You can connect both to the same battery, the FF doesn't come with a 12V plug in (lighter plug), just wires, but you can put one on if you want. here

I'm looking to buy a MinnKota 30 trolling motor for my inflatable boat, as well as a fish finder. What will it take to hook the finder up to the 12v trolling motor battery? Could the end wires of the finder be attached to the same battery post that the trolling motor is attached to?
Re: Connecting trolling motor and fish finder to same battery
The box works well to keep the battery protected and secure, plus allows connection options, so for a small boat it can be of value.

He described the batteries as two big tanks holding amps that you could think of as “gallons.” Volts are the pressure pushing the amp gallons through the wires like water through pipes. Doubling the pressure from 12 to 24 volts moves the amps twice as fast through the pipes, so two batteries are emptied by 24 volts in about the same time as one battery is emptied by 12 volts.
Simply put, wiring batteries in parallel increases their amp capacity while voltage stays the same, but wiring them in series increases voltage while amp capacity remains the same.
If you look at the top of a plain old flooded-cell, 12-volt marine battery, you see two widely separated metal posts and plastic caps lined up to cover six holes. The six holes let you replace water lost from each of the battery’s six cells during normal discharging and recharging. A 12-volt battery is really just a box containing six two-volt cells that are wired in series to produce 12 volts. The positive side of one cell is connected to the negative side of the next in a sort of daisy chain that adds the voltages of all the cells together.
Three batteries are daisy-chained together in series exactly the same way to get 36 volts to power a 36-volt motor. The trolling motor’s negative power cable attaches to the negative post of the first battery. A jumper wire connects the positive post of that same battery to the negative post of the second battery. Another jumper wire is then installed between the positive post of the second battery and the negative post of the third.
Let’s say we have a 12-volt trolling motor and we want it to run two or three times as long as it runs on one battery. We can increase the running time by adding one or two more batteries to the motor’s original battery and wiring them together in parallel. We simply connect all the positive battery posts together and then connect all the negative posts together. No positive-to-negative post connections are made. As far as the trolling motor is concerned, it sees only one big battery with two or three times as many amps. [links]
Wiring two identical batteries together in parallel doubles the total number of amps available, and an engineer once told me that many people mistakenly think that you also add the amps together when wiring two identical batteries together in series. That doesn’t happen.

If you are someone who loves boating or frequently goes out in the water, there is a high chance you will need to learn how to connect trolling motor to battery. Trolling motors are famous for their exceptional features as they are adjustable and help the boat with manoeuvrability. Most of the times, people don’t know how to connect the wire to the battery so that the motor can be used on the boat and this leads to a less fun experience on the waters.
If there is one 12V battery, only this process is required. If the motor is on 24 volts and there are two 12 volt batteries included, then you take the black lead from the motor and connect it with the negative terminal of the first battery. Then take the red lead from the motor and connect it to the positive terminal of the second battery. After this use a jumper wire to connect the positive terminal of the first battery to the negative terminal of the second battery. You are required to use a 40 ampere circuit breaker for this. here
For the right procedure to be followed, you require some specific tools. You need a trolling motor control that includes remote control and hand filler. You need to have batteries that have been chosen according to the need of your boat. You may use one or multiple batteries connected in either parallel or series. To fix the motor power leads with the battery, terminal ends are required. In case of higher voltage batteries being connected together, you need a jumper wire as well. A circuit breaker is supposed to be used for protection, along with a trolling motor boat that helps in a speedy disconnection with the motor boat. The trolling motor is easily removed by a quick release plate. You might require extension wirings because there might be more than one battery to be connect and the jumper wire might not be enough for it. You also need some power leads.
If the motor is of 36 volts, you require three 12V batteries. This process is a bit complicated but once you understand it, you can do it without any problem. Connect the black lead from the motor to the negative terminal of the first battery. Then connect the red lead from the motor to the positive terminal of the third battery. After this you require two jumpers. Connect one from the positive terminal of the first battery to the negative terminal of the second battery. Use another jumper to connect the positive terminal on the second battery to the negative terminal of the third battery. You will finally have a 36V motor. [links]
