the site alibaba sets kinda tuff standards for their sellers. they have to send a photo ID and use their government issued ID. if they get too many bad raps alibaba will suspend their account. they will lock their money. so the odds on being cheated is limited by alibaba. to some extent. also the odds of them switching names and using a different company is really hard for them. still beware
It's easy to get "employee" who uses their ID and name for new account.
Trade assurance is great, if you don't receive, receive clearly damaged or missing parts
Cells that look good but give 250 Ah when you bought 280Ah...
That is a battle you don't want.
Seller can ask of all crazy tests that will eat up many hours to discourage.
Strangely, trade assurance normally accepts those absurd requests.
And even if you live through them all, you still receive partly or no refunds.
If you do need to get the help of trade assurance, and the proof that would be enough for normal Western standards is not good enough, don't bother.
Just go to your credit card company and ask them to get FULL refund without all the crazy hassle.
Visa normally is quite assertive.
Depending on your own history ;-)
Timing and product different from Western ideas.
I like to compare with your microwave hamburger or hotdogs or lasagne.
They never look even close to the pictures, but if it isn't too bad, you buy again for price and convenience.
Quality is normally not that bad, especially for our purposes, solar, where 0.2C is already high.
If you would use the same cell for your EV....
You are in trouble.
