Lol
You really are a newbie...
Slightly overrated is OK to lie about the real capacity??
As long as you sell cheap?
I hope you open a store soon...
You'll find that your customers and government think differently.
That's illigal business. Scam, foul play, dubious, not correct.
If something doesn't work, refunds are easy at AliExpress.
If someting works for 80% you won't get a 20% or even full refund.
Many times it's useless for the purpose you need it for.
Send back for free??
Joker. Really a newbie.
How often did you send back postage paid to China and got your refund??
With over 2500 different orders on AliExpress for the last 5 years, I've seen most of the tricks.
For USA: "Never trust a car salesman"
The rest of the world: never thrust online offer.
If it's too good to be true, it probably is.
Your acceptance that you are getting scammed does not make it OK (or normal!.)
Please look at your USA postage regulations of private persons sending lithium battery.
You can't. Special line for professional sellers only who need to follow tons of regulations.
Chinese sellers talk sweet to make the sale.
If you really are able to send one back for free, (pics and videos for proof) I'll buy 4 new for you (=$200).
I put my reputation in this.
@Will Prowse , you can block me if I don't live up to this.
FYI, my cells (total 37.5 kWh) are on Average $108 per KWH.
That you didn't lean yet on how to make a good deal on the more complex Alibaba.....
Don't blame other for this.
