Higher voltage speed controller?
« on: September 03, 2008, 04:55:46 PM »


I'm looking for a speed boat speed controller to handle a Speed 700BB on 14.4volt (possibly 16.8v), any suggestions please?

Hi Martin..

Don't go for the FUSION, it's an unknown quantity and leave out the Ripmax Sea Sprint as it blows on 12 cells, honest... Have at look at the Jeti 150 (up to 30 cells) thats 36v, or go for the Jeti Navy with water cooling and again up to 30 cells. The Navy's the cheaper of the two by far.
