Hello. I’ve searched the forum and can’t seem to find the answer. I have a 2020 Outback 328RL. I’m wanting to switch over to two 100ah lithium ion batteries connected in parallel. It will still be 12 volts. Will the factory installed converter/charger work or will I have to replace it? Thank you so much.

Your current WFCO WF-9855 converter is designed to charge only lead acid batteries. Direct replacements are WF-9855-LIS which has a switch for selecting either battery chemistry OR the WF-9855-AD which has an auto-detect feature. Keystone RV has begun installing the latter in the 2022 models.
