Active Balanced BMS & Balancer — Smart Battery Protection with Active Balancing
This collection features JKBMS intelligent Battery Management Systems (BMS) and Active Balancers, designed for LiFePO4, Li-ion, and LTO battery packs used in home energy storage, solar ESS, and inverter systems.
What is Active Balancing?
Unlike traditional passive balancing (which wastes excess energy as heat), active balancing actively transfers energy from higher-capacity cells to lower-capacity cells — improving overall pack consistency, extending battery lifespan, and maximizing usable capacity.
This collection includes:
-
Active Balanced BMS — combines battery protection with built-in active balancing
-
Active Balancers — standalone balancers compatible with JKBMS hardware BMS units
-
Relay BMS — high-current relay-controlled BMS for industrial and heavy-duty applications
⚠️ Note: The standalone active balancer is designed to work with JKBMS hardware BMS only, replacing the passive balancing function.
