With the old Trojans the OBC would always shut off when charge was complete so OBC must be good. Voltage check after shutting off the charger is 8.7 on all batteries and 51.9 all together. Does the OBC need reprogramming or what?

Not an expert but I'm saying yes.

Need to find out the Algorithm for the Sams Club batteries as your charger is still set for the Trojans.

Once you find out who makes those batteries you can DL and install the proper setting.
