ExpertPower 24V 10Ah Lithium LiFePO4 Deep Cycle Rechargeable Battery | 2500-7000 Life Cycles & 10-Year Lifetime | Built-in BMS | Scooter, RV, Solar, Marine, Overland, Off-Grid

I converted from 12v to 24v for my refrigerator after noticing heating in the power cord plug. This addressed the heating issue. Also, the battery was a third the price of my 12v five years ago.

I have 2 in Parallel 24v 200amp, difference in voltage with both batteries charged separately is never more than .01-.02v difference, I periodically charge them separately to see the watts need to fill, never more than 500 watts difference and that's on different dedicated Victron charges so it may be closer. I have built more confidence in the product over about 50 charges and now charge them in parallel with only random checks for health and balancing charging separately. I do not constant or daily charge, I allow the batteries to discharge too 30-40% remaining than top them off. I also allow the Victron to be conservative on the voltage never pushing them to the full rated voltage. I charge them at 36amps for the set or 18 amps each if by shore power and 20 amps in parallel for solar. By all the research I have read The settings should give me 2500 charge cycles or moreRunning 4 Engel refrigerators/freezers at 24v and a small microwave on a Victron inverter I get 3-4 days on a solid 100%charge. Only time will tell, but 6 months in no issues whatsoever. I did email them and ask for a matched set and both batteries are labeled same month and were less than 6 months old when they arrived. Shipping was fast from them, Amazon does not ship this item, Expert power handles all there own.

Used once will not charge up.

I used it up on my trolling motor for 8 hours straight. My battery indicator showed that still have 3/4's of the charge yet. Can't ask for a battery unit better than that. Never would come back for the traditional battery again that you have to recharge it again and again. Awesome battery.

I needed this for an AC unit. They shipped it across the country in two days. These guys are fantastic. Buy from them

Unfortunately this battery didn't work for my application. Also, these are difficult to test and diagnose due to complexity of built in electronics.

Didn’t work. I thought maybe even it came dead but I tried to charge it with the correct battery charger and it didn’t work.

Battery worked fine for about 8 months...then would not take a charge..contacted support and they would not honor warranty...
