DIY 72v 60Ah Battery Pack For 2000W Electric Bike

Hi friends today I am going to show how to make electric bike Battery pack at home.
Here I used
1. 240 Lifepo4 cell (3.2v ,6000mAh ,2000 life cycle)
2 . 24s , 50A lifepo4 battery BMS two port
3. Battery holder
4. Epoxy Resin board (yellow one)
5. kapton tape
6. H shape Nickel Strip
7 . PVC heat shrinkable tube battery cover ,etc


Thank you for watching .

List of take home for peeps copying this video:

1.Spacers are crucial, keeps the system strong, but also separates the cells in case of casing failure.

2. Polyamide tape (Kapton) across the rails before insulating the entire layer with strong layer of insulator.
If the insulator fails the tape will be a last line of defence against up to 1000amps shorting through your battery,
remember a lithium cell has more energy density than TNT and will go off with a BANG.

3. BMS; DO NOT SKIP THE BATTERY MANAGEMENT SYSTEM. Don't cheap out either, it will determine your battery longevity, performance, and safety.

4. A strong ideally watertight casing is very nice to have, especially if you intend to use it where it might rain or get wet. It won't survive being submerged in a lake, but some rain or just washing your vehicle with a hose should keep it alive. Glued together heat shrink sheets is perfect

5. Something not mentioned here but calculate your current draw and work it out across the cells in parallel to get the per cell current. Make sure your nickel strips can handle this current safely, if not get thicker strips, or wider, or spot weld on extra strips.

BONUS:
I feel like I shouldn’t have to say this, but you can't substitute spot welding for soldering, you may pop the cell and get very bad burns.
Solder to tabs, not to a strip directly on the cell for the same reason.
Solder and Heat shrink ALL wire terminations or joins.
Safety is not optional, please be informed so you can be safe

Great job using lifepo4 instead of li-ion.Much more lifecycles.This weight more then 35 kg on pure battery. Lifepo4 32650/700 weights 141-143grams each x 240 pcs lol

That's an arc reactor.. Tony would be proud of you 👍

I know no one will make this battery but like for this guy's hard work.

Finally found battery in my JCB, truck thank sir😊😊

[hansmontenegro]

Great. Can you tell me what charger do you use to charge that battery?

[Paul_Bearden]

Gluing heat shrink sheets together is genius

[mmoci]

Wow, totally interesting. What kind of spot welding tool do you use and how tick those strips for cells should be in a such a large arrangements?

Amazing,
Thank you so much for sharing 🌹🌹🙏🙏

A vida útil das baterias de lítio sendo usadas em cargas iguais a motores não tem vida útil muito prolongada acaba ficando extremamente caro esse projeto.

A lot of DIY channels that I see kinda just haphazardly throw together a battery pack, you actually did stuff a lot better than them.

3 gros problèmes :
- Le coût
- Le poids
- L'encombrement
À partir de là, tout est remis en cause.

Wow tôi cũng đang tìm kiếm kiến thức tự làm Máy hàn cell pin !

[chadtine]

woow nice...
what kind of glue did you use in pvc shinkable wrap? thanks..

[ElevenShop]

That's some great content and production value. That kit looks great.

In life there is indeed very much that we need to learn for the advancement of our life on this planet earth that we love so that it is more durable and does not quickly become porous and dull and full of dust.

nice build... wuts the weight?
1 thing im inclear about with these batt packs... could i buid(buy) several packs (each with its own bsm) and connect them in searies/perallel like a lead acid batt.? and charge them with 1 charger{ ie. solar).
or with a solar charge controller, do i need a bsm?
