Baja ditch lights draining battery

I have 2x Baja Designs Pro squadron for ditch lights and 2x Baja Designs Pro squadron for fog lights. I just got the ditch lights wired today and went somewhere dark with them all on for a few minutes. I saw a coyote. But I noticed my battery dropped significantly from 13.6V to 13.0V. It was still dropping when I turned it off, dropping over the course of 3 min or so.


Is my setup too overkill for my battery and alternator (I know pro is overkill for lighting) i got a good deal on them so that's why I don't have sports. I didn't run them for long, I didn't want to draw too much on my battery. I have the ditch lights hooked up individually as well, so I can power whichever one or both. I'm concerned I might cook my alternator or drain my battery.

I have a napa AGM battery on my V6 Tacoma

Thanks

 

Was the truck running?

They won’t be overkill for the battery

 

Yeah the truck was running (parked) and it was dropping

 

They are LEDs… they only draw like 3 amps.

 

with all 4 running you are around 12amps. by any chance were you just idling? you will be fine driving,

 

Yeah I was idiling and was watching it drop so I was a little worried. I don't plan to drive with all 4 on but I just wanted to make sure it could with all 4

 

at idle you arnt producing full amps from the alt. so you should be fine. I know guys running 5 LP9s and a few other lights with little issues when driving.

 

It's not the lights, where are you getting your readings from?

Squadron Pros draw 2.9A each, so you're only pulling 11.6A total.
I used to run 4x Hella500 at 4.5A each so around 18A total - that didn't even dip the rpm at idle.
My 22re used to run 4x 100w halogens - 33A total. They got hot, and they sucked the rpm down at idle, and they were still fine for 12 years..

Look somewhere else.
