It was the hc 600 thats has more power than a hundred 1 farad caps and the hc800 thats better than 200 1 farad caps...? If I can remeber correctly in their ads.. good question but not even a 100 farad cap or 100 1 farad caps can handle a 100,000 WATTS!! When 100 1 farad caps are all drained they become a much bigger extra load for the alternator to restore only to have them all drained out again in less than a second..Where as the kinetik requires much less and more a storage instead of a sucker!! Caps= suck and spit and suck!! Batteries= store all your wasted power then gives it to kindly,LOL!!
