Have you seen this new battery and would you be doing a review? Only seen it on Amazon. Repower Flow 24V 100Ah Lithium Battery Bluetooth, Low Temp Cut-Off, 24v LiFePO4 Battery, Built-in 100A BMS
Got a LiTime mini as a freebie and had some questions for the manufacturer; they were right on top of it. Gave me my answers in a quick and polite manner.
FYI, they have a $70 off coupon on their website for the Bluetooth, I just ordered 2 for my boat and got them for the same price as the trolling motor battery
Of course this comes out after I already went with EPOCH set up lol you’re gonna love it…troll for 2 days straight on 50% capacity…way better than lead acids…didn’t have to trickle charge mine all winter.
Thanks for another informative video. And thank you for the information about balancing cells in the batteries. I full-time in a motorhome and only plug it into power twice a year. It’s nice to hear someone with your knowledge that I agree with in saying that everything doesn’t have to be perfect as they still work fine. I hope you are still enjoying your GT4.
I just bought one of these LiTime 100Ah Bluetooth batteries (due to be delivered in the next two days). I'm setting it up for power on a squaredrop camper build. I'll be running 200W solar for off grid camping, with a LiTime AC charger as backup if needed. Only running a small 500W inverter (who needs all that power while camping). Thanks for the great review!
I spent this winter camping in Quartzsite Arizona and used two BtrPower 100AH batteries. They worked just fine and definitely got the job done. 187.99 each on Amazon right now.
I bought a two pack of the100ah group 31 for my truck camper to replace the two AGM'S. Running a 3000/6000 peak inverter. Bought them for under $500 with a $70 coupon on Amazon. No complaints so far
Cool update: How about a video about replacing the AC and DC distribution center for RV house with lithium battery ? Most WfCO power centers are for lead acid batteries.
WFCO now sells a retrofit charger for their power center. I called a couple of days ago and for my Mo 8955 power center, the retrofit PN is 8955-AD-MBA. $105. Read the Amazon reviews.
If you are installing batteries in boats to go offshore, bluetooth is very useful. Being able to monitor the battery at cell level my head off any potential battery shut down in advance.
I have 3 litime batteries. I’ve just had one fail after only one year of little use. 100 size. I have contacted their customer service and will update on how they handle warranty.
One last comment , I forgot to add. Li Time allowed me to return my two questionable batteries. I will consider buying their product again. Very easy to work with.
Great stuff as always. Question / Content suggestion - for those of us who have older portable solar generators and are looking for additional capacity, can you come up with a way where we could interface a battery such as this one to the existing system? Perhaps where you could plug this battery in the solar generator 12v or 120 AC output to charge, and have a small inverter from this to plug the main system into to charge it. I hate to throw away the older, obsolescent, but still functional system until I've worn it out, which likely won't be for 5-10 years.
Hi Litime mini will always run my toaster up to 122 A. I thought it supposed to cut off at 100 A why is that ? it goes through my 2000 watt pure sine inverter. Shunt says 122 amp
I just got this from amazon it was $199 - $16 coupon - $20 promo code that brought it down to $164. Free fedex shipping. I'm using it to extend my powerstations (got an ecoflow, a jackery, and an vtoman) with buck converters 12-24v it plugs into their solar inputs. Works great. I bought litime's $79 20a charger with it. Thinking of getting another one. This gets kinda addictive.
Got a 50Ah Li time the other day, wanted a lighter battery for fishing kayak tolling motor. Got a led acid 77ah and i got the same range (or more i was done fishing) 1/3 of the weight and 1/2 the zise. Im happy
Would you suggest another solution to monitor the battery if it doesn't have a Bluetooth module? Something that could display state of charge, voltage for example?
@2:43 the 291 A inrush is not almost the max of the Inverter (300 A *rated*). That is that inverter's max for the test condition (temperature, current slew rate, etc.). 3% low. I would expect an unpublished spec of +/- 5 to even 15% for a decent quality inverter. There is a tolerance at round that 300 A, an it is the 'max' so its nice that it tripped before it.
For your information: it donst realy need your location but the battery is using Bluetooth low energy, that was invented for indoor positioning - this is why the permission for BLE on android is called location pernission :D
I would love to see you take apart a bunch of 150Ah batteries for those of use that are limited to a group 31 space and are trying to maximize our usable battery capacity. So far I'm not finding many of the manufacturers that you even marginally recommend making them, but their size and capacity really interests me. It seems to me if a group 24 100Ah interests people a group 31 150Ah would appeal to an even larger audience...
