Battery BullTron LiFePO4 - 12V / 750 Ah - Polar

750Ah BullTron Underseat Polar | Maximum power in a compact design

750Ah LiFePO4 12.8V Polar battery with smart dual BMS, Bluetooth app, 5A active balancer, and heating element.
Suitable for use in temperatures from -30°C to 60°C.

Safest Lithium Technology (LiFePO4)

BullTron batteries utilize lithium iron phosphate (LiFePO4) technology, currently the safest lithium technology on the market.
All batteries consist of high-performance and highly durable LiFePO4 cells and an integrated Battery Management System (BMS).
The BMS continuously protects individual cells and the entire battery from over/undervoltage, over/undertemperature, overload, and short circuits.
The BMS effectively prevents premature battery failure due to external influences or improper use.
Another advantage is a weight reduction of up to 80% compared to conventional batteries of the same design and capacity.
