Dual Purpose. Get as big as will fit in your space. Group 29 at least. You have an Opti? Make sure it's rated at least 1000 MCA.
While others say good things about the Optima batteries, I'm not a big fan. Not a good value IMO. Cost too much initially, and I don't think they perform as good as less expensive wet-cell or gel-cell batteries. Thy may last a little longer, but certainly not long enough to justify 3 times the price.
I don't think the products that provide charging from the boat motor alternating are really a good application for muskie anglers, who run and gunn all day. Big motor is just not running long enough to make a difference.
I always keep a set of jumper cables in my boat, with a plug for the the rear trolling motor recetacle on one end. They don't have to be a big set either. I bought a small set, in a bag from Fleet Farm. Cut off one end, and attached the TM plug. Put back in the bag, and it's in the glove box. The one time I had an issue with my cranking battery going low was caused by a faulty charger. Simple matter to plug in the jumper cables, and start the motor, compared to swapping out a trolling motor battery on the lake.
