BMW under frame mounted Battery Box

This is a stainless steel battery box for BMW airhead 7 series. Being stainless steel you can paint it or leave it bare metal. The shape is designed to follow the angle of the oil pan to look more seamless.

It is a two piece design that hangs on engine frame mount and bolts to the transmission. It is designed to hold a Size 9 motorcycle battery.

We offer an option to include a gel or lithium battery with the battery box. With the lithium battery you can basically drop almost 20 lbs and whats left is under the motor for serious corner carving.

Battery stats:

Lithium: YTX9-BS, LiFePo4 12v/8ah/210cca, 1 lb

Gel: YTX9-BS, AGM 12v/8ah/120cca, 7 lbs

PLEASE NOTE: This modification requires eliminating any exhaust cross over pipe or center stand that occupies this space.
