How to choose the right lipo battery for your RC helicopter? Thare are many ratings that you should know when buying it. There are Voltage / Cell Count, Capacity, Discharge Rating (“C” Rating), Internal Resistance etc.
Today, we are mainly talking about RC Helicopter Battery Voltage from 3.7 Vlot (1s1p) to 44.4 vlots (12s1p) .
About Voltages:
A LiPo cell has a nominal voltage of 3.7V, a fully charged lipo voltage is 4.2V per cell (HV lipo can be charged to 4.35V). For the 7.4V battery above, that means that there are two cells in series. For the bigger rc helicopter such as above 600 class, when you are considering more than one battery in your helicopter, the voltage can easily be increased by connecting them in same series.
