While at OSH this year, I had several interesting conversations with the folks at EarthX battery. Their battery is LiFePO4. It produces way higher cold cranking amps and weighs only 4.8 lbs! Much better than the current Odyssey PC680 that is about 15.5 lbs. Had to change nutplate types to two of the single tail ones for their mounting box. It is a mirror finish. Looks nice! Was able to utilize the same holes in the firewall. Hopefully this has little effect on CG once I get that figured out.
