(11.1v 2200mah lipo) into ka m4a1

King arms frog king m4a1

Gun is sold as a "lipo-ready" and already fires 🔥 415 with a 7.2v. (I replaced already with a 7.4lipo fires like a charm)

I ordered a burst avocado fet (now ordering a different wire in fet) and a 6.03 (363 ish length) m4 tightbore that will come in a week

Should I wait a week for the fet and the tb or is it okay to test on an 11.1 2200mah?

Consensus is to get a wire in fet and wait or I'll fry my trigger contacts...

Thank you all for the quick responses! Upvoted all who helped! I also found another 7.4 30c 1200mah.
