Solar controller box 12v 12Ah

I'm grateful to describe my solar controller box. The idea of this project is to have a place for AGM battery and solar charge controller connected to the solar panel, that can create some DIY powerbank to supply 12v / 5v. The box is designed to fit AGM 12v 12Ah battery (151x98x95mm) and some cheap, popular solar charge controller. The holes spacing for the controller is 126 x 50 mm. All the holes in the box needs to be threaded with screws that will be usedto mount the controller and the cover. For the controller i used some speaker screws (the hole has 8mm x 2,5mm), and for the box cover I used popular PC fan screws that any PC owner should have. The box needs the supports only for the cable hole.
