*This makes my old motor look like a toy **enjoyable.fishing** recommend it's well built. I haven't had it on the water yet, but I'm very sure it will perform just fine.*

This was an excellent physics lesson. You really know your stuff! Your video really helped me realize the advantage of 24 volt. Based on your video, I decided to go with a 24 volt Motorguide Xi5 80 lb instead of the 12 volt 55 lb. I was just trying to avoid adding another battery and so I could use my battery switch. I decided on all Ionic lithiums which are very expensive, but I think I will be glad I did. Since they are two twelve volts, I can still take them out of series and have a backup in the event of main battery failure. I have a 2018 whaler montauk 170 that weighs about 2500 lbs loaded. I think the 55 lb 12-volt would have been at its limit (on the power curve) all day, especially because of the significant currents, waves and wind in the ocean here in Boston. For my old 12 volt minn kota 55 riptide in my old 15 ft montauk, I had 6 gauge wire going to my bow plug, which was a pain to fish from the console to the bow. With the 24 volt setup on my new boat, I went with 8 gauge wire, which will be easier to fish through and work with and since it only travels about 7 feet, it should be just fine. Thank you for helping me avoid a mistake. Since I already made the decision to have a saltwater trolling motor - mostly for the spotlock feature to avoid anchoring in waters over 100 ft - I should make sure it can actually do the job and not become a toaster oven.....

Finally.....someone who understands Ohms Law! Thank you so much for your in depth explanation!

Thanks, Keith! Short answer is yes. Exactly how much depends on the AWG of your power wire, and the length to the battery, however, the most significant reason it will be more efficient is there will be a lot less % of power loss in the trolling motor itself at 24V. 5% minimum advantage, but could be as high as 20%

Short answer is "Yes". In all instances, a higher voltage is always better for power distribution. The only difference I can see is the wiring internal to the trolling motor itself is much more than most powered devices in an RV, except maybe the refrigerator. Trolling motors have way too much wiring inside, up to 100', so it's doubtful you have anything in your diesel pusher that has that amount of internal wiring. Obviously, each powered device must be able to handle the higher voltage. Hope this helps.

Hi Dennis. Yes, there should be no issue buying a new version of the same make and model of battery and putting them in parallel.

This will minimize inrush current between them. Hope this helps.

Hi Eric Just watched your talk on 24v vs 12v system and found it very informative. The reason I watched it was that I tried to convert my 2hp petrol to a 24v electric with a motor I acquired but unfortunately the motor was defective and couldn’t handle it. Anyway I am now looking for a trolling outboard for my dinghy but have a dilemma. I’m in aviation so acquired a couple of 24v sealed lead acid batteries @ 13.6 ah each but I also have a 12v lead acid @120ah. I know on the face of it the 12v has more amp hours but I also know that the 24v system would draw less amps. So eventually, here is my question, do I buy a Bison 100lbs 24v for £240 or do I buy a 65 lbs Bison for £199? I’m asking a man who knows about these things so I don’t waist my money and get it wrong. One more thing, the dinghy is used to get us from a swing mooring to the jetty 300 meters away and too and from the pub about 1/2 mile away. Any help would be greatly appreciated. Dave

I have a NOCO genius 12 volt lithium charger with 3 banks. If I place one set of leads on each of the two lithium batteries in series - I am thinking it will charge the two at above 24 volts, because they are in series and the charger's voltage will also be added together. I first ordered a separate 24 volt charger but then realized I didn't need it and canceled it. Was I right?

@GoldenChannels

Tim, Thanks for your comments. The most direct answer I can give you on whether a 12V charger can be used to charge 2 x 12 V wired in series, one at a time, would be to contact the battery charger manufacturer to ask them the question directly. The answer lies is how the charger is designed, internally. Some will work, and some won't. If you have any other shore power connections to your boat will also come into play here. The main factor is where ground is in both the charger and your shore power circuits.

I have a 12v trolling motor that I have two batteries for. I also have a starter battery. I use a 3 bank charger to charge my batteries. If I were to connect the two trolling motor batteries to make them 24v could I still use the 3 bank charger?