Nice review. A real world test of the Li-time surge in will it start a car/boat several times. The conventional wisdom has been not to use LFP for such high surge loads, but it seems that the higher capability BMS’s might be able to change this. There is still the alternator charging challenge but that is a solvable problem for those of us with boat/RVs
Just wondering if you had two in parallel, could you use them to start a small diesel. I have a 9 hp single cylinder Volvo in my boat and wanted to switch to lifepo4 batteries.
The “don’t use lithium as a starter battery” has always been about temperature. Gets too hot in most engine bays to the point where degradation is significant in short periods of time. A123 cells, cylindrical and pouch, have been used by some car manufacturers. You don’t need something with such crazy high C rate though. Your average prismatic cell can burst 3C-5C for a few seconds.
I went with the cheaper 12v 100Ah regular batteries, not the trolling motor ones. I live in the south so don't need low temp charging protection. I did add a Amped Outdoors smart shunt for $60. When using them for trolling batteries it's good to know your drain and SOC, especially if you are fishing a multi day tournament without the ability to fully charge between days. So, $80 to have it integrated isn't really a bad deal.
I have a Li Time mini. Can I use it with a trolling motor? Li Time says I can. Also- I charge it with a 5-amp 14.4-14.6 volt charger. My battery charges to 13.7 volt. It never reaches 14.4 volt. Is my battery bad? They said I could return the battery at my expense, but insist it is fully charged. Are the cells not balanced? and the cause of the problem.?
My minis only go up to 13.8V with a 10A charger attached. So very likely that there is a balancing issue but I pulled 105Ah out of both so it’s not so bad that I’m missing out on capacity. You probably have a similar balance issue. If one cell is hitting 3.75V and the rest are at 3.45V then you’re getting nearly 100% capacity from those 3 “low” cells. Might be missing out on 5%
Apparently heat is the issue; if you can keep the battery around ambient it may work OK. I used those little motorcycle lifepo4 batteries (e.g. btl14a240c) as starters for my 2.3L sedan in SoCal (warm climate), but both the first and second one failed after about a year, possibly due to being run down or overcharged (the BMS was exceedingly primitive, appearing to only do balancing). The cells were all puffed out when I disassembled them.
great videos, i feel a lot more confident buying a battery now that you've opened so many of them up and can actually see the build quality and guts ... can you please post a link to the chargers you are using ? thanks !
The user manual says not to use it as a car starting battery. Warm temps and quick starting might work, but cold temps and hard-to-start draws more current for longer. No need to push the limits when a cheaper L/A battery is optimum for car starting purposes.
I really enjoy your channel. My son & I want to add a PV system to our sailboat. We are undecided about staying with 12v or into 24v someday we’d like change to an electric motor. Any advise?
id love a video on "solar array grounding". i noticed you havent covered grounding the array in a video, just inverter grounding. im curious if grounding the inverter using ac input also grounds your array thats plugged into the inverter but im doubtful.
I just ordered two litime trolling motor batteries look forward to trying them out on my boat lift and for trolling motor applications How do we know these ultra cheap batteries really have grade a cells. Also using an Ionic lithium diesel starter battery in my dump truck Replaced three lead acid batteries Starts the truck great charging with the stock alternator Thanks for your channel
I’m struggling with my 24v system. I have two charge controllers for each solar array. It’s been working fine up until the other day, now the Bank one controller stays in Overcharge mode while the other Bank controller charges normally. I’m stumped!!
For my simple trolling motor I have 12volt lithium battery with bluetooth app. Wouldn't be without it! There, I can always very easily see the SOC, and how long I can drive at different speeds before the battery is empty
I have a 50 HP Yamaha 4 Stroke Outboard with an alternator. The starter requires less than 285 CCA. I realize LiTime offers a 12v 20ah Start Battery with 650cca, but wouldn't a group 24 or 31 be a better battery in the long run? I plan to use 120v shore power to a Lithium charger keep it charged up. Is the issue the Outboard Alternator? My friend that works on RV's recommends that I use a group 31 led acid and not use Lithium LiFePO4 at all.
