12V 100Ah BCI Group 24 Lithium Battery, Rechargeable LiFePO4 Battery with Up to 15000 Cycles, 1.28kWh and Higher Energy Density, Perfect for Van, Trailer, RVs, MotorHome and Boat Scenarios.

2 x wired in series to 24v Ultrex, on 19' Bass boat. Out of the box, 1st battery had 13.2v, 2nd had 13.15. Utilizing a NOCO gen 4 in lithium mode, 1st battery fully charged in 20 mins, 2nd took 5 hours. Fished 8 hours for crappie on brush piles, in high winds, minimal motoring,using spot lock with no issues. Once back on land, batteries too 1 hour to fully charge. 2nd trip out bass fished in high winds, running trolling motor at 5/6 for majority of day with no issues. Back at the camp, batteries fully charged in 30mins. So far, I love them. Weight savings is great. The price can't be beat.

Update: LiTime has refunded the cost of the battery and provided a FedEx return shipping label. I ordered another battery from them and it has worked flawlessly, it’s a huge upgrade from the traditional lead acid battery that was in my travel trailer. Unboxed this battery and followed the instructions to “wake up” battery. Promptly placed it in my RV and connected the solar charger to it after making sure that the Lifepo4 setting was chosen. After a day the battery is only showing 9 volts. Unhooked it and brought inside, placed it on a lower amperage Lifepo4 charger in and that charger says battery is bad. Did wake up procedure again (and again and again) but still will not accept charge. I am 100% sure that the BMS controller of the battery is malfunctioning or the cells are improperly balanced straight out of the box. I’ve sent a message to the seller but have not heard back yet. Will update as to how this is handled.

Twice the usage of the pervious lead acid battery for the camper.

I have been using two of these to power my trolling motor for 11 months now in my Bass boat with zero issues. Great batteries, great price.

After doing a lot of research I purchased the 12.8V 100AH. My intended use was for a CPAP running through a 500W pure sine inverter. I charged the battery fully and it stopped and maintained a charge of 13.36. I used the CPAP for 7 hours and retested the battery with a volt meter with a result of 13.32 battery charge! I couldn't believe how little power the CPAP used. Amazing. It should be noted I did not use the humidifier feature on the CPAP during those 7 hours. Very happy with this battery.
