Flex-volt batteries with travel caps, that have combined Watt-hours that exceed 160Wh, will not be permitted to travel on passengers’ aircraft from 20 March 2026.
AvSec previously considered the flex-volt batteries, including DeWalt Flex-volt, as three separate batteries contained in a single case separated by a plastic [transport] safety cap. Advice from AvSec’s Dangerous Goods Regulator confirmed flex-volt batteries are not three separate batteries but are instead a single battery that exceeds the allowable Watt-hour limits. This advice has been informed by international practice where the majority of National Aviation Authorities and airlines treat flex-volt batteries as a single battery.
AvSec removed more than 282,816 batteries from passengers’ carry-on and checked-in luggage in 2025. Make sure your batteries leave the airport with you, and check the restrictions before you travel.
