How many amps does a 24 volt trolling motor draw?

Thread: How many amps does a 24 volt trolling motor draw

Max is probably going to be around 50A, but it varies quite a bit with speed setting, wind, current, boat weight etc.. Older service manuals are showing the Maxxum 74 at 45A max draw.

To use an example, a 55 lb thrust motor unit has a peak power draw of 40 amps. If you use the trolling motor for 6 hours at average 50% load of 20 amps, the trolling motor will then require a battery load of 120 Ah. (6 hours X 20 amps=120 amp hours).

Secondly, how long will a 24v trolling motor last? A typical group 27 battery will supply 25 amps of current for one hour. A typical grou 30 battery will supply 25 amps of current for about 2 hours. If you run your 24 volt trolling motot at maximum speed, you will be drawing about 25-30 amps from the batteries.

Consequently, how many amps does a Minn Kota 30 draw?

While the Minn Kota Endura C2 30 Freshwater Transom Mounted Trolling Motor (30" Shaft) model takes 32 amps/hr to get that 30 lbs of thrust, this one can do 30 lbs of thrust for roughly 18 amps/hr. 40 to 45 lbs thrust is roughly 29 amps/hr instead of the 42 amps/hr that those respective motors draw for the same thrust.

Will 24v trolling motor run on 12v?

For a cable steer or hand controlled model this will not hurt the motor, but it will considerably affect the performance of the motor. However, an electric steer motor, such as, the PowerDrive, Terrova, or Ulterra cannot be used on lower voltages.

How long will a battery power a trolling motor?

A battery with a 1 Ah capacity should be able to deliver a current of 1 amp or discharge for an uninterrupted 1 hour. As a general rule, smaller batteries are usually rated at 25 Ah to 50 Ah and bigger deep-cycle batteries could be rated as high as 100 Ah. There is no ideal amp-hour rating for a trolling motor battery.

Can you use a car battery for a trolling motor?

A car battery is 12-volts and can power your trolling motor. However, the length of time you'll be able to do so will be a fraction of the time a designated deep cycle battery could do it, and the car battery will have a dramatically shorted lifespan if you choose to deep-cycle it for trolling applications.

How long will a trolling motor run on a 12v battery?

(Just to keep the boat moving for slow drifts - musky or bass fishing). 6-8 hours seems reasonable with an older motor. Battery group size could play a role in life but on a 12v older power drive a 24 to 27 group battery running between 6-8 hours is in line with where you can expect yourself to be.

What size wire do I need for a 24 volt trolling motor?

In most cases, the manufactures recommended wire is 8 gauge for most 24-volt systems and 6 gauge for a system of 20 feet or longer. To account for voltage-drop, heat and current changes resulting from low batteries I recommend 6 gauge wire and 4 gauge for over 15 feet.

How fast will a 30 lb thrust trolling motor go?

In fact two 55 pound thrust motors will not move you any faster than one 30 pound thrust motor. Higher thrust 12V trolling motors are designed for bigger heavier boats with larger payloads. The maximum speed of a trolling motor is 5 mph regardless of how many pounds of thrust.

How often should I charge my trolling motor battery?

Charge them after every trip. If it sits for longer than a week, charge them again. Your batteries should be charging everytime you run the boat. if you run every week, you probably won't ever need to run the charger as they should be fully charged when you return to port.

Can you run a trolling motor out of water?

Your motor is cooled by the water around it, while running it out of the water for a very short time would be OK, it would take a long time to drain the battery much running the motor out of the water with no load. Why risk damaging a very expensive TM to just drain the battery down.

Do I need a circuit breaker on my trolling motor?

A trolling motor circuit breaker is designed to "trip" at a certain amperage, which breaks the circuit and prevents the motor from overloading and damaging itself. The exception are the MotorGuide Xi5 80 series, which require 60 amp circuit breakers.

How many batteries do I need for a trolling motor?

Most trolling motor batteries fail due to lack of proper charging. We suggest selecting a 12 volt deep cycle marine battery with at least a 110 amp hour rating, usually a group 27 size battery. The higher the amp hour rating, the more run time you will receive.

How long will a 35ah battery last?

Long answer: If the power output was not at 12v, then we would reverse the power equation to do 12*40 = 480WH. This means the battery can provide 480 Watts for 1 hour. 40AH (Amp Hours)/4.16Amps = 9.6 hours, or 9 hours and 36 minutes. or 480WH (Watt Hours)/50 (Watts) = 9.6 hours, or 9 hours and 36 minutes.
