Like any other battery, you have to match the li-po to what the gun can take. "Li-po ready" is as much BS as "Canadian legal".

while your main point is correct the way in which you present it is incorrect,

it isn't the amperage that damages the gun, it's actually the wear-and-tear due to higher VOLTAGE
(and the speed that it creates) that usually kills AEG gearboxes.

normal (NICAD/NIMH) packs usually do not match the amperage draw of an AEG motor, where as most Lipo's will
(this is better then the motor being 'starved' of current to be honest)

as an example, if i had a battery with infinite amperage but at 7.2 volts i wouldn't kill it any sooner then a 9.6 volt NICAD/NIMH

if however i had even a 22.2v (or there-abouts) battery (NICAD/NIMH or LIPO) then i think we can guess the lifetime wouldn't be so great..

it is also important to differentiate wear due to excessive speed and breakages that can be due to excessive speed..

the wear-and-tear can be shown with the 'limited milage' model:
In simplistic terms, AEG components (without exceptional defects) have a life expectancy, measured in shots fired..
if you increase the Rate Of Fire you are just hastening it's demise,

Breakages due to excessive speed would involve anything that was caused by the excessive speed, example:

If you took a standard out-of-the-box tokyo marui firing at around 300fps..
then if you took said gun and used a 22.2 or 33.3 volt battery the motor would move the gears to fast that the piston
wouldn't have time to move forward fully before the next rotation (Que horrible grinding sounds from piston teeth being chewed off)

note that this is unlikey to happen with 'normal' (sub 12) voltages and upgraded guns (which would have a faster moving piston)

of course, i have used a FAMAS with a 12 volt battery for a couple of games and it didn't miss a heartbeat.. you take your chances!
