Product description

Drive Heavy Loads with the JK-B2A8S30P The JK-B2A8S30P is built for enthusiasts and professionals who need massive current delivery without compromising on safety. Designed to handle 300A continuously, it easily powers large 3000W-5000W inverters, air conditioning units, and heavy-duty appliances in mobile or stationary energy systems. Key Performance Benefits: Pro-Grade 2A Active Balancing: Most high-current systems suffer from cell drift.

Smart App Integration: Monitor your battery's SOC, individual cell voltages, and temperature sensors via Bluetooth. The JK BMS App allows for precise parameter tuning to match your specific battery chemistry. Multi-Point Safety Protection: Advanced hardware monitoring prevents overcharge, over-discharge, and short circuits, while integrated temperature probes guard against thermal issues. Technical Specifications: Battery Configuration: 4S to 8S (LiFePO4, Li-ion, LTO) Continuous Current: 300A Peak Discharge: 600A Balancing Current: 0.1A – 2.0A (Active) Connectivity: Integrated Bluetooth; supports CANBus/RS485 customization.
