Sharing how i went about the behind the seat dual battery installation on my 2015 Mitsubishi MQ Triton. Had a lot of fun doing this installation. #dualbatteries #mitsubishi #redarc #bcdc1225d
this is the best video I have seen on a dual battery setup, thank you for actually showing everyone, every single part of the system. you've answered so many of the questions that I had.
Hey mate. Great video! I’ve just bought a 2015 MQ and just wondering if you know if they have a smart alternator in them? Did you have to run a wire from your ignition for the DCDC charger?
hey mate awesome video, I am wondering about how everything is earthed. Can I earth my redarc and second battery to the cab or do I need a wire to the starter battery? cheers
Hi mate, i ran a twin red and black from the start battery but you can earth to the chassis no problem just make sure you have a good metal on metal connection. Cheers shaino
Awesome video mate. Got a question regarding terminal connection. If I want to use a vsr instead of a dc charger can I connect the input from starter battery and output to accessories on the same terminal like piggy backing? Will that cause any problems regarding charging or output. Cheers
Thanks ryan! You definitely want your accessories to come from the positive on your second battery that way the connection from the isolator to the second battery will be fused and your 12v items will be protected. Depending on the vsr it will monitor the state of the second battery also.
Is there a need to run an ignition source wire from your charger to your fuse box? Obviously so that your charger isn't draining your Crank battery when vehicle is not running. As far as I understand MQ doesn't have a smart alternator and so is no need for this ignition wire? I'm not sure though lots of different info out there thought would ask if you knew, cheers!
@@southernstarreview righto. Im my vision is to have the second battery in the tub and dc-dc charger. Then want a fridge and charging dock sort of idea in the cab is that a possibility
Yeah man thats the best thing about doing it yourself you can set it up the way you want! If you put the second battery in the tub i would run 6b&s cable to avoid voltage drop between start batt and charger.
Gday Anthony, on the right hand side behind the seat if you take the moulding out on the side, there is a factory grommet that you can run the cabling through. Then just go straight down to the chassis rail and along to the rear of the tray, easy as mate!
Thanks janine! I just used standard liquid nails you could also use sikaflex 118 construction adhesive. Just make sure your screws dont go all through the wood. Cheers shain
Did you remove the top tether point? Does the battery rub on back of seat? I'm trying to fit same arrangement but battery appears to be in contact with the seat.
Gday dean i didn’t remove the tether and the battery does contact the back of the seat but it still locks in. You could cut a hole out of the battery box to allow the tether a bit more clearance. Hope this helps cheers shain
Hey mate, quick question, do you know if there is another way into the rear tray to prevent drilling? Is there a factory hole/grommet that can be utilised? Thanks
Hi Matt, not that i am aware of. Its pretty easy to drill it out though just use a stepping drill bit and make sure you spray the bare metal with some zinc paint.
