Hello all,
I am new here and was just looking for some new Rack Batteries on AliExpress.
The Store #1540706536 has a Sales going on (HU activity or something) and are offering these Rack Batteries 48V/200Ah for 70% off the original price right now until Nov. 11th 2022 for an unbelievable price of $660 per unit !!! The unit ways 85kg, and its supposingly a CERRNNS brand.

Here is a screenshot of the offer they have going atm:

I have to experience whatsoever, so hoping for someone to give me a hint, if this is possible and trustworthy or not.

Thanks for any help on this issue.

Here's the link. Free shipping also...


I'll bite. I'm retired and have plenty of time to chase a refund with my cc company and/or Aliexpress if it's not legit. It'll be interesting to see what's really inside once it gets here in Jan 2023...

Were you in contact with a salesguy? I was, and he told me if I buy 4 units, I would even get a rack with them. But on the other hand, he also stated that there was no manual coming with the units and when I asked about someone, that could provide some technical info about the product, like how to set the dip switches etc., he told me that he is only a salesguy and has no clue and that he can't provide me any contact for a technician. So, still don't know what to think about it. I am also retired and have enough time to chase a refund, but just not sure if its worth the hassle in the first place.

Whats also interesting, the 100ah unit is $600 and the 200ah unit only $60 more. :) ???

No sales guy. Im rolling the dice, but It's worth the hassle, If these are legit and even if the 100ah units are what show up!

These look just like pace BMS units to me. A variation of this which I have 4 of already working with solar assistant:

PowerUp by ESS LiFePO4 48V 5.1kWh battery-5yr Warranty Rack/Floor Mount -Clearance – Watts247 Wholesale

watts247.com watts247.com

Very easy to set up. Yeah, the $60 difference is curious. I just got a shipped notice. We'll see what shows up.
 
Something is up because this one is $420
Battery

And Both Have Free Shipping From China !!!!
 
Most stores in Aliexpress with the generic names such as "Storexxxxx" are probably scammers. Although I did find some small electronics that actually arrived, buying Lifepo4 has proved to many of us that these stores are mostly scam.
Beware... I would pay with PayPal, so that you have multiple layers of protection (Aliexpress dispute, PayPal and CC company).

Yup. Exactly what I did.
 
At that price including shipping, I will be surprised if more than a tracking number shows up.
Plenty of examples of cases with chunks of tile inside for weight…
Fingers crossed for you though.
 
Compare it to the official CERRNNS Store (looks like they just forgot the "2" infront of the $660 on the other store ;)

never trust computer generated images without actual photos of the product.

Hi there, this is Holly from CERRNSS factory, while I'm in charge of Alibaba not AliExpress. Just want to mention that the costs of cells are quite clear on the market, if the price of battery pack is very low, it probably would be a scam. Never covet little advantages

Warning. CERRNSS (via AliExpress) shipped me a damaged battery. Sent them pictures within 1 hour of receiving the battery. Told them send me a shipping label and I will return it for a refund. CERRNSS, said OK. Weeks went by no shipping label no refund. Started protest with PayPal. CERRNSS objected to the protest. Still ongoing with PayPal to get a refund. Warning

This feels so close. I got scammed by CERRNSS via AliExpress. I'm sorry about that, but you probably lost your money AND your battery.

Cerrnss protested with PayPal, it went back and forth. The last was I pay for return shipping to China and I would get a refund. I refused. Not sure what is going to happen with that cycle. I did open a dispute with my CC company.

I sent an email directly to Cerrnss, crickets.

Funny, AliExpress has in the buyer protection statement "...arrived damaged..." gets a refund.
PayPal has the same.

The thing is, there are three CERRNSS representatives in this forum, and all of them don't give a damn about us.

Am I right, @Zack Lin or @Subella Li?

I can guarantee that this store is fake, but since you have purchased it, you can take a video and leave evidence as soon as you receive the package, in case you need to make a claim for the product.

From my experience with CERRNSS, a claim will be denied. Regardless of any facts.
 
Normally the battery price should be around 1rmb/wh. for EXW price. EXW price means not shipping cost and other fees included. This is how I would calculate a battery price. eg. 48V 100Ah price would be 51.2*100*1rmb/wh equals to 5120rmb. Then will quote 720USD. The reason for multiply 51.2 is, 48V LFP battery usually made by 16 battery in series, which is 3.2*16=51.2V
 
The battery price listed in AliExpress is about 0.45rmb/Wh. You shouldn't expect something good from this price. It's only half of the normall price. They're either using second hand cells or making a mistake and waiting you to cancel the order. Using Paypal for the payment is smart
