Hi...as per my knowledge if you want to go high volt. We have a quad set up, one for the 12v side charging at 14.8, and three for the 16v side charging at 17.9 with 20 xs power d1600s. It was and has been a pain. This season is the first its ran with out issues. The blue transpos are turds, can be finicky as fuck. But, so far, its been fine this year after much playing around.
