Yeaahh I saw “Load tests” on the tittle and quickly started watching!!! Love these vids mate... good to see your packs working really good, Batrium makes everything super visual and easy!
Nice work, people always ask for full capacity tests but very few actually do them! 5:45 That timelapse was fun to watch, interesting to see how it decreases over time and those few packs completely dropped out fast at the end. 7:30 holy crap that's a lot of maths
Going to upload the whole 64 hour timelapse at 100x speed, about 40 min long but some might want to see more detail. No one has called me on my mathing either so looks like I did well lol
Well done Pete, that was a really good demonstration. I noticed a bug with the Batrium kWh display - it wraps after 12.87 kWh so can't display the full 30kWh Suggest Jaron could increase the precision and use more bits for it.
Issue was 1. Cell went flat, causing no comms to watchmon toolkit 2. Found a bug in the firmware that caused the shunt not to reset after it goes to 0% SOC - 20min on the skypes to Jaron and he was able to find the issue, make a plan to upgrade firmware & test on his test bench. Fix was to change the SOC level - save - then it's reset and away to go again.
I think there is more in them if they were more balanced packs. would be very interesting to balance them at 4v rather than 4.2 and see if the cam useable capacity would be available. So many cool tests i could do but i feel like i'm missing a leg running the house on grid
Hello..Great video.. Just want to ask what is the life of the diy powerwall ie charge discharge if you are using it for day and night..ie charging in day via solar and using in night. Cheers 😊
Have you thought of making small say 5 to 10 cell piggy packs that you can fit to your lazy packs? This way you don't have to dismount and knock cells out and replace, could save you some time and handy if you need quick fix. Might look a tad messy but would work.
Reality is that although the Batrium looks nice it will never handle your charge rate capacity of your your solar input. The only way you can handle those inbalanced cells with those charge rates are higher power resistors. Im working on my on balancing circuit using some 100W 0.2ohm resistors.. That will bleed 21 Amps.. That is still not enough when you get high charge rates and one bank gets there earlier than everyone else. Nice test. Love your work. Use the batrium only for monitoring and not for balancing unless you modify them to switch a larger resistor as said.
I beg do differ, Batrium works SWEET - but throwing 150 charging amps at it.... will find issues fast. I was brutal trying to get them chared as fast as possible.
1.7amps max bleed isnt really appropriate for 600AH cells.. Even with a 20amp charger for eg... If you have 20amps going through your batteries and one bank hits its 4.2V limit you will soon run out of bleed capacity if the other batteries havent caught up. Your charger will be pushing for your CV limit forcing more bleed through the highest charged batteries discharge resistor until the rest catch up and the the current starts to drop.. Thats just my thoughts.. especially when dealing with lithium. :)
the 'cells' are 150ah so perfectly suited for the job I feel (and has been my experience) Chargers ramp down when they are top of charge so never pumping more than a handful of amps by that time. My issue was the dumb way I did it in order to get a result faster
was thinking, its dangerous i know, but some sells cut off at 3v so while the packs that dropped really fast might have cells that are cutting out as they dropped below 3v giving a miss reading as the packs get smaller with cells cutting out. just a thought.
do you use this in real world application or is it just for testing? I mean do you run your house or business on these batteries? How much do you save on your electric bill?
Every day/night for the past 2 years it's run my home - Never worked out exactly but it would be a fair chunk as we average 20kwh ish per night + day time use direct from solar so maybe 30kwh per day
Longmon or Cell Monitor is attached to each 'P' pack and is the balance and temp monitor - watchmon is the hardware brain I guess you'd call it making the longmons smart and controlling all the other stuff.
You sure can - few points you have to check tho - if a cell is 3300mah new and when tested it's 1800 mah you wouldn't use it. You can use the cell data base to find the required cell info secondlifestorage.com/celldatabase.php but if the cell was new and 1800mah & after testing it was 1700 it's good to go.. Just make sure you build balanced packs with repackr secondlifestorage.com/repacker.php too keep the built cells more balanced
Couple of questions. I learned the hard way that what often looks good on eBay is a lie. I did order 4 batteries the other day from an eBay seller that the price was good. The weighed out at 45 grams and tested at a solid 2100 mah. They were though button top batteries and if i remember one of your videos it was mentioned that button top was a sure sign of repackaged batteries. I was thinking of buying a couple hundred of these batteries. Should I steer clear of these even though they check out pretty good. Also how do you connect the top and bottom black plastic organizers together so everything doesn't come apart? Thanks
Clearly you've watched all my other videos before sounding dumb - this is/was/will always be an youtube project - 10k in front so far - 'Cash Positive' You better believe it! Best thing i've ever done!
HBPowerwall the whole thing man, turning recycled laptop batteries into a full house power pack. Very smart. Done lots of mining myself but cost me £1000s in electric. Wish I had sold my bitcoin at the Peak last year!
Yeh, I'm really enjoying this new journey & the mining with solar appeals to many. My last power bill went from 400 to 1100 for three months from mining but so worth it still.
Hey guys a complete noob here,im having some doubts on 18650s Im thinking about making a powerwall and confused on some things One of those things is that what would happen if we connect batteries of different capacities in parallel and charge them as a single system, with bms within the multiple series connection (making multiple parallel and 4 series connections to make 12v battery pack) Such as connecting 2000mAh battery with 2600mAh battery Thanks
Hey Pete, quick question. What if all your stacks were 6x20 instead of 4x20? Wouldnt that give you about 50% more battery in about the same amount of shed space?
Bitte keine Bitcoin-Rechner bei Powerwall zeigen. Das gehört in ein eigenes Layout. Nicht jeder ist von Bitcoin begeistert. In so eine First Class Serie gehört nur Solar+Zubehör, 18650, Regelung, Aufbau und deren Steuerung.
Batrium, I think it's pronounced bat as in battery, bat-tree-im not bait-tree-im, like catching fish. There's no i in there. There's that and the shit music otherwise great vid!
Yeaahh I saw “Load tests” on the tittle and quickly started watching!!! Love these vids mate... good to see your packs working really good, Batrium makes everything super visual and easy!
without batrium toolkit and BMS these videos would be boring haha Can't wait to see what else is to come from them!! Exciting times ahead I'd say.
Holy crap, a 31.5 kwh array made up of salvaged 18650s, you are a legend sir.
That was so long ago, done 3x that now lol
@@HBPowerwall Whaaa seriously? Almost 100 Kwh? What do you need that for? I can't imagine you have more than 15 KW of solar.
Nice work, people always ask for full capacity tests but very few actually do them!

