Hello Jim,
This is the story:
I'm going for long hikes with my electric scooter (2 or 3 days), I'll have to change the battery for a new fully charged one at some point.
That means opening the deck, uncovering all the connections, the control cards...
I suppose with all the friction of the air on my synthetic clothes, my long hair, there is a risk that I will be charged with static electricity.
I would prefer to discharge myself as much as possible, before handling the lithium batteries, putting my fingers in the connectors near sensitive components...
