The Deans micro are good, the JST are ok but a little weak both electrically and mechanicaly. I use the full size Deans just because I like them and use them for anything bigger than a Speed 300, even though the're total overkill. My BCP goes about 15-20 min on a 1050 lipo hovering only. You don't have to charge through the 4-pin if yyou do not have the proper equipment/conncetor, but it is better. Some packs only have one set of leads. Buy a lipo guard device with a light or beeper for your voltage. You will however notice it flies poorly a little wile before it dumps but you may think it's pilot error. have fun
