What are rules for international flight + Ebike Lifepo4

[jag]

I think they allow tool batteries and spare electronics batteries if they are in 'original cases' or plastic bag.
Apparently they don't want them in check-in bags, they prefer carry-on ( theory is they can deal with it on
the plane then ). But the rules are fuzzy.
So nobody travels with their bikes or scooters overseas anymore?
I've taken a go board with built in lead acid cells, but that was 3 years ago. Great for zipping around those
sidewalks. I guess I can try to find a couple of gel cells over there. ( Eastern Europe ).
I'm surprised there isn't more info on this. I guess people are pretty listless these days.

Does anyone have recent actual experience flying with batteries? I read the rules on:

Seem like I could take my eight 28V DeWalt batteries in the carry on since each is under 100Wh so under 8g lithium.

Update on my experience at DCA/Reagan National Airport in Washignton DC: Had 4 DeWalt 8s packs (28V 62Wh each) along. Packed Dewalt in carry-on (separately from other bike parts that were put in a bike box and checked in). Batteries in the carry-on were indeed spotted on xray and I was asked to unpack my carry-on. The security clerk briefly looked, we chitchatted about RC hobbies and I was on my way again in just a few minutes.

In case of any trouble I was prepared with printouts from government web pages showing I was allowed to carry assembled battery packs each under 100Wh in carry on luggage.
