I fully understand the slow roll during warm start ups. I’m just wondering how you guys running dual batteries with an isolator we’re performing ? My 15 non turbo XDS has winch, light bars, lighted whips, belt temp gauge, fan over ride, and an 8 speaker amped Mayhem Roof system. Yes I’m pulling a lot of extra amps and have only had to jump start it 3 times but this is getting old, now I need to upgrade. Looking at Odyssey 925 and a True isolator. The question is the isolator, Does anyone have the isolator that has the button that uses both batteries at start up ? I have followed the 27 page thread on this issue and haven’t seen much lately.Any help would be great. Another question, can you use the OEM battery for the extras and use the odyssey for start up ? Or do they need to be the same batteries?
