Samsung 25R 18650 2500mAh 20A Battery
The Samsung INR18650-25R is one of the classic high-drain 18650 cells: moderate capacity, strong discharge current, predictable pack behavior, and broad compatibility with 18650-oriented systems. It is best used where current delivery matters more than maximum runtime per cell.
For engineering calculations, use 2500mAh standard discharge capacity, 2450mAh rated discharge capacity at 10A, 3.6V nominal voltage, and 20A maximum continuous discharge.
Design note: the simplified charts below are presentation-oriented visuals based on the published product specification and product listing. They are useful for shopper education and pack-planning, but not a substitute for validating the finished battery system under real current, temperature, and enclosure conditions.
