DIY electric motorcycle 72V battery build (DIY E-moto Part 3)

[@skyguy4164]

I have seen many battery making videos. this one being one of the most safety oriented ones. others use really unsafe methods of connecting the cells, ignoring the possibility of error and so on. thank you so much for a good video!

[@mateng7707]

Sure, laying a whole battery pack on the bent connections is way safer than other methods

[@gearhed78]

You like those orange gloves huh.

[@andyfumo8931]

​@@mateng7707when did he do that

[@kendarr]

I love how every diy battery pack looks like a bomb while making it

[@jsnellink1990]

On that note. When fully charged, there is roughly 10MJ of energy in this pack, which is about equivalent to a Coca Cola bottle Molotov Cocktail :)

I love the simplicity of your videos, I just built my first mountain bike conversion and with your video on how to build power packs , I’m confident I can make a proper power supply for my 2000 watt hub system, I’m a subscriber and I give this video 2thumbs up 😊

[@cecilgibbssr.430]

I am planning on building a battery for a Viking Tandom Tadpole Trike my son and I built a few years ago. This battery with supply power for a Bafang 52v 1000 watt Mid Drive Motor I intent to purchase to complete our project. Your videos are highly informative as I am sure your books are even more so. Thanks for all you do for the DYI world.

I love all the videos you produce, whether building batteries like this one, or reviewing e-two wheelers. Keep 'em coming, please!

[@ericjacques3113]

I am currently working on a motorcycle conversion project. This video is gold! I will need to buy or make a 72V battery pack to get this bike moving and I plan to copy your work as closely as I can.

Can't wait to see the finished product because I've been wanting to do this for a while now¡! Thanks for doing it and getting all the important details right... That's helps alot. 😊👍🏻

[@clmetal2]

Thanks for everything you share, Micah! I am making a 10s2p but it needs to be layered (cube shape 2x5x2). Seeing you fold this with the plastic sheet in between answered my question

[@bluewanderer9903]

Hi Micah, I cant thank you enough, in 6 months time I went from total newbie not understanding a thing to a competent person ready to build my own ebike from scratch. Between this channel and EbikeSchool, your book and Vruzend there was enough material to keep me busy interested and learning for days upon end, and I enjoyed every bit of it and still at it. There is one subject that keeps eluding me and that is controllers, I dont know if you had that covered already on your channel I couldnt find it and I would love to learn a bit more about that. And while on the subject, what are the chances of you developing and offering a product like that for sale? Thank you.

[@D_Onibokun]

Hello Lynda, I'm a newbee to this thread and everything still looks like magic to me. I am amazed at your recorded successes. I wrote to the presenter but have not heard from him. Can I buy one sample of your own build 72V battery to help me "step by step" in studying the procedure as a newbee. Also, where can I buy all the required parts from? Where store sells them? If you send me your phone number I can also call you. My name is "Bill", I'm in New York and my email is [e-mail] Thank you.

[@bluewanderer9903]

@@D_Onibokun the only good way to learn about building battery packs is to buy his book, it is by far the cheapest, shortest and most safe way of learning ALL you need to know about lithium packs. It covers absolutely everything, from basics of lithium chemistries and different types to sourcing, ratings, building and construction methods, management, connections, charging, everything and anything to do with lithium batteries is covered in that book. Cheap too, best 20 dollars you will ever spend. Book is "diy lithium batteries, how to build your own battery packs" by Micah Toll , available on amazon, he has a couple of other good books too. Dont know what parts you are looking for but plenty of websites around the world sell lithium cells, one of them is vruzend.com or co.uk and they also sell some other great stuff like assembly kits for builings complete packs, bms, chargers etc. Read that book and watch few of the uploads on this channel and you will have no problem understanding where and what you want to do. Research and discovery is the next best part of the journey besides building, for me at least.

Hi Micah; Thank you for your videos and content! I own you battery DIY book, and I have read several of the chapters two-or-three times (I don’t want to set my house on fire, or hurt myself) but your videos “round out” the topics. A 20S12P, 72V 40 A hrs, 2.8Kw battery! Now that’s beefy! Thank you!

This is one of the reasons why I love your videos is because your awkwardness shows your a human that makes mistakes but awesome input as always

[@bridylph]

this is the future. hope lithium mining can become more sustainable for ecology and people.

[@username-rs4vf]

actually since lithium batteries are explosive if cut or damaged, people are researching new types of batteries with even higher energy densities compared to li-on. The guy who worked on the li-on battery helped with a new battery based on glass and sodium and it has 3x higher energy density compared to li-on. www.forbes.com/sites/unicefusa/2019/12/26/qa-austyn-weiner-in-senegal-with-unicef/#57ed73ae59e3

[@JamesWilliams-ji4mg]

Folding the pack over like that is kinda terrifying, why did you do it that way instead of connecting the 2 packs in series?

[@AimForTheBushes908]

He wanted tighter packaging due to the space constraints.

[@furqanandmatt]

Hi James. Didn’t really understand your comment. Maybe cause I’m a newbie. Could you explain further?

