They draw 7amps each. What kind of battery do I need for
a full day of fishing ? Would a portable power pack (33 ah deep cycle)
work


They probably only draw 7 amps when you are hauling them in. (Unless
you're running some hot wire, fish attracting setup).

Let's say you haul the downrigger up for as many as
10 minutes in an hour.......

If my math is right you're using 1/6 of 7 ah.That's not a lot of
electricity
