I think it just a disclaimer to protect them selves as they use a proper battery tag welder so they should be fine to use unless some one on here knows any different??

I was under the impression that tagging them actually damages the conductive material inside the units in a thermal way, which is what makes them unsuitable for vape use,

I have in the past known of a company that used to take a standard 18650 batt then put it inside a metal case with tags on (altering the dimensions) and called them 19750's to eliminate the chances of causing problems.

iirc there is a way to do it with a zero ohm putty but the stuff is expensive, Alibaba se the stuff but there's only one seller and they demand a minimum order of 10kg's I don't know if its available in the UK in smaller quantities but I would doubt it.

I would suggest a better option would be a different enclosure for the batteries unless your plan is to create grenades

Think its DIY soldering to them thats not so good. I nearly did that for an 18650 battery backup box. Applying heat to the terminals could damage the internals.    

Just wondering if the welding mentioned is heat or electric? And it looks as if its post manufacture. Its a worry I have now about origins of such batts and not sure if Samsung (et al) actually produce them.

they don't, tagged batts are an aftermarket fiddling which is why there not suitable for things like vaping ...
