These tests below only note the ESTIMATED ratings for these batteries at the time I tested them. Any battery that is not a genuine Samsung, Sony, Murata, LG, Panasonic, or Sanyo can change at any time! This is one of the hazards of using “rewrapped” or batteries from other manufacturers so carefully research any battery you are considering using before purchasing.
Misusing or mishandling lithium-ion batteries can pose a SERIOUS RISK of personal injury or property damage. They are not meant to be used outside of a protected battery pack. Never exceed the battery’s current rating and keep the plastic wrap and top insulating ring in perfect condition.
Testing batteries at their limits is dangerous and should never, ever, be attempted by anyone who has not thoroughly studied the dangers involved, understands the risks, has the proper equipment, and takes all appropriate safety precautions.
If the battery has only one current rating number, or if it only says "max", then I have to assume the battery is rated at that current level for any type of discharge, including continuous.
Bottom Line
This is a fantastic performing cell, easily beating the VTC5A and essentially performing the same as the 18650 VTC6A. The Samsung 20S still hits harder for most of a discharge at high current levels but the 20S’ lower capacity rating means that eventually this cell (and the VTC6A) run for longer as the voltage drops.
It’s not a Samsung, Sony, etc., rewrap and doesn’t appear to be a China manufactured cell. I think I know which cell it is but I need to do some other testing before I can say anything definitive. Hopefully it becomes more widely available soon as it’s a great performer for both regulated and unregulated/mechanical devices.
The four cells I tested delivered 2656mAh - 2672mAh at 500mA (0.2C) down to 2.5V. This is very good consistency.
I am ESTIMATING this Vapcell’s ratings to be 25A continuous (about 75W) and 2500mAh.
Four cells were donated for the purposes of testing by Vapcell (Vapcell batteries, chargers, vape batteries). Thank you!
Continuous Current Discharge Graphs

Performance Specs
DC Internal Resistance = 17.4mOhms (milliohms) average for the two cells.
Total energy delivered down to 3.2V at 10A continuous = 7.9Wh
Total energy delivered down to 3.2V at 20A continuous = 6.3Wh
I want to work for the vaping community full time! If you feel what I do is worth a couple dollars a month and you would like early access to battery availability and testing news and a say in what I test then please consider becoming a patron and supporting my testing efforts: Battery Mooch is creating battery tests and educating vapers | Patreon.
Vapcell paid a fee to be moved to the front of the testing queue, which currently has a 10-12 week backlog. This cannot influence my test results as this is science, not a subjective review. In addition, they pay in advance, have no say about what is in this report, and I don’t care if any company never does this or donates batteries again. My reputation is a lot more important than any battery donation or fee to be moved to the front of the queue.
