This battery case holds 2 AA batteries and connects them together in series. The case fully encloses the batteries and features a simple On/Off switch. The output voltage with 2 standard AA batteries will be approximately 3VDC. The case has 6” wire leads, red being positive and black being negative, terminated in a JST-XH connector. This connector is larger than the JST-PH found on the micro:bit, Arduino Pro, and other boards.

There are no mounting holes on this case but a good double sided tape could be used on the smooth back to attach it to your project.
