This is an extremely tiny and light weight battery based on the new Polymer Lithium Ion chemistry. This is the highest energy density currently in production. Each cells outputs a nominal 3.7V at 20mAh. This may sound small, but the cell is less than an inch square!

Comes terminated with a standard 2-pin JST-PH connector - 2mm spacing between pins. These batteries require special charging. Do not attempt to charge these with anything but a specialized Lithium Polymer charger. Battery includes built-in protection against over voltage, over current, and minimum voltage.

Note: Be careful with the JST connectors. They can stick in pretty good and tugging on them can damage the connector. Check this tutorial for an easy way to remove them safely.

This is a simple 4 cell AA battery holder. The 5 inch cable is terminated with a standard 5.5x2.1mm, center positive barrel jack connector.

The connector mates with the barrel jack on the Arduino (among a number of other products) allowing you to easily make your project battery powered.

Note: the average voltage regulator has about 1V of dropout (but can vary greatly). This pack, with normal alkaline batteries, will output ~5.5V causing a normal 5V board to run at around 4 to 4.5V. This depends a lot of what board and processor you are using with the battery pack. Please consult yer datasheet.

This 2xAA battery holder puts a nice finishing touch on your battery powered project. This holder features a removable, sliding cover, which is secured with a small Phillips head screw. Another bonus is the ON/OFF switch which can be used to control power to your project.

The leads are about 150mm and are terminated with a JST connector.
