JIKONG JK-B1A8S20P – 1A Balancer 200A BMS for 4-8S LiFePO4

JIKONG JK-B1A8S20P – 1A Active Balancing BMS for 8S LiFePO4

The JIKONG JK-B1A8S20P is a smart Battery Management System with active balancing (non-lossy balancing) technology. 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.

Because active balancing generates almost no heat, it can use larger balancing currents (up to 1A here) without affecting cooling. This makes it suitable for larger capacity battery packs.

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