*Great little trolling motor **enjoyable.fishing** recommend had it hooked up to my 15 foot old town canoe and it pushed it pretty good with me and my son (220 pounds each).*
Fantastic... finally someone who can teach me how the assemble/orient the cells and where to spot weld so all the polarities are correct. EVERY other you tuber I have watched speed through their build assuming that the audience knows what they are doing. So thank you. I will now go and buy your book. 👍
Guys like you make life a little easier, before I looked at your channel I knew nothing about how to build batteries. Now I know a little more. Thanks!
I bought your book on building batteries. I can't say enough about how wonderfully you explained the process and theory for newbies and people with more advanced knowledge as well. Your videos are very poignant and interesting. I'd like to see one on building a RV house battery. Thanks again.
Thank you for your demo! Working on a boat project of my own and trying to keep it on a budget. This will help me do that! Looking forward to purchasing your book and the education
Man that was great ! Even tho you explain everything well... I still have not found a UA-cam video on these 18650 cell builds that explain the all important “what cell to connect to what cell” slowly enough for me to get the grasp. You all assume we have that concept licked and you race over it too quickly for me..! I guess I have no choice but to head over to Amazon and buy your book hey 😊 Thanks again. I enjoyed the video 👍
You are absolutely brilliant I wish I had the knowledge that you have right now I am trying to repair a e-scooter that was gifted to me. The batteries have burn marks on them so I'm sure they're no good no more The scooter runs for about a minute but not at full power and lose his charge really quick
Just finished my eBike and using LiPos for power at the mo. Santa should be sending an Arduino spot welder for my first battery build :) Thanks for the great resource.
You chose the right project for the 18650,cells. I can't afford 800bucks,for an ebike,but I already have a trolling motor, and some foam and gorrila glue so a fishing kayak is right in my budget
Great video Just what I needed to build a system for my bus. I am really started to get interested in trolling motor solar boats so just an added bonus Thanks
very cool as usual . hope to see Pops kayak on the water . Been thinking about getting a pedal kayak for a while for Mom , e-assist would be the Scheiße! 💦
thanks for all the info its my first time trying to weld and you may have answered my question /problem I have been having when your leads wasn't working I will have to check to see if im losing it in my leads
great video, thanks for sharing. How can I make that WITHOUT a spot welder ? And wouldn't you want to pack a temp sensor in thewre or is that included in the BMS ?
I want to do the exact same project for the same purpose, but I didn't realize how complicated it is to make these correctly and all the different approaches, sheesh!
Im new to this lithium batteries stuff. After watching your 12 volt lithium battery build you sprayed, wrapped and i think wrapped some more. With all of the insulation how does the batteries cool down or not get over heated or release battery heat? Don't a cool battery last longer. I guess 70 degrees Fahrenheit maybe?
Hi Micah, I made a diy rear hub motor ebike, and one of the item i bought separately from aliexpress is the panasonic 22 ah battery pack, hope you could show a detailed video on how to connect battery pack inside the hailong case. i really have no idea which wires goes to wich, charging port and wich wires goes to controller. and how to connect wire to the keys and usb port? thank you. i learned a lot from your videos.
Each of your video is very helpful to understand e-bike technology........ I have a question........ Is it possible to make a series connection between two or more battery packs where each pack contains a bms????
Thanks a Lot Mikey for enlighting us with your valuable knowledge on the Future major Transportation Power of this World ELECTRIC. I have gone through mostly all of your Videos. It was always something NEW I got to learn from your Educational Videos.... Thanks a Lot Mikey. Take Care Brother.......
I had some problems with a pack catching fire because I soldered in-between cells on the positive side and the Nickle melted through the plastic holder and the sleeve for the battery causing a short, this can probably mostly be blamed on my horrible soldering iron and thin as heck holders but since then I make sure to apply heat directly on top of the cell, at least on the positive side.
I have a 48v 1500w ebike and just finished most of the build and just wanted to know if I should run a fuse in between the battery and controller? by the way great channel
Hello, I have a question for you: Is it a good idea to put a 12v (4s) 14ah battery (ballance charged) in series with a 36v 14ah battery with bms? For a 52v 14ah pack. I've seen your video about making the battery bigger with a different bms. But i prefer not to take apart my 36v battery. (Sorry for my bad english its not my native language)
I've been doing this with a 12v 10ah and a 36v 8ah for about a year without any problems. it took my 250 watt ebike from 17mph to 23mph and I weigh 238lbs. just make sure your controler can handle the higher voltage. Also the battery will run down quicker but it's much more fun. Some people say its dangerous mixing battery packs but I've found that the 8ah batterys bms shuts down when it gets to the lower voltage limit which stops the bike so doesn't do any harm
@@Kris57277 No it won't, 2 separate batteries and 2 separate BMS's. As long as they are charged separately own their own corresponding chargers they'll be just fine.
Does the BMS regulate the voltage out? If you charge to 4.2v and discharge to 3.0v that is 12-16.8v... a huge variance and I'm not sure you would want to put 16.8v through your 12v trolling motor. (I'm trying to build a battery for my brother, so I am trying to understand what I can do.) Of course I can modify the maximum charge/discharge voltage, but then I lose a lot of my potential mah. Thanks for the great videos!
I noticed he didn't answer you after asking 1 yr ago, maybe because he doesn't know how to answer you. You are correct with your concerns. His pack is gonna cook that trolling motor in a heartbeat!
I had to scroll down for a half an hour to find your question. I have the same concerns - you are powering a 12v motor with 16.8V. My only solution is a step down dc regulator that is connected to the bms through a switch (switch is needed because regulators use up current in standby). So, basically, without a voltage controller, a 4s 18650 battery pack at 16.8v will work until the motor burns. Could be 2 hrs or 2 weeks
Can you put the trolling motor that he uses in a link? Also I’m looking for a flat battery pack to power the trolling motor; do you sell what you just made, I am interested! If not do you know anything that is similar that will power the motor??
Where do u get ur battery jacks so u can charge the battery and what charger do u use I would like to make my own battery, but my only problem is with what and how I'm gonna charge it I know u made a few videos but they didn't help me much
I use male/female XT60's and XT90's on mine. All up-to you as long as you can solder and use a multi-meter to determine polarity. Just remember to put male/female on the battery side and female/male on charger, output side. Wouldn't want you to short anything out.
Could you maybe also do a video on chosing the right controller and also panel/display? It seems that there are huge differences in functions, e.g. speed mode vs. torque (simulating) mode...
Hello, I am Cyrille from France. Thanks a lot for this helpful video that will help me to make my 4S18P battery that will fit for my 30lbs Minn Kota. Could you share the exact type of cells you did use ? I am planning to have 3350mA cells with 4,2A discharge capacity. Does that seem OK for you. I bought your book yesterday and even I am learning a lot I prefer asking questions before spending money in the cells 🙂
I have a 48v 1000w rear motor hub in which I'm using 60v30a(16s10p) to push it. The problem is that it's getting hot and, I guess, the magnets are swelling up(expanding) and causing the motor to seize up. Once it cools it will spin again. What's going on? Great vids by the way!
Awesomeness! I want to do this for my kayak trolling motor. I will probably use the VRUZEND battery connector instead of spot welding. Does your ebook cover this configuration? And I 3rd or 4th would like to see how you install the batt in the yak and see it in operation!
Ok. I need a trolling motor batt. I am also considering building an e-bike. Before I go down this path, can you give me an idea of how much money I will save compared to just buying a dry cell batt?