@GoldenChannels

Жыл бұрын

Thanks for your comments. Glad to help. It is very difficult to find good answers on line for this kind of question. This is due to a number of variables that come into the equation. Things like hull design, weight, and trolling motor thrust all come into what can be expected for speed. My boat weighs about 2,500 lbs. Our 150 HP outboard will push it along at a maximum speed of around 50 mph. When trolling, our 55 lb 12V powerdrive trolling motor gets us to a top speed of 2.1 mph. This suits our needs. I generally troll around 1.5 mph, and keeping everything on a 12V system makes charging easy. My only recommendation for you would be a slightly larger group 29 battery. They will give you quite a bit more run time with only slightly more weight. I would expect somewhere around 2.5 to 3 mph to speed from the setup you are describing. It should definitely be sufficient for trolling.

I am curious about the weight difference between 12v and 24v gps trolling motor. The reason for smaller boats to choose 12v motor is because we want to minimize weight for easier transportation. Any data on that would be great!

@GoldenChannels

2 ай бұрын

The batteries required far outweigh the weight of the trolling motor. I guess that is why you don't find much data on it. If you have a 12V trolling motor that does not have the large coiled cord running from top to bottom then you have significant savings in power loss due to wiring. If you only need the thrust of a 12V, and can use one that is constructed like this, it would be an excellent choice.

I see everybody has questions regarding their equipment and it definitely has me curious about mine! I have a 75lb single seat pontoon boat with a 62lb thrust newport vessel trolling motor running on a 12V battery and it seems to run strong however i’m thinking about upgrading and adding another 12V battery for full motor potential... Is that a bad idea for such a small boat haha?

@GoldenChannels

Ryan, probably the most significant aspect of adding another battery for you (assuming the added weight isn't an issue) would be that after a day on the water, your batteries would only be half the discharge state they are in now after a day. This would make them live longer, since the deeper you discharge them, the shorter their life.

A good question. The 24V Trolling Motor providing 55 lbs of thrust will be more efficient, and therefor will keep going longer from a similarly sized battery setup. If you want to do a direct comparison for the specific motors you are comparing, you can punch in the numbers on our trolling motor wire calculator here: www.goldenchannels.com/electric-trolling-motor-power-loss-calculator/ Current being supplied to both motors will be nearly identical, less the mechanical losses due to the 55 lb being full throttle. The 24V motor at 55 lbs of thrust will lost a quarter of the power through the wiring as compared to the 55lb, which is significant, especially with longer shaft models and those installations with 20 feet or more of wire from the batteries at the back to the trolling motor at the front. Tiller handled versions will be less affected by the voltage difference. Hope this helps.

Hi Robbie. Sounds like a great setup for a kayak. My first comment would be that the Trolling Motor Manufacturer should have a "rigging guide" that would contain their wiring suggestions for each model of trolling motor. This would specify the AWG size versus length. On our website, we have a power loss calculator for Minnkota and MotorGuide models, but not for your brand. Calculations may or may not hold true, depending on the wire using internally in your trolling motor. goldenchannels.com/electric-trolling-motor-power-loss-calculator/ The calculations and data provided on this calculator are based on the two manufacturers rigging guides. My second point would be to choose your connectors wisely. We got out of this business because it was so competitive, but still have some reviews here. If you connections get wet, use connectors that have some moisture protection. None are actually "waterproof". I do not currently think that any one manufacturer has a perfect solution. Lastly, check forums about discussion with Lithium with your particular motor, and see if anyone has run into issues with them delivering too much power to the motor when cranked wide open. There are some folks saying the lithiums are not recommended at over 80% speed, because they will deliver more power under load that traditional lead acid batteries. We can help you with well built wiring, but like I said, we're out of the connector game. Hope that helps. Eric.

Minnkota has a chart for this that is here: www.minnkotamotors.com/support/rigging Hope this helps. If you have further questions, I'm also hanging out at the group "Golden Channels" on Facebook, or you can post your question about specific motor size here.

