Li charging is unique and for the best results use a good lithium compatible charger. Many may say WFCO isn't a good charger even for flooded.
Consistent with WFCO the wiring may be to small for the length and you might want to upgrade the wiring from the charger to the LI battery. Locate the charger closer to the battery if you can. Fuse any new wiring.
Then depending upon you "new" power needs other wiring updates could be considered. There are a lot of variables depending upon what you want to accomplish now and perhaps in the future.
