I'm looking into buying a volt or Halo G6 kit for my wife. This forum seems to be the place to ask for advice since I just started doing research and need more guidance. My question is if I buy the Volt kit can I use Halo cartos with the Volt battery since they are both 808? My only concern is that Halo cartos are made in the US. I want to stay away from chinese manifuctures. TIA
