Re: Amel is going lithium

Really interesting thread, thank you. We are following with interest.
After we met you at the Caribbean Amel Rally 2019 we took a late decision to do the Pacific this year, and end our circumnavigation in Nov 2019 instead of 2010. After this, we will probably sell Island Pearl II, but if we do not sell and decide to go around again instead, then adding Lithium batteries will certainly be the last of many upgrade steps to Island Pearl II. Based on this I would also be most interested in getting a copy of your upcoming Lithium report.
On Island Pearl II we have 1040w of solar, run through three separate solar controllers, plus two Rutland 1200 wind gens, and we now seldom use the genset. We have the same 100 Duo watermaker as you, plus do all cooking on our induction stove which is so much nicer than gas cooking. Gas is only for oven baking which we seldom do. To improve washing efficiency we recently upgraded the Amel supplied "Thompson" washing machine to a new "Bosch" as that comes with better cleaning and efficiency, and particularly has a dedicated special "cold water" washing cycle for doing our washing from batteries only.
As we near the end of our circumnavigation, we are now pretty close to running the boat "off the grid", but I have always thought that the final piece to the puzzle would be Lithium batteries, so look forward to reading your article and learning from your experiences.
By the way, in addition, I remain a total convert to the need for at least two good wind generators on any boat in order to reach a total off the grid experience. Litium could become the trup card that proves me wrong on this but I doubt it. These units are so now so quiet, that (other than visually) they go almost unnoticed. When one considers 50% of time is in darkness, and at least another 5% each per early morning and late afternoon low sun angle, leaves only 40% max (and that is on a sunny day!) with good solar production. Yes solar output completely outstrips that of wind power ten times over, but we would never again be without at least two latest models, high-efficiency good quality wind gen units aswell, which, for example, on night crossings on a beam reach, I often watch putting out 6amp each constantly, and then at anchor on cloudy/windy days (27 - 33kts) push out over 10amps each (x24v of course).
Watching with interest
