Hi! I'm fairly new with Arduino, and currently I still haven't memorised all of the possible power options for my projects. Recently I have been experimenting on 18650 powerpacks, some of them customized for non-arduino projects. I was wondering if my Arduino projects can be powered using a 18650 pack in a specific arrangement. I was wondering if there are any guides or diagrams for making a powerpack without having to involve a chip or an external circuit. I'm hoping to be able to power it with an arrangement similar to a 6x AA battery pack or a 9v battery adapter. Any help would be appreciated.
Also, if I am doing something wrong with this forum post, please tell me as I am not sure if I am doing it correctly.
