Add a battery under the seat of Mule 2500 or 2510

Hi, Has anybody installed another larger battery under the drivers seat of their 2500/2510? I am installing a diesel fired cab heater and need a 12v deep cycle battery to operate the heater like without affecting the stock charging system.  I'm sure I could fabricate something but I have to believe that somebody has already put a battery in this location.  I was wondering what the battery support brackets might look like or even if somebody made a kit to put a battery in this location. Thanks, Mike

I put one under the seat of my Massimo 500 with a battery isolator and an inverter in order to run the winch without draining the main battery and also have 110v available for other outdoor tools and such. I did not use a deep discharge battery because of the finicky nature of the charging of these types of batteries. They are easily damaged if not charged correctly, especially the new lithium-ion units, requiring special chargers.  The primary alternator charges the secondary battery as well as the primary. but the isolator rejects the feedback when the secondary battery is in use. I also have a by-pass switch installed to throw the secondary battery into primary service should the primary battery become disabled.  

The one concern I see about the installation you propose is that 8KW is allot of heat. A common milk house heater is 1.5KW. I have a 10KW propane heater in my 12'x24' shop and keep it 80deg when it's 10deg outside. It's insulated but still. Looks like a good unit though.

Yes it is a lot of heat so it should warm up quickly. The battery draw is quite high at start up at 10 amps to power the glow plug for 1-3 minutes until combustion is established with only the diesel fuel so I want to have a separate battery just for that.

This has to be by far the lowest cost and most effective way to heat a UTV. Especially one that is used for short trips. Using the remote control I will fire up the heater 15 minutes before getting in my Mule so it will be all warmed up before I get in it while the engine is still ice cold and will keep the Mule toasty with the engine off say whill gutting a deer or loading up fire wood.

Looks like I will need to fabricate bracketry for the heater's battery. No big deal but if somebody had already done it that would probably save me some time. That's why I asked if anybody had already done it.

Thanks for all the input!

      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!

      i purchased a brand new massimo tboss 410 and from day 1 it wont operate in reverse.  When i pop in reverse and give it gas it will die out.  when i pop in reverse sometimes in will die right away (before giving any gas) and 1 time out of 100 when i pop in reverse it will operate perfectly fine.   and yes, it operates perfectly dine in normal drive H and L.  any thoughts??   when i called the dealer i got it from they had no idea.

      I have a 2004 KUBOTA RTV 900 DIESEL and I need to replace both front cv axels.I have been online looking at them and there seems to be a lot of different manufactures to choose from. My question is who makes a good aftermarket set of cv axels for this KUBOTA. I have read horror stories of people buying the  cheap Chinese brand only to find out they don't fit or they don't last very long and fail again. I hate to have to spend over $200 a shaft to get OEM from KUBOTA when I'm sure there is a company out there who probably makes it for them or makes comparable to OEM. Thanks for your help.
