This Curtis 1236SE-6521 is 48-80 V (operates up to 100 V input), at 450 A. It was purchased as a spare but never used. The seller didn't pack it very well causing the 35-pin connector to get broken. They offered a discount which I'm passing along. The 35-pin connector holds in pretty solid by itself, but some good silicone adhesive or something similar should be able to be used to hold the connector in place. I'll ship quickly for $30 anywhere in the lower 48.
