- Hey! In this video, I show you how I made a big 72V 30Ah battery pack with Samsung 30Q cells.
This battery can deliver 2+ kWh of energy at a max of 80Amps continuous and weighs 10Kg.
Be Careful When Working With Batteries And High Voltage Devices
We display all the materials like the lithium ion battery cells, cell holders, nickel strips and assembly. This battery pack was made for a custom made 3000W ebike and is capable of a range of 60km.
Comment down below with suggestions, questions, or anything that's on your mind.
Hope you enjoy the ride!
Cells - 200x Samsung INR18650 30Q 3000mah 20A
BMS - tinyurl.com/bjwdjfkv
Cell spacers, nickel strips, insulation paper and heatshrink available at nkon.eu

simple and easy thanks
Thanks for the cad files. i subbed 😘
No problem, I'll share as much as I can!
Brutal, Afonso! Os meus parabéns pelo video muito bem conseguido e também pelas capacidades técnicas que tens para um projeto desta complexidade 👏
Muito obrigado Marcelo, é bom saber que começo bem ahahaha :D
Nice and good i like and i suscribe now😮
You don't have to worry about getting shocked at 72v unless you plan on licking the battery
Well you never know what people will be doing... jokes aside if you have sweaty hands and happen to be barefoot on a good ground I can guarantee you'll feel a slightly unpleasant shock :D
If you have cuts in you skin, you can feel 24v. Not too painful, but you will definitely know about it
Hey Alfonso! Great video! I just bought a 72v 3000w motor but I don't know how to calculate my battery :( It seems I need something to continuously draw 41 Amps (3000w / 72v) or am I wrong? Can you give me a tip??? Thank you! Thumbs up!
Hi Nicolas, thank you for the feedback! You will need something similar to that, most 3000w motors don't run at max continuous but it's always a good idead to size the battery up. If you're going for 18650 size like me, I suggest you stay above 6 cells in parallel unless you are running high discharge cells. Am happy to further help you with your project!
Great video, was wondering how many amp I would need for my 72v 5000w motor with 80a controller?
Thank you! It depends on how heavy the bike + driver weigh, the range you want and the lifetime of the battery. From my experience 110Kg bike @ 3kw I get 60km from this pack (30Ah). If you want around 50km at that power @5.5kw. go to (50Ah)
@@Asvybre Salut je suis du sud de la France 🇫🇷
Je veux construire une batterie pour mon vélo qui a un moteur de 72 volts 3000 w
En fait j’aurais souhaiter faire une batterie 72 volts 50 ampère / heures
Peux tu me dire quoi prendre comme matériel , c’est à dire cellules , bms,
Et aussi combien de séries et de parallèles ?
Merci de ta réponse je me suis abonné ..😊
Salut Louis,
Hope you can read in english as my french is not good...
You would do a battery similar to what I have done in this video but you'll need more cells.
If you use the same cells I use, 30Q, you'll need at least 320 cells for 50 Ah. This is 20 series and 16 parallel.
Use a BMS similar to mine and the rest of the components are in the description :)
Merci :)
hi, are you willing to share the 3d model? it will help me save a lot of time with my build (waiting for the frame to arrive)
Hi, I've now added a link to the OnShape files of the e-bike in the video description!
Hope it helps :)
@@Asvybre thank you, but notice that both cells link and OnShape link got link truncation from youtube, either use a shortened version or try to "separate" the link in two pieces, youtube sometimes does random things
You're right, I just noticed how it's showing up. By tomorrow this should be a clickable link!
Thanks for the feedback
Hi i am about to do the same. Is your bike the clone of bomber ?
Hi, it is a chinese copy of a bomber, correct!
Thank you for your efforts. I want to know if these frames support 20' x4 rims/hubs thank you !! the 199/20x2.5 are very expensive@@Asvybre
I am running 19'' with 2.5'' tires, kinda common here in Portugal.
But I can tell you from measuring my swing arm that I still have 35mm of space for more tire before hitting the swing arm.
From this you are able to calculate if the wheel fits!
over a $1000us for a battery pack? Where are people getting these so called cheap batteries? they must have jacked up the prices with these becoming the popular choice. All I can find is 4 for $28us
In the US I don't know the situation but over here in Europe there is a big distributor called NKON that has really good quantity prices.
