I have a 2013 travel trailer that needs a new battery so I want to switch to lithium for those overnight stops and occasional 2 night boondocking trips when traveling. Going to purchase a 200ah LifePo4 and a WF-8950L2-MBA to replace the current lead acid charger in the stock WFCO8955...I don't have or want solar and don't need to charge the battery while driving as I will always have a generator with me to plug into to charge up the battery as 80% of our camping is on hookups. I have a 18 F150 as a tow vehicle. Do I need to do anything to the 7 pin connecting the trailer to the truck for the new lithium battery? I don't care about the small charge it may get from it and I don't want to install a DC to DC charger either I just don't want to harm the truck or new battery is all. Thanks Much everyone.
