[#0000FF]There are a lot of variables in how long a battery will last. MinnKota says that the 30# motor will suck up 30 amps per hour at top speed. That means that if you have a 100 amp/hour battery it should hold up for about 3 hours at high speed. But that is seldom the case...especially if you are running it on a float tube and not a small boat or pontoon. You have a lot more drag in a tube than in a craft with a surface drag only. And every system is going to be different.
Also, your motor will actually suck up almost the same amount of juice on lower settings than on high speed...unless you have a maximizer motor that uses only the exact amount of power you need. Otherwise, even though you are going slow the excess power is used up as heat.
In short, get the largest battery you can afford and that will fit on your craft. Take good care of it and make sure it is fully charged before and after each trip. Get a voltage tester and check the voltage before and after a trip to see how much you used on that trip. After while you will get a feel for how much power your system uses and how far you can go before you have to get out and walk.