[@d-dogjackson7933]

Another CLEAN build bro! I used the 52v triangle video battery for a couple of my bikes and now I'm feeling the need for more speed & power. Gloves and the plastic cover while welding can save you a BAD burn so listen to him! I put the nickel strip on the wrong cell once and burned my finger almost down to the bone cause with electric burns you won't notice it till a couple seconds after its too late. Just be careful. I still get nervous building these things after that s**** so better safe than sorry, 72v will burn BAAAD

[@Star_Sn1per]

Now i understand why they charge 2000$ for these battery's

[@MrNobody_1618]

No I don't it look really easy when you know what your doing and pretty fast too !

[@bruhsanto8836]

convince and time

[@Real_MisterSir]

@@MrNobody_1618 first of all, you need to consider the basic cost of materials and battery cells. Then the manhours to build it, and then the final manufacturing that ensures minimal hazards for the user once they install the battery to an appliance. When you do it yourself you can jsut jerry rig whatever idiotic bomb you desire, but as an actual industry supplier you need to achieve certain safety standards. This all costs a ton of money, especially when you aren't a mass producing manufacturer. Price always escalates exponentially when you go up in size and complexity per unit.

[@Meonlymeagain]

What size of nickel strip did you use for the connections. Was the parallel strip the same size as the series strip ? Looking to do a similar project for perhaps a 150- 200cc equivalent. Thinking about a123 cells or using a electric car pack. Thanks. By the way did you ever finish this project ?

[@Zomby_Woof]

@@Meonlymeagain take a look at batteryhookup.com - they have a steady supply of standard new cells, plus a fast changing stock of salvage stuff from ev's and industrial recycling. Have to check frequently if you want to snag the best deals on the non standard stuff.

[@joeows6537]

20S12P with 200 amp discharge, 72 volts 36Ah ... I just purchaesed 3 of your books on Amazon... I am looking forward to building a battery for the Luna Galaxy Paint I'm gettin. Thanks for the video's.

[@Technoholicplus]

What about cooling, Sorry I am New, but i have heard, generally high drain batteries emits lot of heat.

[@computersfortheautisticfou9420]

I think he is placing it where the motor/gas tank goes so when it is in motion the air going around it will act like a cooling system but just a guess on my end

[@Doyle69]

12 Parallel, this configurations will help keep cooling down.

[@Yuricthebold]

I am sure whatever housing he builds for the battery will also channel air flow to assist with cooling.

[@davidwho8215]

Nice job

[@jeffbeasley8235]

MJ1's are not high drain cells by any stretch. Also, with this hexagonal packing scheme, the batteries near the center of the pack will get a lot hotter than those on the outside. That's of course dependant on how much power is charged or discharged, though.

Hola Micah, Merry Christmas to you and yours, I've made it just under the wire (11:27PM 12-25-19). Glad to see you back, healthy, wealthy and having fun. I have 3 words;eHONDA eHONDA eHONDA!!!!! Really want to see this project's progress. This video is a great continuation and contribution. I'm more excited now than before!!.I don't like the look, or how NOT nimble they are, but for $500, I couldn't pass up an eDrift Fat Tire Scooter. It needs a larger pack than the 60V 10ah Li-Ion it has at the moment, so this video may be instrumental. Do you have any thoughts on overvolting that eBike's 1500W Brushless motor's speed controller? BTW; something I've been doing to my 57V (soon to be 61V) "Vruzend" packs, since I live in So. Cal. ie the Mojave Desert, is NOT completely sealing the battery packs I build. I leave 2 sides open, so there is airflow through the pack. On my little 32mph 750W Brushed Motor CURRIE Schwinn "TESLA" eScooter (stock was 36V/15mph), I also drill out/swiss cheese the bottom floor of the battery case, so air can get up into the pack and add even more cooling. Even in the 90-100 degree temps that I've run my eBike packs in this last summer, none got over ambient temp and my packs are as strong now as when I built them. Just a tip that I hope may help for those of you in hot climates. Now, heat shrink is cheap, so for this cold(er) time of year it's easy to seal those battery pack sides up & the holes in the battery tray and allow the packs temp to stay inside to help keep the pack warm as well. Then, just cut the sides back out for summer and only do the reseal job once a year. Thanks in advance.CheersBoots LangleyLa Mesa, ca.PS; Hey, I have a decent Resume myself;Mechanical Design & Machine Drafting (2 yr Tech School Degree), a lifetime of Automotive/Motorcycle Service, Repair & Restorations/ Racing , including several years as a Technical Editor (Cordura Publications/ Mitchell Auto & Truck Repair Manuals).

Also If you are ever considering building one of these and cutting corners and just soldering with a $12 iron and wire, think again. When you finally get the connections right after 14 hours of struggling they will come apart during your travels and you will kick yourself, have to rip the whole battery open and redo until you finally just get fed up and buy a spot welder. Take it from me I tried to cut corners and it cost me days of extra work and extreme frustration. Time is as important as money when building these things
