My current boat came with Interstate batteries. I used to have a Smokercraft (Lund-type boat) and installed an on-board charger. Had to replace the battery in the spring that year. I don't recall what kind of batteries I had, but they would have come with the boat. I troll a lot with my electric motor. but most of it is just positioning or keeping on top of the structure that I am fishing. My current boat is about 4 years old and I just replaced the trolling motor battery last year with something from wallyworld. I have a Suzuki 50 HP 4-stroke on my boat and I troll with it a lot-mostly crankbaits.
the trick to catch that finnicky speck....
gently set the hook just before the peck
