I've flown with the 132 WH Talentcell several times last year.
For some airlines (Delta, American), I was able to find a statement on their website something to the effect that "up to 160 WH is fine as a carry-on."
For Aer Lingus, I called and they said that was fine and they'd let the cabin crew for my flight know about it.
I flew on Southwest in August to Pickathon and had emailed them for permission since I didn't see anything on their website. I got a response from Eugenie.Balounova@wnco.com with a screenshot from their internal customer service website indicating that it was OK. (attached)
Probably a good idea to confirm that their policies haven't changed.
Remember - Carry-on luggage only. And if it catches on fire, pour plain water on it. (Yes, that's the recommendation.)
Hope this helps!
