Hi all, I've been poking around in the forums
reading about how best to power a laptop
aboard. I know my laptop
runs on 19 volts, and I'd say 18 volts is close enough to run it, plus I can charge my 18 volt power tools off an 18 volt system, and it seems like an 18 volt system should be attainable by putting a 6 volt golf cart battery
in series with a 12 volt car/marine battery
. Plus, two 6 volt golf cart batteries in parallel should be able to charge off the same systems that charge my current
12 volt system.
So, I envision a 2 marine
battery(12v) and 2 golf cart battery(6v) system that will allow me to power my 18v appliances(computer, drill etc) with an auxillary 18v line, yet with minimal changes to the 12v infrastructure of my boat because of the ability to charge the two 6v batteries(when in parallel connection) with my 12v charging
system, and because the "main line" will still be 12v.
My question: How do I wire the 4 batteries together to make it all work(without playing battery musical chair)!
