CONNECTING THE BATTERIES IN SERIES
Automatic jump start systems and selector switches tie the negatives of the connected batteries together. Connecting these systems
to the “High Side” Battery or “Middle” Battery in the diagrams below and will cause significant damage to your trolling motor and
electronics. The only trolling motor battery that is safe to connect to one of these systems is the “Low Side” Battery.
The negative (-) connection must be connected to the negative terminal of the same battery that the trolling motor negative lead
connects to. In the diagrams below this battery is labeled “Low Side” Battery. Connecting to any other trolling motor battery will input
positive voltage into the “ground” of that accessory, which can cause excess corrosion. Any damage caused by incorrect connections
between battery systems will not be covered under warranty.

CONNECTING THE BATTERIES IN SERIES
(IF REQUIRED FOR YOUR MOTOR)
24-Volt Systems
Two 12-volt batteries are required. The batteries must be wired in
series, only as directed in the wiring diagram, to provide 24 volts.
1. Make sure that the motor is switched o (speed selector on “0”).
2. Connect a connector cable to the positive ( + ) terminal of
battery 1 and to the negative ( – ) terminal of battery 2.
3. Connect positive ( + ) red motor lead to positive ( + ) terminal
on battery 2.
4. Connect negative ( – ) black motor lead to negative ( – ) terminal
of battery 1.

WARNING
For safety reasons do not switch the motor on until the propeller is in the water. If installing a leadwire plug, observe proper polarity and
follow instructions in your boat owner’s manual.
WARNING
• For safety reasons, disconnect the motor from the battery or batteries when the motor is not in use or while the battery/batteries
are being charged.
• Improper wiring of 24/36 volt systems could cause battery explosion.
• Keep leadwire wing nut connections tight and solid to battery terminals.
• Locate battery in a ventilated compartment.
Additional Accessories Connected to Trolling Motor Batteries
Significant damage to your Minn Kota motor, your boat electronics, and your boat can occur if incorrect connections are made between
your trolling motor batteries and other battery systems. Minn Kota recommends using an exclusive battery system for your trolling motor.
Where possible, accessories should be connected to a separate battery system. Radios and sonar units should not be connected to any
trolling motor battery systems as interference from the trolling motor is unavoidable. If connecting any additional accessories to any
trolling motor battery system, or making connections between the trolling motor batteries and other battery systems on the boat, be sure
to carefully observe the information below.
