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

Great video Micah. I learn more from you and your battery build videos than anyone else. You actually teach by explaining each part of the process. Great job! Thanks!

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 😊

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!

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!

I can't thank you enough for these videos, just picked up your book ultimate DIY and just finished my build, thank you so much Micah!

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. 😊👍🏻

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.

@@BillOnib 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.

How did you learn all about electricity?

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.

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

this is DEFINITELY something I wish I had started learning a long time ago

Really interested to see what your typical range and max speed is on this build.

This was awesome Micah. I have an ONYX RCR with a 72v setup, been thinking about making a battery for it eventually. Really excited to see your motorcycle progress.

I like how you clearly detail all your work. You the best!

I cant wait to see the top speed of this thing! my brother in law wants to build one now! LOL

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).

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.

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

@@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.

Great instructional video, I’m also working/planning on building my own 72v lithium battery pack for an electric Chinese bike that I salvage but it instead had lead acid batteries which are completely dead and can’t hold a charge. Hopefully I can start this project before the summer begins.

So much welding... Great job staying focused and safe!

Nice. I am going to school to become an electrician and I just found your channel and it is very interesting. Cheers.

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
