This battery holder takes 4x AA cells (standard or rechargeable AA batteries) and features a clip-on cover - great for robotics projects!
The holder usually outputs between 4.8V-6V depending on the batteries used and their level of charge. An on/off switch is included on the lid for convenient power control.
The wires are finished with standard 0.1" male headers for use on a breadboard or similar, however these can be snipped off for wiring to terminals or soldering.
Note: Don't plug this directly into a 5V microcontroller without regulating the voltage!
