Glad to know they are highly repairable, thanks for the video!
What is repairable? Replace one cell of four? :)
Awesome to see what's inside. Some still shots of components would be nice to see.
I bought 2 for my motorhome. I replaced my charger converter to a lithium model to fully charge the batteries. I then spent the night in my motorhome to see how the batteries would do. The batteries powered the furnace fan all night long. Then I ran electric space heater off the batteries until they were low but not dead. These batteries lasted much longer than the lead acid batteries would of lasted. I'm impressed with the power so far. Bluetooth works. The app works but is a little slow, and requires a refresh at times. Otherwise works well. I would purchase these batteries again, especially if they increase the amp hour capacity.
James, glad they're working well for you. And thanks for the review on the website! With that charger, they should give you many years of use. Thanks again and stay safe.
I sat here nearly in tears watching you do open heart surgery on the poor battery...if the poor thing is up for adoption please duck tape it together and send it to a loving home 😭
I gotta pull 2 12v 200AH batteries apart to reconfigure them to 48v with a new BMS, assuming each battery pack is paralleled internally. I was using them in a 24v config but one didn't fully charge and cut off while the other had 40% left.
I think i might use a oscilating cutter tool though.
Addendum to the below comment. Oh well.. good to see the nice VICTRON inverter in the background. Great choice.
120920/0648h PST- 1448 UTC. Thank you for tear down of the LiFePo4 battery bank and exposing the cells. The JBD BMS controlling the balance and temperature cutoff is a very reliable device. I’m sure many DIY circle would prefer assembling the same by themselves, thus saving immense amount of funds. I’d prefer doing that, myself.
Thank you for the presentation. Hmmmmm lot of muscle power, indeed. Well, Sir, take care n stay safe. 73s...
Some people do like saving money. For an all-in-one LFP battery solution though, we feel we're a pretty affordable choice. Thanks for the comment and good luck!
Nice Review but please, get a dremel to cut the battery
Good teardown job A+👍
Really doesn't matter what kind of insulation use on The Wire if it was wrapped with pure virgin Angel hairs it wouldn't increase the amp capacity of the copper wire. The silicone insulation would be good in case of short circuit fires. The more insulation the more heat the wire retains leading to lower amp capacity. I question that 8 gauge wire on a 100 amp capacity test. You should show us with the battery taking apart discharge and charging and see how hot the wires get
William, here's a video testing 115 amps across the wire.
th-cam.com/video/iRH9sRL1_uY/w-d-xo.html
I completely agree that the insulation isn't an alternative to properly sized wire, but in this case 8 gauge wire is enough for a 12 volt 200 amp draw. The main thing to consider is the wire is only inches long, if this were 10 feet you'd want 0 gauge wire.
Excellent video!
Do you have a video of a breakdown on a 48v lifepower4 100ah battery?
Thanks for the dangerous unboxing battery pack👍👍👍😘
I was hoping to see the important part. The construction type of the cells. You only unboxed it.
Same here!
Looks like a nice battery where do they ship grom
Thank you 👍
Whats the actual name of that wire you say handles a bunch of amps?
When will these be available again?
What is the max supported current for 5 or 10 seconds? Did you test and verify it? Thanks.
Wish I had heard of you guys sooner.
Danke!
Thanks Clear and thorough review
Thank you for your posting ❤️
it was a very nice video👍
But why two negative cables?
GOOD VID eco worthy has them for half the price
Put it back together!
What is the volts of one cell
Thanks for this tear down video. I have two questions. 1. How do you fix this type of battery at your shop ? Is there any advantage/disadvantage of this battery vs the metal case one ? Thanks for your time.
looks inside exact to a chins, ampere time and recently zooms minus bt
They do appear similar in form. The difference is in the cell quality (Grade A vs B), wire gauge, connection quality, and of course, we put a quality BlueTooth BMS in everything over 50AH.
Where is the battery made?
Almost all battery cells are made in China, the rest are mostly S. Korea and Japan. Ours come from China.
Where 99% of everything is made...China, Vietnam, India, Korea or Mexico. Gotta love great ole greedy USA.
Nice video. Keep safe.
I see the positive going directly to the cells but the negative is fed through the BMS first. How can the BMS circuit board handle the CCA going through the negative? Or does it not work like that?
That’s how they work and are designed to be set up.
looks so good!
Stands don't impact how much battery amperage the line can carry.
