    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.

    (Sorry for the split link but direct links to Imgur do not display properly)


    Bottom Line
    This cell has “35A” on the wrap, a useless overrating. It’s not even close to its true rating and can’t be a “pulse” rating because we don’t know the pulse length, the time between pulses, or the criteria used to set the rating. This means we can’t use the rating to compare this battery to any other…it’s useless.

    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.

    This AWT performs identically, and appears identical to, the Samsung 30Q. I am rating this AWT cell at 20A and 3000mAh. Its maximum vaping amps (MVA) limit is 25A, limited by temperature.

    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 30Q rewrap.

    Thank you Mooch for taking the time to test this bat.
    When will this rewrap to Armageddon end?
