Need help deciding batteries

[Reactions 10+ year member]

Planning on running 1500 watts. I have a 2013 hyundai elantra so fitting a big battery won't work.

I want to add a secondary battery but not sure if I should just add a rear battery or run 2 xs 950(1 as starter and 1 backup) but I heard bad things about running those types of batteries as starters. What are your opinions?

Do you know if you need a battery yet? If your drop is real bad a battery won't help

Well my H.I.d s flicker and my interior lights dim a bit I haven't done the big 3 but I have a pretty small battery so I thought that was going to help. The wiring was half of a battery so I thought I would upgrade the battery first.

That's alternator getting pulled down. If hids flicker that's really bad. Battery will not help you. Get a dmm and monitor voltage while playing. Back the gain down till its stable. You are going to fry something if you don't.

I already did that, but I can't get it to drop. It only drops when I drive.

Wang on it when parked. You will have voltage drop. If not, there is some black magic going on..
