Last Week, I finishes my first mini quad build, and wait the last components-Lipo battery. I bought this Lipo batteries from Tattu 2days ago, and the battery came in the mail today, it is very fast. This is a 1300mAh 4S Lipo and cheap balance charger from Hobbyking. My question is Does anyone know what the voltage should read when it's fully charged? Stupid question I know, what can I say I'm bran new. Thanks in advance.
