2s 6.6v A123 reciever batt?

[zeropointbug]

Hey, I have 2 A123 cells here that have not seen discharge currents in 2 years... I cycled them a few times and they deliver about 2100mah @ 2.5v cut-off (720i)... I am doing some discharge tests on them at 1, 2, and 3 amps discharge. They are all around 3.3volts steady.

So, i ask, is it a good idea to use it as a receiver pack? I know you can get 2s lipo specific servos now, such as the Hitec 7740TH...

So a 6.6volt pack should be about 200oz/in torque and 0.065 sec @ 60deg.... extremely fast servo.

Anyways, can a Spektrum DX2 receiver handle the extra bit of voltage?
