mcguyver hit the nail on the head about the li-ion battery. A higher C rating wont destroy stuff. It is the maximum sustained current that the battery can push. The battery may be able to handle a constant 40A load, but it can draw less. The power output of the battery is the C rating times the Ah rating. Every pack will have a higher burst rating, so that is why a small 1200mAh 15C battery can still power a PTW. It should put out 18A, but a PTW needs ~30A if I remember correctly.

I'm personally a bigger fan of LiFePo batteries. They have a lower energy and power density, but have a longer life span. The number I remember seeing is 2000 recharge cycles. I doubt it would be that high. Even 1000 would be nice compared to a li-ion. A thing to note, the battery voltage for a lifepo is a bit lower than a li-ion per cell. They output 3.3v per cell, so you can get 9.9v packs. It might be a bit high for a M130, but I don't know. I don't own a PTW, and I'm moving to gas guns so I won't check in my AEGs.
