I run 6 servos and ignition off the single airborne battery. The ignition uses the Tech Aero ibec.
The battery has been 1800-2200 mah capacity 2s lipo and gives about 75 minutes of flying. The end voltage of the 2s lipo is 7.45 to 7.5 V for the 1800 and about +.1 V for the 2200.

The 2700 Shawn suggests should give one hour of flying if the smoke pump uses about 500 mah. Let's keep in mind the smoke pump will be run a fraction of that hour. What's not known is whether the pump generates RFI back to the RX.

I check the airborne bat voltage after the 4th and 5th flights. I track flight time as well