I love your in depth testing videos. It really helps get my head around troubleshooting techniques needed to support a DIY powerwall
Certainly was a massive one to do - ended up with over 150 hours of footage! Really hope it helps !!
Great work Peter! Youre a good inspiration. So much so i built my own 14s100p 18650 pwall on the sunshine coast. Cheers bud and keep up the good work!
Thanks for taking the time to comment Boboo, Encourages me to keep making videos :) This one took a while to do hehe
Exciting test ! I always wanted to know the monitoring software you are using, now i get it.
Www.Batrium.com BMS
Very good work Pete.
Thanks John :)
I Love what you are doing and how hard you put in. and you know what you are doing to
Nar still don't know what i'm doing ... or rather did - fun learning curve
Dude, outstanding! Very nice project, love it.
I really loved doing this one even tho it toook ages and ages to film & edit ! feel free to share !
Thanks for all the information. Great system.
Thanks for tuning in :)
All the respect for your project. I wouldn’t take a huge amount of cells inside my house. Charging my ebike outdoors as well though storing it inside.
Neither would I ... never happen hence it's out side in their own sheds :)
I am happy watching your video .
Congratulations brother
Thank you so much 😀
thankyou Pete. From Pete in the UK
You're Welcome Pete :)
Well done Pete, that was a really good demonstration.

Do you have a blueprint for the project
yay load tests !!!
I really like the results of this one - but dam it takes a while
If you were to supply your tiny home or mobile home, is this how you should cycle these style battery packs?
i guess so, i used about 25% of these every day for past 4 years
I really need a Batrium!! Holy Cow, it sure looks like it is 100% helpful!!Great Video!!
Much more than a Chinese BMS that's for sure!
One of these days definitely! I probably wouldn't stop watching it!
with out a doubt it's like TV - constantly check it even tho it's not needed
I thought that you have more capacity in your packs.....
Excellent video by the way... 👍
I think there is more in them if they were more balanced packs. would be very interesting to balance them at 4v rather than 4.2 and see if the cam useable capacity would be available. So many cool tests i could do but i feel like i'm missing a leg running the house on grid

Hello..Great video.. Just want to ask what is the life of the diy powerwall ie charge discharge if you are using it for day and night..ie charging in day via solar and using in night. Cheers 😊
four full years so far, and still going strong 400ah used last night, they'll be fully charged by 1pm ready for tonight

A tad messy, is my issue lol I have done it several times different ways - just looks crap :)
HBPowerwall yeh, my cells are hidden away so not such an eyesore. Just take the piggy backs off for the photoshoots :)
Too lazy lol takes long enough so move all my shit from the past weeks work to film lol

