got the "generic" 150x50mm tray and it fits great in my Hyper 7 conversion. My 5s 4000 40c lipo fits like a glove lying flat in this thing. Could not be happier. Definitely would buy again.

I cant say enough good things about Mikes quality of talent.

These trays will securely hold your lipo sand protect it from damage, after many crashes my lipos are all fine and my trays are un damaged. New tray with esc shelf really makes me feel better knowing my MMM is securely mounted in my truggy

I've used a few of Mike's battery trays and have never had a problem. They are plenty strong and always the right size.

got one of these for my xt8 and this thing is THICK, and the fit was absolutely perfect! i just had to let mike know what batteries i was running and the xt8, and he figured it all out. 2 years now and not a single issue - and i beat the snot out of it! THANKS MIKE!!!

These trays are a must for any complete conversion. The ability to get so many different sizes and shapes along with the custom option makes the possibilities endless. Well made and strong the perfect protection for high end lipos and such. Highly recommended!
