jslider.. Id pick the Icharger.. as I own both.. I feel the hyperion chargers have poor software and your charge time will be a long one..
a bunch of guys also run the Ichargers and swear that the use of these chargers give there batterys more watts to draw on when tested on watt meter under 20-50 amp loads.. some say 200 more watts.. also a shorter charge time..
I personally dont use either I have 4 vehicles normally when i race so I use venom 210.
