    I can't remember who recommended Battery spec but they were great. Got my batteries today but upon looking at the terminals on the wheelchair batteries and the alligator clips on the trolling motor I see they don't jibe. How did YOU do it??

    What type of terminals are on the batteries? If they are for bolts you could do it this way.

    Find the right bolt size. get 2" long bolts. cut the heads off and file clean. After running the bolts in hand tight, put on a lock washer and then a nut. Tighten no more than 1/2 turn past hand tight. Next, two flat washers, one lock washer and a wing nut.

    Go to a auto parts store to get replacement crimp fittings for the alligator clips. You will want to place the crimp between the two flat washers. that way you get good contact. The lock washer under the wing nut will keep things tight during use.

    Good to go.

    Aaron, you probably got batterys that have 'spade' terminals...either F1 or F2. Cut the clips off the motor[ leave 5-6 inches ] so you can use them again. I put the opposite spade connections on them. Anyway. go to Shucks or whoever and buy the appropriate sized terminals that fit your battery and install them. You need to buy 'yellow'[size 10] connectors, that's the size of the wires on your motor.

    "Batteries" always reminds me of one of Don Cherry's infamous quotes during Hockey Night a few years ago, when asked what he thought about the interrogations at Abu Ghraib: "Red is positive, black is negative, and make sure their balls are wet"... Shocking; simply shocking!!

    I always forget whether I'm wiring in series, or parallel, but if you're wiring for 12v, Run your red wires together & your black wires together from battery to battery then to your motor's respective terminals.
    If you're wiring it for 24v then black (neg), to positive (red) from Battery#1 to battery #2, on one side, then do the opposite to the other side, & run your two wires, one red & one black, to their respective terminals on the motor.

    If you're still not sure you did it right then get an inexpensive voltage tester @ one the the local DIY centers, or an auto parts store. & check your voltage to make sure it will be applicable to your unique situation.

    And if I now have you thoroughly confused, (LOL), ......go online & Google it, to see a diagram & you can check it out to see if you have it wired right!
    Wouldn't hurt to put an inline circuit breaker in your system either.

    MitM,

    Forgive my ignorance but "Dammit Jim, I'm a FISHERMAN not an electrician". What is the difference between those configurations and why would I choose one over the other??

    Series, increase voltage=2x12=24. Parallel, increase amp hour(run time)2x12=12.

    Isn't my little Minn Kota designed for 12V?? Would the higher voltage make me GO faster?? Isn't run time your primary concern??

    Oh you'd go faster all right. for maybe a few seconds before the motor fried. 12volts means 12volts. Putting 24volts to it is like doubling the pressure in your plumbing. Something is going to blow.

    Think of voltage as the amount of pressure. Amp hours as the size of your storage tank.

    You can get a 24 volt motor. Lots more power. Lots more money.

    Got it. So moral is...12volts only...use one battery till she dead then switch to the other

    for a 12 volt motor, hook the positive of one battery to the positive of the other battery, then to the postivie wire on the motor, then do the same with the negative side. That way your battery lasts longer, but is still the correct voltage. Think of it like jump starting your car, you get an extra battery without getting 24 volts to damage your trolling motor.

    It's really simple. Here's an easy way to remember (at least it's how I learned).
    Think about how you put batteries in a two cell flashlight. That's a series connection.
    Each battery is 1.5 volts. The flashlight is a 3 volt light. +Battery1-+Battery2- =3volts.
    Series would be Putting the + to +, and - to -, 1.5v plus 1.5v = 1.5v. Like Jeff Bandy said same voltage but higher amperage.