Buy a DC to DC converter. I have the Renogy 40 amp DC-DC charge unit in my van. This is the one without the solar input. It charges a 300 amp hour lithium battery with 2000 watt inverter. It needs a separate wire to any car circuit that turns on when the key is on, otherwise it will drain the car starting battery with the engine off. My ignition sensing wire goes to the windshield wiper circuit, easily accessible. The DC-DC unit has another small terminal that will cut the charge output current in half when its energized. I installed a 3 way dashboard switch, up gives a full 40 amps charge, neutral is off, and down on the switch gives 20 amps to the lithium battery. This comes in handy when the headlights are on, heater is on, and windshield wipers are going. At a stop light, all of this overloads my 105 amp alternator and the voltage drops to 11.5 volts. I switch to low charge, 20 amps, and the engine alternator will be at 12.8 volts at idle. Other Renogy DC-DC charge units come in 20/10 amp, 40/20 amp, and 60/30 amp sizes. There are dip switches on the Renogy DC-DC charging unit to set battery type. The current into the lithium battery will reduce itself until the battery is at 100% charge. Then it cuts off charge current to the lithium battery automatically. I also have solar panels and opted to have a separate MPPT solar controller. The new combination DC-DC charge units don't put the full output to the battery. They share solar/alternator output. They also can't handle more than 24 volts solar input. My panels put out 96 volts. I hope this helps.
Hello, I purchased the Mobile book, now the question, what is the max Watts I can produce for a mobile system and still run the campers 12 volt system? I am versed in electronics and avionics, but I'm not sure of the MPPT I will need and running 1680 watts @ 30 amps.
I like flush mount terminals like this one has! It makes cable routing and connecting so much easier compared to the to the style terminals that sit in a small recessed area of the case.
My epever BN series button keeps tripping out on my 12v circuit but my 3K inverter is not affected, any ideas Will? The manual doesn’t mention when or why the button trips.
I’ve installed 2 group 24 batteries to replace my LED Acid on my 28ft RV. I fully charged them and tried using them. One of the two batteries will not show discharge and remains in standby according to the APP when 110 is disconnected. I’ve purchased a 3rd believing the battery BMS is bad but it’s still performing the same. Any suggestions as to what’s causing this?
Sorry I really can't find an answer for this battery. Will a mppt controller die if example this battery (BMS) cuts of power and the mppt controller still receiving solar energy? In another video you are telling that, we always have to connect the batteries first, to avoid failure. But what if the battery just stops working? Will it then cause fire or destroy the controller?
I bought two of these to add more AHr to my Camp Trailer. As received, they came "charged" at 3.4 volts. That made no sense to me. Their email from their tech support response was fairly quick. I was told to charge them. I used a NOCO Genius 10 A charger. They seemed to charge but I found some discrepancies with the app and my voltmeter. I still want two Group 24 batteries. Has anyone else found issues like mine? What is an alternate high-quality Group 24 battery. Bluetooth is not mandatory as I have a Victron Smart Shunt. What about the Vatrer Group 24 w/ Bluetooth?
No kidding! Seems like Will is out of ideas! Maybe he can start converting cars to electric or something like that with his knowledge. That will be very interesting... Or build up off-road car including the frame from ground up... Or electric ATV or something?
@@empower88 I'd love to see him wire up a system using auto salvage parts. My battery cables came from two crashed audis at the junkyard, I took the battery cables as they are high quality and long because the battery was located in the rear of the car.
Are there any bluetooth apps for this battery that have more visibility and control? The litime app works, but doesn't tell you much, or have the ability to graph long term data, change cut offs, etc.
Thank you Will! There aren't any lithium batteries that can be used in place of an engine starting batteries, correct? A lithium would need a kind of DC-to-DC smart charger in between the alternator, yeah? Thank you!
@WillProwse i bought one of these after watching this video and researching a ton of other brands. Got it, and I have not used it much, and the Bluetooth module is having issue, doesn't report properly and "glitches"... no response from litime support. I have read that they are not very good at honoring their warranty... any ideas? Will the eventually honor their warranty? I have purched so recently i could likely file a claim with my credit card company in the worst case.
When running these batteries in series, do you need to worry about balancing them, or can you just charge them to full charge before hooking them up in series, and be good? And if you do use a balancer, and I undestand balancing LiFePO4 batteries correctly, the balancer should not be left connected all the time, but only a couple times a year, or if batteries are drawn down to near empty? Talking about a trolling motor application, so the batteries will get a full charge after every use. Thank you!
@WillProwse Question: I have a stack of 6 EG4 batteries BMS communicating with my growatt 12K inverter. Theoretically, shouldn’t I be able to attach more LiFePo4 batteries in parallel without them being connected to the RS485 comms? I have found a different brand of rack mount batteries at a better price but they lack any wired comms. I understand the accuracy of the SoC may be affected but the internal BMS of the batteries control the flow of current and maintains safe conditions, correct? Buying matching batteries at the same time is always ideal but building on a budget is sometimes necessary. Thanks for your time!
