Re: [Electric Boats] Electrical 'efficiency' of batteries in my boat.

 

Matthew

Having the boat at your house certainly makes it convenient for charging. Unfortunately my boatyard does not allow any AC cords to be connected to the during winter storage unless you are onboard. I usually try and check on things once a week but, this winter was so bad I went only a few times to check on it. Having the solar panel and wind generator did not make it a problem. When I pluged in the ZIVAN NG-1 it dropped out of bulk charge within 30 seconds. Usually within an hour it had gone into the maintaining mode. Same thing happens when the boat is out on the mooring.

I don't have an external power socket, the boat is charged by putting
a power cord under my front door. One of these days I need to get an
external weather proof socket on the side of the house where the boat is
parked.

And the Delta-Q charger actually shuts off entirely when it's fully
charged, I assume if left powered, at regular intervals it would tickle
the batteries to keep em topped off.
