Thank you for the information, and good ideas Benm! While I have a few power diodes laying around that can certainly do the trick, they get hot regardless. I took your advice and picked up a nice little p-channel mosfet. Its forward resistance is almost zero, it's voltage drop is close...

I just got a really nice email from DTR's Laser Shop. He explained that the driver doesn't have a reverse protection (blocking) diode in order to maximize the run time from the batteries (and because it is so tiny, there isn't room for more components on the board.) This makes sense, but...

Thank you Garoq. I don't think it is one of yours. I purchased it from DTR, and it really was a great driver otherwise! It is (was) a 4A Super X-Drive(SXD-V3). I've read a few posts, after the fact, warning not to reverse polarity on the input. But how many times have we all put batteries...

So, I just fried my driver, too. I'm pissed at myself, because it was a careless accident, putting the batteries in backwards. But I'm also pissed that a $26 driver doesn't have a built-in reverse polarity protection for itself. It only takes one diode -a single $.02 diode. Anyone...
