7.4v won't hurt the gun at all, however you should have the proper safety devices in place to make sure you don't cook your LiPo!
If you gun can't pull an M110 spring with an 8.4v NiMH mini, you should invest in a set of torque or super/double torque gears, and perhaps a stronger motor.
What brand/type of AEG are you using?
Tamiya connectors suck.
