2 x AAA Battery Holder with switch

This handy battery holder features a power switch and a JST connector. It connects two AAA batteries in series, and its compact size makes it perfect for portable projects. This is the same battery holder used in our well - known micro:bit accessories kit. Key features include: holds two AAA batteries (not included), JST connector compatible with micro:bit, a power switch, and dimensions of 63x26x16mm excluding the cable.

Using this battery holder is easy. First, open the holder and insert two AAA batteries (you'll need to get these separately). Connect the JST connector to your micro:bit or other compatible device. To turn the power on or off, simply use the power switch. When not in use, keep the battery holder in a dry and cool place. If you notice any issues with the power connection, check the battery installation and the JST connector. Avoid exposing the battery holder to water or extreme temperatures to maintain its performance.
