Another way to set up a dual voltage system would be to use relays to
switch the batteries from parallel to series.  You could run at low speed
with the batteries in parallel, drawing less current from each battery.
Switching to high speed puts the batteries in series, giving you double
the voltage but less runtime.


I'm interested in the hobby, and have been following the discussion here
closely.  Unfortunately, I don't have the money, time, or space to devote
to building a tank right now.  Eventually I hope to have all three and be
able to join you on the battlefield, but for now I'll simply lurk and
learn.
