Polinovel BL Series lithium battery is the direct replacement of deep cycle lead-acid batteries. It uses automotive-grade EVE LiFePO4 cells with low internal resistance, high consistency and sufficient capacity. In addition, the battery has been enhanced with cutting-edge process technology to ensure reliable and efficient operation. Advanced laser welding process is used to ensure stable high power output.

A unique protection mode is available to easily cut off battery discharge. What’s more, there are wireless software upgrade to help troubleshoot battery issues, and calibration function to directly calibrate current and SOC without extra tools.

This LiFePO4 battery has IP67 waterproof resistance and exceptional shock resistance. It is the ideal solution for marine boats, RV motorhomes, and other applications exposed to wet conditions or rough vibrations.

To guarantee its reliability, Polinovel has conducted rigorous tests. Our battery has been submerged in 1-meter deep water for 30 minutes, and dropped from 1.7-meter stairs for 10 times. After the tests, the battery maintained normal voltage and a stable Bluetooth connection.
