Use your HoTT radio to provide real-time telemetry for main battery pack information with the Graupner VM-80 Voltage Module. Avoid excessive battery drainage for batteries up to 80V DC by pre-setting minimum voltage alarms and voice notifications to alert you when value fields have been crossed. Never be caught unawares again.
The VM-80 is super compact and lightweight, lending itself extremely well to powered sailplanes or foam gliders. It is easy to install, requiring only main lead battery pack connection and a single-wire receiver telemetry input port before becoming operational.
