Hello all,

I'd like to build a 12v Battery with 4x EVE 280K batteries. With the EVE factory two hole terminals. These seem to be the best value at the moment over the 304AH.

Which company has the best (or most consistent) storage grade cells with good shipping to Australia. Should I ask For V3 Cells?

Reading the other posts and watching (Andy - Off grid Garage, Will Prowse, Ray builds cool stuff) it seems these are the top 3 small lot battery companies.

LUYUAN

QSO

DOCAN

At the stage of sending them all queries but would like to know who the REAL contacts are in November 2023.

Also looking to build much bigger 48v packs in the future with a reliable supplier.

Cost: The cheapest seem to be no lower than 90 USD (138 AUD) per cell.

Any help would be appreciated. Hopefully this thread will also help others.
 
I've been in communication with the EVE factory, and was told they ship with either flat terminals or welded two hole terminals. They recommend the latter for non EV applications as they can ensure the quality of the welded terminal. It is possible they send it off to get welded, but the QC is meant to be done by EVE. Please advise if you have heard any different.
 
From your list, I would buy only from Luyuan - consistently a good supplier.
Expect a delay on top of their claimed timings (+15 days in my case).
Would buy again (battery box in my case), but would also buy cells.

Search for Docan here in the forum... yes..., YouTubers have more luck than regular people ...

And read the spec sheets for that cells!!
 
Amy Wan, is the Owner of Luyuan and buys only directly from manufacturers and provides factory test reports.
In order to get a proper quote, you do have to pen a Chat/Messenger session as the S&H costs posted and "guesstimates" only and on the high side.

Many are not aware, but they also sell a lot of pre-assembled fully tested packs, some are surprised (pleasantly) when they ask.

<--- just a wee bit of assembly happening.
;-)

Purchasing Tip to Save CASH !
If you get all components from 1 Vendor ie BMS, Extra Wires and the "bits" they can package it all together. Every box has a Min cost, + weight etc, it adds up terribly fast. By bundling everything up means less packaging (- per box fees etc) and does save some bucks.
 
Thanks to all who have replied so far ?

I will talk with Amy Wan of Shenzhen Luyuan. I don't have the time to mess around too much with suppliers.

This is the start of the OFF GRID LIVING journey! Cheers ?
 
I have been delighted in purchasing from both Amy Wan (Luyuan) and from Amy Zheng (Docan). Other companies, not so much.

In requesting a price from Docan, as well as Lyan, it is generally better to contact either of these persons directly (rather than purchase through the website). Better pricing and more responsive service. Amy Zheng (Docan) is best reached via FaceBook messaging.

I wasn't aware Amy Wan of Schenzen Luyuan had a direct contact method. Can you please share?

You need to open a Chat/Messenger session on Alibaba with Amy Wan of Luyuan to get into direct contact. A Messenger session is better actually.

Go to https://szluyuan.en.alibaba.com/
Then scroll to the bottom and you will see this below, select Contact Supplier and that will create a Messenger Session.
TIP, Keep the language straight & simple (no slang etc) ask direct questions and allow time for a response, she can read english fairly well now but still needs to translate at times & slang / colloquialisms don;t work well.

Hope it helps, Good Luck.,
 
I got a delivery from 104 batteries from Amy Zheng(Docan)and some other stuff and very happy with it,it arrived a few weeks ago
everything was in a wooden case and filled up so that nothing could happen,not even a scratch on the carton boxes
they look excellent,nothing wrong with it,perfect and Amy is easy to contact and fast answer and what she say it’s happen and true
 
Maybe i am wrong,if you chat people there’s must always some trust if you talk about this amount,and for me its more than okay with this shipment….this is my experience with Amy and Docan( Amy on first place?)and this EVE batteries

I’ve done one previous order with Amy, very pleased with my original order. Pleased so much in fact, I’ve got 20 more cells that should be arriving tomorrow (Tuesday). I can post pictures and impressions of the shipment when it arrives.

https://lifepo4.com.au/electronics-store-cart/ I just found this .
 
why not buy directly from eve factory ? i think they are on alibaba as well

You can, I hope they improved shipping since last time someone did that:

If you want a container full, they're the way to go. Small orders, not so much - unless things have improved.
 
