I'm building a device that senses vibration and sends serial data via a bluetooth module connected to an arduino pro mini 3.3v, and so far I've been using a 3.7v, 370mAh lipo ipod nano battery for my tests, and it's worked fine. As I refine the device to a smaller size I'm trying to scale down on battery size as well, and when shopping online for batteries, most of them seem made for RC helicopter purposes and have an additional specification that my current lipo doesn't have printed on it, the "C" rating for discharge rate (in the case of the ones I just ordered before doing research, they are rated at "25C".)
I've done some google searches about that discharge rate and read some hobby forums but I can't find a clear answer about this that isn't about RC helicopters. Would 3.7v, 350mAH 25C batteries be a safe replacement for my current 3.7 volt battery (which I can't find discharge rate for)? If not, any suggestions for small lipo batteries I should use in its place?
Thank you, I apologize if this is in the wrong forum it seemed the closest fit to my problem
