The solar box

You can find this cases on well know portal with a name starting with "A", they are usually called "solar charger for 18650" , or "camera charging", etc. The box is build of black plastic, has a decent solar panel, and a place to install 6x18650 lipo batteries. The box will also have charging board. They are also weather resistant. I didn`t have any issues with it, even though the oldest boxes are in use for about 6 months. This boxes can be found for 16-20 Euro

3D printed parts & power botton

This is what you should get in the parcel:
  • box

  • power adapters

  • feet

  • manual

Disasembly
  • open the box - 8 screws

  • remove the external cable - 1 screw

  • unscrew the charging board and remove it = 1 screw + 1 plug

Remove plastic parts

this is the box before and after,

you need to remove some plastic to fit the board and power cables. you wil have to dril the holes, to install antena adapter, safety ring, and power button.

Remer to make some space for the pigtail!

Don`t pinch it when closing the box!

Cut the battery pads

leave a little extra at the end for soldering the power wires

Solder the wires with the ferrite cores

Assemble, pcb, power cables, pigtail, antena and test everything

If there is no fire, no smoke, and you are able to log on the pcb and send some adverts, it means that it probably it works and you can go outside and install it :)
