I'm running 2 12-volt batteries running in series to power my 24-volt
electric motor in my jon boat (on an electric-only reservoir) and I want to
run a fish finder. Here's my question -- can I safely run the fish finder
off of one of the 2 12-volt batteries while running the 24-volt motor? Or,
is that going to burn up the fish finder? Should I just invest in a couple
of 6-volt lantern batteries instead?
