This is the same 18650 Lithium Ion Cell that you know and love, but now includes pre-attached solder tabs! These round high capacity cells have bee...

The tiny little LiPo/LiIon power supply shim for all versions of the Raspberry Pi!We love mobile projects but having a discrete, slick, and tidy po...

Is there anything an Arduino can’t do? Well, for one, most of them can’t be powered directly from a 3.7V LiPo battery; much less charge and monitor...

This product is a 3-in-1 cable. By itself, it can act as an extension cord for any 5.5/2.1mm DC power cable. The heavy 24 AWG wires can handle up t...

This is a very simple board that takes a 4-9V input voltage and outputs a selectable 1.8V or 3.3V regulated voltage. All headers are 0.1" pitch for...

A Difficult Choice Made Easy The choice of LiPo batteries and battery chargers can be overwhelming. In the past, with older RC cars and NiCd ba...
