I'm a fan.
Sounds impressive and I.m interested. I made a couple of these years ago from plans on the internet. They worked on batteries being stored but they did not come out "marine grade" so I never but them aboard.
The website did not make it clear that they only worked while charging as you did above so that answers one question... The other is, do they interfere with any of your electronics?
