    I pack a 12volt battery into lakes that I fish on. These normal batteries are very heavy. I use one to propell an electric trolling motor. So the Mighty Max lithium 12 volt battery weighing only 14 pounds is much easier to carry into the lakes we pack into. The lead acid battery I have been using weighs 55 pounds. At 80 years old I really appreciate the Mighty Max lithium battery.
