Help!
DynamGrand Cruiser questions

Hi guys. I was looking for a 2200maH 11.1v 20C battery for my Grand Cruiser, and I can't seem to find one anywhere. Are there any alternatives that I can use without ruining the plane?? Thanks!

Would this fit?

Sky Lipo 2200 25c

Not sure if you're worried about the 25 C, but that shouldn't be a problem.

You're welcome. If a 2200 mah 3s is what you already have, switching from 20C to 25C won't burn your motor out (unless you were on the hairy edge of burning it out).

Usually, all other things being equal, a higher C will mean less internal battery resistance (technically, it is also possible for manufacturers to game C ratings by dissipating more heat without changing internal resistance, though).

This means in theory more energy delivered to the motor over the whole flight, and less power disappated as heat in the battery. Reduced internal battery resistence might also mean slightly more current at full throttle, all other things being equal, which shouldn't be a problem unless you were on the hairy edge of your ESC/motor limits.
