This cell has been changed. It now runs hotter and at a slightly lower voltage than it did in my previous tests, by several degrees-C, earning it a lower current rating. It appears to be the same cell as used by the 25A version of the Vapcell gold 30A 3100mAh cell.
This QSO has the same top contact structure as the 25A version of that Vapcell but the metal can of the previous 30A version. The crimp at the top is a bit different than both though. I give up trying to understand all the variations coming out of whatever factory makes these. It is a 25A cell now.
The two QSO’s I tested delivered 3156mAh and 3170mAh at 620mA down to 2.5V.
I am ESTIMATING this QSO’s ratings to be 25A continuous and 3100mAh.
Two cells were purchased for the purposes of testing by me.

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: https://www.patreon.com/batterymooch
These tests only note the ESTIMATED ratings for these batteries at the time I tested them. Any battery that is not a genuine Samsung, Sony, LG, Panasonic, or Sanyo can change at any time! This is one of the hazards of using “rewrapped” batteries 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 continuous current rating and keep the plastic wrap and top insulating ring in perfect condition.
Any rating in my ratings tables can change at any time as different grade cells appear on the market, we get swamped with fakes, or new information becomes available to me. Please, never assume that the ratings in the tables are permanent and will never change! Always download the latest version before considering any cell purchase.
