Drafty:
Don't use spade designs, PERIOD.
that PWM I was talking about, it was being used on a "WET-CELL" and I was trying to get things set to ONLY run at 20 Amps. I was in a learning stage with PWM's (still am for that matter).

I have since, basically abandoned the Wet-Cells, and concentrating my attention on DRY-CELLS. I am still dabbling on the wet cells, but that's not my main focus.

Basically put, as Phil put it, NO SPADES. I know I won't encounter that issue again. Too bad I didn't know it back then.

There are Plenty of ZERO's Replicas out there. As of Now, I know of none Better (Well, MAYBE Phils, but I'm not sure his "HULK" Is publically available YET)
Do the research, you'll find what you need.
