Questions and answers of the customers

A LiPo alarm / tester is a must have piece of equipment for any flight box. LiPo batteries require careful management to maximise their life; they can be charged up to 4.20V and discharged down to 3.0V per cell. Any lower or higher in voltage and the cell will almost certainly be irreversibly damaged (reduced capacity or total inability to accept a charge). Furthermore, a damaged cell may become unstable which can be very dangerous (increased fire risk). A LiPo alarm / voltage tester is therefore an essential piece of kit to monitor the status of your individual cells and avoid damaging them.
Most pilots who fly without a telemetry feed use a LiPo Alarm on board their craft to alert them as to when it’s time to land – it’s recommended to set your alarm to 3.6V to give you enough time to land safely.
