Lipo packs must not be discharged below approximately 3.0 Volts per cell. Even a single deep discharge may permanently damage your pack. The tiny Lipo Voltage Guard operates in parallel with your Electric Speed Controller. It will Start a High power piezo Sounder when your pack drops below a preprogrammed voltage threshold. The factory setting is for 3 cells , 3.0V per cell, with 'timed minimum hold'. The LiPo Voltage Guard may be easily reprogrammed to suit your own requirements with your transmitter/ receiver the supplied programming lead and your flight pack or power supply capable of any voltage between 5 and 45 volts.
