Test/review of Nitecore IMR18650 3100mAh (Yellow) 2018

Nitecore IMR18650 3100mAh (Yellow) 2018







Official specifications:

  • Capacity: 3100mAh

  • Voltage: 3.7V

  • Chemistry: IMR

  • Recharge: up to 500 cycles

  • Max pulse discharge: 35A

  • Max continuous discharge: 20A



This is a high current and high capacity cell from Nitecore in the usual 18650 size.











The discharge curves tracks nicely, but the cell get rather hot at 20A, I stopped the discharge. The B cell helped with that, the internal protection tripped and I could not do any more tests.





















Conclusion

The cell is good, it can deliver 15A continuous and a lot more for a shorter time.
