Will this (WFCO WF8955PEC) charge lithium with out me doing nuttin ? The manual sez it will but does not say if any mods required . While I got ya here , if I wanted 200 amps lithium would ya buy a 200 or 2 separate 100s ?
Yes it will charge fine. May short charge a bit (90%-95%) if it sticks at 13.6 volts. No harm in a short charge and may live a bit longer for it. Still way more usable capacity than FLA.
200 vs 2x100 is a bit tricky. Generally I would say save the money and space to get the single 200. However people periodically have issues with LFP and if one does not operate as expected hopefully the other would keep the RV going. If the future may want 400... maybe the single 200 now and add the second if still wanted or needed. Your call.
Please follow up with a trip report :)
