Samsung INR18650-20Q 2000mAh (green)



Official specifications:

  • Battery Capacity (Mfg Rated): 2000 mAh
  • Battery Chemistry: LI-Ion
  • Battery Feature: Rechargeable
  • Battery Form Factor: 18650
  • Battery Maximum Voltage: 4.2 V
  • Battery Minimum Voltage: 2.5 V

  • Current Output: 15 A

Thse are high power batteries for use in tools.










The cells can deliver 20A with full capacity and the maximum difference in capacity is about 0.6%.
The voltage at the lower currents is not very impressive, but in the 10A to 20A range it can match IMR cells, but with greater capacity.















Conclusion

This is a very good battery, but there is no reason to use it, except if you need a lot of current.
The R version of the battery is slightly better.
