About this app

Monitor and control your battery over Bluetooth — no cloud account, no internet, no subscription.

JKBMSR BLE connects directly to your Battery Management System (BMS) over Bluetooth Low Energy and shows live telemetry: state of charge, pack voltage, current, power, per-cell voltages, temperatures, and balance status. Everything is read from real hardware — there is no demo mode and no fake data.

SUPPORTED BRANDS
JK-BMS, Daly Smart BMS, JBD / Xiaoxiang / Overkill Solar, ANT BMS, Seplos active balancer, Basen, KS48100, Lolan, Tianpower, and Topband. The scanner detects your brand automatically and even flags unrecognized devices that look like a BMS ("Possible BMS") instead of hiding them.

LIVE TELEMETRY
- Animated state-of-charge ring, pack voltage, live current and power
- Per-cell voltage grid with min/max highlighting and balance delta
- MOSFET and probe temperatures, wire resistance where reported
- Session balance trend and per-cell detail sheets

SAFE CONTROL
- Charge / discharge / balancer switches — only the ones verified for your brand are shown
- Every control is gated behind a Security PIN you set (default 1234)
- Per-field locked BMS parameter editing for JK, Daly and KS48100

PRIVATE BY DESIGN
- No account, no tracking, no analytics — settings live in a local database on your phone
- No location permission needed on Android 12+
- Optional in-app tips support development via Google Play Billing

JKBMSR BLE is an independent monitoring solution. It is not affiliated with, endorsed by, or sponsored by any BMS manufacturer.
