If you already have a small battery and just need the mounting kit here is the perfect solution. Designed around the Hawker PC680 battery, the mounting bracket is CNC waterjet cut from 1/8" thick aluminum and utilizes 3 mounting points. The battery tray is CNC machined from 1/2" thick aluminum then TIG welded to the mounting bracket to hold everything in place. To top it off the battery tie down is CNC machined from 1/2" thick aluminum and is engraved with the JMF logo. The tie down is polished to a mirror finish at no extra cost to you.
