(6 reviews) Write a Review


Aspire 18650 Flat Top Battery (2-Pack). 

Amongst the very best in the industry, offering brilliant value and being ultra trustworthy they are a popular first-choice product within the modding community.

Offering powerful high-peformance and long life the 3.7V Aspire 18650 2500mAh high-drain ICR rechargeable battery provides a much longer run time than a standard ICR battery and is designed using Aspire's new Solid Solution technology engineered specifically for high discharge current (max. 20A) applications.

The science behind Solid Solution technology successfully blends the high-capacity characteristics of the colbalt based Li-Ion battery cell with the high safety profile of the manganese based Lithium Li-Mn 204 battery cell. These advancements make this the immediate and preferred choice for those who require high drain ICR18650 battery cells for use within a Personal Vaporiser (Electronic Cigarette), a flashlight, or for any other application that requires a high discharge current whilst also being equally suitable for applications that require a normal drain ICR 18650 battery.

    Aspire 18650 Flat top 2500ma

    Excellent Aspire batteries fast delivery Charged up and in use in 2 hrs. Seem to last a while with a Atlantis tank using 100vg cigar flavor After recent safety issues with fakes on ebay and amazon I decided to pay the bit extra from a proper online shop. Tbh the price is very good as these retail over ĺŁ30ish a pair.
