@isagalaev@mastodon.social Yes, watching sailing or off-grid type videos and having somebody talking about “100 amp” batteries and really not being able to tell if they actually mean batteries rated to produce 100 A or if they mean batteries with a capacity of 100 Ah. The error is so common expressions either way are ambiguous without more context.

@edavies@functional.cafe and amper-hours is its own sin. Battery capacity is watt-hours, but when voltage is constant in some context, sure you can divide Wh by V and get Ah. It's usable, but… why??? Why not just use a standard unit :-)
