The depth of your prop will change your power draw as well. 8" of water above the prop seems to work well in my canoe with a transome mount. If you go deeper you end up adding additional pressure to the prop which kills the battery.

Thank you for this. It will help me with my trolling motor both during normal use and when using it to get back home if the motor fails on my Jon Boat. Your graph makes sense though. My all-day cruising speed on my pedal drive kayak was about 3mph. I could get above 4mph… but my legs would be burning horribly after 30 seconds.

Fantastic video. I just finished my 5th fishing trip on my Sportsman 106 powered by minn kota. Love it.

The rabbit might be fast, but the turtle wins the race. Lol. Just troll on your way to the fishing spot.

Way awesome vid, one small thing, It's amp hours, not just amps, when talking about how much you have taken out of the battery and how much you have remaining (state of charge). Super informative data, clearly presented, no worries about the Ah versus A thing, I knew what you meant, the info and the testing and graphing were great!!!

Best illustration of this topic out of any other video on you tube !!

As voltage drops, amps used rises. This is due to the motor wanting to use the same amount of watts (voltage x amps). This would exacerbate the differences since SLA batteries have a much faster voltage drop. Just something else to keep in mind when calculating distances.

Thank you, I've been trolling youtube and the Internet for this useful information to see whether I can go fully electric. The graphs showing the relationship between speed and current drawn are very helpful. All other videos seem to prioritise top speed, OK for getting out of trouble, but not for day to day sustainable use. Thanks again for an intelligent report.

Thank you! I appreciate the level of detail you went in to.

Although I do not have a motorized kayak at this time I found the content to be very informative. Your evaluations were spot on for me considering going to motorized version.

Great Video! I'm considering buying a kayak and your info is very helpful. I had already kind of planned on a lithium and your info has convinced me that it is the way to go. Thanks

Nice job sharing this information! Appreciate the work. Now I have a better understanding of how my battery will perform in different conditions.

Hands down the best information on KZfaq. Thank you so much. So many questions answered

Thanks for the graph. This really rings home true to me with my pedal kayak. I can cruise at 3 mph for a long time, but getting up to 4 mph is so much more work, and I can’t sustain it for long.

For a comparison I checked the current draw on my bow mount Minn Kota on a 16ft Lund Rebel. 20A draw at 2.0 mph. I am using a 100AH Ionic battery. It also has Bluetooth but was almost twice the cost of the reBel.

More information than I know I needed, thank you for this!

Great information, thanks for the time and effort you put into the research on this. I’ll be getting my OT autopilot 120 in August, so it’s good to see what others with more kayak experience use and recommend.

Excellent video. Will help me when planning my trips fishing. Thanks.

Well, not surprising when you consider one kayak is 77lbs and the other is 119lbs. My canoe is 60lbs, so I guess 3mph will give me excellent range. Thank you for doing this comparison and computation. Looks like conservative use allows for reasonable range, current, and wind.

if you kept the speed 3mph or less..you could run around for weeks on a charge on lipo.

Great content! I will be looking into Rebel batteries when I am ready to upgrade. I like that they are a veteran owned company.

one factor I'd like to see integrated in is motor size and how that changes your numbers

Very informative and since i use that same reBel battery, very useful. I am jealous of the area you are fishing as well, that place looks awesome. I just got my mk 106 and have yet to take it out, but I will be doing so shortly.

Very informative on Battery usage excellent

This was an awesome video idea. I am in the process of adding a trolling motor to my Jackson BigRig and will definitely go with a Bluetooth enabled battery for monitoring. A Rebel battery, if they have them in stock. As of today 8/12/22 they are Out. ☹️

Thank you, great information!

very detailed thanks!!

Bravo on the vid man ! ..... Hats off ! ..... Can u add one more thing to this test plz ? Been vids on the tube showing people using a rc plane prop on the autopilot 120 ( they def show a lil more speed ) and I think I might remember one guy saying it's more efficient / draws less . Can u please put this to the test and show us the numbers for the plane prop on the autopilot 120 ? Thanks

Paddling sucks on the AP 136. Can I call someone for water tow service if I get stuck? 😆

I’d like to see a video of how well the Autopilot can be paddled with and without the drive unit in it. If you kill the battery, can you get back to shore without wearing yourself out?

Good job 👍🏻 👍🏻 👍🏻 🤩🤩🤩

Actually it's worse for lead acid than your graph shows. 12.3 volts is at half capacity for lead acid. Below 12.3 volts, your lead acid battery is experiencing damage and reducing it's life cycle dramatically. This is where lithium really shines. Furthermore, the Pukert effect is also in play as internal resistance also cripples lead acid vs Lithium. To match the performance of a 100ah Lithium battery you actually need 300ah of lead acid TO COMPETE. But lead acid again loses as they STILL fall way short of usable lifetime as they can only be recharged around 300 times vs up to 5000 times for Lithium, and after that lithium STILL retains 80% of it's usable capacity. The cost of ownership of lead acid technology is FAR higher than Lithium when lifespan is considered. I have 200ah of Lithium in my BKC TK122U fishing tandem loaded down with a 55ft/lb trolling motor trolling for Kokanee on Bitterroot Lake. All day no problem and usually use less than 100ah. I make plenty of full throttle bathroom trips to the dock and back out to the fish. No way would I ever consider lead acid which would weigh 480 pounds (6, 100ah batteries) vs 50 pounds for just my one, 200ah Lithium.

i was out trolling yesterday in my ot 106 and 100 a/h li bluetooth for 5 continuous hrs in a light wind and used 21%.

Great subject for a video, but I think that you should really be saying Amp-hours and not amps since you are integrating the amps drawn over a time leading to a unit of amps*time. A battery has a capacity defined by its charge (Coulombs). Amps*time = Coulombs/time*time = Coulombs which is what you are really describing.

The best thing that has helped my range is losing a bunch of weight

Buy a litium battery you can use 100% of the battery leaded battery arnt designed to go lower 50% as this damages them bought a lithium battery been loving it especially the weight

Super helpful! I just got a canoe with an electric outboard for the full family days on the water and have been trying to get some general idea of optimal speeds for distance. It looks like rebel batteries are all sold out, is there a different brand you would suggest with similar monitoring?

If the ReBel 100 ah is a Group 31, does it fit in the 106 MK battery box? I thought the box was a Group 27. Thx

Also from Washington kinda of confused about the trolling motor for kayaks do you avoid federal waters or are you registered just to avoid the headaches

Is the speed control on these kayaks accomplished with resistance or a pwm ?

Hi , really enjoyed the video ..what charger are you currently using for the Rebel ? Just subscribed!

Have you ever checked power usage during spot lock? How long can you stay spot locked?

Did you stop using the Amped Outdoors battery?

What is that red rod you are using? I love the bend in it when it gets bit.

Bought my Autopilot 120 a month ago and LOVE it! I also bought the ReBel 100ah battery. I downloaded the app to monitor the battery, but my screen doesn’t look like the one you show. Does that screen, plus the ability to lock the battery come with the paid version?

Where do you get your Old Town accessories from? I have checked their site and find nothing. I see your kayak matt in this video. Also saw your old town water bottle.

What charger do you use and where did you purchase it? Thanks for your input..

What charger are you using?

Potential range, psh! Get on the lake and start fishing until you get stuck on the lake. Sissy. 😏

The difference between common sense usage and hair on fire usage. Old(er) age has its advantages.
