Check PowerXtreme PRO, developed by PowerXtreme, for monitoring and managing PowerXtreme LiFePO4 batteries used in caravans, motorhomes, and marine craft. The app connects to the battery BMS via Bluetooth Low Energy to display state of charge, voltage, current, temperature, and cycle count in real time. It also supports OTA firmware updates, remote storage mode, heater control, and multi-language displays. The interface suits owners who need phone-based battery visibility and basic remote control; the app requires Android 5.0 or higher and Bluetooth 4.0 support.

What telemetry and controls does the app expose?

The app presents live metrics such as SoC percentage, voltage, current, temperature, and a cycle life counter directly from the battery BMS. It offers remote actions as well, including storage mode activation and heater control, plus over-the-air firmware updates and a direct service report submission path. For multi-battery installs the app lets users assign recognizable names so each monitored unit is identifiable in the device list.

Does the app keep a reliable Bluetooth link to the battery?

The app uses BLE to communicate with the battery, and the requirements state Android 5.0 or higher with Bluetooth 4.0 support. Recent updates have improved connection stability, but user feedback still notes occasional Bluetooth pairing difficulties typical of BLE utilities. Direct BMS integration removes the need for external shunts, so when the link is stable the app reads internal metrics without added hardware on the battery circuit.

Is it safe to perform firmware updates and storage commands from the phone?

OTA firmware updates and storage mode control mean the app can write settings to the BMS and switch battery output off for long-term protection. These are explicit capabilities, so apply updates and storage actions with care and while the battery has stable power available. The app’s service-report feature provides a channel for diagnostics if an update or setting change requires technical follow-up.

Do non-technical owners need specialist skills to operate it?

The dashboard exposes core status metrics in plain terms and supports multiple languages including Dutch, English, German, and French, which reduces the need for specialist knowledge. Renaming batteries and reading SoC are straightforward. Advanced operations such as firmware installation and storage-mode activation are accessible but benefit from basic familiarity with battery handling and the requirement to maintain a nearby phone for BLE connectivity.

Good fit for hands-on RV and marine owners, with a platform requirement caveat

PowerXtreme PRO is a practical choice for owners who want phone-based oversight and occasional remote control of their PowerXtreme battery systems. The main limitation is the platform dependency: it requires Android 5.0 or later and Bluetooth 4.0, so older phones cannot run it. Practical tip: perform maintenance tasks while the battery has stable power and keep your phone within the BLE connection range during critical operations.
