I use my 2020 Colorado Duramax to pull my Nucamp TAG teardrop camper that weighs around 1300 pounds. I have ordered a Battleborn 100 am hour Lithium Iron Phosphate battery to replace the Interstate SRM 24 marine deep cycle lead acid battery in my camper. Per my truck instructions I use the tow haul mode which boosts the voltage up to 14 volts when towing. I will be using one of the Battleborn batteries only in the camper. When I arrive at the campsite I disconnect the trailer from the truck to prevent discharging the truck battery. The lithium battery has much less resistance compared to the lead acid battery, and I am presuming will pull more current when low. I will charge the Lithium battery with a dedicated lithium battery charger before hitting the road. The charge pin on the factory 7 way pin has a 30 amp fuse. Questions: 1. is the alternator going to charge this camper lithium battery ok going down the road. How may amps will it push through the factor wire connecting the 7 way pin charging pole with the factory bus? 2. Is the Lithium camper battery going to pull so much current it damages my alternator, or will the 30 amp fuse simply blow it it gets to pulling too much current. 3. Do I need to use a battery isolator? Amy time the truck is turned off when I stop at a campsite I unplug the trailer from the 7 way so it cannot drain the truck battery overnight. Thanks for any insite you can offer!!!
