I run a 3 pack on my M8. It's a perfect match. 12.6v is no problem for a radio. Nimh cells are that high off the charger. Lots of guys are starting to run 3s transmitter packs.

Also, most radios have a low-voltage alert between 9-10 volts. Perfect for a 3s.

As long as you don't accidentally leave the radio on overnight.... (don't know how low the radio will continue to stay on, draining the pack but I'm assuming it will go way down... so bye-bye lipo)

Mine is a 3500mah pack so me thinks it will last a while before I need to charge it. :D
