Hi Allan,
Just wanted to throw in my two cents on Tesla battery comment.
Telsa batteries are the most energy dense commercially available battery on the market today, twice as energy dense as lifepo4. Packing all that energy in such a small space, makes them inherently much more volatile. Furthermore, the cell chemistry is much less stable than lifepo4. Handled properly they are incredibly safe, but a DIY boat setup is challenging.
I wouldn't think twice about building an EV with Tesla batteries or even a dinghy, but a cruising boat, potentially miles from shore is another story.
With that being said, I believe are EV batteries are going to be a game changer for electric boats and DIY'ers. One day, it will be plug and play.

Larry, since you have been experimenting with Li battery cells, what are your thoughts of using packs of the 18650 cells, as found packaged in some of the EV cars, such as the Tesla? There seems to be a high supply of used EV batteries on the market, some of the in 24V packs with BMS. For those of us not wanting to solder, weld, and package our own, are these worth the cost and weight?
