JIKONG BD Series 20S/24S Active Balancing BMS – 0.6A Balancer 40A-150A for LiFePO4

The JIKONG PD series is a smart Battery Management System with active balancing (non-lossy balancing) technology, designed for 20S or 24S LiFePO4 battery packs. It transfers energy from higher-voltage cells to lower-voltage cells, achieving voltage balance with minimal energy loss. It operates continuously during charging, discharging, or idle states until the voltage difference is within the set range.

All models feature 0.6A balancing current, screw terminals, and no GPS port. Available continuous current ratings range from 40A to 150A.

What is Active Balancing?

Active balancing transfers energy from cells with higher energy to those with lower energy, achieving voltage balance with minimal energy loss. It operates continuously regardless of charging, discharging, or idle states, until the voltage difference is within a set range. Since it involves energy transfer without heat generation, active balancing can use larger currents (commonly 0.4A–2A) without affecting cooling. It is more suitable for larger capacity battery packs due to longer balancing times and higher currents.
