"batteries are much smaller than the exhaust, engine and transmission of a car, but also much heavier."

Excuse me, have you tried lifting an actual engine, lately? I want you to find me a car battery that weighs more than even the engine block alone, no pistons, cams, heads, nada.

A Tesla battery weighs 1200 lbs vs ~500 lbs for an ICE.

Are you sure? Most Ford V8s come in at around 500 lbs.

My vehicle curb weight is 4,374 lbs with engine installed and 2,686 without it. You can subtract another 280 for the transmission for a non-mobile weight of 2,406.

With the additional equipment I've got atop the engine, the vehicle breaks 4,500.

I've got the scale and shop.

He is referring to the battery packs used to drive EVs. Those are in the range of 100kg to past 400kg. Auto manufacturers have been desperately trying to shed weight from cars. it is one reason why most are slowly moving if at all into pure EV and still moving on hydrogen or other fuel cell.

plus many small engines stripped of power accessories can be carried on carry on luggage

Yea, SMALL engines. The engine in my Explorer outweighs the Tesla battery pack by about 200kg.
