5 x AA Battery Holder with 2.1mm DC Jack
Here's yet another addition to our family of AA battery holders. It's a holder for five AA batteries with 5" wire leads. It's black and has a 2.1mm barrel plug (tip positive).
5 x AA battery packs are best used with Arduino-compatibles and other dev boards with 2.1mm DC jacks and a 5V regulator, because 5V regulators tend to like 1-2V of overhead.
4xAA battery holders give you ~7.5V when used with 1.5V alkaline cells, or around 6V when using NiMH rechargeable cells (6V is just a tiny bit too low for Arduino boards).
This 5xAA holder is just big enough to fit on our robot rover kits, and power both an Arduino-compatible and a couple of motors.
