TOPLi 12V 300Ah Lithium Battery

Regular price $1,700.00

TopLi-12-300 is a 12V 300Ah lithium deep cycle battery. This lithium iron phosphate (LiFePO4) battery is ready to replace your heavy lead-acid battery bank in your sailboat, RV, or solar energy system. It’s only 27KG for a true 300 Amp Hour lithium battery that provides 100% of its rated capacity. The TOPLI-12-300 gives you the flexibility to replace several small, heavier lead-acid batteries in a single high-capacity unit.

LiFePO4 batteries are lighter, take less space, and last longer. While the up-front cost is higher than Gel, AGM, or Lead-Acid the overall cost of ownership is lower over time because they require no maintenance and they have up to 10x longer life.

The TopLi-12-300 offers high, reliable performance in any climate or condition for RVs, campers, sailboats, and battery-based solar systems.

All TOPLI-12-300 Batteries use the safest and most stable components, including 4X A class prismatic LiFePO4 cells and a built-in Battery Management System (BMS). The BMS ensures a long lifetime, good performance battery.
