A rough guess at trolling motor horse power is to apply the conversion of 1 hp equals 750 watts. A 12 volt motor using 20 amps is using 240 watts, or 240/750 = . 32 hp.

Likewise, people ask, how many amps does a 12v 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).

Beside above, how many amps does a 45 lb thrust trolling motor pull? 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.

Consequently, 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.

How fast will a 55 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 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

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 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

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.

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

In most cases, the manufactures recommended wire is 8 gauge for most 24volt 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.

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 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.

Do I need a deep cycle battery for a trolling motor?

Deep Cycle Batteries. Because trolling motors require a steady, consistent source of electrical power, you’ll need to use either a dual purpose or a deep cycle battery. These two battery types are designed to gradually discharge a large percentage of their total capacity over time.

Can you run a trolling motor off a solar panel?

Although it’s not an established fact, it seems that the currently available trolling motors draw more power than today’s solar panels are able to put out constantly. In order to use solar power on a trolling motor without a battery, you‘ll have to mount several high-end panels on your boat.

How long will a marine battery hold its charge?

Multi-stage Battery Charging

Over time, these deposits will cause a 200 amp-hour battery to act more like a 100 amp-hour battery, and battery life will be considerably shortened. Once fully charged, marine batteries should be held at a considerably lower voltage to maintain their charge – typically 13.2 to 13.4 volts.

How long will a deep cycle battery last calculator?

The key is to use the watts you know to calculate the amps at the battery voltage . For example, say you want to run a 250 watt 110VAC light bulb from an inverter for 5 hours. Amp-hours (at 12 volts) = watt-hours / 12 volts = 1470 / 12 = 122.5 amp-hours.

How long will an electric motor run on a battery?

The larger the rating, the more power the battery can hold, and the longer it will be able to power a motor at a given speed. For example, a 100 amperage hour battery is one that would be able to supply 25 amps of power for 4 hours (25 amps * 4 hours = 100 amp hours) before running out of energy.

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.

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 size trolling motor do I need for my boat?

Trolling Motor Thrust Guide
Boat Weight (lbs) 1,500 4,000
Boat Length 14-16′ 21′
Minimum Thrust 55 80
Performance Thrust* 55 112
Motor Voltage 12v 24v

How do I choose a thrust for a trolling motor?

Boat weight plays a vital role in selecting the correct trolling motor for you needs. A general rule for determining the correct amount of thrust is adding 5 pounds of thrust for every 200 pounds of weight.
