A 12V 300Ah lithium iron phosphate battery rated at 3840Wh, built with Grade-A prismatic cells and a 200A smart BMS. It is aimed at trolling motors, RVs, solar banks and kayak fishing setups. The 200A BMS is the headline figure: it lets the pack feed a large trolling motor or inverter without tripping, where many 300Ah lithium batteries cap their BMS at 100A to 150A. DJLBERMPW is a small, low-profile brand, so the long-term support and real-world cycle life are less proven than with Battle Born, Renogy or LiTime.

This is a 12V 300Ah lithium iron phosphate (LiFePO4) battery for marine and other deep-cycle uses. It stores 3840Wh of energy and uses Grade-A prismatic cells in an ABS+PC shell.
A built-in 200A smart BMS protects the battery. The cycle life is 4000 to 15000 cycles, with a 10-year lifespan. Multiple batteries can be connected to expand the system in up to 4P, 4S or 4P4S configurations.
It suits uses such as RVs, trolling motors, kayak fishing and solar systems. Charge it only with a charger designed for LiFePO4 batteries, not one made for conventional lead-acid batteries. Do not immerse it in water for a long time.
