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.
Also know, how many amps does a 70 pound thrust trolling motor draw? more
How long will a 12v battery run a trolling motor?
Use Variable Speed Motors: Using a variable speed motor (vs. a fixed speed motor) generally results in significantly longer run times. Variable motors are more expensive – generally about $100 more than a comparable fixed-speed model – but are more energy efficient, especially at slower speeds. They are also much more convenient as they allow you to dial in the speed to the exact setting you want vs. having to select from pre-set speeds. For more details, see these notes on fixed vs. variable speed motors. here
A common question people have when trying to select a motor is “How long will this motor run out on the water?” To answer this question, it's necessary to know two things: a battery's amperage hour rating and a motor's amperage draw. Keep in mind that trolling motor run-time is not an exact science but the following parameters will help you approximate your potential run time. more
It's important to note that water and weather conditions can significantly affect battery performance. A motor drawing 20 amps to move a boat at medium speed in calm conditions may need 30 amps to move the same boat in strong wind or waves. If you plan on using your motor frequently in windy or stormy conditions, you'll want to factor this into your calculations.
Most manufacturers will only list a motor's maximum amperage draw at top speed, so you may need to estimate other amperage draws at various speeds using the max speed amperage draw as a baseline. [links]
100 amp hour rated battery / 20 amp draw = 5 hour run time
Don't Fully Deplete Your Battery: It's never good for a battery to be run completely bone dry. Doing this on a regular basis will almost certainly reduce the lifespan of your battery. If possible, try to recharge your battery(s) before they are completely empty. Using a battery life indicator – a handheld unit or one built into the motor – will help you monitor battery life as well as reduce the chances of unexpectedly running our of power miles from shore.
However, this also depletes the battery rapidly. Cranking amps are used to measure the power of car batteries. They are ideal for applications that need short bursts of power. more
Let’s consider that you have a deep cycle battery bank with an amp hour rating of 150. As specified above, divide it by 2.4. This means that your battery has 62.5 amp-hours. [links]
Usually, these batteries are not used with trolling motors, particularly for extended periods. In most cases, they are measured in terms of CA or CC, whereas Amp Hours and RC are also used once in a while. here
In the case of trolling motors, it’s better to go ahead with a deep cycle battery due to the higher number of amp-hours or RC, thus ensuring that your motor will run longer. here
You also need to know about the motor amperage draw. It is a rating that tells you how much current or amps a motor draws at a particular speed. It’s tricky to find the exact amp draw rating of a motor, but you can get in touch with the manufacturer or send us a message to learn about it. here
The function of a battery is clear to anyone who is a boat hobbyist, but not everyone knows how it operates when it comes to different types. The motor battery is used to store and hold energy for use.
Re: Trolling Motor Current Draw ?? here
I think the solar idea is novel , but not going to be practical in any way. You could use a solar panel to slow the rate of discharge on a battery, but frankly just put a mid sized to large deep discharge battery in the canoe and be done with it. I highly recommend the optima spiral cell batteries. I have a 34m that I have used in my pontoon boat for a few years that just got moved to my truck after the truck battery died. I just ordered a 31m optima to replace the boat battery. It is a 90 amp hour battery. I use a minn kota endura 30 as a small back up motor on the pontoon boat.. and like to use it to just maintain steerage while going down river. It is rather cool to be silent at night and just enjoy the river quietly.
Gonna say you can do it on 40 amps, but fuse higher otherwise you may be blowing fuses on long full speed runs. 6 AWG is kinda light for 40 amps, but since wires aren't usually bundled together tightly allowing the wire to run cooler, and with a good thermoplastic 105F coating on the hookup you should be good to go. 4 would do better, but in a boat you have to do a little compromising due to weight. Also, if you aren't hammering down on it at full throttle for extended periods of time. constantly, you won't have a problem.
I have a Motorguide 68lb Brute 12/24 and it has 40 amp fuses in line with each battery on 6 AWG wire, 17' boat. So, speculating, if I run on half the voltage the thrust will only be half so looks like this motor would deliver 34 lbs of thrust at a comfortable current below 40 amps on the 12v switch position.
I'm really confused on the overall logic. Two "really small" batteries (such as??) will likely have less capacity than one standard deep cycle. Using virtually any 12V troller (pulsed or not) will drive that canoe just fine for a great distance. As with a gas engine, it takes so much fuel to make so much HP. With an electric motor it takes a given amount of current to produce a certain amount of thrust. Yes -- there are certain technologies (we mentioned them) that can help prolong battery life at slow speed. But at their maximum thrust, both pulsed and standard motors will draw about the same current. Your choice is to go new technology or build your own pulse unit for an old motor - but don't be surprised if the efficiency is still worse than the newer motor. here
