Not a video (yet). Poor battery pack clearance
Added 2024-06-09 01:32:01 +0000 UTCI showed a couple of power tools on the live stream. A different cordless handheld chainsaw, and a cordless air blower. Although all the batteries look the same, the chainsaw one has a much simpler chip, but keeps circuitry associated with classic BMS chips.
It also has a slightly freaky clearance issue between two adjacent battery taps, where a metal tab is above a pad two cells away, and folds tightly over the edge of the PCB (and pad) so close that I could barely slide a piece of thin paper between them.

But it's connected to the same ground plane...
