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

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!

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 :)
