SK150S housing for Makita

I needed adjustable psu for makita battery, didn't like any of the models here, so I made my own.

I used SK150S from aliexpress, I like it because it has step down and boost option and plenty of amperage.

I designed the housing so that it can be powered through Makita battery by default but I can also switch off the battery with KCD1 switch and I can power it up from side XT60 switch, which would be useful for any longterm applications that would otherwise drain my battery.

I use additional 30mm fan for cooling. 

I used makita battery mount from aliexpress, which screws into my printed housing, its much better than printing mount myself.

Wiring is easier with soft silicone.
