This battery case holds 4 AA batteries and connects them together in series. The output voltage with 4 standard AA batteries will be approximately 6VDC. The case has 220mm / 9” wire leads with a 2.1 x 5.5mm DC Barrel Jack on the end. These are ideal for use with the SparkFun moto:bit and are also compatible with our Panel Mount and Breadboard Friendly DC Barrel Jacks.

There are 4 mounting holes on the case for attaching it to your project; alternatively a good double sided tape could be used on the smooth back.
