I dont have that brand but have the Ionic batteries at 50ah for my Ultrex. I can go on 3 regular fishing trips (+/-7hrs. per trip) before i decided to charge. After that 3rd trip, its around 60%. Now depending on how you fish, depends on what ah battery you would need. I dont fish rivers with current, dont fish with a heavy foot, or fish out in middle of wind on an open lake. My style of fishing allows me to use the 50ah. I do fish club tournements so at the end of a tournement day, i'll have used about 30% of the battery. If you fish harder than i do, you might look at a battery that has more than 50ah's....maybe the 80ah or 100ah range......i talk about percentage use, the ones i run have built in Bluetooth that uses an app so you can tell how much battery you have.
