How many amps does a trolling motor 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).

In respect to this, how many amps does a Minn Kota trolling motor 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.

Likewise, how much power does a trolling motor use? But small trolling motors usually draw about 20 amps per hour (at 12 volts).

Consequently, how many amps does a 70 pound thrust trolling motor draw?

Conductor Gauge and Circuit Breaker Sizing Table

Motor Thrust / Model	Max Amp Draw	Circuit Breaker
70 lb.	42	50 Amp @ 24 VDC
80 lb.	56	60 Amp @ 24 VDC
101 lb.	46	50 Amp @ 36 VDC

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

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). A battery bank of a 240 Ah capacity rating selected as deep cycling should be kept to 50% to ensure maximum battery life.

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 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.

How long will a 35ah battery run a trolling motor?

Lets assume my deep cycle battery has an RC rating of 140. Divide that by 2.4 and I get about 58 amp hours. Lets assume my motor is the Endura 30 mentioned above, and I troll at speed 2, which is 10 amps draw.

How Long Will My Motor Run.

Amp Hours	Amp Draw	Hours Use
100	30	2.8
100	40	2.1
100	50	1.7

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.

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.

How much can you discharge a deep cycle battery?

Automotive batteries will generally fail after 30-150 deep cycles if deep cycled, while they may last for thousands of cycles in normal starting use (2-5% discharge). Deep cycle batteries are designed to be discharged down as much as 80% time after time and have much thicker plates.

How many pounds of thrust do I need for a trolling motor?

Boat weight is the most important consideration to take into account when choosing a trolling motor. A beginning rule of thumb is that you want a minimum of 2 lbs of thrust for every 100lbs.

What size battery do I need for my Minn Kota trolling motor?

A Minn Kota trolling motor will operate with any lead acid, deep cycle marine 12-volt battery/batteries. For best results, use a deep cycle, marine battery with at least a 110-ampere hour rating.

How do I know if my trolling motor battery is bad?

Repeat ever couple of hours or when you notice a power drop. If one battery drops more than the others, that one is probably bad. If the batteries are being charged fully, start the day at the same voltage and discharge equally, then they are probably all worn out.

Are lithium batteries good for trolling motors?

The Group 24 - 12V 75AH Lithium Battery is ideal for most trolling motors and is widely used by anglers who want enough power to last throughout an entire day of fishing. Type of Use : Mid - High Level - Average 6 - 10 hours of fishing.

What battery do I need for a trolling motor?

Battery Type

There are two specific types of deep-cycle 12-volt batteries recommended for use with trolling motors: Lead Acid Wet-Cell & AGM Batteries. Deep-cycle batteries are designed for discharging smaller amounts of current over a longer period of time and for more frequent recharging.

How long will a 24 volt 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.

What is the best battery for a Minn Kota 30 lb trolling motor?
