This is a 12V 300Ah lithium iron phosphate (LiFePO4) battery with 3,840Wh of energy capacity. It uses EV-grade prismatic LiFePO4 cells in an ABS housing. It is used for RVs, marine setups, off-grid cabins, home energy storage, solar systems and emergency backup.
A 200A battery management system (BMS) protects against overcharge, over-discharge, over-current, overheating and short circuits. The cells are rated for 4,000+ cycles at 100% depth of discharge and a lifespan of over 10 years. It can replace three 12V 100Ah lead-acid batteries and is 2/3 lighter than lead-acid.
Up to 4 batteries can be connected in parallel and 4 in series (4P4S), for a system of up to 51.2V 1200Ah. It can be charged with a battery charger, solar panel, generator or alternator. It is not a starter battery. Do not mount it with the top or front side facing down. Other orientations are fine.
