Finally reached the limits of the amount of power it can pull. My headlights started flickering. Anyone have any experience running dual batteries? Plenty of space behind the center piece on the dash. Saw this kit also, intended for can am but should work with our machines.

What all accessories are you running.
I have a winch, swamp donkey stereo, and my whips and roof light bar come in this week. Is this going to be to much for the machine?

Yes sir, I’m running the same as you but without a winch. And an amp and subs. The light bar was the one that tipped it over the edge. Everything functions perfectly with it off. Intermittent use is ok but I’m not happy with that. I figure dual batteries is a lot cheaper than a $600 alternator plus labor and most importantly concerned about it getting wet or under water while on the trail.

Completely agree

Makes a lot of sense... way too much money. Why Kawasaki put such a low voltage system in is beyond belief.

So, I could see some how a box being fabricated to house a battery in the dash near the bus bar I just lack the tools for that kinda fabrication. Any other ideas where to put one if not there

I think you can buy a “battery box” just finding a place to secure it would be tough. I’m sure there’s some metal down there somewhere it can bolt down too. Here’s a quick amazon search.

Yea really all it would have took is for the stator to push out more amperage. But just like everything on this machine it seems like it’s designed that way so you go and buy more accessories. The fender flare option set me over the edge, those should have come factory equipped.

I ran out and thought maybe there’s space under the seat for the other one. Sure enough there is. The battery is a 96R. Instead of setting it in there horizontally, I think 2 of them will fit in there vertically, granted a plate is made at the bottom to hold them. I’d probably switch to a sealed battery too to get rid of all the extra vent hoses. If they don’t fit then maybe downsize a battery with the same ratings.

 

[Jlhens03]

That was gonna be my next question. Would a optima battery do better and prevent having to switch to a two battery system. I haven’t had time to look all this stuff up yet.

It’s not so much the performance of the battery Output (Cranking amps) it’s the amount of power storage. Once the battery hits rock bottom is when stuff starts cutting out. Unless there’s a high capacity battery?

I put the alt kit on first month on purchase.. the install is not that involved and would be glad to help you through it.. as for submurged.. I ran up a creek up to the doors, in the snow, psi wash it down and no issues.... even if I did fry it I crossed the part # of it to cross to same one off a Kabota tractor recon available from auto zone for around $70...also second battery should be the same rated cca.. so yea kinda looks like one could with some work squeeze one under the seat.. but why fight it..its unfortunate that the stock krx rectifier won't sustain the draw of the accessories but my dealer was upfront about that on purchase.. if your anticipating a blower taking the pto space.. my take.. by the time they ever come out with a blower kit and at what cost.. you maybe able to trade up on a new release machine that Is already turbo'd .. my alt kit has worked solid.. I run extra lighting, stereo blasting, amps, sub, heater kit on, wiper motor, rugged,,without a second thought.. I never have to worry about a low battery and seldom bother with the tender..

This is awesome info. Can you share that cross part number for the alternator?

 

[Ajb9]

its a Denso 101211- 2181 / 21001-0647

Any chance you had a link or another way to find this part. I haven’t had any luck finding that alternator. Thanks!

 

[Ajb9]

There is more to it than just an alternator.. there are several special milled brackets, drive components, pulleys, wiring and ect in the kit. if you want to run a bunch of electrical accessories without damaging something from low voltage the alternator kit is what is required and kawi is the only place to get it.
pull the trigger and move on you'll be glad you did!

My .02 cents. I haven’t yet hit the limit of the stock charging system. I’m running just about everything you could imagine except a winch.

Had a battery for overlanding in the fj80 i dont have anymore laying in the garage on a batterry tender and thought hey lets give this a try!

I WAS SO CLOSE.....EPIC FAILURE. Good thing it only cost me time and I learned some things.

So then I came up with another idea on mounting it behind the seat but i would need to raise it 1.5 inches with the batterry support bars. Test battery has like 76ah storage and 880 CCA. Which is a little much but it wouldnt destroy anything.

I think the best idea would be to go with a pci1200 AGM battery as it is almost the same size as the stock battery and has 40ah and 550CCA. That doubles storage. Lots of canams running them and they sure love their lights and loud music.

I appreciate your hard work on this discovery! Been wanting to do that for a while. Will look for the AGM