Not individually, but the finer the strand, the less space is between them, making a denser cable and increasing capacity.
Great skill with that hand saw! I would've been opened up faster than that battery 😅
Definitely sounds like your one of those guys lol
Nice tear down. Do you guys ship to Canada ?
Did you count the strands of the 8 gauge wire, lol. Going to be picking up a couple for my boat.
This is one where I think we'll just push the "I believe" button! :)
Is the temp sensor a High AND Low CHARGE disconnect based on ambient? I don't believe you said anything about what it's for or how it works.
Yes, it disconnects if it goes outside of a temperature range. See datasheet on the downloads tab at our website for battery specific values.
Can we remove the BMS and use/charge directly? I have a good battery with a bad BMS.
This is never recommended. The BMS is your first line of defense from overcharging or charging while freezing, too many volts/amps, etc... which all can cause bad things to happen. Do you have a reBel Battery? If so, get in touch via support@rebelbatteries.com and we can work out something through a warranty claim.
@@reBelBatteries no, I don’t have a rebel. I wound up replacing my BMS and am now very happy. The BMS was super easy..Thanks for the advice!
My 12v 100ah battery shut off what can I do to restart the BMS?
Send an email describing the problem to support@rebelbatteries.com. Include battery type, size, and any important information that may help troubleshoot the problem.
What national or international organization(s) rate #8 wire as you have listed. Don't believe NFPA rates it at 200 or more amps. Does NEMA or a similar recognized organization approve of those ratings? I can't tell the origin of the charts you showed. Also question the BMS being directly fastened to the cells. I know some manufactures do this but most of the better companies provide some thermal insulation between the BMS and the cells to minimize cell deterioration from heat.
Enjoyed the video otherwise. Thanks.
I was trying to replace my Electric ATV's 1500w 48v (4x12v20Ah lead acid) battery and I was wondering what LiFeP04 battery you could recommend to replace my old acid battery. Any help would be greatly appreciated.
you can use 4 units of that kind of battery on this video.
just don't forget to set up the proper BMS for battery safety and healthy.
in this video, it's 100 Ah battery set, 12 Volts.
you need that 4 units battery, so you will have power of 48 Volts and 100 Ah if you connected in series (not paralel).
the more Ah of battery you set, will give you more range (mileage) of your electric motor.
the more Volts of the battery, will produce more power of your electric motor.
the choice is your... wanna get more power or more range... or... both...
👌🏼🔋⚡
Thank you for interesting video.
, I am going to replace Acid Aux battery for my motorhome for12V 100Ah Lifepo4 Lithium Iron Phosphate Battery Built-in BMS . I have question for you, can I use motor alternator to charge battery during the ride ? Is the BMS will be automatically off charging when battery is full
Yes, you can certainly do that. However, the battery will suck up 100% available power from the alternator (100 amps) if it can supply that much. For most alternators, that means you'll run it very hot and probably kill it within a short period. I've seen some good videos of charging from the alternator through a DC-DC converter, that converter can regulate how many amps are being pulled off the alternator so as not to kill it. Search for "charging LiFePO4 with alternator" and you'll find some good info. Tito has a good one I watched last week. (th-cam.com/video/TDxfRXgQT04/w-d-xo.html)
Oh, and yes, once the battery hits it's High-Voltage Cut-off, the BMS will stop pulling power from the alternator or converter (if you go that route(recommended)).
@@reBelBatteries Thank you for detail explanations
Can these batteries be put in series and parallel? Is this battery approved by ABYC Thank you
Yes, they can be put in series and parallel. ABYC 13 (Lithium on vessels) is not final upon last check, but it looked like our batteries meet the spec. If there is an approval process, we are unaware of it.
@@reBelBatteriesis shipping free in
USA
Gotta know your own product if your going to review your own product!
Csn these be used on trolling motors , I know some say deep cycle and some don't!
They're great for trolling motors. Anything pulling less than 100Amps @ 12V.
Should have a review for you soon ! Just ordered one to give my Dad for Christmas 🎄. Thanks
@@dustinsmith9204 Awesome, I'll be looking for it. Ships today via UPS. You should have it in plenty of time. Thanks!
@@reBelBatteries -- This looks like a very well-built battery at an attractive price point. Can they be safely connected in series to power a 24v trolling motor? Also, can they be safely charged using an on-board AGM dual-bank charger, or do they need a special lithium charger? If so, do you sell those?
