I'm not going off the actuator idea but would a good battery pack be 8xAA rechargables put together and then have a heatshrink around them?

Nope, those don't have terribly high capacity and have dismal discharge rates.

You want significantly better cells than those.

[daliad100]

You'll need a lipo charger and possibly a power supply.

I've got a lipo charger that I use for my RC car that charges at 0.5a, 1.a and 2.5a is that good enough?
