These are very slim, extremely light weight batteries based on the new Polymer Lithium Ion chemistry. This is the highest energy density currently in production.  Comes terminated with a standard 2-pin JST-PH connector - 2mm spacing between pins...

This is a 5V DC 4A wall adapter power supply for LinkSprite Arches (was called pcDuino8). Its input is 100V to 240V AC.  Its output has a dimension of 4.0x1.7mm and center positive.

When we want to design Raspberry Pi into a real product, we often come into situation where the system can only provide a single voltage, for example, 24V. This DC to DC step down module addresses the problem by allowing a single external system power...

Li-ion Charger 1000mA, 8.5V  The LED will be red when charging and turn green when charging is done.

Packaged solar cell.   This unit is rated for 8V open voltage and 100mA short circuit (9V, 1W) Termination is soldering pads. Unit has a clear epoxy resin coating with hard-board backing. Robust sealing for out door applications!

High quality switching 'wall wart' AC to DC 5V 3000mA wall power supply. These are switch mode power supplies which mean the output is regulated to 5V (no more 14V outputs!) and the capable output current is much higher (3000mA!). Please note, this...

This handy multi-cell lithium ion battery meter can be used to monitor each cell of a multi-cell lithium ion battery pack over discharge. It will display the voltage of each cell, and the overall pack. The connector is -, 1, 2, 3, 4, 5, 6 (+) of each...

 If you need to charge LiPo batteries, this simple charger will do just that, and do it fast! The USB LiPo Charger is a basic charging circuit that allows you to charge 3.7V LiPo cells at a rate of 500mA or 100mA per hour. It is designed to charge...
