oh, those voltage spikes make me real mad!

Thank you everyone! There are now about 2.2 out of 10 mosfets sponsored! I'm going to learn as much as I can about how not to make these cheap ones fail so I don't leave a man behind!

Update: I'm hooking up the Hall Effect current sensor, even though it did get pretty dang hot on an earlier soldering attempt. Assuming it isn't barbecued, I will get a good idea about how much current each mosfet can handle. I'll program it to limit current to 5 and then 10, 15, 20, etc... until it dies???? hmm... that seems a bit harsh. I'll do something similar on the car's version, even though Ian's results with those 200v mosfets says they can handle about 50 amps continuous. It would be good to know for sure in my case, I guess.
