Description
JK SMART ACTIVE BALANCER 24S 4A – Model: JK-B4A24S (BE59)
The JK Smart Active Balancer 24S 4A (JK-B4A24S BE59) is a high-performance 4A active balancing module designed to optimize large lithium battery packs up to 24 series cells. With powerful bidirectional energy transfer, it redistributes energy between high and low cells with exceptional speed and precision—far more effective than passive balancing.
This balancer supports multiple chemistries including LiFePO4 (LFP), Li-ion (NMC/NCA), and LTO, making it ideal for a wide range of custom and professional battery systems. With Bluetooth monitoring, users can view real-time balancing activity, cell voltage data, statistics, and fault logs directly from their smartphone.
Perfect for 24S high-capacity batteries used in solar power storage, electric vehicles, high-power inverters, and industrial systems.
