Safety Warning:
If you are purchasing this pack to be used with a UDI quadcopter, you must use a lipo charger that regulates voltage and outputs no more than 4.3 volts DC. Do not use any charger that exceeds this rating. Doing so is a great safety and fire hazard. These batteries are compatible with the quadcopter but not with the typical stock charger that it ships with.
