Samsung INR18650-25R 2500mAh

Weight: 0.10 LBS

Genuine Samsung INR18650-25R 2500 mAh Battery

With a 25 amp max continuous discharge this battery can handle sub-ohm builds down to .15 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 !


  • Flat Top 
  • Nominal capacity: 2500 mah
  • Max Continuous Rated Discharge: 25 amps (at 25 degrees C)
  • Nominal voltage: 3.6v
  • After a fresh charge: 4.2v
  • Cycle info: Capacity drops to 60% after 250 full charge/discharge Cycles
  • Don't discharge below: 2.5v
  • Standard Charge: CC/CV @ 1 amp / 4.20 volts +/- .05v, 100 mA cut-off
  • (Max) Rapid Charge: CC/CV @ 4amps / 4.20 volts +/- .05v, 100 mA cut-off
  • Impedance: 22.15 +/- 2 milliohms
  • Weight: 45g
  • Height: 64.85 +/- 0.15mm
  • Diameter: 18.33 +/- 0.07mm
  • Operational Charging Temperature Range: 0 to 50 degrees C (best below 45 degrees C)
  • Operational Discharging Temperature Range: -20 to +75 degrees C (best below 60 degrees C)
  • You can store them for 1.5 years at -30 to + 25 degrees C, 3 months at 30 to 45 C and 1 month at 30 to 60 C (in other words, store them in a cool place and they'll last longer)

    My first test drive with Samsung 25R's and they are amazing! Getting great battery life using them in an IPV3 Li on a Herakles Plus 0.4 coil at 50 watts.

    Also, as this was my first purchase from Kidney Puncher I did have a few questions before purchasing and their customer support is outstanding! I would give them 10 stars for that if I could...will definitely be a repeat customer!!

    Amazing battery life

    Posted by Jonathan on 13th Nov 2015

    Kidney puncher is without a doubt the place to get these batteries or any for that matter. Using in a regulated device and get days of use. Great price sold by people who you can trust.

    So far, so good...

    Posted by CL on 11th Nov 2015

    Not a bad battery so far...but it's been less than a week. I have a very hungry Provari P3 that disapproves of most batteries. My current setup (Aspire Triton running 1.2 ohm VaporWerx AP204 vertical coils) can easily run this P3 to its limit and many other batteries just can't hold up.

    These seem to hold up just fine and last for about 6 hours of good vaping. If all goes well, I'll be ordering more.

    love these batteries!

    Posted by David Bolinger on 11th Nov 2015

    I love these batteries!! After the first charge, the life of these batteries are about 2 1/2 days in a Snow Wolf 200 TC, using a Heracles ni200 0.02 ohm coil. You can't go wrong with them!!

    Great Batteries for Temp. Controlled Devices

    These Batteries are great. Last longer than my Sony VTC3 Batteries in my IPV 2D & Joyetech eVic VT mini.
