[QUOTE="metalheadjoe, post: 8736590, member: 581422"] I was in the same situation recently (5kw and 320a alternator), and I went with a JY Power HP-40 battery. I didn't do research to land on that battery, but it was what a local shop recommended (alcohol may have been involved). I trusted the shop owner's opinion, because I've known him for nearly 20 years and he's always been passionate about car audio. It is not the cheapest option by any means, but I am very happy with the performance. No headlight dimming running full bore. As for running batteries together, I refer to this article: [URL]https://www.jypwr.com/blog/how-to-wire-agm-and-lithium-batteries-together/[/URL] I removed my underhood battery from the circuit. I think an isolator would be a better option, because I can't see a downside of having another battery as a buffer at peak demand with the engine running, but I went with JY's recommendation. Please share what you wind up going with. [/QUOTE]
