The new chargers are in!

Some testing revealed that they work exactly like I want them to. They bulk charge to 14.7-14.8V, absorption for about half an hour at this voltage, and then float at 13.6-13.7V. I measured them to be 75% efficient no matter what output current/voltage is at.

I tied pairs together as "charger stacks". One stack is behind each seat and the other stack is on my control board under the hood.

And here is a picture of something that I have yet to do with any of my chargers so far:

Float charge. Probably something that most other EV owners take for granted. I left them on float for about five hours to make sure the batteries were fully saturated and extra happy (for once).

Now it charges up in less than half the time of my Mastercraft chargers because the current does not slow down as the battery voltage and resistance rises. Finally! A charging solution that works!
