How is this battery free?

  It uses the phone's battery, which is assumed to be something that is already managed.

    Maybe it is too early in the morning or I am just an idiot but how do battery powered cars avoid the "spicy pillow" problem where batteries swell up?

      Good BMS systems which don't stress the battery, limiting max SoC, liquid cooling, not using its peak current draw as often, etc. Also most drivers won't really use that many charge cycles per day or whatever. I easily use like 90%+ of my phone's battery every day, I'll use up most of my laptop's battery when I'm on the go. Both of these devices often sit at a high state of charge and goose the voltages more to get more juice out of the pack at the expense of how many cycles they're good for. Meanwhile it's not like I'm driving >200mi every day.

    So just assume your Baofeng battery is also managed. Tada! Two battery free solutions.

      By "managed", they mean periodically charged and discharged, and kept out of the heat. which is why I don't want to keep a baofeng battery in my glove bod
