4 x AA Battery Holder with 2.1mm Plug

Here's another addition to our growing family of AA battery holders. A holder for 4 AA batteries! It's got an 8" long power cable with a 2.1mm DC jack at the end, and, oh yes, it's in classy Adafruit black. 4xAA battery packs are best used with development boards with 2.1mm DC jacks and can run with ~4.8V (4 x NiMH) to ~6V (4 x Alkaline). Great for powering boards with a ~4.5-6.5V DC input allowance as you'll see that range depending on how fresh the batteries are. DC plug is 5.5mm OD, 2.1mm ID with centre-positive polarity.
