The Samsung 25R
is an all rounder and certainly one of the most trustworthy and balanced 18650s on the market. This authentic, grade A-1 flat-top 18650 battery features a 2500mAh capacity, 20A max continuous discharge rate, and a longer life cycle than previous Samsung 25Rs, and is an ideal choice for standard, variable wattage and temperature control devices!
Samsung has slightly redesigned the chemistry for the 25R to increase its overall life cycle. The change in the colour of the wrapper from blue to green denotes the change in chemistry.
