LG 20650 HG6 3000mAh (Blue)







Official specifications:

  • Max. continuous discharge current: 30A

  • Nominal capacity: 3000 mAh

  • Nominal voltage: 3.6 V

  • Discharge end voltage: 2.0 V

  • Charging voltage: 4.20 +/- 0.05 V (Some say 4.35V)

  • Standard charging current: 1500 mA



This is a high current cell with slightly larger diameter than 18650 cells.










The discharge curves tracks nicely, but I do not get rated capacity, it may be because I do not discharge to 2V or it might be because the batteries must be charger to 4.35V for full capacity.















Conclusion

This is the smallest of the newer larger cells and it do well for its side.



Notes and links

Vapcell told me that I was missing some cells in my comparator and they would be happy to supply them.

Temperature graphs missing. The 30A discharge curve was 75°C cut-off for one of the cells, that says something. With regards to the capacity rating, 2.75Ah class imho.

Thanks for another nice review.

Cheers :-)
