XH-M609 HCW-M635 Low voltage disconnect solid case

2025/12/07 update:

I've added a case with cutout for KCD11 button to cutout input power. This was created because in cutoff state it would still be drawing some current for the internal converter, relay and display which is not optimal when the battery is already low.

After some testing, the module didn't generate much heat and I was going to use it in dusty environment hence this remix.

Photo 2 and 3 are to show what bottom with horizontal and vertical tabs are like.

Changes:

• Filled up all ventilation holes

• Added “Plus” and “Minus” labels for the buttons

• Added chamfer to screw holes so the print don't need support anymore
