52" Light Bar? Running Dual batteries anyone?

I installed this light bar Sunday and just wondering if anyone is running dual battery set up and maybe upgraded alternator for one light bar?

 

I've got a 52" and I've just got it wired up to the battery, no problems yet!

 

Cool was hoping so I wired the same way but had the ac on the headlights and the bar and seemed to drag it down a little?

 

Ya man, I ran from battery to the relay and relay to switch and switch to the bar. Like I said I haven't had any problems yet

 

Cool thanks for the feedback man

 

No problem buddy!

 

LEDs don't pull enough power to warrant a dual battery or upgraded alternator. Sure they're a good piece of mind for longevity if you add more lights/accessories, but I've got a 20" bar, 2 flush mount floods, 4 pod floods, and 2 single row strips on my truck all ran through a Blue Seas fuse block off the main battery. No issues.

 

Thanks Ted. Hell maybe i will just add more lights

 

I have a 50", 20" & 2 pods, also a fan for the a/c condenser, with all on there's not much of a voltage drop(I have one in the cab) it's maybe .3-.5V iirc. I was worried too but it's fine, the idle drops a little but that's expected with a load.

 

I have a 50" and two 20's that I use all at the same time and no issues with stock battery and alternator.

 

Thanks guys..

 

OEM charging system are sized to to handle 120% of the anticipated OEM electrical load and normal driving habits. Check the charge on your battery the morning after and see if it is fully charged. If not, the undercharging will cause lead sulfate will gradually build up on the battery plates robbing it of it's cranking performance and capacity.
