The thing is i believe the heli came with the li po charger. i also have syma s34 (the new chinook) and s34 comes with lipo battery and both helis use the same charger. I didnt know that u can use lipo chargers on li-ion.... at least this is the case with s34.
So what kinda of lipo should I get in order to safely upgrade the battery (i dont wanna fry the mainboard or motors)? should I stay with 7.4v? I am planing to use the stock charger which I believe 2cell lipo charger (can anyone confirm that?)
I agree, I would not exceed the 7.4v. Have you many flights with the S34, do you like it? I have a S022 Big Chinook and loved it but after a while it started having problems with it not responding to controls. Syma products seem to be infamous for this.
