Description
JK SMART ACTIVE BALANCER 24S 15A – Model: JK-B15A24S (BE5B)
The JK Smart Active Balancer 24S 15A (JK-B15A24S BE5B) is one of the most powerful active balancers available for large lithium battery packs. Designed for 1–24 series cells, this unit delivers an incredible 15A active balancing current, making it ideal for very large-capacity batteries (200Ah–2000Ah+) where rapid equalization is essential.
This professional-grade balancer improves performance and lifespan by redistributing energy between high and low cells at extremely high speed. Equipped with Bluetooth connectivity, users can track cell voltages, balancing current, temperature, and status from the JK mobile app.
Suitable for all major lithium chemistries — LiFePO4 (LFP), Li-ion (NMC/NCA), and LTO — this unit is perfect for EV battery packs, large solar battery banks, and industrial energy storage systems.
