EnerPower+ 18650 2250mAh (Blue)



Official specifications:

  • Nominal Voltage: 3.6V
  • Capacity: 2250mAh
  • Minimum Capacity: 2150mAh
  • Standard charging current: 450 mA for 5.5 hours to 4.2 V / 0.2 C
  • Maximum charge current 0.5 C/1200 mA
  • Protection: 7A
  • Deep discharge protection: at 3V
  • Nickel base plate for added durability
  • Diameter: 18.5 mm + / - 0.01
  • Length: 67.8 mm + / - 0.01
  • Weight: 46g




This is a high current battery with protection.












The battery has no problem delivering 7A, but the protection does reduce the output voltage, compared to unprotected batteries.















Conclusion

Adding protection to the cell, makes it easier and safer to use it, but performance is lower than unprotected cells.
The battery is a very good battery.

Thanks for the review. These are the first of the CGR18650CH that I've seen with protection circuit.

Do you have any data regarding low-voltage cutoff ? Thanks.

No, but it is probably between 2 and 2.5 volt.

Thanks so much! Frontpage’d and Sticky’d.
