    I would love to see a 5/10AH or 6/12ah multi volt battery for High demand tools like the miter saw, vacuum ETC …..That said these new 18 V batteries are long overdue, MV packs aside, their haven’t been any updates to the 18v batts since being under the Hitachi name brand if I recall,
    so imo they were long overdue to be upgraded and they didn’t disappoint. Seems like a solid new revision & I really like that they finally caught up with the times and started including the fuel gauge lol. Aesthetically, they look more refined & modern, similar to the Multi volt packs but 1p instead of 2p so they look like a shrunk down version of the 36V packs….. But the real question is do these new 1p 18v packs have 21700 cells like the 36V? doubtful but either way the durability, quality, value, warranty & unmatched customer service IME, you just can’t go wrong with MHPT… Now if they’d only release some of the tools they sell in Japan only.
