Been playing with a Weatronic RX on the bench and noticed that the red led keeps swapping from one blink to two blinks which means that the RX is swapping from the primary battery to the backup battery. Looking into the settings the switch over voltage of 5.7V. But looking at the recorded data on the SD card I can see the voltage in primary battery was 6.9V when it swapped and not 5.7V. Also noted that the RX would swap back to primary battery after a relatively short period of time, 20-40 seconds.

Anyone else seen this behaviour? Should I be concerned?

FYI Firmware is latest(1.4.6).

Thanks

Geoff.

The 5.7 Volts relates to after the regulators.
You have to add 1.2 Volts for the regulators. That makes 5.7 plus 1.2 V = 6.9 V. Sounds correct to me. Try the setting of Lipo with 6 V and you will see the switching at 7.2 V.

Thanks

Gerhard