When two 12V batteries are connected in series to a 24V motor that draws 40A at full throttle, does each 12V battery deliver 20A or 40A to the motor in this mode?

@Jean-Pierre Abello Good question. If you have one battery that cannot keep up, generally the voltage across both will drop, since they are in series. Since the trolling motor requires power (volts x amps) to maintain speed, it will pull more current, which drops the voltage lower again. This causes the healthy battery to work even harder. After an outing, if you turn your trolling motor off for a half hour or so, then measure each battery with a volt meter, the reading should be close to identical for both batteries. Hope this helps.

@Jean-Pierre Abello That will give you a good idea of how much current is being pulled by the motor. Exactly what problem are you trying to fix?

I have a 55lb Neraus Motor running through a 60amp PWM that works fine. I have also connected two relays to enable a reversing function but over a period of time discovered the plastic relay holders and wring were not up to the task and started to overheat and distort. As a result I have now fitted ceramic relay holders and thicker wiring from the PWM to the relays. Im considering upgrading to a 24volt trolling Motor again from Neraus on Aliexpress and would run it through the same PWM. My question is what impact on Electricity flow do you think a PWM has ie Voltage drop at full throttle.? and as my reversing relay wiring is probably 10 gauge is this too detrimental to the whole system ? If so I can forgo the reversing function and run straight from the PWM to the Motor or use Anderson Connectors to connect and reconnect.the reversing function as needed.

Hi Wayne. First question: Are you using proper marine wire? This is the stuff with lots of small strands, and each one is tinned/silver? I don't have direct experience with your tolling motor. I had a look at one of their models on AliExpress. It seems straight forward enough. From your note, I assume the PWM controller is separate, but can you send me a picture of exactly how you have this hooked up?

@@Wayne-xy6yw Some ideas to help: I think your relay connections are just .25" quick connects. If you have some of these, try one and if it fits securely, you could get a few that can take an 8 AWG wire. You might want to check if the relay's contacts have corroded by checking the resistance between the ON connections with the relay activated. If this connection has built up resistance through corrosion, the relay may fail. The relay appears to be sealed, but hard to tell. Usually electronics used in wet environments will have what is called conformal coating (looks like thin laquer) to protect the circuitry and traces. I can't tell if the PWM controller you are using has this, as well as the potentiometer is not sealed, so moisture will get inside of it eventually create problems. Sealed potentiometers look something lie this: www.digikey.ca/en/products/detail/bourns-inc/3590S-2-103L/1088586?Potentiometers%2C%20Variable%20Resistors&Shopping_Supplier_Bourns_0118_Co-op&productid=1088586&gclid=CjwKCAiA4o79BRBvEiwAjteoYLG758L6WsPn6mzW8xHOqpbndiIV5f7u_f_c1hKlME-BlZKmTd6mvBoCvdwQAvD_BwE Measuring PWM voltage is impossible with a voltmeter. You can tell what is going on with an oscilloscope, but most people overthink PWM. At the risk of telling you what you already know, PWM just quickly pulses the motor in an on/off/repeat quickly manner, and the speed the motor goes is pretty much set by how much the PWM says "on" versus "off". This is what is called Duty Cycle. When the PWM is in an "on" state, the motor is pulling the full current for that fraction of a second. If you are only on 10% of the time, or 90% of the time, the loss through the wiring is the same during that "on" period, but just not as noticeable since the motor isn't going as hard when at low speed. I see you have 8 feet of wire between the PWM and the motor. Did you also have about the same length from the battery to the PWM? Assuming even 5 or 6 feet, or 13 feet on both positive and negative, you voltage loss is 2/3V at 55A, or about 40W of power. When your motor is going full throttle, it should be using about 660W, so you're losing about 6% of your power through your wire. This is pretty reasonable. And that power loss will drop significantly if you go with a 24V motor. One last comment, and this is not meant to be a criticism, more of a bit of shared knowledge based on my electronics manufacturing background, to hopefully help with your future projects. This pertains to safety ratings. Some manufacturers (I'm not going to get political here) save money by not going through the testing procedures to meet well understood industry standards. An example would be power adapters, relays, etc. UL has a particular test method for ratings on relays. They are one of many industry bodies that put a rating and test method in place for many types of products. For example, this relay for a Raspberry Pi has a number of safety ratings from a number of international agencies: www.amazon.com/Tolako-Arduino-Indicator-Channel-Official/dp/B00VRUAHLE On my example rating, 3 independent testing labs have performed industry developed test to ensure this relay is safe and can handle the voltages and currents they tell you it can handle. In the old days, we used to buy stuff at a retail store, and when that retailer brought products into the country, a customs officer generally checked documentation showing correct certifications. Now, consumers are left a bit on their own. Each one of those safety markings costs the manufacturer a minimum of $10,000 and sometimes more, to submit the product for those safety tests. They're generally a mark of a better product. One thing I like about your setup, is you appear to have had good service out of the motor itself, correct?

