 100A into mine no problem. Seems fine. Must be a typo
Their site may state that but we have had zero issue running a single battery to power emergency items in a power outage. Its connected to a Outback Power 8048A
I like the heavy packs because they are hard to steal
Another awesome review video Will. Thank you so much - you give us DIY'ers a lot of confidence to do this ourselves.

I’m not seeing anything saying who makes this battery????
With the location of the handles on the panel, it appears that it is designed more to lay in a rack, rather than hang on a wall.
This battery is branded with different names..most examples are wall mounted..it would make more sense to have the connections at the top for wall mounting.
It's crazy that batteries like this and better will be so common of the next few years. Just going to get less and less expensive per kWh!

Yes, good idea to add a fuse in that cable if you just have lugs on one end. Does it have an internal fuse? Anyway, thanks for the review. I think I'd rather get two of the 100AH batteries, I don't have a pallet jack (but have a better hand truck than you!). :-)
Got a 5.3kwh battery setup from bigbattery this year. I decided I wanted to add another one for capacity recently and they dont even barely have any batteries anymore for this entire year. Wish I would have gone with a larger battery setup like this from the start.
I definitely want to try 2 of these batteries, the 13kw variety. They again seem high as the devil but such a nice design for storage. I have 48 280 cells setup for 840 ah using Daly Smart BMS units. Annoying that they do not talk together as one. Adding 2 of these or even 1 would complete my requirements for daily power. I also ordered one of your chargers from SS. The 48v 25a one. I can\t wait to test it out on this large bank.
This helps instill comfort in smaller projects
I thought I was back in my telephone days since -48v is the operating voltage for most equipment
why you did not show the full connection of the system
Wonder if this type could work in a RV oriented flat on back on a solid floor? It appears the cells should have little movement and cell bussbars have between cell bends to allow some movement, probably for cell expansion.
