Bluetooth battery monitor BatteryCheck handles lithium, features improved app

Five years ago, BMPRO offered the Australian RV market a world-first, patented, innovative wireless monitor, BatteryCheck, which enabled the ability to monitor a caravan battery via an app on the smartphone and easy-to-install device fitted on the battery.

Previously caravaners only knew the status of their battery by the rather crude method of measuring volts, which could be unreliable and changes very quickly leaving the caravanner with no sense of security in really understanding the capacity of their battery.

Made it rather difficult to go bush with any sense of really knowing what was happening with power, until BatteryCheck was introduced! BatteryCheck enabled caravanners to better understand the mystery inside the battery by providing valuable information on the health and status of their battery. This allowed caravanners to become more experienced and more comfortable in really what their energy status was, ensuring that the beer was always cold, and food was not spoilt – hassle-free adventures!

Today, we are excited to announce two new BatteryCheck series models are available – BatteryCheck100, a highly accurate monitor, handling current requirements under 100A, and BatteryCheckPRO, monitoring high currents up to 300A, and compatible both with lead-acid and lithium (LiFePO4) deep cycle batteries. BatteryCheckPRO is recommended to monitor your battery if you are using a microwave, inverter, CPAP machine, hairdryer, coffee machine, or other energy-demanding equipment.

The new app, BatteryCheck100+PRO, has a modern look, features easy to read table and graphics, and provides all the vital information on battery health at a glance.

Battery parameters monitored are:
• Voltage and Temperature
• Charge/Discharge Current
• State of Charge (SoC)
• State of Health (SoH)
• Estimated Discharge Time Remaining

A simple DIY installation, the new models are easy to retrofit and enabling monitoring of multiple batteries in parallel. The latest Bluetooth technology warrants reliability and enables to use of the device wherever you travel.
BatteryCheck100 and BatteryCheckPRO are great for caravanners, 4WDers and anyone with a secondary battery, however, they are not designed for the under-bonnet use or cranking applications.

Both models are available to purchase online at and via BMPRO authorised resellers. BatteryCheck100 retails for $225 and BatteryCheckPRO is available at $295.
