What type of battery does this transmitter take and where to get battery and charger new to rc models
Which generation of DX7 do you have?
I have a DX8 first generation. This product is done specially for that type of transmitter: 9067000330-0
As it was expensive and i wanted a balance plug, i took the LiFe 2s 1100mah instead and soldered the plug. Your charger has to include the LiFe mode however. And Spektrum software does not support it, which means the low voltage alarm might come too late... Be aware.
