Nope, without the amps voltage means nothing. Look at it on a larger scale. Say you have a truck or car with a big V8 motor. In order for the starter to crank it over it needs a big battery. Now all car batteries for the most part are 12 volts, (we won't go into the 6 volt or 24 volt systems). Since they all have 12 volt battery you would think one battery could do the job for any motor. Well a 200 or 300 AMP (not mah, we're talking big batteries) won't have what it takes to crank over that big V8 that needs a 500 or 600 AMP battery to power that high torque starter. Same thing goes with AEG's, springs and motors. A heavier spring is like a bigger motor in your car. The AEG motor is your starter. So that little battery that use to crank your stock gun now doesn't have enough juice to crank it over. Time for a battery with more MAH to do the job.
