Makes sense, that it's all onboard, Thank you!If the charging arrangement is the same as the Horus X10S which also uses a 2S pack then what happens is the charge controller in the radio does a switch mode and balance from 5volt to the required voltage for a 2S pack. Its all done inside the radio. FRsky recommend a 5 volt USB source of 2.1 amps. I use my Samsung charger and this works fine. A lower current supply also works but takes longer.
