Product description

JK-B2A25SRP: Professional 7S-25S Smart Active Balance BMS (Relay Version) The JK-B2A25SRP is engineered for high-voltage battery packs where safety and longevity are non-negotiable. Designed for 48V, 60V, 72V, and up to 100V systems, this BMS uses an external relay instead of internal MOSFETs, allowing it to manage massive industrial-grade currents while providing industry-leading 2A active balancing. Scalability & Parallel Configuration: The JK-B2A25SRP offers exceptional flexibility for large-scale battery banks: Unlimited Parallel Theory: The BMS hardware itself does not impose a strict limit on the number of parallel cells (P-count). Theoretically, you can parallel an unlimited number of cells to achieve your desired capacity. Engineering Reality: In practical engineering, the maximum P-count is primarily determined by the individual cell capacity and the BMS current sampling precision. For optimal performance and SOC accuracy, it is recommended to balance your total capacity with the sampling resolution of the shunt. Why Choose the Relay Version? By decoupling the current-carrying component (the Relay) from the logic controller (the BMS), the JK-B2A25SRP ensures that the heat generated by high-current discharge does not affect the sensitive balancing electronics. This results in a much more stable and durable system for: Energy Storage (ESS): 48V Solar wall/Rack systems. Electric Vehicles: 60V Forklifts and utility carts. Heavy-Duty RVs: 72V High-capacity off-grid power banks. Technical Specifications: Cell Support: 7S to 25S (LiFePO4 / Li-ion / LTO) Active Balancing: 2A (Energy Transfer) BMS Type: Relay Version (External Relay) Connectivity: Integrated Bluetooth, CANBUS
