The GMC Hummer EV is undoubtedly the most in-your-face and ostentatious production electric vehicle money can buy, and that propensity for excess also applies to its battery pack.
With a usable capacity of 205 kilowatt-hours, the Hummer EV's battery is the largest available on a production electric vehicle at the moment, with only the upcoming Ram 1500 REV set to overtake it with an optional battery pack of 229 kWh.
