Honestly looking back, every battery I've gotten from all ali express has exploded
And every battery I get from em3ev lasts several years
https://youtu.be/wgFLYGOJJTc
This was not even on the road, this was me testing the wheel in free air right after turning it on
That was a mostly peaceful fire though. it gave out two or three puffs, and the fire extinguisher put it out. no large explosion
You would think at some point I would learn to not buy anything from any vendor that sells batteries on AliExpress
I remember that video
@larossmann Welp, you do you. Just keep us updated on the drama, lol
read. instruction. and. understand. them!
i now know why i screwed up my tube patches
turns out, you put on the glue
wait for it to dry
and theeeennnnn you plop a patch on
i just put a lot of glue and poped the patch on, after that i held it down hard for 10 minutes until it dried lol so that why i was never able to patch my tube
atleast that what i think was the issue
@Naz. That Guy you also have to rough up the surface and clean it off, but yes, that thing with the glue is very important
yeah i did that, sand it and clean it
"Louis,
Unlike lead-acid batteries, lithium batteries can not be used in series or parallel, which may cause problems during discharge or charging."
..
?
Haha that means their packs can only contain one cell
> "Louis,
> Unlike lead-acid batteries, lithium batteries can not be used in series or parallel, which may cause problems during discharge or charging."
Lmao
Funny, cause lead acid batteries even get charged the exact same as lithium ion: CC/CV with low current shutoff (hopefully)
@larossmann They can be run in both series and parallel, though for series you'll want a bypass diode to keep from exposing any pack to more then 0.6v reverse voltage
(more to the point, prevent exposing the BMS to reverse voltage, when you get to the undercharge limit and one battery 'turns off')
#break-it because the sanity of Louis is being broken by these people
This will only make for a better final video
@larossmann lol I was checking your channel just today for a new li-ion video
do make sure to let me know when you post it
They are so full of shit. I think they are digging their own grave with these statements.
I don't think they care at all. They will change their company name and be back in business after a week.
wait larossman are you the guy who fixes phones and all that and hates apple?
No he breaks android phones and loves apple /s
whut
Yes it's the youtuber
: O
@larossmann I think it's mostly translation errors, not going to lie
They probably mean that they don't officially endorse putting packs in series and in parallel
Doesnt matter what they 'endorse', if there battery explodes when used within the rated current charge/discharge specs, its 100% on them
^^
I'd be shocked if they tried to pull a name swap though. For better or worse, UPP does genuinely have a reputation, and they've been around as UPP for years.
Yeah
I'm really looking forward to seeing how they continue to handle this.
Or continue to dig their own grave. Whichever ends up happening.
Definitely a double edged type of situation
if mainstream media decide to pick up the story
you can bet the narrative will be "omg lithium batteries are all bombs, ebikes are unsafe"
rather than what it actually is about
I don't think UPP will change their name either
they aren't a fly-by-night operation as much as their attitude makes it seem like they are
I don't see it ending in total catastrophe for ebikes or DIY, even if the media does decide to go ham on it.
We've still got hoverboards. :P
Exactly.
Yeah, I just always fret about bad press for ebikes
it always comes with the risk of some knee jerk legislator making things slightly more annoying
Yeah, that is always the concern.
But at the same time, if this wasn't a one-off and UPP really is putting out shit packs despite their reputation, they need to be forced to deal with that.
I agree
(Disclaimer: I still haven't sat down to watch Louis' bike autopsy vid)
I just wish there were a way to reconcile both concepts
Found an UPP battery on aliexpress that claims cell level fusing
They've been claiming cell level fusing since around the time that house burned down.
Maybe they actually have it
Before then even
it's been like 2-3 months
The incident I'm talking about was around a year or two ago
Oh that thing
‚ÄúSeiko IC BMS‚Äù
UPP having cell-level fusing was a frequent topic on the server mid-late last year, iirc
I still haven't seen a UPP pack teardown that showed the cell fusing (though I haven't especially gone looking, to be fair)
I don‚Äôt think cell level fusing is all that necessary anyway
It's very situational, but it certainly can be. It prevents a single cell short from draining / overstressing the rest of the p group

@StarTrak @StarTrak that is what makes me sad is that that will be what happens
I wish we could call out bad manufacturers without people immediately tarring the industry
I am hoping I can get them to pay for something without releasing it publicly.
They were very, very agitated about the video of the fire on my girlfriend's 2k subscriber channel.
they said we'll cover you, please just take it down
i said fine, let's talk.
I'm sending them a link to mine on the 1.3m channel if this isn't resolved over the next week or so. and let them decide what they want to do from there.
@larossmann What where your actual losses due to the fire?
haha
Startrak: Pretty much. not looking good for UPP.
That video was uploaded 10 months ago? Sorry for butting in but why does it take long for vendors to respond? I thought aliexpress had good buyer protection
Different video of a different fire.
The fire with the UPP batteries was quite a lot worse.
Oh right
that was a mild fire.
i had a fire extinguisher next to me
that was a fail though
i plugged it in and it went on fire right after i spun the throttle.
the bike was fine though. i put my em3ev battery back on that bike and rode it home after cleaning it off so it didn't smell
my em3ev battery has been bullet proof. i did add some thin rubber to take up any jarring impacts from riding on the lunar surface we call ny. i kinda wish i went with the triangle but only had enough for the jumbo shark. with the abuse i put on my bike im suprised the only thing iv broken so far is the back hub/freewheel (which is like 4+ years old and sat in a garage for 3.5 years lol)
I sent them final message
they were the ones that asked me to remove the video, i see no reason to remove it at this point
what did you ask for?
money to pay for what went on fire

Honestly looking back, every battery I've gotten from all ali express has exploded
