JK BMS B2A20S20P 200A Bluetooth BMS 36-60V

Smart multi-voltage BMS for stable, connected battery systems

- The JK BMS B2A20S20P is designed for users who need consistent, safe control of medium to high-power lithium battery packs. With support for 36V, 48V and 60V systems and integrated Bluetooth monitoring, it provides precise cell management for demanding storage and power applications.

This BMS supports lithium-ion, LTO 18650 and LiFePO4 battery packs and is engineered to manage charging and discharging up to 200A. The 2A active balance current helps equalize cell voltages more efficiently than low-current balancers, which supports more stable performance across the entire pack. By continuously monitoring cell status, the BMS helps protect against overcharge, over-discharge and other common causes of pack stress. Bluetooth connectivity allows you to pair the BMS with a compatible app or device for real-time viewing of pack voltage, individual cell status, current, temperature and operating history, so you can adjust system settings and diagnose issues without opening your battery enclosure.

The JK BMS B2A20S20P is suited to battery storage systems, backup power, small-scale energy projects and other applications where consistent output and reliable protection are critical. Its configuration flexibility makes it a strong option for builders and integrators working with different lithium chemistries and voltage ranges in one product line.

Why It's a Smart Choice

• Supports 36V, 48V and 60V lithium packs, reducing the need for multiple BMS models.
• 2A balance current helps keep cells aligned for more stable performance over time.
• Bluetooth monitoring makes configuration, diagnosis and ongoing system checks more convenient.

FAQ