Hello! Can I use this type of batteries connected in series? I want to connect in series for a disabled electric wheelchair? Is it suitable for something like this?
Haven't actually done it, but the manual includes diagrams for up to 4 in series and 4 groups of 4 in parallel for a total of 16 batteries. Says use identical batteries and there's some comments on balancing them before connection for 12-24 hours.
i just got 3 of these .. charged with noco genius for a bit .. BT came on .. app said each was about 50% charged. Powered them OFF so that I could wire them up in parallel in my trailer without sparks... now I can't figure out how to power them back ON... manual says just charge them, but my noco charger refuses to charge as it doesn't detect enough voltage .. because they are 'OFF' .. so scratching my head as to how to power these back on .. there is no on/off button :(
@@richardeverett1227 the app needs BT to be active, which it isn't .. as the batteries were 'powered OFF' ... In the end, we managed to wake the batteries up with an 18v DeWalt battery and some wires... then all was good... BT came back on, app connected, inverter came on ... mppt came on ....
@@miramar-103 Good to know. I have a lot of lab power supplies that are current controlled, 0 to 4 amps, 0 to 30 volts so I guess I could wake up the bms fairly safely with one of those if it ever happened. I thought the BT would be active always even with the battery off, since it likely just uses a milliamp and would take a century to drain a 100ah battery.
I was thinking of getting 4 of these for a 48v Ryobi riding mower. Small yard and so thinking 50Ah. Any thoughts of doing 4 of these in parallel and pulling amps to run a mower?
I've heard from many sources that LiFePO batteries can be oriented in any direction. I just got 2 - 100aH batteries from Li Time, and the literature says to have them upright or contact them for other options. Upon contacting them, they said I could use them on their front but not on their back. Does anyone have an explanation.?
Thanks for the review … clear concise and factual. I was scared to buy a pair of 230 Ah Li Time batteries for $970, since it was 1/4 the price of battleborn (seemly the Cadillac of this category). Any thoughts on if this is a good plan?
What about Eco worthy lifepo batteries? Do you ever try them? I been running then on my home and been very happy , they run my home 95% with the rest of the solar system.
Nice job Will Li Time makes a complete line of products for solar enthusiasts. Maybe you could do a video on their 3000w Inverter/Charger with a 460ah battery and the 40amp dc to dc charger MPPT solar charger?
I will and others. I bought a litime trolling battery for a canoe setup. Do you know if a reliable and inexpensive lithium ion battery charger? just one that plugs into an ac outlet. Thank you!
Is the short-circuit protection on this battery reliable? I have not been able to find a video that tests this protection feature on any LiFePO4 battery. I'm wondering if I need to upgrade my cables to include an in-line fuse or if I can trust the short circuit protection. Please let me know if you have tested this feature!
I apologize if this has been answered somewhere but I'd like to know at what voltage the balancer on the BMS gets triggered? Is it at 3.45v or higher? Thanks.
got a response from the company through email. The voltage was higher than I expected. "When the cell voltage of the battery reaches 3.55V, and the voltage difference is more than 30mV, it will start to equalise."

No complaints so far
same here. After my AGM died / damaged I searched for a high-value 12v 100ah for my camper van and ended up with Li Time. Glad I did.
Cool update: How about a video about replacing the AC and DC distribution center for RV house with lithium battery ?
Most WfCO power centers are for lead acid batteries.
WFCO now sells a retrofit charger for their power center. I called a couple of days ago and for my Mo 8955 power center, the retrofit PN is 8955-AD-MBA. $105. Read the Amazon reviews.
If you are installing batteries in boats to go offshore, bluetooth is very useful. Being able to monitor the battery at cell level my head off any potential battery shut down in advance.
I have 3 litime batteries. I’ve just had one fail after only one year of little use. 100 size. I have contacted their customer service and will update on how they handle warranty.
Have you heard from them yet?
What did warranty department say
Pls. let us know. Warranty service is most important, even above overall battery design/build. Cells fail randomly.
Still going back and forth. Will update
I've seen this happening to a lot of people with these and customer service is trying to ignore them
One last comment , I forgot to add. Li Time allowed me to return my two questionable batteries. I will consider buying their product again. Very easy to work with.
Great info as always!! thanks
Great Video as always Will 😎 That Victron multi plus looks nice
Great stuff as always. Question / Content suggestion - for those of us who have older portable solar generators and are looking for additional capacity, can you come up with a way where we could interface a battery such as this one to the existing system? Perhaps where you could plug this battery in the solar generator 12v or 120 AC output to charge, and have a small inverter from this to plug the main system into to charge it. I hate to throw away the older, obsolescent, but still functional system until I've worn it out, which likely won't be for 5-10 years.
