He rates the D3100s at 2500wrms for comps and 5000wrms for daily systems. I prefer using math though. What alt(s) do you have?
1 DC power 270sp but was custom built.from rob... does 198@ idle....
and This for a Warhorse... my plan was.... to put 1D3100 under the hood and use that for the starting battery and for my 4channl & accessories... then 4D3100's in the back dedicated for my Warhorse only...
I think you'll be fine with 5 d3100s. The tech behidn the warhorse keeps current draw low. its got a max draw of right around 800 amps give or take. thats a third less than I have for the same power. I thought you were doing two?
