This is only trolling so yes you would use a standard or agm battery for cranking and also charge that one at home as needed.
If you are running Sears Platinum DieHard 31M Series batteries (3 x 75 lbs = 225 lbs + on board charger (about 15 lbs) = 240 lbs total) - 90 lbs (Lithionics 36 V set up) = around 150 lbs of weight savings...