Hi Litime mini will always run my toaster up to 122 A. I thought it supposed to cut off at 100 A why is that ? it goes through my 2000 watt pure sine inverter. Shunt says 122 amp
I have a LiTime Mini and it seems perfect. It is a backup battery for my Trolling Motor.
Not too worried about the Bluetooth mounting. It is squeezed in place by the foam in a sealed box. Up down back and forth are it's only directions.
I just clicked on your link and these batteries are now $189.00
Amazing how the price comes down over time
I just got this from amazon it was $199 - $16 coupon - $20 promo code that brought it down to $164. Free fedex shipping. I'm using it to extend my powerstations (got an ecoflow, a jackery, and an vtoman) with buck converters 12-24v it plugs into their solar inputs. Works great. I bought litime's $79 20a charger with it. Thinking of getting another one. This gets kinda addictive.
Can you use a standard car battery charger to charge the 100 amp hour batteries the 12.8
Got a 50Ah Li time the other day, wanted a lighter battery for fishing kayak tolling motor. Got a led acid 77ah and i got the same range (or more i was done fishing) 1/3 of the weight and 1/2 the zise. Im happy
I picked up the 24v50a version for my Yak build. Great battery love the Bluetooth
Would you suggest another solution to monitor the battery if it doesn't have a Bluetooth module? Something that could display state of charge, voltage for example?
Yes a victron shunt
Our Vegas weather has been all over the place.
Looking forward to your new shop...
@2:43 the 291 A inrush is not almost the max of the Inverter (300 A *rated*). That is that inverter's max for the test condition (temperature, current slew rate, etc.). 3% low. I would expect an unpublished spec of +/- 5 to even 15% for a decent quality inverter. There is a tolerance at round that 300 A, an it is the 'max' so its nice that it tripped before it.
For your information: it donst realy need your location but the battery is using Bluetooth low energy, that was invented for indoor positioning - this is why the permission for BLE on android is called location pernission :D
Oh, that is useful to know. I wondered about that location permission :)
What do you think about lithium /bms disconnect vs diesel heaters? Diesel heaters are not so happy about brutal power loss.
Impressive, and the Bluetooth can save you from a walk in the weather if your batteries are in a separate power-shed.
I would love to see you take apart a bunch of 150Ah batteries for those of use that are limited to a group 31 space and are trying to maximize our usable battery capacity. So far I'm not finding many of the manufacturers that you even marginally recommend making them, but their size and capacity really interests me. It seems to me if a group 24 100Ah interests people a group 31 150Ah would appeal to an even larger audience...
👍or a 24v group 31, 75AH?
I like the Bluetooth feature for its state of charge feature. Without that you'd have to buy a battery monitor and wire it up externally.
Good finding the inside of both batteries all ways good saving money 🎉
Nice review. A real world test of the Li-time surge in will it start a car/boat several times. The conventional wisdom has been not to use LFP for such high surge loads, but it seems that the higher capability BMS’s might be able to change this. There is still the alternator charging challenge but that is a solvable problem for those of us with boat/RVs
It does say not to use it for starting purposes in the manual.
@@motofunk1 thanks.
Just wondering if you had two in parallel, could you use them to start a small diesel. I have a 9 hp single cylinder Volvo in my boat and wanted to switch to lifepo4 batteries.
The “don’t use lithium as a starter battery” has always been about temperature. Gets too hot in most engine bays to the point where degradation is significant in short periods of time.
A123 cells, cylindrical and pouch, have been used by some car manufacturers. You don’t need something with such crazy high C rate though. Your average prismatic cell can burst 3C-5C for a few seconds.
can you do a review on the new renogy 12V 200Ah Pro Deep Cycle Lithium Iron Phosphate Battery w/Bluetooth & Self-heating Function
BRO within minutes of you being impressed, i ordered 2 before the clip was over. They should pay u.
I went with the cheaper 12v 100Ah regular batteries, not the trolling motor ones. I live in the south so don't need low temp charging protection. I did add a Amped Outdoors smart shunt for $60. When using them for trolling batteries it's good to know your drain and SOC, especially if you are fishing a multi day tournament without the ability to fully charge between days. So, $80 to have it integrated isn't really a bad deal.
What’s different on the “trolling motor” version?
@@ChickFilA_Sauce low temp charging cutoff. That's it.
