i want to control multiple servos and sensors (6-8 ports) with the ez-b
i don't planning on running it for more than about half an hour
and only have two options to choose from for the battery
should i take 12v 5amps or
6v 7amps
JSTARNE1 -- don't have many supplies, so i can't break/separate the wires to power directly (have to power it from the ez-b) ---- thanks for the info though, maybe in future projects

The first battery 6v 4.5 ah fits your budget well and should give you the runtime.if not close.to a hour running 6 servos. It is 11 dollars shipped and model number is.ub645
Quick question on these batteries. How would one go about charging them? Can you recommend a charger to with them?
Many thanks
Matt

If you are handy with a soldering iron and don't mind modifying your board (NOTE: no warranty if you make a mistake!) there is an another option to get external power feeding into some of the digital ports (D0 - D14). Check out what I did to accommodate that. External power mod
You only need to cut the trace and supply 6v to the EXT PWR inputs (beside D14)... the jumper option is optional so I could go back and forth between external and internal power (Never try both with jumper in place :))
