Power supply with pencil battery (AA) - 4 x 1.5V batteries
Warning: Last items in stock!
Make your project portable with this power pack that accommodates 4 AA batteries. It accepts AA Alkaline or rechargeable batteries. There is a protective cover (which fits) and the case is equipped with a switch on/off very handy when your project does not yet have a switch.
The four batteries are connected in series, enough to produce a nominal voltage of 6 volts DC with Alkaline batteries (6.4V when they are brand new, 4V when they are exhausted). If you use rechargeable batteries, the nominal voltage will be 4.8 volts DC (5.2V when brand new, 4.4V when discharged).
Using rechargeable batteries will be perfect for use with most 5V projects, with Alkaline batteries, you can place a 1N4001 diode in series to reduce the voltage from 6V to 5.3V.
Battery not included.
If you buy a Jack plug (not included) it is relatively simple. The center of the plug must be positive and the outer part of the plug the ground (this is a standard).
