About this app

BMS Tool shows the state of your battery from its battery management system (BMS) over Bluetooth on your Android phone or tablet.

Supported BMS:
- JBD / XiaoXiang smart BMS, also in Liontron batteries
- JK BMS (Jikong)
- Daly smart BMS
- ANT BMS, the older boards and the newer ANT-BLE boards
- Seplos V2 and V3
- Redodo, LiTime, PowerQueen and Starry Sea batteries
- WattCycle batteries
- Wattstunde LiFePO4 and Wattstunde Nova Core batteries
- Ective, LiFeBlue, KiloVault, Enerdrive, Noovi and StartCraft batteries

Features:
- Charge, voltage, current and power at a glance
- Time until full while charging and until empty while discharging, estimated from the present current
- Every cell voltage with minimum, maximum, difference and balancing
- Temperature sensors, alarms and BMS information
- Several batteries in one list, each with its own name
- Search for new devices can be switched off: only your own batteries stay in the list
- Session values and a CSV log of the readings
- History with charts and statistics: charge, power, voltage, temperatures and cells over a day, a week, a month or a year, energy per day, export as CSV
- Alarms as notifications while the app runs
- Home screen widget with charge, power and the last 24 hours
- The display can stay on while the app is open
- One in-app purchase removes the ads for good (lifetime ads removal)

Wear OS:
- The watch app shows charge, voltage, current, cells and details of the battery open on the phone
- A tile and a watch face complication with the charge

The app reads the values of the BMS and does not change its settings.
