NOW how do you have the same cell that Ezealco also happens to be selling in the usa? Or is this so new scam where they 1 set of legit cells in the usa and then use the same set of QR codes on a set of counterfit cells in China double dipping from there own stash.

UGH, you know F this, I'm done with Ezeal too, even though they are selling legit cells they are in bed with all these Bozos in China and they have Docan rubbed all over...

I was actually just wondering a bit a go if the cell would show up in the Ezealco reports, being only 12 days apart. I feel like the Ezealco reports are probably a larger range than the quantity that Ezeal is actually reselling in the US.

But then I was also suspicious that a cell 12 days off mine is now shipping from China. The good explanation is August had some reason for a big cell auction onto the grey market. The bad explanation is someone is reusing data.

I can't tell you gotta peel them off they have gotten soo good and creating fake qr codes I think they are not actually machining the entire top surface of the cell to put fake qr codes on them.

But not giving you a test report is a huge red flag!

forget about returning them, the post office more likely to throw u in the pokey then to let you send them back to China.

That it's why I was so worry, because no documents was provided and the part that this company is a partner company for Ducan or something like that.
This were shipped from California, so I guess that's were this need to go.

 

[Anthony0488]

the eve report you can email to:

Meteor.Ye@evebattery.com

or go to evebattery.com and ask them please verify if this is real.

It takes 1-2 days, I verfied reports form ezeal, batteryhookup, sunfunkits, luyuan and eel said these are all legit. The only ones they did not respond to were from eel battery which look suspiciously altered, however, they did not say the eel reports were fake. May be this is a Chinese thing where they prefer not to accuse. It was enough for me not to trust eel, even though have there v3 case which is pretty decent.


So yeah if you make a fake report you are just creating more evidence in my book.

Will do, thanks a lot for your help.

If they're shipped from CA that makes even more sense. One middle man brought a batch over to Long Beach, and they're both still selling it. Maybe California buyer, Ezeal, and Docan are all related, or the same, or just business partners.

But this were ship from a warehouse in the USA

If they really shipped from California and Ezeal is still shipping only from Texas then I gotta go to Docan next time. No reason for my cells to travel further away before they get me.

Was your packaging identical to mine?

All my batteries are on 2 on ezealco documents. The representative even tell me that they have nothing to do with Docan and that they have separate distribution center in the USA, plus that Ducan was run by her boss wife.

That can be the reason, but if that's the case been at front and telling the truth with the documents to prove it, will be a less headaches for everyone. Forgot were I read that Docan was selling using other companies, because all the bad reviews that their getting or something like that.

 

[hwy17]

I'm getting less suspicious now, not more. It's perfectly plausible that his August 23 304's batch came from Eve together, got their studs welded at the same place, got the same ready-to-ship 2/box parcel packaging treatment in China, got loaded onto containers to Long Beach, and they're still selling stock out of this big shipment.

Maybe they're partners, maybe they're all loosely compartmentalized business ventures of one battery billionaire who's smoking cigarettes at a craps table in Vegas with a box of black chips in front of him, as he spends his Friday nights more often than not.

Well if they were all honest they'd have to tell us all why our cells weren't good enough to go to their big buyers in the first place.

The company that sold me the units to me, charge me $96,00 shipped each and Ezealco has it for $106, I guess there is another company that sells then to this 2

Good deal, I paid $124 shipped in November. I think they're good cells. Very well balanced out of the box when I started them up in maybe February or something. I believe I get full capacity out of them.

My BMS has it's own logic for reading internal resistance by the voltage drop under load and I have two cells that are still reporting a little high, but this reading is easily affected by the bus bars and cell tap connections. I had various cells that were reading much worse before, and all I did was tighten the nuts more to fix the out of whack ones, so I'm really not sure if the last stubborn difference are really in the cells or just a connection quality issue. I'm probably not gonna chase it down much further like try to move them around and see if the bad reading moves with them. Just gonna run it.

This is such a clown show they could just cut the crap and sell under 1 company.

What BMS are you using?

 

[wpns]

There seems to be some confusion as to whether we want Grade A EVE cells with traceable provenance, or we want paperwork that says the same thing but at a lower price (or a higher markup for some middleman).
The middlemen don’t care, they’ll sell you what looks like what you want. If it’s non-functional when you get it a couple of months later they’ll disappear and form a new company to do the same thing. At least it’s profitable. We’re the ones driving this behavior by not buying Grade A cells directly from EVE or CATL or …
A doctor friend tells me it’s the same thing in drug manufacturing, India will undercut everyone’s prices because there’s no active ingredient.

 

[hwy17]

Orion. If you've been looking for a BMS that will prolong the joy of the DIY build process into tens or hundreds of hours, and repeatedly demand another couple hundred bucks from you for necessary accessory parts, then I really recommend it. It's the best.

hwy17's Orion battery build

Rather than keep spamming new threads out as thoughts come up I'm starting a build thread now to share as I go. 16x EVE 304 from Ezeal Orion JR2 BMS Planning work in progress (polarity not detailed yet):

diysolarforum.com

 

[Ampster]

Orion. If you've been looking for a BMS that will prolong the joy of the DIY build process......

I used Orion BMSs since 2015 until last month, when I converted from a DIY pack to some Pytes rack mount batteries. I had Grade B cells in a 3P16S configuration and they needed more balancing current than the Orion could provide so I disabled the balancing on the Orion and used a 1 Amp JK active balancer. The Orion JR2 communicated easily with my SolArk and the SOC measurements were very accurate. It used a Hall sensor for current measurements.

You should know I've been around enough to know that! Lol, jk. You had some level of familiarity with the DIY EV scene before I believe? I think we still have a lot to learn from them. I'd love to get a strongly opinionated one of those builders in here tearing people a new one for some of the common practices in DIY solar batteries lol.

I was planning to do my second pack with another one of he high effort BMS platforms but my desire to go through that design effort again is waning, it consumed me for several months and was eating my work and personal time. I mean it did that because I enjoyed it, but still.

So I might actually end up like you did, placing another order and paralleling them into my existing cells. I have a 2x8 case and I'd put the second set in another case which would be fun that it would really show off the pack splitting capability.

For now, I'm pursuing an attempt to see if the Orion really can balance a 300Ah bank without a handicap. It's cycling 50-90% on average each day and I'll see if maybe biweekly 2-6 hour full balancing charges with supplemental power is workable. Updates on that going in my 55v charging method thread.

 

[Ampster]

You should know I've been around enough to know that! Lol

I was posting it for the benefit of @Anthony0488 . I am a fan of parallel cells but as I mentioned my Grade B cells did not stay balanced with the Orion meager balancing current without significantly reducing voltage and thus capacity. Even then I only charged to 3.45 volts per cell. My pack was purchased over a years time and they came from three different vendors so they were not even close to being matched. I do have a Neey active balance that has never been used if you or someone else is inerested. I have been meaning to put it and my used Orion JR2 BMS up on Marketplace.

I did contact the EVE company direct and they quote me the batteries at a good price, but couldn't ship them self at that time, so I have to look for company that does it and tosay I received a E-mail that they will be willing to ship it, for $650.00, when I get the money back, I ordering straight from EVE.
