Yeah, that battery box is nice, even if it is so oddly colored!
I don't use many non-Lego parts, but ... (deadly hush from all true Lego
purists)
I have rejected the Lego rubber catapillar treads. They don't work for me
and they're
too small. I have scavenged much large ones from Tonka dozers and other large
scale tanks etc. They enable you to build much larger bases to carry more
stuff.
And being able to use large wheels with a nice length of "up slope" at the
front and
rear of the tread gives superior deep pile handling. As well as doorway
sills etc.
but,
they take more horse power too. So, using extra battery boxes like the one in
3591, you can easily build an RCX booster brick to run multiple motors in
parallel.
I use three per tread, matched beforehand for same speed at same voltage. The
booster scheme gives you much better battery life in the RCX and it's a
piece of
cake to pop out the battery box and be able to replace just the motor drive
batteries.
All in all, I think this Znap sale is a real boon. Lots of motors and lots
of battery
packs to power them with!
