Battery Holder Cell Box with DC Jack (2 x 18650)


This is a 2 cell 18650 battery holder terminated with a standard 2.1mm DC Barrel Jack. Connect two 18650 batteries in series so the output voltage is rated at 7.4V (2 x 3.7V). This voltage is pretty good for Arduino that comes with a 5V or 3.3V voltage regulator. Of course not to forget all IoT and Robotic projects.
