Might have found charging spec's for GC2's
The Sams Club/Costco GC2 6v golf cart batteries are in wide use now and many have reported years of trouble free use. Many have asked for the proper charging spec's including my self and I've never fo...

There is the "home front" PowerMax PM4s with the stated specs as above (which might be out of date or wrong, perhaps referring to the PM3s) while Randy at bestconverters, who is a PM dealer, but also makes/modifies his own versions of the PowerMax line, has his- called PM4Bs- that go to 14.6 instead of 14.4 like the older version PM3s
I can't say what the "real" specs are for a PowerMax PM4 and a Randy PM4B if they are different.
No, PowerMax does not want to have a remote gizmo like the Charge Wizard or IQ4. It does what it does. It (PM4s and PM4Bs) does go into boost first at whatever battery SOC and stays there for 15 minutes. If battery voltage is then still below 14.2, then it will continue in boost until 14.6v. If it is over that 14.2, it will drop to Absorption at 13.6 and do the rest of the recharge at the 'gentle rate' they believe most customers (or at least their RV makers they hope to be the original provider for instead of WFCO etc) want.
It seems the RV makers have their own ideas of what the customer needs and that is what the converter maker has to provide, never mind what the customers really want (if the customers have ever even been asked)
PM believes we who want high amp fast charging and none of this gentle stuff for the Absorption Stage are in the minority and looking at their bottom line, figure if we are that desparate, we will buy one of their adjustable voltage units they make. I did! Love it! Crank the knob to anything you like when you like! Wheee! :)
