#Lithium ion accumulators damn not stable. Do not build it if you do not understand what is happening. All responsibility on you. Do not carry on the plane! Thick body for isolation from solar energy. Use an additional layer of insulation with aluminum foil from the side of the solar element. Using suitable BMS 3S to charge batteries included sequentially. Do not leave unattended while charging from the sun. Do not allow over-heating. For the manufacture of the upper shell, use only white ABS material. I have not thought up which devices I will put instead of temporary toolbars. You can set them yourself. I use as a power source for 12V soldering iron. On the sidebar Power off button, 2 USB ports (5V via Stepdown) and 12V charge connector.
