I'm just full of questions lately...trying to make some decisions. I have a Tracker PT 165 with a 24V 70lb. Minn Kota Maxxum trolling motor. I want to upgrade to the Terrova. With a boat this small, I don't think I need 70 - 80 lb. thrust but if I go with 55 lb. thrust it puts me down to a 12 volt unit. My batteries are now wired in series to give me 24 volts but only ~ 120 amp hours. If I go with the 12 volt unit, I would re-wire the batteries in parallel which would stay 12 volts but give me ~240 amp hours. Which is better? It would seem to me that more amp hours would be better for battery life and I would still have the power I need at 55 lbs. thrust.
