I gave up the upside down mounting because it didn’t work with all the wires in the end.
Used some bushings from penny trucks as stand-offs
Then yesterday I managed to short the battery with an aluminium plate, here more info about the fireworks.
had to cut the wires and solder new extensions but this time a XT90S so no more loopkey as well.
For safety I used some tape on all bullet connectors and to hold the wires in place.
I found 3 different metal lids at home 
today I was riding with the red one
I was riding quite hard and when I came back home I touched the vescs and they were cool, very funny. Unfortunately dust is everywhere so this open enclosure makes no sense even in good weather.
