Just bought myself my first Fish Finder for my Ascend FS128T Kayak. Picked up a Garmin Striker Plus 9sv for a good deal.

 

I'm looking at opinions on batteries to use to run it. I have plans to add lights and a 30-40lb trolling motor in the spring.

On a yak I think you'd be sensitive to weight? I have a 10' Lowe Jon boat and use three Harbor freight 35Ah AGM deep cycle (see link) batteries and can be had for $56 with the 20% off coupon. Mine are 3 years old and are still in top shape. I keep them on maintenance with a noco gen3 charger. They are only 24 lbs and IMO are well worh the buckazoids.

 

I use one for a "house" battery, the other two for day long use. Before I got the second and third battery, the single one ran my Lowe with a second fisherman, all of our gear, a 50 lb TM and Garmin Striker 4 FF for 4+ hours (trolling not running the TM at 100%) before it dipped to the 11.7 volt 30% state of charge where I planned on being back at the dock. I imagine it would do a LOT better in your situation with a lighter more streamlined vessel and less gear.

 

Go LED lights they have a negligible effect on the charge.
