My 2018 GMC 3500HD Duramax has the 7 pin wiring harness that provides a trickle charge to my 5th wheel battery while I’m driving. It works great for lead acid and AGM batteries. Should I disconnect this wire if I replace the RV battery with a lithium battery? I assume it’s providing about 13.6v which itself won’t hurt the lithium battery but I’m concerned with the higher voltage lithium hurting either the 220amp alternator or the two onboard lead acid batteries in the truck.
does anyone have any experience with this? I know this isn’t necessarily a solar issue but it is required information in order for me to upgrade to lithium for my future solar plans.
