Samsung 25R R5 // 18650 2500mAh 20A


This product is unavailable

The green Samsung 25R R5 supersedes the previous blue 25R R2 that was extremely popular with vapers in New Zealand and worldwide in 2015. The electrolyte balance was tweaked giving this cell an excellent upgrade. Samsung has said the 25R5 does not have improved performance over the 25R2 but has a longer cycle life of more than 250 charge cycles.

Mooch has given the Samsung 25R R5 a maximum vaping amps (MVA) rating of 25A. You can pulse batteries above this but it is advisable to stay within the MVA, or inline with the maximum continuous discharge rating for a safety margin in case of a device malfunction.