I have a Li Time mini. Can I use it with a trolling motor? Li Time says I can. Also- I charge it with a 5-amp 14.4-14.6 volt charger. My battery charges to 13.7 volt. It never reaches 14.4 volt. Is my battery bad? They said I could return the battery at my expense, but insist it is fully charged. Are the cells not balanced? and the cause of the problem.?
It will drop to 13.7V after absorption is reached. Very normal. Not an issue
My minis only go up to 13.8V with a 10A charger attached. So very likely that there is a balancing issue but I pulled 105Ah out of both so it’s not so bad that I’m missing out on capacity.
You probably have a similar balance issue. If one cell is hitting 3.75V and the rest are at 3.45V then you’re getting nearly 100% capacity from those 3 “low” cells. Might be missing out on 5%
Mahalo nice job testing these. I have been using Chins but they are resisting sending to Hawaii. Is shipping to Hawaii an issue with LiTime?
WILL!! Try to put it in an ICE vehicle and cold start it. That would be an epic test of over current protection.
Why can't you use TM batteries as car starter batteries? I would like to buy one , but as a car battery.
Apparently heat is the issue; if you can keep the battery around ambient it may work OK. I used those little motorcycle lifepo4 batteries (e.g. btl14a240c) as starters for my 2.3L sedan in SoCal (warm climate), but both the first and second one failed after about a year, possibly due to being run down or overcharged (the BMS was exceedingly primitive, appearing to only do balancing). The cells were all puffed out when I disassembled them.
Curious to see if the lift would work if you use a #10 gauge extension cord
His inverter can't handle the load.
great videos, i feel a lot more confident buying a battery now that you've opened so many of them up and can actually see the build quality and guts ... can you please post a link to the chargers you are using ? thanks !
With the surge amps getting up there I wonder if you could use that as a car battery.
@will, please test it starting a car...
@@SashiOnoor test running a Minn-Kota 27lb thrust behind a kayak.
The user manual says not to use it as a car starting battery. Warm temps and quick starting might work, but cold temps and hard-to-start draws more current for longer. No need to push the limits when a cheaper L/A battery is optimum for car starting purposes.
I really enjoy your channel. My son & I want to add a PV system to our sailboat. We are undecided about staying with 12v or into 24v someday we’d like change to an electric motor. Any advise?
id love a video on "solar array grounding". i noticed you havent covered grounding the array in a video, just inverter grounding. im curious if grounding the inverter using ac input also grounds your array thats plugged into the inverter but im doubtful.
I just ordered two litime trolling motor batteries look forward to trying them out on my boat lift and for trolling motor applications
How do we know these ultra cheap batteries really have grade a cells.
Also using an Ionic lithium diesel starter battery in my dump truck
Replaced three lead acid batteries
Starts the truck great charging with the stock alternator
Thanks for your channel
I’m struggling with my 24v system. I have two charge controllers for each solar array. It’s been working fine up until the other day, now the Bank one controller stays in Overcharge mode while the other Bank controller charges normally. I’m stumped!!
Great review.
For my simple trolling motor I have 12volt lithium battery with bluetooth app. Wouldn't be without it! There, I can always very easily see the SOC, and how long I can drive at different speeds before the battery is empty
Fantastic content bro!!!
Love the videos! Always so informative and unbiased.
Do you have any plans to tear down any of Monster Marine series of Lithiums?
Thanks!
I have a 50 HP Yamaha 4 Stroke Outboard with an alternator. The starter requires less than 285 CCA. I realize LiTime offers a 12v 20ah Start Battery with 650cca, but wouldn't a group 24 or 31 be a better battery in the long run? I plan to use 120v shore power to a Lithium charger keep it charged up. Is the issue the Outboard Alternator? My friend that works on RV's recommends that I use a group 31 led acid and not use Lithium LiFePO4 at all.
Do you have a video explaining how to charge lithium battery with a car alternator? How to limit current so alternator won't burn up?
Charge controller
Buy a DC to DC converter. I have the Renogy 40 amp DC-DC charge unit in my van. This is the one without the solar input. It charges a 300 amp hour lithium battery with 2000 watt inverter. It needs a separate wire to any car circuit that turns on when the key is on, otherwise it will drain the car starting battery with the engine off. My ignition sensing wire goes to the windshield wiper circuit, easily accessible. The DC-DC unit has another small terminal that will cut the charge output current in half when its energized. I installed a 3 way dashboard switch, up gives a full 40 amps charge, neutral is off, and down on the switch gives 20 amps to the lithium battery.
