We've been happy enough with our Lithium Iron Phosphate (LiFePO4) battery installation that I volunteered to do a presentation at the Annapolis Sail & Power Squadron meeting, Sept 1, 2016.

I later did a revised version of the talk to the Marine Trawler Owner's Association. This version contains a few more details. It is 29.2MB.
