Hello, I think that you do not have any problem bring with you any cartridge, but you need to take it out your suitcase for scannig, because you need do it with all electronic devices that you bring with you, like your phone, that actually include battery too.
I cannot confirm, but there are difference for remobable battery devices and for not, you must remove all batteries but only if you can.
I bought some carts from Japan to Europe so many times, and I do not have problem with it, with and without battery, I never check about it have or not

, but usually I put in my checked baggage.
I think that it is not change so much in this virus times, but I cannot confirm to 100%. Check your airline website, and if it is not clear, send they a email. But I think that you do not have any problem with it. Probadly if you forget put out for scanning, they stop you and open your luggage for check what is it. it is all.
Regards.
