Powerbank box. 18650 Battery Arduino shield v.8
Description
With this board we can use 2 batteries of type 18650 and we can mount a powerbank that will offer us 1 USB port with up to 3Ah, 5 pins of 5v and 3Ah and another 5 pins with 3.3v and 1Ah with which we can power any IOT project based on Arduino , Raspberry Pi, ESP8266, etc. The batteries can be charged through a Micro USB port or a USB-C port. My design offers a box to house the set and dispose of it in a compact and easy-to-use format. I have used a translucent black methacrylate laser cut, for which I have engraved the name of the corresponding ports. In order to laser cut and engrave the board, I include an SVG file. In case you do not have a laser cutter, you can use the STL file that corresponds to the cover and print it in 3D.

I usually use high capacity batteries that offer continued use of projects. These are some of the batteries that I have found with greater capacity (https://www.ebay.com/sch/i.html?_from=R40&_trksid=m570.l1313&_nkw=18650+battery+9900mha&_sacat=0&LH_TitleDesc=0&_osacat=0&_odkw=18650+battery+shield+v8) Mounting: It is important to put on the inside of the box a piece of EVA rubber to fit the powerbank and press to prevent the batteries from leaking. The inserts must be placed carefully so that they are not misaligned with respect to the holes in the plate. Nylon nuts are used to press the plate down and the batteries stand firm. Hence, the four nuts must be placed on the screws, calculating what should be inserted in the inserts and the plate spacer (about 6mm).
