    While the test results are hard data, the conclusions and recommendations I make based on these tests are only my personal opinion based on my criteria for setting a rating. Carefully research any cell you are considering using before purchasing.

    Testing cells at their limits is dangerous and should never, ever, be attempted by anyone who has not thoroughly studied the dangers involved and how to minimize them.

    If the cell has only one current rating number on it, or if it only says "max" then I have to assume that the company is stating that the cell can be discharged at that current level in any way, including continuously.

    Bottom Line
    This “35A” cell is so overrated I am again at a loss for words. This AWT appears identical, and performs almost identical, to the not-so-great performing Samsung 35E. I rated that Samsung at 8A.

    AWT’s 35A rating is even useless as a “pulse” rating. The first pulse at 35A on a fully charged cell dropped the voltage to under 3.0V.

    The wrap has “IMR 18650” on it but this cell does not use the battery chemistry often associated with the IMR model number prefix. It uses the chemistry associated with the INR prefix.

    I feel strongly that each of us is free to buy whichever batteries we want but I urge you to consider whether or not you want to support a company like this.

    I am rating this AWT at 8A and 3500mAh. Its maximum vaping amps (MVA) limit is 13A, limited by voltage sag. For best performance I recommend not using this cell at over about 5A, 15W-20W or so.

    The two cells that were tested were purchased for that purpose by me.

    Pulse-Current Test Results
    Pulse testing was not done due to it being a 35E rewrap.

    I thought that 8A was a typo, I just couldn't believe it.
    They need to make toxic chemicals, seems more up their alley.
    Thank you Mooch for looking out for us.

    I get the feeling that AWT execs torture kittens as a bit of light relief from dangerously exploiting their unwitting customers.

    Oh c'mon... 8A? :eek:

    There's ludicrous, then there's Efest, then there's "beyond the pale"... then there's this. :mad:
