    So even though delayed by a day, I got my 21700 based battery packs today.
    The voltage level button showed 3 lights, so full charge.

    I tested each w/ multimeter:
    1. 19.98V
    2. 19.95V

    They fit cleanly in DeWalt tools & work properly.

    'hopefully' the 21700s' in these packs are new

    Probably decent batteries but they may be overrated on Ah. I bought a cheap 4A 20v Battery for my Porter Cable tools and it lasted a lot longer than the 1.5Ah batteries I was using almost 3 times as long but since it was 2 layers instead of 1 I'm thinking it could just be a 3Ah battery. I'm not sure of the smallest Ah size of 21700 batteries though. Even if it is only 3Ah still a bargain as the 3Ah Dewalt 21700 pack goes for about $50 on Ebay and over $120 on Amazon I think. I have both 3, 6, and 8Ah 21700 Dewalt batteries (not 60v Flex). They make a 10A non Flex battery too.

    The dual layer 21700 batteries get rather bulky and the triple layer 21700 batteries (I think flexvolt 9 and 12Ah) are even more bulky to the point that you may be better off using smaller batteries and changing them out more often.
    I like the 2A 18650 and the 3A 21700 batteries for the compactness from there the larger batteries for hte power. I doubt I will invest in 2 layer batteries any time soon.

    Some good info on Milwaukee packs for 18650 or 21700 used https://www.protoolreviews.com/milwa...ries-compared/

    ..also helpful charger info regarding Amps ect.

    I have Dewalt tools and their batteries are almost identical with the exception of 10A 21700 batteries which I don't see listed but likely may exist in Milwaukees tools. Dewalt also has an 8A battery charger with fan that I don't see a Milwaukee offering.
    With a 10A Dewalt battery I think it has 20 5A 21700s if that were true I can see a 15x21700 15Ah battery in the works in the future.

    Just a bit more battery geekness discussion at the bottom of this page : https://toolguyd.com/dewalt-20v-8ah-...attery-dcb208/
    ..goes so far as describing the lettering for DeWalt packs using 20700 vs 21700 (same Ah)

    Also, high amps vs high Ah



    From toolguyd.com ~ The DCB206 with the 21700 cells will say “6Ah” in large white lettering on its side sticker, the 20700 based battery will say “6.0Ah” in smaller yellow lettering
