Pouch Cell Vs Cylindrical Cell Batteries - The Facts with Bruno POWEEER

[@topelite666]

I didnt learn much about pouch vs cylindrical batteries here but i did learn how invested ebmx actually is to serving their customers. Very impressed! good job!!

[@antssta]

As an Early adopter I can happily say Ebmx and there battery is legit ⚡️

[@dimitris000bourgos]

what batteries are beter for scooter 18650 or pouch cell of ncm 72v55ah

[@RP-xb3vh]

I literally just ordered the same battery from you guys today! Looking forward to the BIG POWER!!! ⚡️

[@jimlahey5354]

How long did it take to get it, and how do you like it?

[@progressive_e]

Awesome video boys!

[@jamiesymons3407]

Can't wait to get mine next week Yeeew!!

[@stevenash7476]

so my time et velimotor vmx12 has a good battery thats before its time with cheep parts. for its size its ground breaking

[@xboxice2005]

Good on you EBMX and Broono.

[@JWest1]

I am looking for a supplier for NMC pouch cells, I am going to be building a 20kwh battery for my motorcycle conversion. I want 300 miles of range. Any chance I can get a link to buy some of these cells that arent from China?

[@joshlaflamme567]

Any plans to make a battery with a better bms for higher output? 72v 57ah is enticing but limited by bms to 125a

[@salesebmx4696]

ooh yes we have and its close.

[@jimlahey5354]

Love these videos. Keep up the good work boys. These batteries look so much better than the chai battery. However I noticed the Chi battery now has a display that shows amp hours, watt hours, etc. This is way better than a voltage-based state of charge display.

[@christianwagner6244]

I work in battery testing and usually, especially due to heat differences, pouch cells tend to bulge/swell more than cylindrical cell do (we actually run tests called "1C swelling" ^^). Is the potting not preventing that, causing higher internal pressure? Or is the potting material able to compensate that? A teardown/build video would just be amazing but anyways, thanks for the effort you took on creating the best aftermarket batteries for surron!

[@BrunoPOWEEER]

The main difference comes down to the cell quality… just like any other thing, cheap pouch cells are rubbish, premium pouch cells are amazing! Good quality cylindrical cells are accessible to any small business and DIY community but premium pouch cells are restricted to large scale business. The better the cells the more documentation and minimum order the premium cell manufacturers require from the business trying to buy. Basically all premium pouch cells that I’ve ever worked on multiple projects for multiple companies they just don’t swell/puff even if they’re not compressed. Unless they’re very abused but even in that case I only saw a few cells out of thousands losing the vacuum but not puffing. Steel case and potting are an additional mechanical barrier protecting from penetration, dents and of course keeping the cells compressed as well =]

Thabks for sharing your experiences Bruno =] I've read your reply to Evfreak's rant against pouch cells aswell and you couldn't said it more clear, yet still polite :D

[@user-eh5cr4or6k]

@@BrunoPOWEEER cylindrical cells have over 25 years of longevity pouch cells nowhere near that not to mention as someone else said they are prone to swelling and I'm going to go out on a limb and say that's why you're only given a two-year guarantee on a battery the cost of which should come with a 10 year guarantee

[@Etienne85]

​@@BrunoPOWEEER Interesting to know these premium pouch batteries are not available for sell to all customers. Unless we repurpose a car battery to extract their premium pouch cells and build another battery from that? :) Wondering if that would work

[@JoLe1991]

I have a Microvast NMC 13S 21Ah pouch battery with a very long rated cycle life (3000-5000), and the voltage sag under load is impressively low, about 0.7V @ 1C. any cylindrical cell battery has more than twice the sag, and definitely not the cycle life. the challenge is for ebike (pedelec) batteries, the geometry of pouch cells requires a custom made case that will not fit in tight frames. welding a custom case though is absolutely worth the challenge for having an amazing performance battery to last and last

Ok, so why Tesla choose Cylindrical cells instead Pouch cells?

[@jimlahey5354]

I think Bruno should legally change his last name to Power.

[@keokio7]

pouch batteries were always synonymous with lipo. And those lipos were always abused because of their high discharge ratings of 25C+. Probably why u see so much puffing, and why pouch batteries have such a bad rep. I'm no Tesla engineer but i think they stuck with the cylindrical cells because they wanted to use the cells as part of the structural integrity of the car. anyways informative video on the batteries, i'm a believer now in pouch cells, as long as they are the correct chemistry (and not fake) lol.

[@T-Sav]

What are the specs of the pouch cells used inside?

[@bassrush5102]

72V 42Ah 6C discharge, 1C charge 60V 53Ah 6C discharge, 1C charge both have a lot of headroom when considering everybody is running a max. of 15kW on controllers, because the motor can not make use of more power. both bigger batteries have even more headroom, as all 4 of them are 6C discharge 😄

[@jimlahey5354]

Really curious what is the internal resistance of one of these cells? Knowing this one can calculate the power generated by these packs at a given current.

I hope you can ship to New Zealand bro! The battery

Soon get a battery but I want 60v 63ah 🙂

[@salesebmx4696]

we do a 60v 65ah now for Surron too :)

[@BrunoPOWEEER]

So much POWEEEERRR mate… 😮😮😮😮

[@user-eh5cr4or6k]

@3:05 if pouch cells were the end-all-be-all then the thing you're not mentioning is why isn't Tesla going two pouch cells instead of coming up with a new form factor for a cylindrical cell?

[@EBMXtreme]

We can not speak to the decisions that Telsa has for not using pouch cell yet, however many other car manufactures are using pouch cells and having great success with them.

[@DaveElectric]

Because to have a high range EV you need to have a low C rate operation. For example, let's say you want a car that runs for 5 hours. To run for 5 hours, your effective C rate operation has to be 0.2C or less. Pouch cells are typically rated from 8C, to 15C, to 25C, to 50C, and higher. Let's say you ran a 10C circuit. 3600 seconds / 10 = a motor operation of 360 seconds or 6 minutes. That's it. You can't run a daily driver vehicle at that C rate operation.

[@kiwilife3789]

These are all made in China are they not?

[@je7647]

When you order them worldwide they are shipped from Hong Kong 2 weeks later from what I’ve read. Make your own it’s easy
