Holley sniper

I think you’re right about the battery. I was just telling the wife that. I ran a toggle guess that will help with an anti theft device. I think I’ll still bypass the ballast. Should I run a diode across it?

I don't understand why you would want a diode? What would it do?
If you're running the OEM ignition then you should probably keep the ballast functional. If you have a system that dies not require a ballast, or you're going to control timing through the sniper, the you can likely bypass it.
We don't have enough information about your install to make the call.
