I bought me a new charger when upgraded from 16s to 20s. But you do not need 60V to get 13kw out of that controller.
Here is one of my conf from 2015-06-10

Here is another video I found in my harddrive, when I tested 16s vs 20s. As you can see I got about 300 more rpm in the straight end and as battery amps were the same I got also more kw-s in to the controller. All that was saved by cycle analyst analogger and rpm were calculated from the speed that was measured from the rear shaft by cycle analyst. I had 300A shunt between minus battey wire and from there I got battery amps.https://youtu.be/_HKTkKx89e8
