This battery holder connects 2 AAA batteries together in series for powering all kinds of projects. We spec'd these out because the box is nicely slim, and 2x 1.5V AAA adds up to about 3V for low-voltage electronics projects, plus it has a nifty on-off switch.
Fits any standard AAA battery. When using rechargeable NiMH batteries you'll see ~2.4V output, or use with 1.5V alkaline cells for ~3V output.
The polarity matches that of our 2-pin JST cable and Li-Ion/Poly batteries. Uses a JST-PH connector so it won't 'catch and tear' in JST connectors.
This is a great option for the micro:bit because it has an on-off switch built in so you don't have to yank it out to turn off the power.
- Cable Length: 6" long, terminated with a JST-PH 2 pin connector