@@jasonbroom7147 We are sold out at the moment. These did not have the parallel capability, but our next batch will and would be perfect for a 24v trolling motor. Stay tuned! Delivery in mid-February.
Does the BMS has cold temp charge shut off?
Yes, our batteries have low and high temp cutoff. Adjustable through the Bluetooth app if needed.
You sell these batteries? If so... do you build them yourself? Even if you don’t... still very impressive. Fantastic job tearing that thing down.
Also... there is another TH-cam channel called SV Seeker. It’s a guy building a huge sailboat in his yard. Yeah sounds crazy but it’s awesome. He has a lot of subscribers. Just came to mind that I’ve seen him talking about needing batteries in some of his vids. Idk if he still needs batteries for the ship but he might. Could be a fantastic way to drum up,business if you do like a collaborative thing with him. I have no idea what kind of batteries he needs tho. I’m sure they could probably make just about anything work but Idk anything about batteries or battery banks aboard vessels. Lol. Just thought I’d mention that to you. Cheers
No, I don't build them. We work with our manufacturer on specs and then import in bulk. Thanks for the positive feedback, it was a lot of fun cutting it open! Fun fact, I had asked the manufacturer to leave one battery unsealed, but word didn't make it down to the manufacturing line. :) So I busted out the hand saw!
@@reBelBatteries thank you very much for the reply 🙏
@@reBelBatteries honestly... using a hand saw on a battery would be a bit nerve wracking for me. 😂 you’re a brave person
@@TsunauticusIV This was actually my second time, I cut open the sample we received two months earlier, just went nice and slow on that one.
Thanks for the video. What are the thoughts on adding batteries from a different manufacturer to an existing setup? I have 2 Lion Energy 12V 100ah that are about 6 months old. Haven’t really been used since I’ve been on shore power all the time except for when moving down the road (2-3 short trips).
The old advice for lead-acid was don't mix due to changes in charge efficiency over time. However, LiFePO4 batteries don't suffer those changes and can be mixed if the BMS's are designed for whichever way you plan to use (parallel/series).
Our batteries (100/200/300) can handle either of these configurations. Not sure about the Lion batteries, I would think they can, but definitely check up on it for your model number.
Some various opinions:

@@reBelBatteries Thx. The Lions do support all configurations. I’m paralleling (currently 12v/200ah). Thx for link to other info.
👍🏼👍🏼
Great review.What is BMS name?
JiaBaida SP04S020, but all incoming batteries will have the newer SP04S028 Model.
Disassemble the battery pack
Put the brand in the title please.
Forgot that on this vid. Done, thanks for the heads up!
Are the cells made in the US ?
Jimmy, there are no US-based cell manufacturers that I'm aware of. Some battery sellers state (designed and assembled in the USA) but the cells still come from overseas.
@@reBelBatteries Thanks. Everything is made in China nowadays.
There are some small scale manufactures in the US (see link below), they are like specialized cottage industries in comparison to the manufactures in China, Korea and Japan. The Chinese and Koreans can produce excellent quality stuff at attractive prices. The US has pretty much missed the boat when it comes to manufacturing lithium cells.
usamadeproducts.biz/electronics-batteries-lithium-ion-batteries.html
@@urbanimage yeah, the USA doesn’t miss the boat when it comes to executive salaries/benefits and withdrawing their stock dividends. Got it nailed in good ole greedy US of A!
open the cells
its not for starting a car, that 8mm kabel fry
The LiFePO4 chemistry electrical storage cell is not designed for fast high current drain, as in starting an engine. However, if paralleled with some big Super Capacitors, you can do it, because the power comes from the Caps, and the LiFePO4 battery only charges the Caps from a small gauge wire.
Why there is no cell compression?
@@reBelBatteries In the DIY battery building scene people are discussing cell compression intensely:
th-cam.com/video/FdDy8b5x7Y8/w-d-xo.html
Most of them compress their batteries to maximise cycle life.
I wonder why drop in batteries often have no compression. Do those manufacturers simply not care about reduced battery life?
Being confused about that, I decided for myself to go for a battery with cylindrical cells. Cylindrical cells do not need compression by their geometrical design.
Look like Prismatic cells.
U meant 1C
Also, BMS details. Big deal about the cable. Purely an unboxing. Nothing to see here, folks.
volume too low
