"What is the difference between the blue and green Samsung 25R 18650?

Samsung SDI guarantees that the performance of the 25R2 with blue PVC and 25R5 with green PVC are totally same.

The percentage of Electrolyte is change than 25R5

FEC: 3 -> 5%
SN: 1.5 -> 1%
PA77: 1-> 1.5%

The life cycle would be better than 25R5

Bottom-line: The green 25R5 has a better cycle life.

A cycle is one full charge and discharge of the battery. If someone asked you how old a battery is, you should answer by telling its cycle count. So what is the cycle life the 25R? A quick check of the spec sheet yields the answer:

The 25R2's life is: 250 cycles. This is tested at 20A, the cell's max. continuous discharge rating.

After 250 cycles the maximum capacity the 25R2 can hold dips to 1500mAh or lower (this is at 60% of its starting capacity, at 25℃).

So we can say that the 25R5 has a cycle life greater than 250 under these same conditions."

With a 20 amp max continuous discharge this battery can handle sub-ohm builds down to .22 ohms (at your own risk).

However, where this battery really shines is when used to power a VV or VW mod. Our experience so far has been that this battery significantly outlasts the high current drain king of the hill Sony 18650VTC5 when used at the current levels (5 amps and below) that most VV/VW mods are limited to. If your VV/VW device (other than a DNA-20/30) can use flat top 18650s (Provari's cannot), then this is the battery you need !
