Use an isolator, but not an electronic one unless your father in law owns an isolator factory and gives them to you for free. A standard Ford starter solenoid will do exactly the same thing and will outlast an isolator 20 to 1.

Not exactly, no. Two completely different devices that don't function the same in virtually any way.

Don't wanna be "that guy", but a second battery doesn't increase the pitiful capacity of the factory inverter which drives the plug. At only 150 watts you are limited to charging your iPad, or possibl

Hmm...so I could run a sawzall off the 120 plug with this? I tried the other day and got no power...

Not sure what inverter you guys are referring to, I don't have it though. Can't run 110 off my truck. The hair dryer/microwave comment was a joke ha-ha.

You wont be able to run a microwave by the way, you are going to burn the wires out unless it is on a dedicated wire to a dedicated inverter.

 

 

 

You probably tripped the breaker AND the fuse, I did that when I made the mistake trying to run a mini vacuum.

I didn't burn it out. Still works. Just wanted to try it.

No, the 2nd battery tray is unused on the 1500. There are dual battery options but are only available for the 2500 and up. It is a mystery why GM includes the tray on the 1500.

I guessed it was a structural piece?

Here is the start of my second battery setup. All I need now is the cables and thats happening this weekend. Im using a Isolator with remote, Safety hub fuse block, post fuses and 2/0 Cable. Everything but the cable is from Blue Sea Systems. The system will be used for a few things including winch, light bars, and when off grid camping with the RV. The battery im using was one I had around at some point it will get changed to a new one with studs so im setting my cables up for that. For now im using post to stud adaptors to make it work. I have some deep cycle batteries that would be great to use but with out cutting the hold down bracket it wont work. Here are some Pictures.

Excuse my ignorance, but what would be the purpose of having a 2nd battery?

I am married to a rocket scientist that is related to Tim the Toolman. He installed a second battery with an inverter on my old Chevy Astro van. He did isolate it so that you had to switch it to use it for the main engine. It was able to do amazing things. If I had a dead battery, I flipped that switch and started my van. My sons could use the inverter to run their computer games or watch a DVD on our mini TV. (Only allowed on big trips) I did use a blow dryer to dry my hair and use my hot curlers on camping trips. If the battery died on our RV, He created a umbilical cable so thatwe could jumper it to the RV and use the second battery. ( but remember to pull the fuse on the RV battery to make sure it didn't drain the secondary battery). The battery was underneath, so it wasn't available to use to jump someone else's car. But when we install the second battery on my new truck, we will be able to jump another battery. Hubby will set it up the same way as my old vehicle. We are just trying to figure out where to put the inverter in my DC. We were thinking under the passenger seat. Anyone tried this yet???? We are a bit concerned about air flow and it overheating in that location.

The isolator does what yours does without flipping a switch. It is an automatic device that isolates the second battery when the ignition is off. However, when the vehicle is on the alternator will charge both batteries, allowing for a true automated process. You would still run your invertor off of the second battery, and any device you needed to run. As for the mounting under the seat, I would go by how hot the invertor gets as to whether or not I would install it there. A small one would definitely be no problem.

It's been a few years since this post started any new kit available I am thinking about adding a second battery for my sound system

I've been toying with idea myself. I would like to be able to plug in a power tool every now and then when I am working somewhere where a power source isn't available.

I did my own storage set up and would like to add a inverter off a second battery.

The storage set up pictured below I wish I would have done years ago. I love it.

I just ordered the parts for installing a second battery if anyone needs the list. I already had the tray so that eliminated 5 of the 12 parts needed including the battery.

      I have thought an EV might have some practical value in extending the life of the ICE members of ones fleet. Now....I'm convinced of it. I've been letting my better half access Raven (Mitsubishi Mirage) for her needs while Dizzy has been in the shop. Being the fuel freak I am and given the fact Raven is capable of over 60 mpg in clean air on a warm day I was taken back by the wife's ability to take a car that had used a half a tank of gas that to that point had returned a value of 57 mpg and return in with a decimating 51 mpg for that same tank in that same day in a 15 mile round trip of short hop errands and a stop in the drive through at Micky D's.  😱   Trust me on this. It would take the remainder of that tank driven on the highway to return that tank to just 54 mpg. This is not a Mitsubishi issue. This is an ICE issue that is magnified in vehicles capable of such high fuel economy values. On a percentage basis your 1500 does the same thing. Short hopping an ICE consumes a good deal more fuel and in doing so provides zero additional useable outputs. That entire volume of fuel is wasted in diluting the cylinder walls oil films, creating crankcase moisture and acid content and the resultant wear.    Enter the SLATE. All of that is avoided and the ICE's advantage in range and made useful at reduced wear for your ICE!   Kind'a cool.

      Back in the day people would buy cars based on performance. The charger posted does 0-60 in 3.3 seconds. And it’s fully loaded.  It has a decent warranty and will fit most anyone’s needs. Remember the original Hemi? 90 day warranty. 25K mini truck or that car? I’d go with the car. It wouldn’t fit my perimeter. If I could just talk my wife out of her Genesis. It would be perfect for her.

      Let's pivot this back. Someone said they wanted pictures.   Even better, there's already video. Pre-prod prototypes are already on the road and they're letting the press drive them.   JerryRigEverything did a good review. I really enjoy his content and EV adventures, so I was thrilled when he had the chance to review a Slate:

      The Charger EV was stillborn. Wrong car at the wrong price for Dodge's intended audience. Now at a good price with fire-sale discounts, and still not selling, it's still very much the wrong car. Again, Dodge's intended audience. I believe a lot of Stellantis' EV blunders were all under Tavares' regime at Stellantis...the board convinced him to move on. Neat car, just wasn't received on the level that would sustain mass production.   Dodge is headed in a better direction for its core business. I didn't think there was anything left to get excited about re: the Durango after its 15 year run, but they're just now releasing a 392 version that should price out in the low 40's. Nicely done. I'm not sure I would touch anything Stellantis makes with a 10' pole these days, but the Durango is still mostly parts designed like 3 parent companies ago so maybe it's still OK?
