Got a 12 v terrova that I am running 2 batteries parallel. I just got a minn Kota 220 charger that I am installing. I have a battery switch that has 1,2 and both options. What is the best way to set this up so I can charge both batteries and not hurt my terrova which is hard wired up front. I would like to use just one charger lead for this the other one goes to the cranking battery.
thanks
