I had a Dual Pro 3 bank 10 amp per bank that lasted 14 years. In fact it still works fine but one bank doesn’t quite switch to the final/maintenance mode once that battery is charged. I spoke with Dual Pro, the unit was an older model that was not repairable.
So, I pulled the charger and gave it to the guy that purchased my Minn Kota trolling motor of the same vintage.
I have purchased a Minn Kota 3 bank digital 10 amp per bank. Too early to tell how it performs.
Long story short I was EXTREMELY satisfied with the Dual Pro.
Minn Kota digital remains to be seen.
There is a rebate offer available on the Minn Kota.
