US bans lithium batteries from cargo holds on passenger flights (TechCrunch)

While passengers won’t be required to change their behavior under the new ruleset, consumers may notice that batteries and charging devices shipped to them may arrive without a full charge.

This may also affect photographers travelling to workshops. I have four batteries for my Fuji X-T2. If I needed to bring along several lenses, a laptop, tripod, iPad Pro, iPhone battery pack, etc., I know this stuff would not fit in a carry-on bag.
