sony vtc4

ok so I vape high watts (like 80w-200w anywhere in that range but on average probably 100w) and I hear that the sony VTC4 is THE best batteries for that and for a long time, but unnoticed now they have the vtc5, is it better? Worse? Should it be used lower? Can it handle high watts as well...

Hey guys, I have some new Sony VTC4 batteries and was wondering about the following: On the batteries it says "DANGER DO NOT USE OUTSIDE OF BATTERY PACK" I don't recall any of the Songs I've had in the past saying such a thing. Any input greatly appreciated.
