Welcome to ECF! Halo uses an 808 D-1 connection for their
batteries and
tanks. In order to use your Halo
tanks on your Vision Spinner, you'll need a 510 battery to 808 D1 adapter. While that will work if you mainly want to stick with Halo, I do recommend that you switch over to more batteries like the Spinner. The Spinner uses much more common 510 and Ego connections. This will open your options for toppers and batteries. Halo does make quality devices though, if you just want to stick with them. Another company that uses the 808 D1 connection is Smokeless Image.
