Power heavy-duty systems with ease. The Power Queen 12V 300Ah LiFePO₄ Battery is a game-changing alternative to bulky, short-lived AGM batteries. Delivering 3840Wh of energy and weighing 85% less than three 200Ah lead-acid units, it’s ideal for solar homes, RVs, boats, and off-grid cabins where every kilogram and cubic centimeter matters.
Compared to three 100Ah lithium batteries wired in parallel, this single unit offers greater performance, reduced wiring, improved system efficiency, and fewer connection points — all while saving space and setup time.
Equipped with an advanced 200A BMS, it delivers 2560W of continuous output and handles peak loads up to 800A for 1 second, making it suitable for high-demand devices like inverters, power tools, and multiple appliances running simultaneously. The system is expandable up to 61.44kWh via 4P4S configurations.
With up to 15,000 cycles, a 10-year service life, IP65 dust/water protection, and top-tier certifications, this battery offers high reliability, long-term savings, and peace of mind on every adventure.
