Put the lithiums in your new/next boatYes but the cost advantage needs time to play out. If you are gonna trade the boat in 3 years you are going to take a beating. Duel pro can program their chargers to specs for lithium. Minn Kota PC chargers set at AGM parameter are good for Lithium. The charger needs to be OK'd by your battery maker and you are good to go. It is a big chunk of money up front. I am sure it is over most young guy's budgets. I was there for many years. I think prices will steadily get more reasonable through competition. If you can afford them and are gonna keep your ride long enough it is a good investment. My replacement warranty is 3 years and the next 2 are prorated. I hope to get 8 to 10 out of mine. Lord willing I last that long. Bob
