This is a high capacity battery tray that was designed to hold an 8,000mah battery. I mostly trail, so need lots of capacity! I also designed the cover because I use a half-cab, but still wanted the battery to be protected. I just used a long M3 screw and lock nut to attach the cover to the tray. I also added velcro to the batteries and the tray just so it doesn't knock around in there.

I use the Ovonic battery linked below
