Default 48V to 12V reducer necessary?

I have just puchased a 2005 48V Club Car Precedent Champion Edition. I am in the process of converting it into a street legal cart (i.e adding lights, blinkers, etc). I know that the '05 Precedents come prewired for the light kit and all you have to do is "plug and go" but do I not need a volatge reducer taking the voltage down to 12v? Is there one already installed from the factory? Don't beat me up as this is the first cart that I have owned an have very limited knowledge of all things electrical.

This is what I've learned in my short time with my ezgo cart.
The cart is prewired for lights and uses 2x of the 6v batteries in the pack for the 12v. The batteries I have were new in 2010.
I've only had the cart a year and I've installed a stereo and acc port and about to install more lights.
I've learned that the batteries you use for the 12v in the pack will take it's toll and shorten the life of just those batteries. Which will shorten the life of the pack.
So the voltage reducer will draw from the entire pack instead of just a could batteries.
So I have everything on the reducer including the lights. So nothing is drawing from individual batteries.

I'm not sure how much damage it will do with just lights, but if you plan on adding anything else then I'd suggest a reducer.

There are others that run an accessory battery too. Just another battery to charge and not sure what ll you can run on it and how long....
They will comment!

Tenn, in your battery bay, on the passenger side, you should see a blue wire with a connector hanging off the positive post of the front battery. If you purchase the OEM light kit for the precedent, that is where it will wire to for 12v power. That means your lights will be drawing power off of one of the 12v batteries in the pack so no reducer needed. However, this also causes an uneven drain on that battery within the pack and will cause issues later on, sooner than you would normally have them. Also, when the pack gets low and you are riding at night, you'll start the see the lights going dim when you push the accel pedal and eventually go out. When I had mine wired that way, I'd lose my lights before I lost the ability to ride and it sucked.

There are two other options. Install a reducer and wire power from that. If you do that, do it correctly with an on/off switch for the reducer and a fuse block to wire accessories to. Or, install a dedicated battery to run accessories and use in-line fuses to those accessories. The latter is the method I chose. I went to wally world and got a 12v marine deep cycle battery and a battery box and mounted it in the bagwell beneath the passenger seat. I took one of the quick disconnects that goes with my battery tender and wired it to the battery posts and just leave the quick connector hanging out. I run my lights and my stereo off of that battery and now they last longer than the cart does. When I plug in the cart, I plug the battery tender into the extra battery - no big deal.

Good luck and don't worry about getting beat up on here.
