There are adapters that allow you to use your Halo Triton batteries with other toppers. However, I do not know of an adapter that lets you use a Triton tank on anything other than a Halo Triton battery. (or possibly a smokless image bat, not sure. BigBen would know)
There are many others who have MVPs, Vamos, Provari, but they are out of luck, as they cannot utilize one of the best tanks.
Someone please correct me if I am wrong.
Which if anyone wants to keep the same thread system, they do sell an MVP model. Honestly though, the halo batteries seem to last longer and the triton tanks just plain work better IMO. I also prefer a warmer vape though, so the bccs si sells might be better for some
