- "No" (default) - no backup battery is present and the BEC voltage is set to the value specified in the configuration. No external power must be connected on the receiver side or the BEC will not turn on.
- "2S LiPo 8.4V" - on the receiver side an external power supply with a maximum voltage of 8.4V is assumed (see picture). The controller is not initialized if the voltage of the backup battery is outside the operating limits (or not connected). The BEC voltage is automatically adjusted according to the backup battery voltage, so there is no risk of uncontrolled currents.
- "2S LiFe 7.2V" - external power supply with maximum voltage 7.2V is assumed on the receiver side. The behavior is similar to the 2S LiPo.
