BAT-BMS for Android

BAT-BMS for Android Overview

BAT-BMS for Android is a companion app for smart Bluetooth lithium batteries equipped with a compatible Battery Management System (BMS). Developed by SHENZHEN GRENERGY TECHNOLOGY CO., LTD., the app connects directly to supported battery packs over Bluetooth Low Energy (BLE), allowing users to monitor battery health and operating status without requiring a separate physical battery monitor. It is intended for use with compatible lithium battery systems used in applications such as RVs, boats, golf carts, solar energy storage, and other off-grid power systems.

Battery monitoring highlights

• Connect wirelessly to compatible Bluetooth-enabled lithium batteries using Bluetooth 5.0 Low Energy technology.
• Monitor real-time battery information including State of Charge (SOC), voltage, charging current, discharging current, cycle count, individual cell voltages, and battery temperature.
• View multiple compatible battery packs from a single device and switch between connected batteries within the app.
• Eliminate the need for a separate battery monitor by displaying detailed BMS information directly on your Android phone or tablet.

Smart battery management

BAT-BMS is designed to simplify monitoring of compatible smart lithium batteries by providing direct access to information collected by the battery's integrated Battery Management System. Instead of relying on external gauges, users can review battery status, charging activity, cell balance, temperature, and overall cycle life from their mobile device. This helps users monitor battery performance, diagnose potential issues, and better understand the condition of their battery system over time.

Interface and ongoing enhancements

The Android application features a straightforward dashboard that presents battery statistics in real time while allowing users to move between multiple connected batteries with simple swipe gestures. Recent releases have focused on improving connection stability, fixing bugs, and maintaining compatibility with newer Android devices and Bluetooth hardware.

Controls, connectivity, and Android integration

BAT-BMS communicates directly with compatible batteries using Bluetooth Low Energy and has an operating range of approximately 15 meters under normal conditions. The app supports monitoring multiple batteries, although the developer recommends disconnecting one phone before connecting the same battery to another mobile device. According to the Google Play listing, the developer states that the app does not collect or share user data.

Performance and device compatibility

BAT-BMS is available as a free download through Google Play and supports Android devices equipped with Bluetooth 5.0 Low Energy capability. The app has surpassed 100,000 downloads and continues to receive updates that improve compatibility and reliability with supported smart lithium battery systems.

Alternative to consider

• Overkill Solar — a Bluetooth battery management app for compatible lithium battery systems that provides real-time monitoring of voltage, current, state of charge, cell balancing, temperature, and other BMS diagnostics.
