JKBMS Active Balancer JK-B5A24S — 5A 2~24S Battery Equalizer for Commercial ESS

JKBMS JK-B5A24S — 5A Active Battery Balancer for 2~24S Commercial & Industrial Packs

The JK-B5A24S is built for demanding commercial and industrial battery applications where fast, continuous cell balancing is non-negotiable. Delivering a constant 5A balancing current via ultracapacitor energy transfer, it handles large-capacity packs with ease — keeping every cell in tight voltage alignment and the system running at peak efficiency.

With a built-in power-on switch, cascade support for systems beyond 24S, and optional RS485 or CAN communication, the JK-B5A24S integrates seamlessly into professional energy storage installations. It also serves as a powerful tool for large-capacity battery pack recovery — rapidly restoring heavily imbalanced or degraded cells.

Key Features

• 5A constant active balancing current — high-speed equalization for large-capacity cells
• Supports 2~24S configurations — LiFePO4, Li-ion, LiPo, LTO, lead-acid
• Cascade capable — expand beyond 24S by linking multiple units
• Power-on switch — manual control over balancer activation
• High-precision voltage monitoring — ±3mV accuracy per cell
• Bluetooth connectivity — monitor and configure via mobile app
• Optional RS485 or CAN communication (one of two, select at order)
• Optional temperature sensor input
• Battery pack recovery — ideal for restoring large degraded or imbalanced packs
