Solar Boat Suntiano.

Like Fritz and Matt I'm a huge fan of solar boating. Our boat Suntiano is solar powered. The boat was launched for the first time in 2014It evolved in a usable boat. We especially like to use it in Friesland (Northern part of the Netherlands).We use the boat like it is supposed to be used: as a recreation boat. It turned out to be a nice sailing picknick place, complete with fridge, running on free energy! How cool is that?! Even on a cloudy day it is able to keep up with other open boats. We…See More

Using used Lithium ion batteries (from Teslas, Leafs, Volts etc)

Used Lithium ion batteries from cars such as the Tesla, Leaf, and Volt are starting to show on Ebay and other web sites.  They cost about 1/2 the price of new lithium iron phosphate batteries, and so are tempting to those of us on a budget.  I have never been comfortable with the idea of using lithium ion batteries in a boat and have mentioned it in a number of discussion here.  I have just found a more detailed, and entertaining discussion, of the problems with these recycled battery packs on…See More

36v MotorGuide xi5 Voltage

I have a 36v MotorGuide xi5 trolling motor that I need to conform my calb72cam cells to.  Currently I use 16 cells to make my 48v nominal bank.  I've looked through all the documentation for this trolling motor but none of it seems to list the optimal voltage for running this motor.I intend so far to reduce the bank from 16 cells down to 12 cells.  12x3.2=38.4 volts.  Will this be sufficient for the motor or should I make the bank from 11 cells?See More

Intro, info, hello!

I am completely new to sailboats, but knew, if I wanted exotic, beach front living, that is what it was going to be. Last May, after 2 plus years of research, I bought my retirement!!! A 1972 Dufour Arpege...she is BEA utiful almost...I have completely gutted the inside and am giving her a completely new floor plan and everything else. I am going all electric, except a back up Honda generator! Solar panels, wind generator etc. I've done some research and like Aquion for my batteries, any…See More