This comes in handy when the headlights are on, heater is on, and windshield wipers are going. At a stop light, all of this overloads my 105 amp alternator and the voltage drops to 11.5 volts. I switch to low charge, 20 amps, and the engine alternator will be at 12.8 volts at idle. Other Renogy DC-DC charge units come in 20/10 amp, 40/20 amp, and 60/30 amp sizes.
There are dip switches on the Renogy DC-DC charging unit to set battery type. The current into the lithium battery will reduce itself until the battery is at 100% charge. Then it cuts off charge current to the lithium battery automatically. I also have solar panels and opted to have a separate MPPT solar controller. The new combination DC-DC charge units don't put the full output to the battery. They share solar/alternator output. They also can't handle more than 24 volts solar input. My panels put out 96 volts. I hope this helps.
@@kimmer6 very helpful, thank you :)
Hello, I purchased the Mobile book, now the question, what is the max Watts I can produce for a mobile system and still run the campers 12 volt system? I am versed in electronics and avionics, but I'm not sure of the MPPT I will need and running 1680 watts @ 30 amps.
I like flush mount terminals like this one has! It makes cable routing and connecting so much easier compared to the to the style terminals that sit in a small recessed area of the case.
how do you connect the battery? mine doesn’t have a QR code nor does it come with bluetooth.
Thanks Will ! TAKE CARE..
Hey Will you need to do a 3000 watt inverter and the solar panel out put from Harbor freight 😊
My epever BN series button keeps tripping out on my 12v circuit but my 3K inverter is not affected, any ideas Will? The manual doesn’t mention when or why the button trips.
I’ve installed 2 group 24 batteries to replace my LED Acid on my 28ft RV. I fully charged them and tried using them. One of the two batteries will not show discharge and remains in standby according to the APP when 110 is disconnected. I’ve purchased a 3rd believing the battery BMS is bad but it’s still performing the same. Any suggestions as to what’s causing this?
Sorry I really can't find an answer for this battery. Will a mppt controller die if example this battery (BMS) cuts of power and the mppt controller still receiving solar energy?
In another video you are telling that, we always have to connect the batteries first, to avoid failure. But what if the battery just stops working? Will it then cause fire or destroy the controller?
I bought two of these to add more AHr to my Camp Trailer. As received, they came "charged" at 3.4 volts. That made no sense to me. Their email from their tech support response was fairly quick. I was told to charge them. I used a NOCO Genius 10 A charger. They seemed to charge but I found some discrepancies with the app and my voltmeter. I still want two Group 24 batteries.
Has anyone else found issues like mine? What is an alternate high-quality Group 24 battery. Bluetooth is not mandatory as I have a Victron Smart Shunt.
What about the Vatrer Group 24 w/ Bluetooth?
Heck yeah friends! 2 videos in 2 days 🎉🎉🎉🎉
No kidding! Seems like Will is out of ideas! Maybe he can start converting cars to electric or something like that with his knowledge. That will be very interesting... Or build up off-road car including the frame from ground up... Or electric ATV or something?
@@empower88 I'd love to see him wire up a system using auto salvage parts. My battery cables came from two crashed audis at the junkyard, I took the battery cables as they are high quality and long because the battery was located in the rear of the car.
Are there any bluetooth apps for this battery that have more visibility and control? The litime app works, but doesn't tell you much, or have the ability to graph long term data, change cut offs, etc.
Thank you Will! There aren't any lithium batteries that can be used in place of an engine starting batteries, correct? A lithium would need a kind of DC-to-DC smart charger in between the alternator, yeah? Thank you!
Cool video will thanks for sharing this six stars brother
@WillProwse i bought one of these after watching this video and researching a ton of other brands. Got it, and I have not used it much, and the Bluetooth module is having issue, doesn't report properly and "glitches"... no response from litime support. I have read that they are not very good at honoring their warranty... any ideas? Will the eventually honor their warranty? I have purched so recently i could likely file a claim with my credit card company in the worst case.
When running these batteries in series, do you need to worry about balancing them, or can you just charge them to full charge before hooking them up in series, and be good?
And if you do use a balancer, and I undestand balancing LiFePO4 batteries correctly, the balancer should not be left connected all the time, but only a couple times a year, or if batteries are drawn down to near empty? Talking about a trolling motor application, so the batteries will get a full charge after every use. Thank you!
@WillProwse Question: I have a stack of 6 EG4 batteries BMS communicating with my growatt 12K inverter. Theoretically, shouldn’t I be able to attach more LiFePo4 batteries in parallel without them being connected to the RS485 comms? I have found a different brand of rack mount batteries at a better price but they lack any wired comms. I understand the accuracy of the SoC may be affected but the internal BMS of the batteries control the flow of current and maintains safe conditions, correct? Buying matching batteries at the same time is always ideal but building on a budget is sometimes necessary. Thanks for your time!
