    Teardown specialists Munro & Associates are currently taking a Hummer EV apart and have published a video showing how its battery pack is constructed.

    They guys seem pretty critical of some of the construction and materials used - and a lot of their points seem legit - but I think it's important to remember that this is a one-sided conversation. There's no one from GM to say why it's made like this.

    It does, though, score pretty low on their chart of gravimetric weight (Wh/kg) comparison, so I'd say there is definitely room for improvement.

    It does much better on the volumetric Wh/L comparison. However, that's not an especially important metric (in my mind, at least), since space isn't really a significant constraint.

  3. HVACman on HummerChat is going to do a comprehensive review of this video, point out all of the innovations GM is doing and the flaws of Monro's overview of GM's pack.

    Here is just a snippet of his first impressions. He will get to more when he has time.

    Thanks for sharing! Just wish @HVACman posted here as well (he last posted here in 2019, I believe, though he occaisionally contributes to the InsideEVs site).
