24-Volt Systems
Two compatible 12-volt batteries can be wired in series to provide a dedicated 24-volt trolling-motor bank.
- Series battery-bank configuration
- High-current breaker protection
- Proper conductor sizing
- Dedicated charging support
Trolling Motor Systems
Trolling Motors Powered By a Proper Electrical System.
GeauxPower Marine installs, rewires and upgrades 24-volt and 36-volt trolling-motor systems, including dedicated battery banks, breakers, conductors, plugs, onboard charging and battery monitoring. The trolling motor is treated as a complete power system—not simply a device mounted on the bow.
Trolling Motor Power Systems
The motor, batteries and charging system must work together.
Trolling motors operate at high current for extended periods. Reliable performance depends on battery capacity, system voltage, conductor size, connection quality, circuit protection and proper charging.
36-Volt Systems
Three compatible 12-volt batteries or a purpose-built 36-volt battery system can provide power for higher-thrust trolling motors.
- 36-volt battery-bank configuration
- Series wiring or dedicated lithium system
- Breaker and disconnect protection
- Battery monitoring and charging
Lithium Trolling-Motor Systems
Lithium battery systems can reduce weight and provide high usable capacity, but the charging and protection system must be compatible.
- Compatible lithium battery configuration
- BMS and charging-system considerations
- High-current circuit protection
- Battery-state monitoring
Complete Power Path
Build the electrical path for the current the motor actually uses.
A trolling motor can draw significant current, especially at high thrust. The batteries, cable size, breaker, plug and all connections must support that load without excessive voltage drop or heat.
View Battery & Charging Systems
Battery Bank
Battery configuration must match the trolling motor's required
system voltage.
Conductor Size
Cable size is selected according to current demand and total
circuit length.
Circuit Breaker
High-current protection is installed according to conductor
and equipment requirements.
Plug and Receptacle
Detachable connections must be rated for the motor's voltage
and current requirements.
Battery Connections
Series jumpers and primary connections must remain tight,
protected and corrosion resistant.
Voltage Drop
Excessive resistance reduces available motor voltage and can
create heat at conductors and connections.
Disconnect Capability
Proper disconnect arrangements allow the trolling-motor
circuit to be isolated for service.
Cable Routing
High-current cables are supported and protected from abrasion,
sharp edges and mechanical damage.
Charging Systems
A trolling-motor bank is only useful if it can be recharged correctly.
The proper charging method depends on battery chemistry, system voltage, number of batteries and how the boat is used between trips.
Multi-Bank Onboard Chargers
Separate charger outputs can maintain each battery in a multi-battery series bank while connected to shore power.
Lithium-Compatible Charging
Lithium battery systems require charging profiles compatible with the installed battery manufacturer and BMS.
Alternator-Assisted Charging
Where appropriate, a properly designed DC-to-DC system can use available engine charging power to support a trolling-motor bank.
Charge-System Diagnostics
Charging voltage, charger outputs, battery condition and connection resistance can be tested when batteries fail to recover.
Battery Monitoring
Know what the trolling-motor bank is actually doing.
A shunt-based monitor can measure current flow into and out of the battery bank. This provides useful information about load, charging performance and remaining capacity that a simple voltage display cannot provide by itself.
Current Draw
See how much current the trolling motor is drawing during operation.
State of Charge
Estimate remaining usable battery capacity during a day on the water.
Charging Current
Verify that charging equipment is actually supplying current back into the battery bank.
Electrical Diagnostics
Abnormal current or charging behavior can help identify battery, connection or equipment problems.
Installation Process
Match the motor, battery bank and charging system before installation.
Review the Motor
Confirm model, thrust, required voltage, recommended protection and installation requirements.
Inspect the Boat
Evaluate bow mounting, battery location, cable route, existing breakers, charging equipment and available space.
Install the Power System
Install the battery bank, high-current conductors, breaker, connections, plug and charging equipment.
Test Under Load
Verify system voltage, polarity, breaker operation, charging and trolling-motor performance after installation.
Request a trolling-motor system review.
Send the boat year, manufacturer and model, trolling-motor brand and model, required system voltage, current battery setup, charging equipment, and photos of the bow and battery compartment.
