You're going to be damaging the packs by overdrawing them. Most of the 13:1/1.5J setups I've built for people hang around 20-22amps constant discharge. While your pack might be able to handle the constant, the startup amperage draw spikes rather high, probably closer to the 100amp ranges. This is where the burst rating of the battery pack becomes important. With insufficient burst amperage, this is going to damage a pack pretty quickly even with the setup performing at optimum efficiency. This is generally what leads to the cells breaking down internally causing swelling and possibly fire. Buffer tube lipos are fine for stock setups, what you're building is not stock, it would be a pretty high end build if it holds together and is done right.

In the best case scenario your gun will only shoot maybe 800-1000 rounds before needing a new battery because of the drain on it.

Anything approaching 30 rps, a delayer will help
anything over 30 rps and you will need a delayer to assist in feeding in full auto.

10:1 gears are siegeteks.

SHS makes a 12:1 as well as a 13:1.

Would chaining two lipos and putting them into a crane stock work? or would a full stock w/ a brick lipo.
