NOAH'S ARK: Index of LiFePO4 cell manufacturers

Narada produces their own LFP cells, they are like BYD, their cells are supplied only to their own projects all over the world. Their solutions and batteries are more famous worldwide. Now they begin to supply their cells for their clients for customize their own batteries.

We provide LFP cells to our clients in automotive and energy storage application. Narada is one of the suppliers. That’s how I know. Just for your information if you think it is helpful for your list.
Thank you for the reply, and for contributing to this discussion. Do you have a datasheet for a Narada cell that you can share? What is your opinion of them?

Also, can you please add your company affiliation to your profile (if you go to 'account details' there is a section for a custom title, this is a good place to include company affiliation. Thank you.

REPT does look to be a legit and fairly new (<5 year old) manufacturer. Topband I am not sure about. Their website strongly implies they manufacture things, including raw cells, but then I've been trying to vet this stuff long enough to have seen some pretty slick websites with factory assembly line photos, certifications, company histories, board of directors bios, etc, that ended up just being grey market resellers masquerading as manufacturers, which makes me fairly skeptical/cautious/cynical. You may well be right that they are a manufacturer of raw cells. Usually I like a couple pieces of corroborating data apart from the company themselves, and so far I can't find anything about them that doesn't originate from them. I am going to see if I can do a little more digging, and I am also reaching out to them for a datasheet and a couple other q's
I'm doing some more digging as well. Battery Hookup was selling the green Navitas 25ah cells, I was told that those were manufactured by TopBand, but when I go to Navitas's website, they claim that they manufacture them themselves.


Maybe they bought the 25ah cells from another supplier before they started making their own.

Also, it seems that Navitas is, in fact, manufacturing their own cells now. Maybe a new add to the list.


I just sent Navitas an E-mail asking about the origins of their 25 amp hour cells. Will report back.
 
RE: "REPT"
Company name: Ruipu Energy Co LTD
Alternatively: REPT Co LTD
Largest Cell: 280Ah is the largest I can find specific information for, though there are some AliB references to 302Ah.
Company Website: chinarept.com
Website shows raw cells, modules, rackmount, and EV type packs. (here)
Website states they began in 2017, and are in the 'top 12' in battery shipments as of 2019
Press release picked up by yahoo finance (not sure if yahoo does any vetting or not)
Second news story mentioning them here
EV Lithium has a page on their 280 cell as well.

This is enough for me, I will add them to the list

Maybe, but I think I am maybe not being clear enough that the bar for inclusion in this list is high, the original purpose of the post was specifically to try to separate the actual manufacturers from the rebrands and such, as such the bar of evidence is high, because the original intent is to separate the actual manufacturers from the dozens of companies that misleadingly call themselves manufacturers. My learned skepticism with this market leads me to give very little weight to whether a brand says they manufacture their own cells or not, without corroborating evidence, that on its own is barely more meaningful than whether they say they are Grade A or not.

As your inquiry into Topband, Navitas illustrates, its sometimes a little like a russian nesting doll when trying to figure out who manufactures what, who is a brand or rebrand, a seller, etc. In many cases they are truly manufacturers, in many cases they stretch the word manufacture (ie they assemble packs, or they wrap cells and drill or weld the terminals, and in a few cases they just outright lie. If you look at Alibaba sellers, one commonality between many of the resellers, the actual manufacturers, and the companies that fall somewhere in between is they all will have a bunch pictures of big business and manufacturing campuses, lots of shots of workers in bunny suits in labs and factories, half these companies are using the same bank of stock photos as eachother. Not saying this is true of topband or navitas, but I'm also not saying that its not. From what I recall, even Amy (Shenzhen Luyuan) had language on her website at the beginning implying they were a manufacturer.

I look forward to seeing what you unearth, and what the company says, and if you can find enough info on one or both companies, I will include them. One possibility is that these (Navitas, Topband) could be two names for the same thing (one brand name and one company name, or the strangely common practice of Chinese companies having 2 or more company names for the same company (for instance, best I can tell, the company that makes the JBD BMS goes by 3 different names ('JBD Battery PCB store' on Aliexpress, 'Dongguan Jiabaida Electronic Technology Co.' Co on Alibaba, and 'Shenzhen LLT Electronic Technology Co.' on the web..))