Awaome experiences with this power wall
They are amazing
Pardon me , whats that monitaring program your using for the system
do you use this in real world application or is it just for testing? I mean do you run your house or business on these batteries? How much do you save on your electric bill?
Every day/night for the past 2 years it's run my home - Never worked out exactly but it would be a fair chunk as we average 20kwh ish per night + day time use direct from solar so maybe 30kwh per day
Is that 14 packs in series within each of which all cells are parallel?
spot on
May i know name or brand of DC cable you are using soft cable
it's 35 square mm cable from the local welding supplier
HBPowerwall thanks a lot mathew same with me what u used
is there an arduino/open source alternative to Batrium? for 1865 management? Running a much smaller (for now) pack.
I would hazzard to guess there is, maybe on github or the like - have to be something out there.
Awesome! Is this now 56 packs? What is your configuration now? Used to be 14S 14P ??
56 x 80cell packs - 320p 14s
Cool! 320 packs each with watchmon or is it watchmon fitted only on 14S?
Longmon or Cell Monitor is attached to each 'P' pack and is the balance and temp monitor - watchmon is the hardware brain I guess you'd call it making the longmons smart and controlling all the other stuff.
Can you mix 1700mah with 1900's, and 2200s? What is the lowest you can use in a mixed cell block?
You sure can - few points you have to check tho - if a cell is 3300mah new and when tested it's 1800 mah you wouldn't use it. You can use the cell data base to find the required cell info secondlifestorage.com/celldatabase.php but if the cell was new and 1800mah & after testing it was 1700 it's good to go..

what were your cells you bought sold as 2100mah? As for building packs try this play list - th-cam.com/play/PLVtgHS9JIte_tT8JVGvoK3OBy7sYm3Xwj.html
Never mind, the diameter is too big to fit the black plastic racks.
nice test for mining coins on a 2nd hand battsmmgreat video man..thumbs up!
thanks heaps Monckey Wrench!
Hi can show me line for BMS Where do you buy it thanks
www.batrium.com is my BMS of choice
Spends thousands and thousands on equipment
Makes 50c

Great Stuff
Thank-You
hi grate video i got a question wear i can get the termal device you got. lead me know so i can get it to tanx. keep the Excellent Work.
Thermal camera or the software to monitor the batteries?
the camara if you can tanks
It's a Flir unit - goo.gl/3FJmGL
Very clever.
What part did you find clever - the load test with a miner?
HBPowerwall the whole thing man, turning recycled laptop batteries into a full house power pack. Very smart.
Done lots of mining myself but cost me £1000s in electric. Wish I had sold my bitcoin at the Peak last year!
Yeh, I'm really enjoying this new journey & the mining with solar appeals to many. My last power bill went from 400 to 1100 for three months from mining but so worth it still.
About how many days does it take to mine a coin of ethereum, with you're setup?....good video BTW
In that time i mined 0.012 eth i think (it wasn't much)
how much did you make from the rig while it was testing for 64 hrs?
Info is in the description i thinks, mobile atm
Probably made more money from TH-cam ad revenue that from mining lol awesome video
YOU BETTER BELIEVE IT lol SIX F!@#$%^&*()ING BUCKS! lol
Dayum. If you're ever caught in a power outage for any significant length of time, I think you'll be pretty set.
Reality is that we have only lost power for maybe 20min max since my wall was commisioned :) Desperately waiting for a longer outage lol
HBPowerwall
Lol. Usually up here the power can be out for a few hours to a good part of the day.
Where you located?

guys any chance of making 24v 18650s 5kwh usable powerwall avoiding bms or keep them at cheap as chips :D
Yep, but not cheap, and never with out Quality BMS
gaming for life wow :0 this dam thing is awasome :D
Love those things!
I'm amazed,I will learn those thingd,serious,you its a genius!
I'm just as amazed as you are that it works so well
How much money did the miner make with all that energy?
Probably not much from memory
What are bitcoins anyway?? And what is mining them ??
Made up currency designed for drug dealers and computer nerds
@@HBPowerwall Sweet how do I get started 🤗🤗
@3:22 Seems to be that this is a global problem ;-). Nice to know ;-)
LOL!!!!!
i said it in another video, but i'm loving this dude ... obligatory "no homo" :D
wow :O

600 kwh he says hahah lmao
got lazy and hoped no one noticed lol well spotted
😁✌🖖👌👍😎

Please don't use this to mine coins your 5 years to late! You would make more money selling your power to the grid.
How it’s off grid ?
i BET YOU WONT SAVE ANY MONEY EVEN AFTER USING THIS FOR 10 YEARS..yOU INVESTED SO MUCH IN IT-AND IT WILL KEEP ON JUST DRAWING MORE MONEY..lol
I'll take that bet.... then i'll link you to P&L statement then i'll take ya money
Heck I'll just point you to the videos I've released months ago .. remember that is is a youtube project :)
Batrium, I think it's pronounced bat as in battery, bat-tree-im not bait-tree-im, like catching fish. There's no i in there. There's that and the shit music otherwise great vid!
Love my music :P i think the editing software + speed i talk mush it up sometimes thanks for the comment
