JKBMS Active Balancer JK-B15A24S — 15A 2~24S Industrial Battery Equalizer

JKBMS JK-B15A24S — 15A Active Battery Balancer for 2~24S Industrial & Large-Scale Packs

The JK-B15A24S is the industrial flagship of the JKBMS Active Balancer lineup — and the most powerful. Delivering a constant 15A balancing current via ultracapacitor energy transfer, it is engineered for the most demanding large-format battery systems where speed of equalization directly impacts system performance and uptime.

At 15A, it is not just a balancer — it is a battery recovery powerhouse. Heavily degraded or severely imbalanced large-capacity packs that would take days to recover with lower-current balancers can be brought back into alignment in a fraction of the time. For industrial ESS operators, battery maintenance professionals, and large-scale solar installations, the JK-B15A24S is the definitive tool.
