Evva 18650 3400mAh (Black)



Official specifications:

  • Min Capacity: 3250mAh
  • Typical Capacity: 3400mAh
  • Voltage: 3.6V
  • Quality Lithium Ion rechargeable cell (Used Panasonic NCR18650B cell )
  • In Built Safety Circuitry, IC used Seiko of Japan chip.




Evva has a series of protected high capacity cells for flashlight (and other) usage, this is the 3400mAh version.










The discharge curves looks just about perfect and with the overload protection tripping with a continous 7A load, it also looks good.















Conclusion

Evva has take a very good cell and added a good protection circuit and button top.
The result is (as expected) very good.

I run these (button top) in my BC 30 they work great, although flat tops would be better. They are a little tricky to remove
