Sorry if this seems obvious. RDA question

[Jp20]

Hello all, I don't like to assume things, so I figured id asked before a purchased an rda. Im looking at a bunch of cheap ones to get started on, But the ones I feel would look most decent on my Vamo have two negative posts. Can I only build a dual coil on these or can I leave one of the negative posts alone? I don't think I want to start off building dual coils. Thanks in advance.

Ya you can use them for a single coil just ignore the second post
