11.1 lipos, ive fallen in love with. great preformance, but my gun, she can only take so much.
the Big thing to think of when using a 11.1 lipo is when your piston is going to wear out. all batteries will wear out the piston, a lipo will wear it out faster, ergo the more faster it goes.
ive recently redone my entire SAW with a 11.1 2000 mah lipo. i bought a metal racked piston from evike. im sure a new upgraded polycarbonate piston will withstand the force of a lipo for many rounds. Full metal pistons i DONT recomend. but metal racked pistons are a +.
