Vappower IMR18650 2500mAh (Green)



Official specifications:

• Battery Capacity (Mfg Rated): 2500 mAh
• Battery Chemistry: Li-Ion
• Battery Maximum Voltage: 4.25 V
• Battery Minimum Voltage: 2.5 V
• Battery Rated Voltage: 3.6 V

A very high current 18650 according to the rating (35A continuous, 50A puls).











The 35A rating is optimistic, but it can do 20A. I would have like a bit better tracking at high current.















Conclusion

The battery is acceptable for a high current cell, but as is often the case the specifications are too optimistic.
