Evva 18650 3400mAh (Black)
- 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.
Evva has take a very good cell and added a good protection circuit and button top.
The result is (as expected) very good.
