This is only tangentially related to what you say, but I do like reminding people of this when we talk about laptop batteries.

FAA regulations state that single batteries larger than 100Wh cannot be brought on commercial flights. This guides a LOT of hardware development; why do you think the battery in the MBPr pre-2016 was 99Wh?

"With airline approval, devices can contain larger lithium ion batteries (101-160 watt hours per battery), but spares of this size are limited to two batteries in carry-on baggage only. This size covers the largest aftermarket extended-life laptop batteries and most lithium ion batteries for professional-grade audio/visual equipment."

Good point! My boosted board electric longboard has a 99W battery. My ego longboard has a much larger battery and it was a super pain having it shipped overseas.

have you travelled a lot with the boosted? i hear that after the hoverboard fires the airlines sometimes wont allow it on board, even though its under the limit.

I have not traveled with it.
