Installed myself in Scotts Valley. Cut the panels. Hardest part was finding large Torx bits for the larger fasteners (took a couple of auto parts store trips to find).
I converted my Newport 33 sailboat to electric four years ago (while waiting for my R1T). Removed the diesel engine and fuel tank and installed Electric Yacht 10kw motor and two 48V LiFePO4 battery banks (Battle Borne). Replaced 12V ship power with 200Ah Dakota Lithium. Quietest boat in the harbor!
