Two options:

- Sort by orders. If seller has sold the most, probably a reliable seller.

- Buy a handful (or samples) first (you can ask seller that you need samples first), and test their capacity (using e.g., a good charger, I have Zanflare C4). The model I mentioned should have 3Ah (or 3000Ah). If confirmed, those are legit cells.

Plus the first order is the least likely to contain bad cells because you’re doing QA.

Correction: 3Ah or 3000mAh.
