If you already have a small battery and just need the mounting kit, we offer that as well. Designed around the Hawker PC680 battery, the mounting bracket is CNC machined 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. This will fit the Hawker PC680 battery, as well as other batteries with the same dimensions.
