RX power supply
Hi,
I was thinking about using two separate batteries/switches with two separate connection to the RX. Is it ok to use a servo output for this ?
The setup will contain a primary and backup battery. The primary will be regulated to 5.7v and the backup to 5.1v. Since the voltage from the primary is higher, the backup should only be used if the voltage from the backup drops bellow 5.1v. At least this is my imagination ...
I wonder if this setup is ok for the RX, without any problems ... what do you think ??
Thanks in advance

RE: RX power supply
... the reason for voltage difference is that the backup- battery will never be used if everything works as normal , and by using a li-po, you do not need to charge so often ... Basically, you operate this system as for only one back.
The regulators prevent backflow (inter-gharging between the packs), as far as i know, the RX just contain a bus bar for power ?? ( no component to take into consideration)
