6Ah 12V Lithium LiFePO4 Battery 6Ah Lithium Iron Phosphate Battery, Deep Cycle Rechargeable Battery, Perfect for Lamp, Scooters, Children Toys

This little battery packs a surprising punch. It's been perfect for powering my portable lights and some smaller electronics. Lightweight design and the built-in protection system give me peace of mind. Good value for the price.

Pros:- Measured capacity of 6.04AH- BMS tested to work for over voltage, under voltage and over current- Lightweight at 1.563 lbsCons:- Arrived with 20% charge- Cells are out of balanceBattery voltage as received was 13.03V. This is very low. Charging at 2 amps, the battery took 4.850 AH of capacity and disconnected at 14.1V. So the battery was indeed low at 20% charge.I then discharged the battery with a 2A load until the BMS tripped for low voltage. Doing so, the measured a capacity of the battery was 6.036 AH. (see photo) This battery meets the manufacturers spec.Battery was then recharged, and took 6.045 AH and disconnect happened at 13.9V. The disconnect voltage is low which means the internal batteries are out of balance.Over current testing was then performed and I found the BMS would disconnect in less than a second at 25A.Summary: Battery delivers on capacity. BMS checks out okay. Low disconnect voltage during charging suggests cells are out of balance.

6Ah in a little lightweight cube. Far superior to lead acid battery in terms of weight, footprint, lifespan charge and discharge cycles. Take this battery, a solar panel a charge controller and maybe an inverter to keep all your electronic toys charged while out on the go indefinitely.

6AH model is rated for 3A continuous, 6A max (1C just like their big 100AH brothers).
