So what voltage is your 2S lipo maintaining all this time?
.
If you set your "backup" regulator to a lower output voltage than your main regulator, the 2S LiPo is just along for the ride . . . sittin' there at idle waiting to be a hero.
.
I set my main regulator output to 5.9V, and the backup to 5.7V. The 2S-350 is still at 100% after a full day's flying.
