Battery was a bomb waiting to go off. And the vendor has full responsibility. If a buyer can't trust the seller where is the market. Artur made a huge mistake. Own up and move on.

Every battery builder I ve spoken with has concerns at the least about the build . All would never sell a battery built as yours is. No matter how good or bad the customer is the battery is still a bomb.[pre][/pre]

I don't know how big is your experience in battery building, but I have same battery for over 2 years and over 250 cycles.. so if you are saying the batteries ate the time bombs - yes, but then all other batteries are bombs as well. What test do you want me to do to prove you a durability of it?
I am ready to sacrifice one, for the benefit of our ebike community and my clients.

tomjasz you are talking BS... timebombs oh my god 
i build thousands of these batteries for ebikes and never ever any bike catch fire or explode before.

Look at the photos of the battery and the result. I never said all batteries are time bombs. Mind all work fine , more than a dozen, some by me. Great builders have reviewed and pointed out serious deficiencies.steam25 said:tomjasz you are talking BS... timebombs oh my god

yes they pointed it out. and STILL not one of many thousand battery have failure before. if batteries build like this, really so horrible, why not even one of them show any problem?
if you take a tesla battery and smash it with a sledgehammer it will catch fire too. it all depends on how you treat it. if handled wrong then any batteries are timebombs
what i mean to say: if you KNOW these batteries will shake around crazy inside of a offroad bike. then just SECURE it in the correct way

i will take one of those nickel strips and make a current test again. this stuff is oversized and double layered. you can put 300 amps throught and it wont get barely warm. from the photo your "specialists" cant see that.tomjasz said:

Man how posters go from a few builds to hundreds always amazes me. Show you battery builds and factory? I admit I'm always learning. But buyers should not be sold battery by vendor who is learning, unless they understand it may not be a professional build. There's enough reviews to reveal this one wasn't.
End thread for me. Smart money will look to another builder. The AU guys have some far better builds and designs rolling out.

Enough of this shit talks. I asked moderators to stop this guy to advertise other manufacturers in my thread! I would understand meaningful critics about battery design , like some other battery builders posted here, and I appreciate it, but this.. other then Haters gonna hate , I don't know how to name it!

Now with photo's of the damage. I believe this is the customer you asked about? (NTDWM)

As has been discussed a number of times over the years in various threads, a thread outside the for sale section is not "your thread" to prevent others from posting relevant-to-discussion information, regardless of who made whatever it is they're posting about.Artur said:
It is only against the rules to do that within your for-sale-section thread.
If you want to claim this is your advertising thread then it can't be here in the discussion section, and must be merged with your for-sale thread in the for-sale section, otherwise it is spam, which is itself against the rules.

Talking about battery of that guy:
June:
September:
3 month time period and it is on same level prety much..
Do you think broken battery will be at the same level after 3 month of riding?
thank you!
p.s. I think 300a is a bit too much we dont use over 100A, and it is just for 3-4 seconds..

my eyes only can see one layer of nickel, and i doub't that you are able to weld any nickel strips (with normal shape) thicker than 0,2mm onto those Panasonic PF Cells.
to "300A it wont barely get warm":
considering that you mentioned you are a battery manufacturer who has sold many thousands of packs, it makes me
tomjasz said:
Nah we dont know exactly what was wrong with the battery.
We can discuss that the build wasnt optimal, but i dont see any MAJOR design issues.
Of course i do much more serial connections (one for each cell) and only a thin parralel connection, but since cellgroup 1 was drifting, i guess the design was not the problem.
Maybe the cellgroup had a damaged cell or what not.
I guess we will never know.
I also dont get the story 100% right so far........but dont have time to read everything either.
Battery was unbalanced since day 1 or not?
If so then return the bike and dont try do tinker on a 6000€ bike which is inside the warranty.
I also never said that this is the best solution for the vendor to protect his/her image, but in germany you have guaranteed 6 month of warranty.
After 6 month, YOU, the customer have to prove that the issue was existent since the date of purchase.
Of course Vector have to decide whats the best solution to protect its image and i dont know their warranty conditions and length either.
Law says 6 month guaranteed. .........if the manufacturer offers more, than they have to cover it.
Vector did the worst thing you can do.......let the customer tinker on the defective bike.
For me its no problem to check a battery, others dont even know what a single cell is........or a cell group etc.....or how to measure its voltage....what drift is dangerous and what is normal.
So the right way would be:
Defective item inside the warranty time > return to the vendor > check and repair and make it idiot safe
You have to make this shit idiot safe and not let the customer open the bike and fight with connections and cables.
But on the other hand, i had my experiences with vector too and decided to also repair it by myself, cause artur did everthing to prevent me from using my right for warranty.
But it was only a defective sealing on a new, but horribly packed motor, so i decided for me to take the short way.
A 6000€ bike is a complete other story.
I wouldnt ride it 1m with that cell drift and use my warranty or send the lawyer to vector.
Same with a defective controller.
If i decide to tinker on the bike by myself, its my mistake.
If i claim the issue 6 month later, maybe its to late........
Law says after 6 months the vendor is quite safe......if vector offers more, i completely turn my statement into the different direction.
Then vector have to cover the whole price for the bike.

relax madin, of course i am talking about peaks of 300. no you cant discharge the whole battery pack with 300 amps and it barely gets warm. come on guys. dont change my words to fairytales, we all know thats impossible.
i will do a video when i have time with a adaptto realistic kind of current and some higher peaks.
what i mean before is: i tested similar packs with currents over 120A for longer periods of time and the whole battery pack doesnt get barely warm outside because the nickel was on fire or something.
but yes, if you rape a full batterypack empty with 200+ amps it will be hot.
i dont want to offend anybody here but some people make it pretty difficult in the forum to argue about something. they build 1-2 batteries in the life and try tell me how batteries should look like because they post a photo of them in facebook or something. topic was that artur asked what we think about this situation and what to do. i tried to say that its highly doubtful the battery catch fire out of nowhere because some nickel strips are too thin after 6 month of riding. not more, not less. but as usual things got out of control pretty quick when people have other meanings. i hope we can calm down a bit now since i made things clear. madin dont cry, its ok buddy :wink:

Instead of getting cheeky, you better recognize the flaws!!
you knew almost nothing about how a battery needs to be build for ebike usage, and absolutely nothing about the importance of equal current flow through every single cell (especially at such high discharge currents).
you ship out unbalanced packs according to the owner of that bike

wait what? when do i say i ship out unbalanced battery for this owner? i never talk a word with that guy. 
you mixed something up here i guess.
