This project involves the development of a keyfob-like device powered by an Adafruit ESP32 Feather S3 TFT Reverse board, utilizing Bluetooth Low Energy (BLE) to communicate with JK BMS batteries. It allows users to read battery information and control charging, output, and balancing features directly from the keyfob.
- Real-time Battery Monitoring: Fetch and display real-time data from JK BMS batteries including voltage, current, temperature, and more.
- Control Charging: Enable or disable charging of the battery with a simple button press.
- Control Discharge: Enable or disable the output of the battery to connected devices.
- Control Balancing: Enable or disable the balancing feature of the battery.
