Description:

This battery box is from N-Tech Engineering and was part of their BMK (Battery Miniaturization Kit).  It includes the box itself and the hold-down strap from the kit.  Does not include battery. 

This mounts in place of the stock battery and uses existing bolt holes (and bolts) so no drilling required.  The factory battery positive cable works just fine with this (some other types of smaller batteries don't reach since a fuse box is integrated with the positive connection).  It is maybe a half hour of work to swap out the factory battery and tray and only needs basic hand tools. 

The box is in good condition with minor surface scuffing in a few spots. 

The smaller batteries are used for adding larger intercoolers (but check the size of whatever you are installing to make sure this will fit with it).
