What size wire is needed for a 24v 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.

What wire should I use for 24V?

For the Neutral, Live and earth ground, wire gauge for that level of current is 14 for relatively short cable lengths. Increase the gauge for longer lengths past 25 feet. For the DC 24V output terminals to the drivers, 20 gauge is fine.

How far can 18 gauge wire carry 24 volts?

Using the chart, if you are using a device that requires up to 417mA of power, you can run 18 gauge wire up to 451 feet.

What size battery do I need for a 55 lb thrust trolling motor?

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.

How many amps does a 50 lb thrust trolling motor use?

Thrust Trolling Motor has a max amp draw of 52 amps/hr but only 5 lbs more thrust. 3. Because of the larger windings in the 50 lb thrust model, lower speeds use less amperage for the same thrust.

How many amps does a trolling motor use?

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

What is the best battery to use 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.

Will a 24V trolling motor run on 12V?

24v hooked to 12v will spin for a while on a full battery but there will be no torque. You could stop it with your hand. It is like running your motor with half the spark plugs missing.

Why does my trolling motor have 3 wires?

The three wires are for a trolling motor that will operate on either 12 volts or 24 volts. 12/24 volt motors have a switch to choose which you want. Thus the third wire to send power to the 24 volt side of the switch. The red and black wires operate the 12 volt side.

Can you run 2 batteries on a 12V trolling motor?

Yes, it will charge both batteries. You may want to considering buying 2 new batteries to do this with. If you put two different batteries or one old & one new, it will pull off one faster than the other. I have 2 12 volt batteries hooked up in parrallel (pos to pos and neg to neg).
