As tacmik said, I constantly run my bait tank, with a 6v 12a you should easily get 10-12 hours of straight run time

you're not seeing the switch that would turn it off because its not there

Okay someone help here as soon as i connect the wires to the battery it automatically turns on there is nothing to turn it off unless i get an on off switch

Yep.....if you have bait in your tank why turn it off?

There is a switch in between my pump and battery. Fish finders mostly have an on/off button so you don't need to run a switch

Running 2 batteries is the preferred method. No need to make it more complicated. Get a waterproof case for battery on or near bait tank, put battery in box, catch bait, hook up battery, run battery all day, unhook battery on the way in.

thank you easy day will attach it to bait bucket maybe will meet out there after im done fixing it up

I have my PA17 wired up for 12V on all systems. I got a smaller sized 12V motorcycle battery at Walmart for $50 and it runs everything all day. It is small and it fits in the front hatch easily and doesn't weigh that much.

I custom made a 26 gallon bait tank (Holds a full 1/2 scoop of bait) that sits in the middle of the kayak, an Elite 7 Chirp and running lights for those late evening trips.

Small
 

In retrospect . :D
