Sanben Battery store AliExpress

SANBEN ist the same as PWOD. I had some discussion with SANBEN about battery specs and got an e-mail sent by "Iris from PWOD official store". So this should evidence enough, SANBEN and PWOD are the same store. Seems they forget to switch the sender name in outlook ;-)
 
SANBEN is selling batteries with wrong QR code position (CATL 310) and batteries with correct QR code. Seems this is a big gamble to order there. Lead time is around 2 months....
 
I placed an order for 320 aH cells in June 2021. Received in the same good packaging as the rest of the sellers I’ve purchased from after about 9 weeks. They have welded studs. 62% were swollen about 1/8”. Capacity tested at 306-314 aH. That’s not acceptable to me. They should be advertised as 300 aH. I sent them a message. Trust me, they are lying about their battery quality and will do nothing to make it right. Steer way clear!!

It's important to compress these cells. They will bload up immediately, if they're charged without. Will said in one of his last videos, that's because of the thin casing because they're designed to use in automotive applications, where they are fixed in a frame.

62% from Sanben were bloated right out the package and tested at 306-314 aH out of 320.

I ordered from Sanben, 8 x 280 Ahr cells. Received in good condition. Not swelled at all. Perfectly flat. Seemed to measure as matched. Did a top balance which went very quickly. Load tested to 282 AHrs when configured as an 8S pack with cell cutoff at 2.7 volts. Happy with that order.

This is the QR code on one of the cells. They all had the same date code.

I have recently placed a second order, am a bit nervous, but hopeful. I think we just never know.

As a note, this the 'same' set of batteries is now $1300 from them, not the $1223 shown above. That was the price in June.

Don't know if you are the same person or not, but that is the second QR I have seen for March, 2021 LF280s. Some suppliers are selling slightly older ones, i.e. made in 12/20. Mine were 12/20 production but the three I tested so farhad 286, 287, and 288 amps.

I've heard this automotive use a few times, but try as I might I cannot find an EV manufacturer that uses thin wall prismatic LiFePo4 cells. I'm sure if they did there would be plenty of used cells available from dismantled cars, just like the Nissan Leaf cells.
Check out David Poz's videos where he dismantles BMW, Volvo, and Chevy battery packs. Not a thin wall prismatic cell in any of them.
And how would you cool prismatic cells if they were clamped together in an EV?
 
Sanben said,”Swelling is normal”. Interesting that 62% of the batteries received were swollen 1/8-3/16” and the others were flat. Cap tested 306-314 aH out of 320 aH. Voltages all over the place, IR= .24-.25 (Max per spec). I can guarantee you, I will not buy anymore from Sanben or recommend them. Only from Amy or Hayley.

I received SLT/Amy’s 280 aH batteries and they were all flat or slightly concave, voltages within .001 of each other, IR= .18-.19 mOhms. Great condition. Capacity tested at 284 out of 280 aH, 25A discharge from 3.65-2.50V. Wonderful.

For sake of options, Basen ships the same batteries as Amy. My set of eight EVE LF280 were all in perfect physical shape, all were IR=.17, and capacity tested 286-288 (out of 5 tested so far). It was cheaper to get my EVEs from Basen in the US with one week delivery than waiting for cells from China. Glad I found Basen as I am thrilled with what I got and the service, not to mention having them in a week :)
 
Lest anyone doubt SANBEN are OYE, or otherwise are any better...

China made teslas utilize LiFePo and soon US entry level models will all LiFePo, from BYD and CATL.

There’s a few videos on YouTube for the prismatic model 3 ~55kwhr pack.
 
Late to the thread, but I purchased a set of 4 320Ah, 3.2v EVE cells from this retailer. It took about 70 of the allotted 75 days before an automatic refund kicked in. They came well balanced, ever so slightly bulged, and tested at just shy of 318Ah on average.

At the time they were significantly cheaper than the other sources with high sales volume, but now are on par. They also don't have the studs welded anymore.
