Yeah you have to split your battery pack in 10S.

So in this way you can charge your 20S pack.

Re: iCharger 4010 Duo review

From my experiences I will not buy this expensive charger again.
You will not be able to repair by yourself, everything has been scratched out and customer service will not reply to you questions.

Running time for this charger was only few times in a half year.
