12V 100Ah

After fully charged, I tested by Xantrex 3kw DC-AC inverter and a 1kw water heater for 3hrs and 15minutes @118v@8A@1kw, the battery is still constantly output the power after consumpted 3kwh. Time will tell longevity. I camped on snow mtn for 2 nights last week, battery discharged over 240Ah with no issue. I scaled battery weighs only 57.5lbs, possibly the lightest lifepo4 battery with real 300Ah in market. second one had been delivered. I parallelled the 2 together. The first one came without manual but seller emailed me after I asked. Seller responded fast about questions. I am very satisfied with the capacity and steady performance of the battery. Will buy the 3rd one now. The M8 bolt is useless because it is too short, not issue for me coz I can use old bolts. For such competitive price with excellent capacity, ignore the bolt.The 3rd battery delivered 10 days ago and I have parallelled 3 batteries. 900AH could last at least 2-3nights with 80watts heating blanket, and a water heater, microwave oven during snow camping. I am happy that my battery bank got upgraded. Sad thing is, I have to upgrade the inverter and system control panel. Extra money has to spend to protect the lifepo4 batteries.

First, a couple of thoughts. Lithium batteries that have the same amp hour rating as a lead acid battery actually deliver twice the time in use that a lead acid battery does. Also, a golf cart draws either 56 or 75 amps, depending on whether it is 48 or 36 volt. So, a lead acid battery with a 100 AH rating will run a 56 Amp (48 volt) golf cart for about 50 minutes. A 100 AH Lithium battery will run the same golf cart 100 minutes. The reason is lead acid voltage drops as the current is drawn while a Lithium stays at pretty much a constant voltage. So, if you hook the batteries up correctly to get your 48 volts ( 4 batteries connected in series which means positive to negative to positive to negative to positive to negative, everything will work just fine. In my case, I was powering up a motorhome. What I had before was 8 100AH lead acid batteries connected in parallel which provided me with 800AH or 400 AH of usable battery. I replaced that with two 300 AH Lithium batteries which took up less space, weighs considerably less and yet gave me 600 AH of usable power instead of the 400 that I had before!! I have now used it several times boondocking and they work great. I have a 4000 Watt pure sine wave inverter so I can run the entire motorhome for several days without having to run the generator. Nice!!!! I had to change my older charge controller which does not allow for no float voltage that a Lithium battery uses, but after that, all I had to do was set the controller for lithium batteries and the charge is taken care of. If you have a newer rig, you should already have that setting available. Check with your charge controller manufacturer if you are not sure. The batteries work perfectly and I am very happy with them. I would highly recommend them. The manufacturer has a ways to go getting relevant information out on charge requirements, but that is all easily available from general web sites covering Lithium batteries.

The best price I’ve found for similar batteries. But there are a few substandard batteries mixed in with batteries that perform perfectly. You’ll need to identify the bad performing batteries quickly in order to exchange them. Customer service is pretty good, very responsive. The ones that work are every bit as good as similar batteries that sell for several hundred dollars more per unit. So, it’s worth sorting out the duds - just be sure to do it quickly. Run a capacity test at a minimum, and a self-discharge rate test if you have time. If any of them behave “strangely” along their charge-discharge curves, exchange those batteries immediately. The value for the money on the ones that work perfectly is very difficult to beat.

I got 2 of these to build an inexpensive 24v 100ah battery bank. I did nearly everything you are not supposed to do except try to charge them below freezing. I didn't activate the BMS before I assembled my battery bank. The batteries were not balanced close enough. I didn't realize that my charge controller would not support a 24v LiFePO4 battery bank (when I bought it the advertising said that it did. I noticed those claims have been removed) so I had to get a new charge controller. The batteries were not discharging right. I had a huge power drop twice. I was afraid that I had wrecked these batteries but that didn't happen. I took everything apart. Charged the batteries independently. Contacted JITA-US and got the advice I needed to put my battery bank together right. Everything is working well now. I use this PowerStation to run some stuff around the house and in the yard. I live just south of Lake Erie in PA so December is not the best time to do a battery project. I find that these batteries accept power readily and hold well after peak sun. So far, they are working really well. I look forward to updating this next year. 16 month update. You should buy this battery! You can build a 5.12kw battery bank for under $1300 delivered! The manual says you can Parallel 2 sets of these to build a 10kw battery bank for $2600. No rack mount communication cables. I beat these batteries up when I first got them but since I got the battery bank properly assembled not a single problem in 16 months.
