Who runs 1 battery and who runs two? I'm not having any issues per se with one, but I am considering adding a second as an insurance policy of sorts. I have 2 gauge ran from the battery (right front corner of the truck bed) to the master switch and 2 gauge from master switch to the front distribution block, then 4 gauge to the starter. It takes it's sweet time to spin over when cold, and if it's a bit low on voltage after spinning over, the injectors stop firing due to Vdrop with the starter spinning.

I talked to a fellow at the OKC Divisional in a dragpak, he said he had to go to 2 batteries for essentially the same reason, fuel injectors and starter simultaneously doesn't add up after a couple starts and nudging forward in the lanes.

Once it's warm I don't have any issues. It's just the initial cold start. I keep it on a battery tender, so it's not a low battery issue initially. It just takes 30-45 seconds of spinning before it catches.

Worth adding a second battery?
