The FAA limits allow up to 160 Wh within a device. A Thinkpad T430 with the 9-cell with a Slice battery pushes that to 188 Wh, and no one seems to question it.

The FAA limits allow up to 160 Wh within a device.
A Thinkpad T430 with the 9-cell with a Slice battery pushes that to 188 Wh, and no one seems to question it. You can also bring spare batteries (not the same as an external battery) to plug into it.
The MacBook Pro is not pushing these limits. They have a glued-in, non-replaceable 49.2 Wh battery.
Your best bet at this point may be an external, but users would be better off if manufacturers offered machines with large, replaceable batteries.
