How many sets of off road lights will run on a single battery ????

[4508js]

Hello all I have three sets of 100w KC lights on my H3 (one set of driving beams and two sets of fog beams) but I haven't wired them in yet, I was just wondering if my single battery is enough to safely wire my lights in ? I will be using the furnished wiring harness and switches, here is a picture of my setup. Thanks for all your info in advance.

what kind of battery are you running? optima yellow top? die hard?

It's actually more an issue of the amp output of your alternator. The only way your battery would get really taxed is if your alternator was unable to keep up with the draw.

6 100w lights would be 8.33amps each, soo 50 amps total (rounded). the output of the stock h3 alternator i think is 145 amps, add on all the other draws that the car has, you might be pushing it.

That's the biggest reason I got LEDs. I still have my KCs but the Rigids do the bulk of the work

Damn, what a fine looking rig! I like the color!

Thanks Paladine, the badazz KMW roof rack, ladder, and the S&G predator Brushguard definitely makes it look very cool. I'm not sure about the battery because it has the factory cover over it and I haven't had the time to take it off, I'm assuming its probably the same as a factory battery. I'll try to make time to get all the info on the battery then I'll pot t here. Thanks guys

I did a double take looking at your rig as it looks a lot like Paladine's - and that's a good thing!

okay well i think its safe to say you are going to have to get a bigger alternator. But, are each light 100w or is 100w for 3?

 

[alrock]

KCs are either 100w or 130w each depending on which bulb you get.

 

[4508js]

These KC's are the Apolo series lights with the 100W bulbs so each individual light is 100 watts and I have three sets. So my question now is what's the better route, a bigger alternator or a dual battery setup ?

 

[Scarsman]

I would start with upgrading the alternator first, and maybe plan on a second battery eventually.
