I just switch from 3s to 4s on my Tarot 650 and it has a much more locked in "Tighter" feel. I think I will need to turn down the PIDs just a bit as it seems to want to twitch every so often, Overall I think I'm sold on 4s
there may be some PID's in need of change, too. rc motors are rated in kv, with means rpm per volt. so when you change the cell count, the motor rpm/dynamics will change as well, and a PID tune may be in order.
@Darren,
Here is a link to the Arducopter wiki explaining the MP voltage/current measuring setup: http://copter.ardupilot.com/wiki/common-measuring-battery-voltage-a...
