JKBMS 150-200A BMS LiFePO₄ Battery Protection Board

JIKONG 20S/24S Active Balancing BMS Series – 0.6A–2A Balancer 150A–200A for LiFePO4

The JIKONG 20S/24S series is a smart Battery Management System with active balancing (non-lossy balancing) technology, designed for 20S or 24S LiFePO4, Li-ion, and LTO 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.

Available with 0.6A to 2A balancing current and 150A to 200A continuous current. Optional universal display screens are available in 2.3-inch, 3.2-inch, and 4.3-inch sizes.

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.
