    Just to put this in perspective this has crazy high capacity expensive 20x 18650 batteries in there.

    I can understand the pricing.

    The normal batteries use 18650, but the high output batteries actually use the 21700! (which gives them the 50% power boost)

    12ah wow. That's insane. Only thing is, I don't like swapping batteries between tools whilst working. So would need 5 or 6 of these 😬
