SHENZHEN FACTORY TECHNOLOGY battery packs- is it real?

It falls under the same thing I have done with older cars that are modified with a different engine.
Building fast ICE cars is something we are all familiar with--not scary at all to most (although they should be). EV battery fires, on the other hand, are already feared by many. Just look at the coverage every single EV fire gets, despite the fact the ICE fires are five time more likely per mile driven than EVs. If we do get EV fires that can be traced to modified packs, I expect that eventually EV inspections will include verifying the pack is not modified, and EV insurance will also require showing pack is not modified. Time will tell.
 
I recently bought a 50kWh kit from VIVNE (Shenzen Factory), going to use it on a e-nv200.

I guess I'll have to wait like a couple of months until it arrives to Barcelona (spain). The kit comes with an original reprogrammed BMS and all the cells are from CATL.

I'll keep you updated
 
I can see your point. I rebuilt a Pontiac Fiero in 2015. That car had less than .05% of the cars catch fire in the 80s due to an engine failure/recall and the car is still known as the car that "catches on fire spontaneously". No way to gauge where public opinion and regulations are going to go in advance...
 
I've been watching this thread to see people's experience with these replacement cells as I have a ZE0 with 55% SOH that I will eventually replace.
There is some risk involved, that will always be the case. But it is not a complex problem. Current LiFePO cells are safe and reliable. It feels like the issues raised within this thread are simple teething issues. And they will be solved. I'm just waiting for the 50% SOH trigger to put an order in for one of these kits.
 
I just wish Nissan or AESC would make a repack kit.
Neither will likely do that. liability lawyers in both companies would be a vote against. The fact is that very few percent of Leaf owners would be willing to shell out for a new "re-pack" of the original cells, if upgrades are done then they would be "on the hook" for the quality of the Canbridge and program.
There might be a case made, for a company that could buy up spent Leaf's and re place battery packs on a large enough scale to interest the top end battery mfg.
The problem then becomes can the re-sell the referbed car at a profit while competing against the cheap used Leaf's on the market? My guess is no, at least at present.
 
What I am imagining is that AESC/Nissan (who have made the leaf cells/modules from the start) would crank out some 40 kWh modules, an updated LBC, and a firmware update for the VCM so that owner of 24 kWh vehicles can just have a shop repack the battery. All certified by Nissan like any other repair part. Car makes do something similar with crate engines, Ford Chevy Chevy even does an Ecrate package of electric motor and batteries. https://www.chevrolet.com/performance-parts/ecrate

I think at 250$ to 300$/ kWh Nissan would make a profit, and do a lot to buff up their image in my view.

But I do appreciate your idea of scaling up a remanufacturing line. Sadly--the world doesn't really care about rebuilding things as an alternative to new build. Unless its a B52 or something like that.

Unfortunately it’s not that simple, LiFePO cells operate at a lower voltage, simply building a pack like this would require a whole new BMS among other things. I’m afraid NMC battery tech is what is safest when considering any aftermarket kits for the leaf. I have a ZE0 with about 41% SOH and 22.5% Hx I’m right there with you when it comes to needing a replacement. All I’m saying is, do the appropriate research before taking any action with your own vehicle, you don’t want to mess with too many variables.
 
2024 now. I have purchased similar from YASTE, hoping to pickup my battery this week.
Can you update on your experience?
I will be self installing, purchasing insulating gloves etc. don't mind admitting a little scared as my industrial experience has both prepared me for this and provided sufficient knowledge of the risk to not be complacent.
I am considering the same. How was your experience? Installation directions clear, product works as promised?

All of these installs have some kind of quirks upon installation.
Have low expectations and have lots of room for "looking the other way" when it comes to anomalies on the dash, hiccups in installation process, incorrect or confusing directions, head scratching quality issues, etc.

Most of the things are not complete show stoppers, and it is within the realm of what is to be expected in race-to-the bottom pricing for this kind of product.

Be realistic. It ain't gonna be perfect. Come on, you already know that, right?

If you are going to be nit picky and demand OEM quality and standards, these products are not for you.
Seriously. Don't do it if you are in that kind of mindset.

If you are willing to risk getting a dud, don't mind having some weird behavior at times, are ok with having some down time while sorting through issues, and can be patient with customer service that is half a globe away, you'll save some money and be a test subject that others can watch.

When it works it'll be great. When it breaks, it's gonna suck.
