two small 2mm hex screws when you look down inside on the bottom edges you can see them
it moves the cage front to back a bit but does not make it go down deeper which for me is more the issue the height as the battery sits in from bottom to top is the same sadly
at least I did not see it change from top to bottom
the amount it misses by is small for me and I noticed the little cage thing that flips down has some raised edges I might just cut those down and see if that makes it easier which I think it will
my other idea was aluminum hood then take out that plastic thing that flips down and replace it with a small piece of CCF on the hood to keep the battery in there better

How do you adjust the battery tray?
