Max voltage is around 17v Best voltage is around 7.2v
Personally I use a 7.4v LiPo which is 8.4v fully charged, the onboard regulators do their job very well and the 6v voltage regulator I added to the battery powers the h-bridge and 6v servos nicely.
It depends what else you run in the robot, some use 12v so they can also power a netbook or mini itx board.
But for a Wall-e, you will be restricted for space so I'd say look for a good NiMh or NiCd battery pack to supply 6-7.2v or small LiPo LiIon. The main problem you will run in to though is battery life...
You could always build Wall-e's toolbox he carries and fill it with batteries though
The power adapter plugs in to the EZB and has 2 terminals for you to connect your battery to. So the battery could be anything really (just snip off the plug that comes on it if it has one - do one wire at a time otherwise you will short it out).
But as DJ said, you get a battery holder with the kit that holds 6 batteries. 6 x 1.5v AA cells = 9v or 6 x 1.2v NiCd AA cells = 7.2v Charging could be using a standard AA battery charger (get yourself a few sets of batteries so you never have to wait around for them to charge)

How would the battery charge? through the ez-b attachment? or do i need to get one with stray wires at the ends and a charging cable.
Or what type of battery adapter comes with ez kit?
What is this?
Do i have to get a battery with this end if i want extra power for longer battery life but still be able to charge using a charger compadible?
