Another Charger/Converter question...

I've got a "just fits" dual 6V battery box on the way and a Costco trip planned to pick up a pair of their GC batteries. Before I do this "conversion", though, I want to replace my WFCO converter/charger.

I've done a deep dive into forums here and other sites regarding setting up ideal charging configurations, and within that I've seen mention that the best "boost" charge voltage for 6V flooded GC batteries is 14.8 volts, rather than the more common 14.4 for other types.

I like everything I hear about the Progressive Dynamics 9200 but nowhere have seen that they provide for a different "mode" for boost charging the 6 volt GC at any different voltage than their normal 14.4 volts.

Is it just wishful thinking to contemplate finding a converter/charger that will do the 14.8 volt boost? If so I'll just order me a PD9260 and get on with it...

By the way, THIS appears to be the best price I can see for it -- should I grab it?
  • I believe the 14.8 is custom made for Randy or Randy modifies them with PD approval.
    Warranty is good either way.

    I assumed (from all references I can find) that the PD will only deliver 14.4 volts. I supposed the little extra that a 14.8 volt charger can squeeze in probably isn't worth the trouble trying to get accomplished (probably would need to find some higher-priced charger somewhere).

    Any other input before I press the button on ordering this thing is welcome...


    The one with the C delivers 14.8 v. Looks like they only make two. 45 amp and 60 amp model.

    You dont need the pendant dongle. Thats only for convienance. There is a button inside the door. You can accomplish the same thing.

    Yes 14.8 volts is a big deal over 14.4. Its definatly worth the upgrade .. But IMO thats if your an avid boondocker. Off generator you can charge 90% in a few hours.

    For sure Randy at BESTCONVERTERS can provide you a special PD converter that produces 14.8VDC for boost charging. I don't know if you can order one of those from Progressive Dynamics directly or not...

    Get in touch with Randy at BESTCONVERTERS for info on their PD 9200-14.8 Volt Deck Mount...

  • The 9260's boost is 14.4VDC.
    When the battery's are low I see 55~57 amps delivered to them. That has worked great for my 6v's.
