Trigger - I've read your post about dual batteries. I too feel that hooking two of the same in sequence is the way to go. I have a P1k, would you happen to have a diagram, some pic's? Is it the same as hooking up two 6volt's in a camper?

Just don't wire them in series, that wouldn't be good!
There is a difference between starter batteries, what you have in cars/trucks/tractors/SXS’s and deep cycle batteries like you see in boats/RV’s/golf carts and solar cabins. It’s crucial that deep cycle batteries are married to identicals, and not so much start batteries. So it depends on what you’re after.Trigger - I've read your post about dual batteries.

On my SXS, I have the rapid cycle 16 AH stock starter battery for all OEM equipment, and a 36 AH deep cycle for most accessories. Rapid cycle starter batteries don’t like going below 20% discharge without loosing voltage, whereas deep cycle batteries can go all the way to 80% discharge before dropping voltage. So I can set out by the fire listening to my sound bar, drinking beer and roasting hotdogs while my auxiliary battery goes into deep discharge without issues.
Batteries in parallel maintain voltage and increase amperage, batteries in series double voltage. Whether using two starters or a starter and a deep cycle, you need to be in parallel.
Haha, you’re right, I left out the crucial isolator that we have in our systems. Thank you.You are absolutely correct about the starter vs deep cycle.
I feel like I missed you mentioning it but that is where the isolator comes into play. It keeps the starter battery charged and allows the deep cycle to power the winch. Occasionally you have to let the deep cycle catch up the alternator CAN NOT keep up with winch draw, the alternator is only @38Amps a 4500lb which can draw over 300Amps.
Ha point, or a 24V PV House.Unless you are wiring up a 24V Land Cruiser

You could probably carefully manage your usage with your stock battery, but IMO, the dual system is cheap peace of mind. As ohanacreek pointed out above your alternator produces less than 40A and that winch draws hundreds, so if you had a long recovery or work out with your winch, you could find yourself in a bind. My two centavos.Thank you gentlemen. This is my first SXS and I am learning so much reading all your posts.
I know I've read this some where in here,but, do I really need a dual set up running 4 Led's (2 - 4" front and 2 back), a 4500lb winch? I may install a stereo later.

Yep, on my P5 I used a Perko switch (like you find in boats and RV’s) Not a True Isolator. As I said To Jiggs, it depends very much on what one is doing and wants. My winch comes out at most every 20th ride, whereas I can be found setting by a bon fire on my ranch drinking beer and running down my auxiliary battery quite often.Pretty sure that isolator is a crucial P1 clutches thing and not necessary on the P5? Even then I can see the beauty of a manual switch where you have total control but that True one limits your electrical system IMO.
Say your not roasting hot dogs but winching out of a hole where the engine is stalled, once the aux battery is spent you can't even utilize that full starter battery? And that aux battery was probably light anyway from doing short runs and never seeing any charge.
Yep. I need a beer drinking back up battery as soon as I install the stereo.Yep, on my P5 I used a Perko switch (like you find in boats and RV’s) Not a True Isolator.

SEE!!! You’re thinking straight my friend.Yep. I need a beer drinking back up battery as soon as I install the stereo.
Lol! Yes Sir.. So it's fine to add a deep cycle as long as I connect in parallel? Sorry for all the repeated questions, my only excuse "I'm a Logger" haha..SEE!!! You’re thinking straight my friend.
Yes, in series you’d have 24V..... Remember, in a starter/deep cycle scenario, your deep cycle powers your fuse distribution center for your accessories. The Perko switch is ideal for this set up, you isolate the starter for extended use, a long winch recovery or a few brewskis and tunes by the fire. On mine, starter is 1 and accessories is 2. It can be in the two position to discharge and then switched to 1for a quick start and back to combine for recharge. And there’s always a tender on it when it’s parked. Also, I keep a hot box in the rear deck kit for an eventuality with my own or someone else’s.Lol! Yes Sir.. So it's fine to add a deep cycle as long as I connect in parallel?
