Best Chinese li-ion pack supplier?

[MaximusAnonus]

Hi,
anyone got any tips on a good and tried Alibaba suplier who can supply about 100pcs of 1S3P 18500 li-ion packs from grade A cells?

You will have better luck if you get the terminology more precise. 18650 is a common cell form factor. What is 18000?
Li-ion could mean any one of many different Chemistries of cells containing Lithium. What Watthour capacity are you needing? What is 1S3P? A battery made from three 100Watthour cells could carry the same energy as a single 300 Watthour cell.

18500 is an extremely common size. So are lithium-ion batteries. Capacity? The highest one. Obviously. Panasonic makes nice 2040mAh cells. No idea what the Chinese are making. That's why I'm asking. 1S3P is obviously 3 cells in parallel. Or do you prefer 3P1S?

• Lithium Manganese Oxide. ...
• Lithium Iron Phosphate (LFP) ...
• Lithium Nickel Manganese Cobalt Oxide (NMC) ...
• Lithium Nickel Cobalt Aluminum Oxide. ...
• Lithium Titanate. ...

As far as I know there are at least three nominal voltages among those chemistries.

Amy Zuang she is in this forum. I bought 16 280ah EVE cells they shipped from Houston warehouse at chinnese prices. Got them in 2 weeks

Yes I bought from her some 240Ah cells too and she is really awesome but she doesn't do small cells unfortunately.
