Blaze92 Posted March 16, 2014 Report Share Posted March 16, 2014 Should I use 14.4v or 12v to calculate the recomended rating for the Amperage of a HO regaurding a systems X amount of watt/rms ? Example equation. 3500 (watts) / 14.4 v = 243A. Link to comment Share on other sites More sharing options...
TaylorFade Posted March 16, 2014 Report Share Posted March 16, 2014 I use 10v so there's a fudge factor for efficiency and what not. 3500w / 10 = 350A Link to comment Share on other sites More sharing options...
