3 x AAA Battery Holder with On/Off Switch, JST, and Belt Clip

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 3x AAA batteries add up to about 3.3-4.5V, a very similar range to Lithium Ion/polymer (Li-Ion) batteries, plus it has a nifty on-off switch. That makes them ideal for use with 3.3V projects that have a 2-pin JST connector meant for one of our Li-Ion/Poly batteries (of course, you can't recharge them like Li-Ion/Polys, so don't try to plug this into one of our Li-Ion/Poly charger boards!).

It also features an ergonomic belt clip for taking your power on the go.

Fits any standard AAA battery. When using rechargeable NiMH batteries you'll see ~3.6V output, or use with 1.5V alkaline cells for ~4.5V 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.
