Has anyone checked the ripple voltage at the balance plug and at the regulator output? I haven't noticed any issues and my servos have no buzz. I have over 200 flights on a system using a CC HV ICE 80, a 350 2S lipo, 2 tech-Aero regulators with separate switches and a connection to the motor battery for the second regulator on the lowest two cells of a balance connector. I feel the two separate switches are very important. I check both lanes for independant operation before each flight. That is difficult to do with a single switch or plugging in connectors. The 350 Lipo will last for weeks without dropping off enough to recharge.

I just tested the set up and it seems to work fine. I did measure about 0.4 volts peak to peak at the input to the Jaccio regulator but the output was clean as I expected it would be. A few years ago I worked with a company that was flying a big helicopter with a TV camera/transmitter on board. The RC system was using the same battery pack as the TV system and every time a servo drew current they could see it on the video. We put a regulator between the battery and the TV system and it filtered out the ripple on the input and solved the problem.
I had been thinking about a redundant power system and this looks like an easy way to do it. While I'm at it I will put a voltmeter on the connection to the bottom two cells that will tell me when I plug it in that the pack is charged (or not). You never want to take off with a pack that isn't charged.
