2015 Kawasaki Mule 4010 dual battery install


Recommended Posts

Hi all, I am looking at putting in a dual battery setup to my 2015 Mule 4010. Anyone put one of these in before? Most of the research has pointed me to the True Am kit. Didnt know if anyone had done this or had a battery strap down tray they recommend or anything.  Between the Winch and the Stereo...and upcoming lights I want to be able to make sure it always starts.

 

Thanks in advance,

-Andrew

Okay, I finally found it on  the Kawasaki website, the stock output for the alternator is 15 amps..... I know most lawnmowers that use a electric PTO for the blades put out 20 amps.

Kawasaki still sells the big 50 amp alternator kit for this 4010.. but it's anywhere from $300-500 bucks.

Try an alternator/starter shop. They do upgrades to automotive alternators for a lot less than that. So guys can run the huge stereo amplifiers. I think it's just resistors and stuff. But it's worth a try, since even with the dual battery system. You'll still need the extra amperage. 

Hey Kenfain,  not sure why I didnt get a notification on the post but I wanted to circle back. Thats an awesome idea. Looks like I will have a few calls to make and find a second stock alternator. If I have a high output modified alternator then I can probably get by with just the single battery too.

 

Ill post back with some info after I track down the local alternator shop and talk with them

The dual battery set up is still a great idea. Because the thing about high amp draw accessories, is that the motor needs to be running. Like when using a winch.

I had a nice stereo in a vehicle once. Every time it hit a bass note, the needle would tank. Just keeping time with the music lol.

Not hard to envision that a couple hours of listening to the radio while fishing...you might need that extra battery also.

Only you know exactly what you have in mind for your build. But if you're going over a true 40 watt per channel stereo. Unless you have the dual battery. I'd keep an eye on that amp draw.

         ---------------------------

I sidestepped all that by using a powered speaker. It's portable, and self contained. It'll run for hours. And it's got quality sound, that can be easily heard from a hundred yards away. It'll get so loud, that it can hurt your ears to walk over to turn it down. And it's much cheaper than an installed stereo. Mine was about $125. And its about the size of a milk crate.

Amazon has a 40 amp alternator for your mule for $100.  I'm sure there are other sources for a larger alternator and maybe for a lower price.  That stock alternator is barely big enough to run the headlights and other lighting and charge the battery.  Make sure you install a battery isolator so that if one battery goes down, the other battery is isolated and won't discharge.

      Have a Hisun 800 it runs for about 35 minutes then stalls. Crank's over but has no spark. Let it sit for 15 to 20 minutes and it starts and runs again for about 35 minutes. Changed the CDI / ECU controller and still does it.

      Hello, All!  I've decided to replace the traction batteries in my 2018 Sector E1 with a 48V Lithium set. They may be expensive, but I figure the Discovery Dry Cell are, too. I am not looking for the max driving range, as I have never received near the brochured range to begin with, but a good mix of charge/ get work done/ charge is what I am expecting.
      I have settled on the 48V EAGL kit from bigbattery dot com. Each battery pack provides 30Ah. The kit ships with a charger, as well. The packs would be physically connected in parallel (using a busbar) to one another, maintaining the 48V voltage, but together would be able to provide the amp draw the buggy pulls when going up hill or towing a rake (rated 320 max continuous Amps). This is in comparison to the serial connection the eight 6V lead batteries. Each of the EAGL batteries looks to have its own BMS; am I correct in thinking I will have to use their included charger rather than (simply) changing the onboard charger to lithium mode? The chemistry of the pack is LiFe PO4, for what it's worth.  I haven't torn anything apart yet (to diagram), so  I am not sure how the dash will interpret the AMP draw, but the kit I am looking at includes a dash mounted charge indicator.
      If anyone has completed a similar conversion, do you have any tips? Specifically, how did you remove the original batteries, and how did you secure the new ones? I am guessing that almost any change from the stock batteries would involve at least some modifications. Any tips would be appreciated, especially things I may have failed to consider. Thanks!

      Just got this kymco 450i Uxv from a guy, drove it around before I paid. Got home drove around town a little while the next day and it started squealing and amd didn’t want to go. Got to looking at the clutch, that’s were the noise is coming from, the primarily sounds like. Maybe a bearing in there cause the grinding noise and it only makes the noise when you go to move.

      Less than 40 miles can barely start. Dealer is working with Hisun on a number of other issues on this UTV. Can not get clear info on the meaning of these E codes this is getting. Anybody have some clear info for me?
