I needed a portable battery cradle for something I'm working on, couldn't find one so made this one myself.
Total length is 151.5mm, total width is 113.5mm ans depth is 18.5mm
It will fit a battery size of 150mm x 75mm x 18mm or smaller it will fit a slightly longer one as it has an open end.
Provision for 4 x 3.5mm screws has been made.
