I have lots of experience with three stage converter/chargers, especially the Progressive Dynamics ones. But all my experience is with flooded cell batteries, not AGM's.
A question for those in the know (Lewster especially). Does the PD three stage converter/charger play well with AGM batteries? I understand of course it does not have battery temp compensation, but are the charge voltage ranges correct? How about the boost voltage applied every 20 hours? Will it hurt the AGM batteries?
With the many factory single stage Paralax units being combined with the factory solar systems which have AGM batteries, I know this is a real issue in many new rigs. What I don't know is what replacement converter/charger will do the job best and why.
I know that Magnum has a full inverter/charger which is AGM compatible but it is very expensive and not everyone wants or needs a large inverter for their trailer.
I look forward to specific suggestions and reasons.
