Product description

Sustained 200A Performance with JK-B1A8S20P The JK-B1A8S20P is engineered for high-demand electrical environments. With a 200A continuous current capacity, it can easily handle 2500W-3000W inverters, making it the go-to choice for off-grid builders who need reliable power for appliances, tools, and electronics. Why Choose the JK-B1A8S20P? Efficient 1A Active Balancing: Unlike passive BMS units that waste energy as heat, the 1A active balancer redistributes charge between cells. This keeps your pack perfectly matched, extending its lifespan and maximizing usable runtime. High-Current Build Quality: Designed with low-resistance MOSFETs and a high-efficiency thermal structure to manage 200A loads safely and consistently. Smart Bluetooth Monitoring: Connect to the JK BMS App to monitor individual cell voltages, state of charge (SOC), and temperature. Customize your protection parameters to fit your specific battery chemistry (LiFePO4/Li-ion/LTO). Comprehensive Safety Shield: Built-in protection against over-voltage, under-voltage, over-current, and short circuits, plus multiple temperature sensors to prevent thermal issues. Technical Specifications: Cell Support: 3S to 8S (LiFePO4 / Li-ion / LTO) Continuous Current: 200A Peak Discharge: 400A Active Balancing: 0.1A – 1.0A (Energy Transfer) Communication: Bluetooth (Built-in); supports RS485/CAN modules
