Perfect for vaping in variable voltage/variable wattage VV/VW vaping rigs, I use them in my Vamo's they last for almost 2 days before they are depleted, good batteries for the price, I recommend higher max amp batteries for vaping in mechanical rigs though.

Arrived on time... Worked perfectly. These are protected batteries and they have a good long life. They work well in my nemesis mod

Definitely the best High Drain 18650's out there!
I have quite a few high end lights that I use 18650 batteries for so I do plenty of research and always purchase only certain battery types. To name a few of my devices I have a Surefire P3X Fury 1000 Lumen with barrel extension so that I use 2 18650 batts instead of 4 cr123, a Taser Strikelight a stun gun and flashlight in one, and a Wicked Lasers Arctic Spyder III the worlds 2nd most powerful handheld laser, and I need reliable best in class performing batts that won't be exploding or leaking in my devices any time soon. For my normal rechargeable protected circuit 18650's I use mainly AW but will settle for Tenergy or Panasonic batteries. For unprotected high drain batteries you can't get any better than IMR high drains! They are very reliable have a reputation for safety. I would recommend these batteries highly to anyone!
Please understand the difference between Protected and unprotected High Drain batteries before you order these. Most people and flashlights will only need Protected batteries, but there are some use case scenarios where a high drain batt is desirable. I purposely ordered these with the flat top instead of button top so that it is harder to accidentally short them out in storage,

not sure if these are fake or not but they do NOT last as long as a 2000 mah battery should.
yes its running max output 4.2-3.7v all the time in my mechanical ecig but they dont last very long. not a full day.

Number 1: This is a great price that you can't miss!
Number 2: Refer back to number 1!

Since I am using a APV I don't have to worry much about over discharging. EFest was highly recommended to me by a friend aside from the Sony VTC4. One thing I realized after purchasing these are that they're maxed at 10A unlike the VTC4's 30-34A load. Nothing to worry about using a VV/VW device that only goes up to 15.0 Watts/ 6.0Volts. Actually getting a DNA30 soon. Can't wait to try these out on that!
