    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
    While this cell has a useless large 40A “max” current rating on the wrap it has an accurate continuous current rating. Its capacity rating is slightly exaggerated though.

    I am thrilled that the continuous discharge rating (CDR) is mentioned on the wrap but I hate seeing the use of a “max” current rating. I hope Golisi removes the max rating soon.

    The two cells I tested delivered 3112mAh and 3181mAh at 0.5A down to 2.5V.

    These cells performed well, essentially equal to the Vapcell gold 30A 3100mAh 20700 cell.

    I am estimating this Golisi’s ratings at 30A and 3100mAh.

    Golisi wanted our community to know that they have product liability insurance for their batteries. I don’t know the specifics of what benefits this offers to vapers or vendors. Contact Golisi for more information.

    Two cells were donated for the purposes of testing by Golisi (Home). Thank you!

    Performance Specs
    - DC Internal Resistance = 14.7mOhms (milliohms) average for the two cells.
    - Total energy delivered down to 3.2V at 10A continuous = 9.0Wh (Watt-hours) average
    - Total energy delivered down to 3.2V at 20A continuous = 7.8Wh (Watt-hours) average
    - Total energy delivered down to 3.2V at 20A continuous = 5.8Wh (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.

    Golisi 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 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 payment.