Also there prices are a lie, wait to you get the final price add 50% to whatever they list it for once you get the bill for shipping and all other jambalaya of fees they throw in.
 
Update:

I ordered from Amy Wan of Shenzhen Luyuan.

$116 USD per cell
$90 USD Shipping

With flexible busbars, bolts, cell separators.

Seems to be good value.

Happy so far.


Ordering from EVE is only a good option if you want a pallet of 40+

They directed me to a corporate forwarder for smaller shipments in the US, but this seemed too risky.

At least with Alibaba the transaction stays on the platform.
 
Just placed an order for 16 EVE 280ah from Jenny Wu from Docan $85 each see how it turns out coming from China. Hopefully good seen mixed reviews. She had REPT for $65 each but she said no testing datasheets said the EVE were better I went with those. She sent me these pictures.

She sent me this screen shot. I also ordered a JK B2A24S20P BMS for $165. She said I have 15 days to contact them after receiving for any damage. If there was other issues they would handle it. I was trying to get her to give me some written warranty I could take it to my credit card company if needed for a charge back. Ill save all communications she stated these were tested and new grade A.

Dang! That's perfect what did you say the price was?
As long as your cells that match that test report you should be getting decent cells.

I have been more than happy with the products purchased from Amy Wan. Arrived earlier than expected. Arrived in excellent condition. Support has been amazing!

$85 each x 16 $165 for the BMS totaled out with shipping to AZ and fees was $1742. If I remove the BMS and take the total divide by 16 about $98 per battery shipped. US companies are all out of stock it would be another $400 with taxes and shipping if I bought from them, I'm risking about $1200 on this. I'm hoping that my credit card will bail me out if it turns out to be a scam.

Trying to figure out a way to test these I have a good multi-chemistry charger made by Revolectrix from my RC airplanes it only goes up to 2000 watts. It has a cycle feature I don't think the discharge can go more then 20 amps rate at most. It does show internal resistance and I can get capacity reports.

That is good as long as you have matching qr codes, for extra safety peel back the black cover and make sure. I just hope they don't do the bs they did earlier where 1 person got grade A and the other got Grade B all depending on what type of buyer it was.
 
I just got a price Of A$270 per cell for grade A here in Australia. Wondering if the price on the next batch the shop buys will go down? I am willing to pay a bit more to avoid the hassle of dealing with China. (I got burned once already.) But US $ 100 = A$ 152. Big difference

How the hell are are you going to buy a chinese made product without dealing with china in some way?
 
Indirectly. Through a supply chain of people who are equipped to deal with china.
Call it what you will... I cant see how the dealings through all the middle men can be anywhere near as efficient or fair?... Your still dealing with china.

Negotiating power. The weak link for accountability is the international transaction. As a buyer of 16 or 32 cells the china dealer doesn't lose much by telling you to get stuffed, unless they really are trying to build a brand reputation to maintain. They are not on the whole notorious for maintaining this reputation.

An importer though may have a relationship of ongoing business, and therefore a lot more pull with the china dealer to motivate the china dealer to send good cells.

So how many agreed on reputable venues are their through these channels?

The 5 Pillars of being a reputable supplier:

1) Must have manufacture test reports for each individual cells, and absolutely not have cells with sanded off counterfeit qr codes that have been re-lasered.
2) North American phone number & physical North American address
3) Reasonable customer support and should respond to emails or phone calls within 24-48 hours
4) They have been in business for a year or more
5) Fair prices, no they will not be as cheap as direct from China, but are reasonable considering you are getting items faster and have actual recourse vs Alibaba where there is NO recourse only credit card dispute.

You put all 5 together and you have yourself a reputable supplier. Unlike Alibaba where when they are caught, they can just start a new company and be back to start scamming in no time.

Seen that happen on Amazon & Ebay as well...
Reality Check: There are Scammers EVERYWHERE and more "schemes" to liberate people from their money than any of us can count regardless of what continent or nation you are in.

Pillar 6)
Dealing with a company (regardless of location) that has repeatedly delivered exactly what was promised with a good track record with numerous clients. You know, the "Known Good Vendors" with a good history.
