    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, 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 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.

    Performance Specs
    - DC Internal Resistance = 16.2mOhms (milliohms) average for the two cells.
    - Total energy delivered down to 3.2V at 30A continuous = 4.7Wh (Watt-hours) average.

    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.
