Crap, just remembered you asked me that on Facebook and I completely forgot to reply

I don't think you'd kill the Scorpion XL, mainly because the speedo has current limiting built in. With my XL in Drumroll II, whenever I slammed the stick full forwards, the wheels would spin almost to full speed but then cut out, which I believe was the current limiting kicking in temporarily; I'd have to either then bring the stick back a little or ramp the speed up gradually to get around the issue (never was much of an issue in battle though).

So if you were to run the golds on 24V and they ended up drawing too much current, the motors would (should!) just cut out to protect the speedo.

One thing to possibly watch out for though is that the Scorpion's max input voltage is 28V, but a fully-charged 24V battery pack will be nearer to the 30V mark, so that might cause an issue. A similar thing happened to Gary using the Sabretooth. He was running two 18V drill motors at 24V and let the magic smoke out of two units before reverting to Electronizes. The increased current draw from the motors as a result of overvolting, as well as the high voltage of a fully-charged 24V pack were most likely the reasons for the failures.
