You really only need to use another 1S lipo in the switch line. Now we are getting down to little micro helicopter batteries.

With this modification the voltage cutoff WILL NOT WORK.

Good options for 1S setups with the RS.

LiFe 6.6v receiver pack

5cell or 6 cell Nimh or NiCd

1s or 2s lipo in line with the switch.

2s lipo with a 6v regulator

Booster connected to the main 1S lipo

Using a Diode to drop the voltage of a 2S is not bad, but a little more complicated to wire if you want full voltage to the servo.
