Yes, 2 AWG will suffice. All wires in an electrical system should be fused to protect from shorts, and thus should be placed as close to the power source/distributer as possible. Even if the device you’re hooking up has a built in fuse, that won’t protect from shorts in the wire delivering the...

Glad it all looks right. I’ve been meaning to put the formula I’m using in the calculator’s description for educational purposes but I haven’t gotten around to it yet.

What all are you planning on powering with this setup? A 700W inverter and a couple of 12V outlets is technically do-able with that Genesis setup, but with around 30Ah of useable power, it’s not going to run stuff for very long. I agree with everything @RagnarKon said. I added that tooltip to...

How many miles is this based on? These numbers are useless without the full picture.

All depends on wire length 😉 https://cr117.github.io/calculators/dc-wire-sizing/?volts=12&amps=5&distance=40&wattsMode=1

Looks like it fluctuates between 3A and 1A:

Battery isolators, like the one you linked, don't work all that well with smart alternators like the ones we have in our Broncos. The voltage fluctuates based on a number of variables and isn't designed for charging an additional battery in parallel. You'll need a DC-DC charger to charge and...

Survived another trip to IKEA.

Ordered mine Monday night using my points and with the 4th of July sale discount, just arrived today (Wednesday). I was not expecting it to take less than 2 days to deliver considering all the issues other people were posting about earlier in this thread. Now I need to put it all together, add a...

Definitely. I can't trust online retailers anymore for "good deals" on wires, terminals, and other electrical components unless it's from a reputable company. In-person shopping for these things is better because you can verify type of metal used and its thickness. Marine supply shops are where...

I'm in the same boat. I don't code as much as I used to, but I still manage projects that I built with React and Vue. When I'm just trying to build a dumb proof of concept, like this, I tend to revert back to old habits because I know it just works. Only if I can tie it to your cell number.

Don’t judge 😆 it was the quickest/easiest way to build something this simple.

As long as they’re the right gauge and are good quality (decent insulation, not copper clad aluminum).

I got tired of looking up wire sizing charts for my recent projects so I made this little calculator that I can pull up on my phone to quickly figure out what I need to use (screenshot below). Just wanted to share in case someone else finds this useful...

No, they're not the cheapest option, but they're built like a tank. We use them for more than just off roading, so it made sense to spend a little more for the longer battery life and waterproof-ness. I have their plug in handset as well, but have found that for driving, reaching up and holding...

It's Rocky Talkie's 5 Watt GMRS radio with along with their cradle that mounts to a ram mount 1" ball setup (some cheap Amazon one I found that mounts to the grab handle bolts).

Finally got a mount for my radio. I'm running a set of Rocky Talkie 5 Watt GMRS radios with along with their cradle that mounts to a ram mount 1" ball setup (some cheap Amazon one I found that mounts to the grab handle bolts). Most of our trips are solo, so the pair of radios we have are...

In most states, you’re only allowed one set of fog lights to be on with your headlights when on the street. I’d wire one set into the factory harness and have the other two sets tied to an aux switch.

Took the family to the beach Daughter wasn’t ready to go back…

No chance the battery lasts for airing up all 4 tires from 15 psi. You’ll be lucky to get two tires done before it dies.
