I had some Digital Voltimeter laying around, so i decided to make a quick box to make a simple 1s lipo checker for my Micro Drones / Whoops.

I'm using one of these Voltimeter checkers:

Solder a male ph2.0 or BT2.0 conector to the voltimeter and add a drop of hot glue to fix the 3dprinted parts and you are done.

Advice:
Don't choose the green one its difficult to read in some bright light conditions. The red color is easier to read.