Love these videos. You made building your own battery look simple even with subpar equipment.
I would have loved to have seen the kayak in action using the battery power.
Hey, me too
That can be arranged
@@EbikeSchool cool, see you next time ✌️
@@EbikeSchool yes I was hoping to see it in action too!!!
Building one of these for my kayak trolling motor. Would like to know time of operation and at which speeds? Is he using a vfd?

This will help me do that!
Looking forward to purchasing your book and the education
Thanks again. Your book is very simple and it’s illustrations are understood and motivating 👍
Thanks for demonstrating the pack build. It would be great to see the finished product in use. :)
Your book on Lithium batteries how they work and how to build a battery was great
Your Dad will enjoy this for years
Nice build. Just what I wanted for my 12V toy car project.
You make it look so easy. I would be puzzling a lot more,where to connect the balance wired etc. Thanks for the vid,it gives hope.

Best way to explain how battery pack are made thank you sir.
Micah your one bad dude! Thanks for this!!
Quick and to the point video. Thank you.
Cool! Going to check out your Arduino spot-welder video!
Excellent job it akes time and dedication to produce these well informative video so I say thank you for your hard work it is very informative .
Great video
Just what I needed to build a system for my bus.
I am really started to get interested in trolling motor solar boats so just an added bonus

Excellent video and very well explained. Now please continue this project with a ESC/motor controller and/or something with a control panel...
very cool as usual . hope to see Pops kayak on the water . Been thinking about getting a pedal kayak for a while for Mom , e-assist would be the Scheiße! 💦
Hey Mikey, thanks for the video....I was hoping to see the kayak speeding over the water 🙄👍✌️😇

Is it possible to make a series connection between two or more battery packs where each pack contains a bms????
Are you not using the vruzend plastic caps now.?

Thanks for the video. It will help me with a 12v battery I am looking to build.
need to see how does it work , great videos btw
Hi Micah. What was the total cost of this battery? And weight? I hate carrying a 80lb lead acid or agm battery for my trolling motor
Can we use this battery also in our solar power?
please 🙏 I want to know more especially the ahms of the battery 🔋
Is 3.3 amps your maximum discharge rate turn 18650 cell?
How much did that battery cost to build. I am looking for a battery that I can use on my kayak, but dont know if I should buy one or build one. Thanks
You are awesome teacher 😍😘
Where do you buy the batteries? Any special place or brand I should look for?
Great video once again Micah! Thank you for taking the time and doing all of this.

Wont that mess with the BMS?

Do you worry about heat build up degrading the battery? Numerous layers of heat shrink plus 90 temps?
Thanks for your teachings! I'm hoping to get one day an electric bike for me. By the way, I'm still waiting for the electric motorcycle you started!
does the welder need to have the leads pushed up to deliver the current?
Yes.
Thats awesome i like to c u finish the motercycle
I like to know i bout solar panel and thanks for your book the help me alot fot lithium battery i buy for amazon

I need 2 of these for my kayak. How many pounds it weighs?
I’ve just purchased this book question? Soo wouldn’t fully charged the voltage would be 16.8 and not 14.4???
This is interesting as I want to build a trolling motor battery for my canoe.Thanks.
How is the electric honda conversion going?
Do you think shortening the cables would help?
It's quite possible, but I didn't have a wire cutter that could handle such large cables on hand.

Is the battery working on inverter 12v ?
Micah I am interested to make this. Can it be charged with a normal 12v car battery charger?
I am no expert here, just learning too, but I think that depends on the BMS spec and parameters :)
I have a 48v 1000w rear motor hub in which I'm using 60v30a(16s10p) to push it. The problem is that it's getting hot and, I guess, the magnets are swelling up(expanding) and causing the motor to seize up. Once it cools it will spin again. What's going on? Great vids by the way!
