Just found this on 18650.uk when i was looking for batteries:
“Please note, LG Chem are now shipping some of their HG2 batteries stamped with a notice that they are not for E-cigarette/vaping use. The battery itself and its build/chemistry has not changed, LG are simply not endorsing their products for use in vaping.”
All they are doing is to release them from any liability from mis use of batteris…some people do not practice build an battery safety and end up on the news…then want to sue any one they can…so LG protected themselve…I think sony has some thing also on thier battery or may be Samsung…
Well… isn’t the point of releasing specifications that the user can decide if it is suitable for the application he wants it for? If the specs say discharge 30A and my vape only goes up to 10?
I think this is more of a statement rather than a protective measure.
