I am running two Optimas...Redtop is the starting battery and the YellowTop runs the amp and winch
;Dp; ;Dp;

got the RedTop at a MArine base for $99 and no tax
got the YellowTop at AutoZone for like $150

I have a 160 Amp alternator running juice to a 200 Amp battery isolator and then it automatically charges the batteries as they need.....;Dp;
