Details
Designed for home energy storage packs, the JKBMS smart BMS combines active balancing with inverter-ready communication options.
A layered internal build supports stable current handling, cell sensing, and communication hardware inside a compact enclosure.
RS485 communication is standard, while CAN and heating interfaces may be available as customization depending on the configuration.
Built-in Bluetooth allows Android/iOS monitoring for live pack data, per-cell voltage, and status checks.
Protection functions cover charging/discharging limits, short-circuit response, temperature protection, and cable-drop/poor-contact alerts.
