Innovative
Highest capacity available
These second generation 18650 cells offer the highest available energy storage capacity, especially under heavy loading condition. During discharge, our 18650 3100mah maintains high voltage and high capacity output for better product performance.
Only 68mm in height
We are the first to offer 3100mAh 18650 li-ion with only 68mm in height. That makes it highly compatible with all 18650 based flashlights in the market.
Button top design
The protruded button top design makes it work with any flashlight that incorporates hardware anti-reversed battery polarity protection. It also ensure conductivity when multiple batteries are used in serial.

World best and most reliable battery cells
These imported Japanese li-ion cells offer world-highest capacity. Each cell is fully tested and internal resistance balanced and sorted from the manufacturer (we also perform individual testing before and after packing, and before shipping out.)
Our 3100mAh+ battery cells outperform other Japanese and Korean leading battery manufacturers in terms of capacity, under-load voltage, consistency, and compatibility.
High capacity
Unlike other competitors, our 3100mAh+ cells give the highest capacitor, especially during heavy current loading. It is tested to yield 3100mAh at 0.2C of constant current discharge (see our own discharge testing below).
High voltage
High voltage underload is always preferred especially in single battery flashlight application for constant regulated output (check out our 2400mAh+ 18650 for even higher voltage underload).
High consistency
All cells are capacity and internal resistance balanced and sorted to ensure highly consistency within a production and shipping batch. This becomes important when multiple batteries are used in serial or parrallel.
