BMS Monitor: LiFePO4

BMS Monitor: LiFePO4 helps you monitor compatible JK BMS battery systems locally over Bluetooth.

View essential battery information in one clear interface:

• state of charge, voltage, current and power
• charging and discharging status
• estimated remaining operating time
• individual cell voltages, minimum, maximum and voltage difference
• battery and MOS temperatures
• balancing activity, alarms, cycle count and battery health
• local history charts for charge level, voltage, current and temperature

Advanced users can unlock selected BMS controls using the settings code stored in the connected BMS. The app supports selected protection settings, charge and discharge control, low temperature charging protection and changing the BMS settings access code. Every supported change is sent directly to the BMS over Bluetooth.

Create a local settings backup, restore it later, or export it as a JSON file. Battery history, language preferences and local backups remain on your device unless you choose to export a file.

No account or cloud connection is required for BMS monitoring. The app includes English and Polish languages and a demo mode that can be explored without battery hardware.

Compatibility depends on the exact JK BMS model, firmware and JK02 protocol variant. Always verify important protection values after saving them. This app is independent and is not affiliated with or endorsed by JK or JiKong.
