HQST 12V 300Ah (330Ah) Mini LiFePO4 Battery, 3840Wh, 200A BMS, Grade-A Cell | Deep-Cycle Lithium Battery with Low Temp Protection, Series/Parallel, for RV, Marine, Trolling Motor, Solar & Off Grid
A 12 V 300 Ah (3,840 Wh) compact battery with a 200 A continuous rating, rated for 8,000 cycles to 70% of original capacity and expandable in 4P4S. Its 200 A discharge matches most 300 Ah batteries listed, though a few models rate 300 A. The cycle rating uses a shallower depth than the 100% figures many rivals give, so it suits RV, marine and solar users wanting a smaller 300 Ah case.
