double batteries..

[Jimmy B]

not sure if this si a good place to post or not..

to hook up 2 batteries for more power, can i just run an extra power/ground line between the 2 batteries?

i need to put an extra one in the boat for the ststem, i was jsut wondering if that was the way to do it or not...

and if i want to disconnect one to save it to start the boat can i jsut dissconnect the positive side?

if anyone knows let me know, thanks!!!

That should work but I would remove both cables to be sure. Do boats have alternators?

[gobraves00]

put circuit breakers on the power wires going to the batteries and just flip them of when not in use

you need a battery isolator.
