Question:
We are in the process of putting 2 lithium batteries each is a 100amp into our fifth wheel. The converter that is in there is WFCO WF-9855. What converter to charge the lithium batteries would you recommend that we put in there?

Hey Bob, I checked out your WFCO WF-9855 and it is a 55 amp charger that is NOT compatible with lithium batteries so what you'd want instead is the Progressive Dynamics Charger part # PD79RR that is similarly rated at 60 amps and does have a lithium charging profile.

Hey Bob, how did the Progressive Dynamics converter work out with your two 100-amp lithium batteries in the fifth wheel? Knowing how it performed could help others upgrading from a WFCO unit too.