I have a 12 volt MinnKota PowerDrive with iPilot that works great. I fish for two or three hours at a time at low power settings in a 16' aluminum skiff. Based on the 3 hours or less that it takes to recharge, my 85 Amp/hour battery is using less that 40% of it's capacity per fishing session. It goes back on the charger as soon as I get back to the dock. There is little reason for me to add another battery or two as well as a more expensive 24/36 volt charger. I'm sure that 24/36 volt motors have some significant advantages but they would be of little or no benefit to me.

I absolutely agree! 12V systems have less technical issues to overcome. Chargers and charging systems are simplified, due to the 12V design being more common, and if you want, you can charge with a standard isolator like you are doing.

Hi Robert. It depends on the charger. If you have your trolling motor battery banks and trolling motor completely separate from all the rest of your electronics, and not connected to your engine charging circuit, and you are only charging from shore power, there are chargers that will charge two 12V batteries wired in series as a single 24V bank. Most of the trolling motor specific chargers tend to make you think of always using 12V batteries as separate charging "banks". So, if you have two 12V batteries for a 24V motor, they want to sell you a "2 bank charger". Assuming both your batteries are the same brand, age, and capacity/model, there is no reason a 24V charger designed for the battery chemistry you are using cannot charge both wired in series together. For example, if you have two 12V Series 27 AGM batteries wired in series, you can charge them with an AGM 24 V charger. At the end of the day, a 24V battery is electrically identical to two 12V batteries wired in series. There are simply twice as many cells put in series to get to the correct voltage.

I'm dumb so excuse me..I have a 30 thrust on my Jon boat with 1 battery and my new bass boat came with a 40 thrust 24v ...does that mean my 40 will be 2x as strong as the 30?

@GoldenChannels

2 жыл бұрын

It's a good question, and trolling motor thrust ratings are confusing. And, since I don't know exactly how both boats are wired, I can only give you guidelines that the 40 will provide about 25% more thrust power to the water. Thrust also does not translate directly into speed. Considering that your bass boat is probably fiberglass, and the Jon boat lighter aluminum, I suspect that your bass boat will most likely not be much faster at top speed than the Jon boat. Also, your Jon boat's trolling motor is probably also a tiller handle. So, there is less overall wiring in it. If you want to actually calculate the difference in how much power is lost in the wiring of both setups, we have a Trolling Motor Wire Calculator on our website that might be helpful: www.goldenchannels.com/electric-trolling-motor-power-loss-calculator/ Sorry that I couldn't give you more of a direct answer. At the end of the day, the most we can do is give you guidance on the best installation practices. There are so many combinations of trolling motors, voltages, and boats, that is is hard to understand what kind of outcome you will get until you actually try a setup out on the water on the particular boat.

The armature and brushes, the main control board in the bottom of the motor, where it mounts to the boat, the little board that shows you how much battery you have left, and the sticker that says "70" instead of "55". With my boat, I can get just under 2 mph from my 55, and with another battery, and large cables, I'm right on the edge of just okay. The thing I don't like is what happens to your charging system when you have the 24v bank for house and the 12V for starting. Now there is more stuff you need to add if you want your engine charging the trolling motor battery. Have you given that thought?
