Polinovel DUAL Series is high-performance dual purpose lithium battery that offers a strong surge of power for starting and has a remarkable continuous discharge rate for a constant and steady power supply.

Our DUAL Series lithium battery uses top-grade EVE LiFePO4 battery cells with long cycle life, low internal resistance, and good consistency. The cells are connected by advanced laser welding technology, to handle high currents and guarantee long-term reliability.

A unique protection on/off mode is available to remotely cut off battery discharge, ensuring enhanced safety. Wireless software upgrade is offered to troubleshoot battery issue. And there are current calibration and SOC calibration to ensure accurate readings. If the displayed current or SOC deviates from the actual value, you can easily calibrate them within the app without using extra tools.

This LiFePO4 dual purpose battery has IP67 waterproof resistance and exceptional shock resistance to withstand even the harshest conditions.

To ensure 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 10 times. After these tests, the battery maintained a normal voltage and stable Bluetooth connection.
