See Azimov, this is what i was afraid of.

Hey! Don't blame me for this misconception. I let you win that little debate in another thread because nit picky arguing in these sterile forums is very unproductive.
People make a very common layman's mistake of lumping voltage and current into one thing they think of as power. They don't understand the universe of the electron but they are very interested in the effects of the mods. My approach was to simplify the explination so they can proceed with their modding ideas. I already stated I won't do that anymore. You're approach is to transcript theory and text from a manual. That doesn't work either cause the interest isn't in the electronics theory or our knowledge of it, it's about getting the mod done and getting it right so we can all gawk at the cool pictures. Accuracy is important, but brevity is divine.
Now, If we are past the point of who's well read and who ain't, I would suggest a transister on a seperate board that would switch power from another battery supply directly to the motor. A mini relay so to speak. I've seen this done before and it works, but I wonder why you need it.
Speed I mean. Why do you need it in a 4 wheel drive, balloon tired, super high center of gravity, monster truck. These things are made to be geared down, slower and torquer. In this sense, the SE boards would work fine in conjunction with higher grade motors. Yes, you can do it with super efficient motors. But, it's silly to buy them as they are very expensive. The solution is to find them in scrapped electronics. The ejector motor on a Playstation1 is a prime example. Gearing gets you where you need to be and the lower duty cycle means you can crawl the obstacle course longer.
Nah, don't do that. Look at it some more and research others solutions and ask questions.

I guess if you are into BEAM robotics, you would understand.

I understand very well, but consider this. When Mark Tilden created Walkman, his famous walker, he preached the precepts of BEAM as creating very capable robots from salvagable parts. Therefore making cheap, robust robotics available to anyone. But, what he doesn't mention (though it's not like it's a secret) the Walkman motors he used cost 600.00 apiece and the thing has 4 of em. See, he's talkin techno scrap walkman motors fished outta dumpsters savin the world in so many ways, but he's building his marvelous machines on a government research budget. Well, he was. Now he makes toys at Hasbro. Which is what some have said he made all along. Point is, simplicity and cost are primary concerns in any project. But, to get something amazing, sometimes, you have to pay the cost.
EDIT: Oh, and just to destroy my stated stance on brevity even more, I just remembered a related tidbit of news. If I may be so bold as to toot my own horn a bit, I just found out that one of my BEAM robots has turned up in an article in Make magazine on newstands this month. No biggie I know, but I couldn't help feeling like Steve Martin in the movie "The Jerk" when he got a copy of the new phone book.
