John's 1976 VW with sunroof - SOLD
                                                     
  This is a conversion kit from KTA, 8" ADC motor, Curtis  controller, K&W battery charger, dc to dc converter 96 volts, potbox, amp and volt meters, and a state of charge gage. 

I've run out of time and money and my HOA wants it out of my driveway. This baby needs to be finished up. Brakes need adjusting, the front ones drag a little and the wheel bearing could use repacking or replacing as it doesn't roll as easily as it should. Car runs and shifts well, have had it up to 50 mph but don't know the true range yet due to the dragging. Passenger seat needs work. Some surface rust on floor no holes, a few rust bumps on the sunroof which will need a new locking mechanism and gasket as it leaks. Clear title and lic in AZ for alternative fuel plate. I was building it for a friend who went on a trip instead of getting the car. Just want my investment back and it out of my driveway. Email any questions or come by to see it.

  The rear showing-

at the bottom is the 8" ADC motor

the Curtis controller sitting on a platform, to the left is an Anderson 350 amp double connector that disconnects the battery pack.

at the top on the right is a Heinemann Circuit Breaker, next to it is a shunt for battery amps, on the left is the Albright contactor.

  The K&W charger, see the green led glowing...

 

The relay is a safety feature so that when the charger is energized the contactor cannot close.

  3 of the 12 volt Trojan's up front in a custom made battery rack. The other 5 12 V batteries are in the back, behind the rear seat.

As you can see the spare tire fits in also.

You can also see some of the 24 batteries, 4 in front and 20 in back..

 
 

   
  Here is another view of the front.

The grey box on the left has the contactors and circuit breaker in it.
 
 

   
  Here are the other 20 batteries. They are enclosed in a box. The little square hole you see is a muffin fan that goes on when the charger is on.

Steve is doing an S-10 also. We'll get some pictures of his progress up soon.
 
 

Here are some Excel sheets that I am working on, hopefully I'll get them to a point where you can plug in your own numbers...

 CHARGING - Perform an over charging maintenance cycle to the battery pack once every 10 days, or every 10 cycles, at about 4 amps for about 2 hours. This will gas enough to mix the electrolyte, and bring the pack to a full charge
