Stock battery

Is the stock battery strong enough for a few led cube lights and a badlands 5000lb winch? If not would a odyssey 925 be better or would I need a dual battery setup?

The winch will drain the battery pretty quick. My voltage was steadily dropping a small amount even when I was simply pre-tentioning the line. You probably have enough capacity to do one strong pull before you'll have to let the charging system catch up and get it back to full capacity. If you're going to find yourself in a situation where you'll need to use it to pull yourself or others out more than once in a relatively short duration, look into adding a 2nd battery. Most people put them under the driver seat.

The stock battery and charging system will handle the cube lights with no issues. The winch under load will always draw more than what the charging system will produce and therefore will drain the battery after some period of time. Under zero load my Superwinch 4500 is rated to pull 25 amps, and at 2,500 lbs. pull it is rated to use 162 amps. I usually completely unspool my winch after a ride where it was used to wash out the rope and neatly respool it. When respooling I lightly set the parking brake to add some tension and spool in 45'-ish some feet of cable in one shot with the engine at idle and it has never had an issue. On the trail and under a heavy load I've winched maybe 20' in one shot (up a steep hill) and there was no obvious issue.

I think a lot of it has to do with how you ride and how much you will be using the winch. What I consider normal trailriding you usually only need the winch for a very short period of time....maybe only for 1' and unusual to need to pull the machine for more than 5-10'. That is to get out of a rut, over a single rock, etc... Usually I'm not really stuck as I can back up, it's just that I can't go forward over the rock or something. If you are into mud bogging then a different story. Being framed out in peanut butter can require a lot of pulling and the distance can be longer also. Worst case you pull for awhile and let it sit for a minute or two to charge the battery back up (assuming the engine is running). Even if the engine is not running (drowned out in water or a roll over) you usually have enough battery capacity to do a short to medium pull and still be able to start the engine.

I've been a fan of second battery systems for a long time because you never know. I started with a winch and plow. That killed the battery very quickly. I went with a second battery setup with an isolater and trickle charger hooked up between rides and I never had battery issues again. It is the best piece of mind that only cost a couple hundred. I keep the factory battery for starting and an odyssey 925 for the second battery.

I killed stocker in 6 months on my 2015. Light bar, music, lots a winching. Ody 925 single and no issues. Really a great batt. I don't think 2 batts required unless heavy use involved.

If you need the Ody 925 it is nice to have but at nearly 200 bucks... The stock battery runs 30 bucks at Sam's Club to 50 bucks at Napa. I can buy a lot of stock battery's (replace it every year or so) and still come out to the good but then I don't use mine that hard or often.

That's fine and great, until you are 25 miles deep in the mnts. We all have our reasons and uses. I am packing one of those Battery jump air compressor things currently for emergency.

There are a couple of different strategies to a dual battery set up. If you set up two batteries in parallel, they have to be exactly the same size batteries because the way they will charge is like filling up two glasses of water connected at the bottom with a tube. They will fill up equally between them. No matter what you do, they cross-level between them as they drain or fill. This works for people who know they will never drain the aggregate amount of amps to zero.

The other way to set up two batteries is with an isolator. This allows a person to always keep the starting/main battery separate from the auxiliary battery. The batteries will also charge one at a time, as well. It will charge the starting battery first and then switch to the auxiliary battery. This allows for a lot more options. You run your accessories off the second battery and you keep your starting battery at the ready for starting and the draw of those things the factory hooked up to that battery. You can run your aftermarket accessories off the second battery with the engine off with no fear of not being able to start. The dual battery picture is a basic setup of a dual setup with an isolator. You can use two different size batteries with this system. So, a person can leave the OEM battery in and add something like an Odyssey or Optima deep cycle battery. The second picture is a blue sea fuse box I always add for aftermarket accessories and I run it off the second battery. I can get home with a dead auxiliary battery but I always need a charged up starting battery.

I know I oversimplified this by a lot but I didn't want to start a novel here. If anyone is interested, they will probably do their own deeper research. You either know you need a dual battery set up or you don't and most of us don't find out we are the ones who know until we learn the hard way. At least that was what happened to me. Never again.
