Efest IMR26500 3000mAh (Blue)



Official specifications:

  • High Drain Protection !!!
  • Spec: IMR-26500 3000mAh 3.7V
  • Positive Top: Flat top.
  • Color: Blue.
  • Material: LiMn

This battery is a short battery, i.e. it is only 50 mm long, compared to the usual 65 mm long, compared to the longer types, this battery has a good capacity.










The battery is not good at high current, it works best at 3A and below.















Conclusion

The capacity of this battery is good for a 26500 battery, but it is missing the usual IMR high current capabilities.
Generally the performance of this battery is close to a 3100mAh 18650 battery, except it is worse at high current. This makes the battery best for short designs with a single battery and not much more than 3A current draw.
