Ah, now you see, this is another good case, of I didn't know that. I thought because these beasts were 36V, which is not standard, that there were no charge controllers for it. I thought they were are geared fro 12, 24 or 48V.
Now the question is does it handle all of the conditions? Does it have a failsafe? I'm looking it up, but I'm not seeing right away what the specifics are...

Subj: (ET) Re Inventing the Wheel
"We need to find an 'inspired' Microcontroller Engineer (meaning EE & CS
skills) who wants to design PIC (or similar) microcontroller into a charge controller with real time clock, alarm (piezo buzzer, etc), voltage readout, and maybe temperature and current monitoring. [adding more features adds some cost in hardware, and tedious software testing]
I know bits and pieces of this (strong enough in hardware part), but am far too weak in C or Assembly language programming to get it done in timely manner.
Maybe we could form an 'Open Source' team to design this - similar to the project for PWM motor controllers called OSMC (Open Source Motor Controller).
In that case, a few guys collaborated on electrical hardware and software design for a microprocessor controlled, Pulse Width Modulated DC motor controller, for hobby Robotics competition."
