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 18.5mmIt 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.
