Official specifications:

  • Model: 26650P-3.7-5500
  • Color: Black
  • Cell Type: Lithium Ion
  • Head Type: Button Top
  • Mark Capacity: 5500mAh
  • Actual Capacity: 5300mAh
  • Voltage: 3.7V

  • Rechargeable Times: 1000
  • Built-in Protected Circuit: Yes

The two cells do not match perfectly (With 26650 it is difficult to get perfectly matched cells) but the capacity is fairly constant within rated load. The protection prevent drawing 7A for a long time.

























Conclusion

The cells are sligtly below rated capacity, but they are some of the top capacity 26650 cell and for single cell low current (up to 5A) usage, they work fine.

hmm, didn’t someone test these a while ago and got >5500 mah? not sure if that’s with less accurate equipment, or just some variations of different batteries/batches.
