Description
When 2A isn't fast enough, the JK-B4A24S steps up. Delivering a constant 4A balancing current via ultracapacitor energy transfer, it handles larger-capacity battery packs that need faster cell equalization — keeping voltage differences minimal and the pack running at full potential.
Designed for 2 to 24 series configurations, the JK-B4A24S supports cascade installation for systems beyond 24S, and includes Bluetooth app monitoring as standard. Optional RS485 or CAN communication allows seamless integration with inverters and BMS systems.
