This lipo battery is an upgrade to stock Spektrum 2000 mAH NiMH battery that comes with the Spektrum DX7S or DX8 radio. With 4000 mAH, it will give you double the play time, plus it's much faster to charge a lipo than NiMH. Designed to fit nicely into the battery compartment of DX7 S or DX8 radio, all you need do to is throw away the battery foam that comes with the stock battery and set your DX7 S/DX8 radio to lithium polymer battery mode. 

*** This battery comes with protection circuit board (PCB) that will cut the power in case any cell voltage drops below 2.8V to protect the cell. It helps when you forget to turn the radio off and it tries to drain all the power of the battery. The PCB will also restrict the charge to 4.2V to prevent any overcharge.    

*** This pack is recommended to use for the DX7 S/DX8 radio transmitter only, not as a receiver battery.
