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...

"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."
