Re: Tank Track
We run two robots using 5 motors and a servo each we brought 2 power packs and two spare 7.2V batteries plus one spare 9.6V (you wouldn't really need the spare 9.6V one (we haven't had to use it at a competition yet) so really it would cost you US$140 for enough batteries for the competitions here plus the input into the charger is quite a big range something like 7-14V (don't quote me on this though i will edit the post once i have checked in a few minutes) Symbiohsis has gotten away with four robot batteries two transmitter batteries and one charger (the charger will only charge one battery at a time though even though it holds four  ) for the last competition and we seem to have done okay 
Sorry 11-20V dc input into the chargers (grab a 2A 12V power supply from jaycar for about $40 and wire the two chargers into one power supply - outlets are limited at competitions.
