JIKONG JK-B1A8S20P Smart Active Balance BMS 200A | 4S 5S 6S 7S 8S 12V/24V for LiFePO4 Li-ion LTO Battery

JIKONG 8S Series Active Balancing BMS – 1A/2A Balancer 200A for LiFePO4

The JIKONG 8S series is a smart Battery Management System with active balancing (non-lossy balancing) technology, designed for 4S–8S 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 1A or 2A balancing current and 200A continuous current. Select models include heating (H) and CAN communication (C) for advanced system integration.

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 1A–2A) without affecting cooling. It is more suitable for larger capacity battery packs due to longer balancing times and higher currents.
