Power / Battery Holders / AAA

This battery holder connects 3 AAA batteries together in series for powering all kinds of projects. We spec'd these out because the box is slim, and 3 AAA's add up to about 3.3-4.5V, a very similar range to Lithium Ion/polymer (Li-Ion) batteries and have an on-off switch. That makes them ideal for use with 3.3V projects that have a 2-pin JST connector meant for one...

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 2 AAA's add 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 the output voltage will range from about 2.7V with...
