Top binned CREE XP-G S2 LED

Ultra high capacity Japanese cells. Protruded button top design.
Measures only 68mm in height!


Ultra-high capacity

These second generation 18650 cells offer ultra-high capacity at 3100mAh.

Only 68mm in height

We are the first to offer protected 3100mAh 18650 li-ion with only 68mm in height. That makes it highly compatible with all 18650 flashlights and chargers in the market.

Button top design

The protruded button top design makes it work with any flashlight that uses hardware anti-reversed battery polarity protection. It also ensure good conductivity when multiple batteries are used in series.

  • 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 platform

    The ET 3100mAh 18650 offers high voltage output even under heavy loading. This offers longer constant regulated output runtime in a single cell application (buck circuit type).

    High consistency

    ET 3100mA raw cells discharged at 2A (yields 3001mah) and 4A (2904mah) respectively. When discharged at 620mA, it yields full 3100mAh capacity.
