    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 is a great performing cell. Until now the only 30A 18650’s we had were the 1500mAh LG HB2/4/6. The Samsung 20S not only has increased capacity over those cells but it performs MUCH better too, giving us a lot more vaping time at high current levels.

    It hits harder than any other 18650 down to about 3.3V and appears to have a true 30A rating.

    At lower current levels, under 20A or so, there are better higher capacity choices. But at 30A the Samsung 20S is the clear winner. In the 20A-30A range it is a close race between the 20S and the VTC5A/5D/6A. You’ll have to test them to see which performs better for the way you vape

    I don’t have the datasheet yet to know Samsung’s ratings but I am estimating them to be 30A continuous and 2000mAh. If needed, these ratings will be adjusted once I see the datasheet.

    Two cells were purchased for the purpose of testing by me.

    For anyone intrested, these cells are now available from Ecolux for only £5.89 each, which is cheaper than the vapcell 2000mah 38a rewrap version of this cell which is £6-£7.50

    is there EVER a reason to purchase a "re-wrap" battery?? It seems a pretty good rule of thumb to just stick with the mainstream electronics companies, i.e., Samsung, Sony, LG, etc.)
