Monitor your LiXX batter pack with the Graupner Voltage Module 2-4S using any Graupner HoTT telemetry system. Maintain continuous cell voltage monitoring when the battery is connected to the module via the balancer connector. Program the module to trigger a warning alarm if the voltage drops below a programmed value. Never be caught unawares again.
This Voltage Module has an additional XH plug used to power Alpha 250Q copter external devices (i.e. FPV gear and cameras).
