Replacing standard batteries with lithium on a 2021 Grand Design TT
Not sure if this is the right place for this question but I am looking at a 2021 Grand Design TT to replace our current trailer and I'm wondering about upgrading the batteries from the start. The model that we are looking includes a solar panel and charge controller and I'm wondering if instead of getting a pair of 6v batteries getting a pair of battle born lithium batteries. My only question is if I would need to replace the factory charge controller to do that or if I can just install the batteries now?
Eventually I'd like to upgrade the 165W solar system and add additional battery capacity but I'd like to make the investment upfront for a few of the lithium batteries.
TIA!
