Updates Nov 2021 Added version with 6W LED light removed, found it was not very bright or useful.
Also added a version with second XT60 connector, moved 48W LED mount to center of top. Added version with no 48W LED mount, no holes in top if you don't want LED light or want to drill holes to mount your own type of LED light.
