Electric motors and battery combinations...>>>
I'm looking for information about electric motors and the most efficient
battery combinations in terms of weight of adding a battery vs. the power that going to 24volt might give me. I live in an area that doesn't allow gas motors on its reservoirs; only electric motors, so I could only power my 12' jon boat with electric. I'd like to match up the most efficient combination of motor size, battery, and weight. I would like to know if I get longer run time and/or more power with a 50lb 12volt motor or a similar sized 24volt motor? Or, would I get a better weight-power-endurance combination getting a 36volt, 100+ lb motor?? Also, would I get more run time from 2 batteries (1 to run, and one as a spare, i.e., "refuel") with a 12volt motor, or 2 batteries running simultaneously on a 24volt motor? questions, questions, questions... -- Marty S.

I might be wrong, and this is strictly my experience speaking but I used to run a 12 volt system long ago in a galaxy far, far away. I had a 42 pound thrust motor and I would drain the battery dead long before I was ready to come in for the day. Then I went to two, 12 volt batteries on the same motor and found that I could go all day without problems. Then, I sold that boat and got one with a 24 volt system and a 60 pound thrust motor. I couldn't believe how long I could go on a single charge! It was far longer than running the 12 volt system with two batteries. I think that 36 volt would be overkill, but I think that if you were to get a 24 volt, 65 pound thrust system, you would be VERY pleased with the results. I believe that if you are running a larger than needed motor, you can run it on lower settings, thus saving on batteries. You'll have to run a lesser thrust motor on higher settings to get the same performance, and use up the batteries faster in the process. -- Steve OutdoorFrontiers http://www.outdoorfrontiers.com G & S Guide Service and Custom Rods http://www.herefishyfishy.com |

Perhaps I'm missing something... but wouldn't a 36 volt system require 3
deep cycle battteries... in a 12' boat? That's about 150lbs just in batteries. I run a 36lbs motor on 1 deep cycle battery. I can run it all day long... probably 2 days without recharging. But deep cycle batteries are ment to be recharged after each use. So I question why you would want more then a few days use from your battery/motor combination. "Marty S." wrote in message ...

On the other hand, I have a 50 pound thrust Minnkota on my little 14-1/2
foot glass boat. I'm hard on the battery, but I can easily fish two long days without a charge. I do run a group 29 deep cycle battery. RichZ© www.richz.com/fishing |

The reason is less voltage drop in the cables (assuming equal size). When it comes to batteries, there is no substitute for weight. More lead equals more power. Regarding the question of running from two batteries at the same time, or from one then the other, I'd vote for both batteries at once. You should get longer battery life that way since you'd be less likely to discharge below the 50% level. The advantage of course to first one battery, then the other, is the ability to get home after you draw down the first. Drawing down the batteries to zero is a recipe for short life however. |

But deep cycle batteries are
ment to be recharged after each use. Not True! IMHO they are designed to run down to dead and then be recharged without damage. Larry Hill |

You can use two group 27 batteries wired in parallel. It will pull the boat
around all day long. By putting them in parallel, it doubles the run time. The AC Delcos are 160 minute reserve capacity batteries. By putting them in parallel, it gives me 320 minutes of 25amp capacity. You need to get deep cell batteries with the highest amp available. Check amp draw on different model motors and get one with a low amp draw at full power. What is Amp Draw? .. Amp draw is the measurement of electrical current drawn from a storage battery (or battery), while the trolling motor is being operated at maximum speed. .. Minn Kota 's published amp draw figures represent actual on the water conditions (with all of the motor 's wiring, switches and circuitry in the electrical system as the test measurement is taken). .. Approximate length of running time when operation a trolling motor at full power can be determined with a motor 's amp draw and the battery amp hour rating. Example: A single 120 amp hour, 12 volt battery and a 12 volt trolling motor drawing 20 amps at the highest speed setting will run for about 3.4 hours. .. The formula for the calculation is as follows: ..85 A.H.R. = Hours of running time. (A.H.R.= Battery Amp Hour Rating) M.A.D. (M.A.D. = Motor Amp Draw) .. As the speed setting is reduced the motor amp draw is also reduced. .. A motor drawing 30 amps at high speed may only draw 5 amps at the slowest speed. The same motor that will theoretically run about 3.4 hours at high speed will run for over 20 hours at the slowest speed. Sarge |

I'm looking for information about electric motors and the most efficient battery combinations in terms of weight of adding a battery vs. the power that going to 24volt might give me. I don't know anything about electric boats, but I know a thing or two about electricity. The amount of useful work, ie boat moving, that you can get out of a motor and battery combination is a function of voltage and current. If you use more voltage, you need less current to do the same work. Conversely you need more current to do the same work with lower voltage. A battery has a limited amount of current in it that you can pump out into your motor to do work. If you put multiple batteries in parallel, the voltage remains the same but you have a greater quantity of current available to you. If you put multiple batteries in series, you increase the voltage, but the current capacity is the same as a single battery. Theoretically, it's a wash, assuming that you're using adequate wiring so that you're not losing a lot of power heating the wires. I suspect that the real differences we see in run time depend primariliy on the efficiency of the propulsion unit, that is how much of the energy that the battery squirts into the motor gets converted to moving the boat and how much of it gets thrown overboard as waste. I'm guessing that, all else being equal, typical 24 volt boat motors probably have an efficiency edge over 12 volt ones because their internal components are moving less current around and it's easier and less expensive to manufacture an efficient low current device than an efficient high current one. If you're using something to control the speed of the motor, the speed controller's efficiency would also come into play and the same rules apply. |

