You can now buy an adapter for the LTv9 cartomizers. These were made by by Vapure to allow use of LTv9/E9 cartomizers on any 510
device (this has been tested and verified to work by ECF member Mac, who is also an off-line supplier).
I suggest getting the
Mega 510 manual battery since they run 4 hours, or run a mod unit for even longer mAh time. they are a bit longer, but it is well worth not having to recharge a battery every hour! Also, the 510 battery is much less expensive than anything else that would be compatible with the LTv9 cartomizers.
The adapters are available here
510 Adapter I'd suggest getting a few of them since they can go missing easily. It is best to put the adapter on the cartomizer first, then put it on the battery (don't crank them down hard).
As a bonus, you can try out the 510 cartomizers with your new 510 batteries or try the 510 atomizers if you ever decide to change it up. I find both to work quite well and give excellent vapor, flavor and throat hit.
Happy Vaping