EVEEVE Energy Co., Ltd

EVE has offical online store. Preferential price, faster timeliness, more guarantee.
I would like to share the website address to you if you are interested.(DM me)
I tried buying from eve directly before but communication was very difficult.
 
The company name is THUNDER SKY WINSTON BATTERY INCORPORATION COMPANY LIMITED
THUNDER SKY was founded in 1998 by the founders who created the WINSTON under his own name later on. In 2017, the two brands integrated as one called THUNDER SKY WINSTON BATTERY.
I suspect this thread has been targetted by spam or scam bots of sorts?
 
there is also naradapower, which was founded in 1994, the brand is Narada. they even have the warehouse in USA. their prismatic LFP cells are with aluminum cases. 50Ah, 80Ah, 100Ah, 105Ah, 125Ah. their NMC cells is 42Ah. en.naradapower.com
This is cell inside narada 48v 80Ah
I dont know it is originally made by who
Usually narada use for telco back up power

White case, green terminal covers? The manufacturer name was in Chinese, and I sold them shortly after making that video unfortunately. I was never able to figure out who manufactured them to this day.

I bought them from a guy on craigslist, who bought them from a guy in Murrieta, CA. I tried googling the numbers on the cells and found nothing.
If you have something in Chinese that is difficult to be googled out, maybe i could help you guys.
 
Anybody ever buy from Dongguan 158 Technology on Alibaba?
 
@Dzl Do you have an recommendations for Canadian options? It would be fantastic to have a resource like you've created for the US-onshore options for your Northern neighbours (who are still struggling with Alibaba, etc.). Thanks!

I recently found Taranis Energy here in Canada and was impressed enough i ordered 8 230AH Eve cells for $1,898.00 to my door. The cells were delivered 2 weeks ago in good condition,after unpacking & voltage check i'm happy with them as they appear to be perfect & new.
 
Appreciate the response.

You’ve helped solve one mystery for me - I saw the EVE LF280 price on Alibaba and it was over $200. For low-volume sales I could understand - to discourage sales to end-users.

But the price for MOQ of 500 was also over $200 - 2.5 to 3x the price from these ‘Grey Market Sellers’ as you call them.

So yeah, if that’s truly the market price for new Grade-A 280Ah cells sold in full-palette+ volumes, these $70-80 cells must be excess stock, outdated stock (I see EVE launched the LF280N last December) or defective in some way...

In a situation like this, the reputation of the (grey-market) vendor is paramount, so I suppose I’ll monitor the board for a while to see a bit longer of a track record of happy customers (and hopefully no horror stories) before pulling the trigger.
$200 for one 280AH cell would translate to $3200 for a 16-cell, 48v nominal battery . That is not a good deal. You can buy a 48v, 100AH lithium golf cart battery for max $900. Multiply by 2.8 and you get $2520 for the same capacity. So to build your own battery with single cells, given the cost of intercell straps too, you need to be looking for sub $150 cells. That $70 grey market price is probably more than they actually cost in China.

I agree. I just ordered another 4x280AH as spares from where i have already bought 56 cells over the last 2 years or so and paid $570 that includes $90 in shipping.
 
@Will Prowse you used some white plastic prismatic cells in a video a while back. I've never seen cells like that before, do you recall the manufacturer?

I know it has been 4 years.. but are they these cells?


assuming this is the video

I guess they're "hipower" the main website that comes up seems like it is unrelated: https://hi-powerbatteries.com/


There's some guy who has a bunch too:
 
I would say ALL chinese suppliers deliver random quality at random times. Ones less frequently than others. Seems to be the only rule for me
 
This is the first time I've looked closely at this particular forum. Even though the Ah capacity of the EVE cells is very high, I am astounded that buyers would even consider paying $200 for a 3.2v cell. My inexperience is probable at fault here, and while I would really like to put a battery together at some point, I don't think I would ever pay that kind of price per cell, and I really cringe when I think about buying 15 of them...