Larry:
This it true of some battery chemistries, but not lead-acid batteries. If you treat them that way, you will get a rather short service life from them. AGM batteries are somewhat more tolerant of deep discharge, but sulfation is still an issue. For best life with lead-acid batteries of any type, discharge them to no mor than about 50%, and charge immediately after use. Go to any of the battery manufacturer's sites, and the information you find there will bear this out. |

Or, would I get a better weight-power-endurance combination getting a 36volt, 100+ lb motor?? The full answer is not so simple. A partial answer that makes a bunch of assumptions that will be correct in most cases would be that the higher voltage system will be a lot more efficient. If you look just at the motor, the ability to turn electrical power into torque is a function of the number of amps flowing through the wire and the number of turns that the wire makes around the motor pole. If you have the luxury of allowing a large physical size on the motor then you can trade off number of turns for amps and use just about any voltage you want. When you want the motor to be compact, it is usually easier to have a low voltage, low turns, high amperage design. If the motor was the only consideration in the equation that would be the end of the disscussion. Unfortunately, you also need to consider the wiring to the motor, the controls and the batteries that feed the motor. All of these items favor lower current, higher voltage designs. While the physics of the motor can trade off voltage for current, the losses incurred in the wiring and controls will be effected only by the current, and will have no "trade off". If you double the current, then you need to double the wire size or you will lose twice as much energy into heating the wire. The biggest single impact on efficiency will be the rate at which current is drawn from the battery. Deep cycle batteries are typically rated at a "20 hour" rate or lower. At a higher draw, the battery will supply less. A typical battery, say a "Trojan" 27 series, is rater at 105 amp-hours at the 20 hour rate (5.25 amps for 20 hours). If you increase the current demand up to the 5 hour rate you will only get 79 amp-hours (this information is from the Trojan Battery web site). In general, the higher the current, the less efficient the battery will be. For maximum run time you will want the lowest current draw, hence the higher voltage system. Also, would I get more run time from 2 batteries (1 to run, and one as a spare, i.e., "refuel") with a 12volt motor, or 2 batteries running simultaneously on a 24volt motor? Again, maximum run time will occur when the current that the battery sees is at a minimum. You will get a lot more run time if you run two batteries in parallel than if you ran one until it was dead and then switched to the other. Rod McInnis |

that I don't need, which I'm going to be selling when Spring gets closer. -- Marty S. Baltimore, MD USA "Chris S" wrote in message ... Might want to also check E-bay as Ive sold my Minn Kota there and also have seen some good deals there as well Chris S "Marty S." wrote in message ... I'd like to thank everyone who responded for their advice on the topic of electric motors and battery life. (I can only use electric motors on the reservoirs near me). I will probably be buying a 65lb thrust 24volt motor this spring to go with my 12' jon boat. Given what y'all said and that I'd probably have two batteries in the boat with me anyway (either in series for a 12volt system or in parallel for a 24volt system (I think that's right??)), I think that this combination should be a reasonable balance of power, motor efficiency, and battery life. Now I have to wait for my Bass Pro and Cabela's catalogs to arrive!!! Thanks again. -- Marty S. Baltimore, MD USA "Capt. Frank Hopkins" wrote in message link.net... Perhaps you could use a "Honda" EX1000 generator to recharge the batteries on the fly. The unit is lightweight, whisper quiet and puts out 7 amps ac and 8 amps dc. Add in a decent battery charger and it would be like having an alternator. I keep larger (EX2000) unit on my boat (26' Formula PC) just to maintain the house batteries when anchored. The gene sips fuel with an eyedropper, and I can carry on a normal conversation with the wife standing next to it. Just a thought, CF Marty S. wrote: I'm looking for information about electric motors and the most efficient battery combinations in terms of weight of adding a battery vs. the power that going to 24volt might give me. I live in an area that doesn't allow gas motors on its reservoirs; only electric motors, so I could only power my 12' jon boat with electric. I'd like to match up the most efficient combination of motor size, battery, and weight. I would like to know if I get longer run time and/or more power with a 50lb 12volt motor or a similar sized 24volt motor? Or, would I get a better weight-power-endurance combination getting a 36volt, 100+ lb motor?? Also, would I get more run time from 2 batteries (1 to run, and one as a spare, i.e., "refuel") with a 12volt motor, or 2 batteries running simultaneously on a 24volt motor? questions, questions, questions... -- Marty S.
