Randy does have a clue for sure, but not all Boondockers are the same. Mex probably means the adjustable voltage ones. The regular ones get the batteries to 14.6 and then drop to 13.6 for the rest of the recharge.
This is not very good for generator charging, but most people are on shore power and also there is an idea out there among many that they want to be "gentle" with the batteries. The customer is always right! :(
Years ago Randy was posting how you could get to the internal pot of a Paramode and adjust the voltage. He said guys in the desert were doing that. He and the PowerMax guys have been looking at ways to make it easier to adjust the PowerMax too without having to open it up and get at the tiny little internal pot.
They finally got onto this external knob idea as with my prototype from early 2012. PM has had that as an option on their PMBCs ever since and Randy now has his own version.
One of my ugly graphs shows the regular PM charging profile and time taken compared with adjusting the absorption voltage so it stays at 14.6 instead of dropping to 13.6. it also has some Vector graphs in there so it is "busy" but work real hard and you can get all the info :)
