My older Minn Kota charger is done. Looking at the 4 bank MK precision 15 amp, Dual Pro Pro 15 amp and Sportsman 10 amp. I had the Sportsman on an older boat an loved it. The only thing I see might be a problem is the power cord is so sort on the Dual Pros and wont reach my plug port. I also like that the MK is a little smaller in height as room is at a premium. Will definitely be tight with the Dual Pro Pro. Other than that any major difference between brands. Any info would help. Thanks.