Hello! Can I use this type of batteries connected in series? I want to connect in series for a disabled electric wheelchair? Is it suitable for something like this?
Haven't actually done it, but the manual includes diagrams for up to 4 in series and 4 groups of 4 in parallel for a total of 16 batteries. Says use identical batteries and there's some comments on balancing them before connection for 12-24 hours.
do they have a battery that can be used in a boat or car hooked up to alternator or solar panel in boat to keep it charged?
i just got 3 of these .. charged with noco genius for a bit .. BT came on .. app said each was about 50% charged. Powered them OFF so that I could wire them up in parallel in my trailer without sparks... now I can't figure out how to power them back ON... manual says just charge them, but my noco charger refuses to charge as it doesn't detect enough voltage .. because they are 'OFF' .. so scratching my head as to how to power these back on .. there is no on/off button :(
Did you try turning them back on with the app?
@@richardeverett1227 the app needs BT to be active, which it isn't .. as the batteries were 'powered OFF' ...
In the end, we managed to wake the batteries up with an 18v DeWalt battery and some wires... then all was good... BT came back on, app connected, inverter came on ... mppt came on ....
@@miramar-103 Good to know. I have a lot of lab power supplies that are current controlled, 0 to 4 amps, 0 to 30 volts so I guess I could wake up the bms fairly safely with one of those if it ever happened. I thought the BT would be active always even with the battery off, since it likely just uses a milliamp and would take a century to drain a 100ah battery.
Can this battery power a small microwave and or a coffee maker? Thanks.
Is there anything else required to put 4 of these in series to make a 48 v battery bank?
Would you recommend this battery for my teardrop camper?
What's the difference from this battery and the new trolling motor battery other than the size of the case?
All the specs are identical
I was thinking of getting 4 of these for a 48v Ryobi riding mower. Small yard and so thinking 50Ah. Any thoughts of doing 4 of these in parallel and pulling amps to run a mower?
Have you tested a Redodo 12V 100Ah? Someone said they are almost identical to LiTime 12V 100Ah.
I've heard from many sources that LiFePO batteries can be oriented in any direction. I just got 2 - 100aH batteries from Li Time, and the literature says to have them upright or contact them for other options. Upon contacting them, they said I could use them on their front but not on their back. Does anyone have an explanation.?
Can you make a video on the best way to charge a lithium battery solar setup with a car alternator?
I'm thinking about trying a 50 or 100ah litime for car subwoofer audio system build. Curious how well these would help
Thanks for the review … clear concise and factual. I was scared to buy a pair of 230 Ah Li Time batteries for $970, since it was 1/4 the price of battleborn (seemly the Cadillac of this category). Any thoughts on if this is a good plan?
how to fix battery not discharging
If I purchase a LiTime battery, can I incorporate it into a rack system that already has rack batteries?😮
Can these be mounted under my camper van without heating pads? Current setup is AGM batteries.
What about Eco worthy lifepo batteries?
Do you ever try them? I been running then on my home and been very happy , they run my home 95% with the rest of the solar system.
Nice job Will
Li Time makes a complete line of products for solar enthusiasts.
Maybe you could do a video on their 3000w Inverter/Charger with a 460ah battery and the 40amp dc to dc charger MPPT solar charger?
For some reason bluetooth perms on android always asks for location.
I will and others. I bought a litime trolling battery for a canoe setup. Do you know if a reliable and inexpensive lithium ion battery charger? just one that plugs into an ac outlet. Thank you!
I have 2 chargers, a 10a and a 20a. Can you really use both at the same time and get 30a charging?
Is the short-circuit protection on this battery reliable? I have not been able to find a video that tests this protection feature on any LiFePO4 battery. I'm wondering if I need to upgrade my cables to include an in-line fuse or if I can trust the short circuit protection. Please let me know if you have tested this feature!
Great Review Thxs!!!
If you don't have Bluetooth, how can you know the state of charge? Seems like having no fuel gauge.
I have a guest charger lead acid/gel. It charges to 14.6 I think. Will this charge lithium batteries?
I apologize if this has been answered somewhere but I'd like to know at what voltage the balancer on the BMS gets triggered? Is it at 3.45v or higher? Thanks.
got a response from the company through email. The voltage was higher than I expected.
"When the cell voltage of the battery reaches 3.55V, and the voltage difference is more than 30mV, it will start to equalise."
