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.

Also know, how long does a deep cycle battery last with 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.

In this manner, 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 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.

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.

Can you use a regular 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 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.

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 many amps does a 30lb 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.

How long does a 12 volt trolling motor last?

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.

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.

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 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. For example, if you have a 3000lb boat, fully loaded, then the calculation is (3000/100) * 2 = 60lbs of thrust.

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.

How much power does a trolling motor use?

But small trolling motors usually draw about 20 amps per hour (at 12 volts).

How deep should a trolling motor be?

The rule of thumb is that the top of the motor section should be submerged 12".

How long does it take to charge a trolling motor battery?

The amount of time a battery needs to be re-charged, generically speaking, is based upon it's amp hour rating. Example: a battery with a 640 amp hour rate charged at a rate of 2 amps (per hour) will take 320 hours to fully re charge.

Can you use a lithium battery for a trolling motor?

Minn Kota trolling motors can run on Lithium Ion batteries. However, they are specifically designed to run on traditional lead acid batteries (flooded, AGM or GEL). Lithium Ion batteries maintain higher voltages for longer periods of time than lead acid.
