Test/review of Hohm 21700 Run 3023mAh (Black-white)

Hohm 21700 Run 3023mAh (Black-white)

Official specifications:

  • Capacity: 3023mAh

  • Max Charge Rate: 5.29A

  • Continuous Discharge Rate: 39.1A

  • Max @ 80oC | 3.2V cut-off: 49.5A

  • Pulse | Peak: 56.4A (<=5 SEC ON >=30 SEC OFF)

  • Cycle Life Retention: 500 Cycles (73), 1000 (64)

  • Chemistry Type: QSP Li-NMC

This is a low capacity and very high current 21700 cell.

The two cell do nearly match and can deliver at least 30A with a minor capacity loss.


The batteries can deliver a lot of current, but capacity is in the low end for 21700 cells. I.e. these cells are mostly interesting if there is a need for very high current.

Thanks again for these reviews…

“Diameter: 11.5mm” is likely a typo.

That do sound a bit on the thin side.
Thanks, I have fixed it.
