Battery Thoughts:
In a better timeline we would have a standard format for low/medium voltage battery packs that could be used generically in lots of different pieces of equipment. Imagine if instead of every power tool, ebike and portable power pack having different and incompatible batteries, you could instead purchase universal battery packs in different sizes from different sources that could be used with anything you owned.
This thought brought to you by a hurricane. Oh, I won't be needing these ebike battery packs while there is a storm rolling through but it sure would be nice if they could be used to power other things if the power goes out.
