How do you charge your cells? I’m hoping to have solar, shore power and alternator charging, just for redundancy and boosting the charging amps.

Simi, sincere thanks for posting this, and I have signed up to that forum, too. I have a project planned for our new boat, based around 2 x 440W Canadian panels, and those batteries you linked to sound perfect for this.




We think 450–500ah will be more than sufficient; will start a thread on this when we begin. Thanks again!

I have found the actual Watts produced to be 25-50%, depends on time of year shading , angle of panels. My advice: put as many of the largest panels you can buy. I have 4 380 watts. Max I could find a few years ago.
