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.

Works fine
I use it to monitor my LiPo voltage that powers my electric aircraft. Works fine and shows correct voltage when compared against voltmeter. Since checking LiPo voltage is the most critical telemetry parameter in electric aircraft I wish that Graupner would follow HiTec and Futaba brands, where that feature is built into receiver, meaning you do not need telemetry sensor, instead you have a port on receiver to plug in wires that come from LiPo positive and negative wires.
