How To Make Emergency Charger Using Car Batteries

I feel mocked. No, not at all. Yeah, I'm mocked. You're an emergency guy. It's good. If there's ever a zombie apocalypse or anything, people are coming to you. Yeah. It's fine. If they can get over the fence. We're going to talk a little bit about emergency power. Part of the reason I am an emergency person is because my mom lives in hurricane country, my aunt's been through a couple of fires, I got friends in Southern California that occasionally wake up and see walls a 70 foot high flame outside their homes. --And earthquakes. And earthquakes.



And hey, if you ever lived up in the mountains and you suddenly realize that you have no power, you may think you yourself, gosh, I wish I had a big battery. And basically, what we're going to create is a big battery. I love this. This is one of Anchors 12,000 milliamp-hour batteries. It's great. It's awesome. There's one of these in my bag at all times now. I can charge up to three devices simultaneously.

It'll deliver a max of two amps, which is awesome like for a day or two, or for a few days traveling. What we're going to do here is we're going to take a full size group 24, group 27 battery, we're going to put it in an enclosure, we're going to fuse it so we don't light ourselves on fire. We're going to add in some standard cigar lighter sockets or 12 volt power sockets to it so we can plug things into it.

And we might even attach some kind of an inverter on top. And we're going to talk about a way to keep it charged. Because if you don't keep your emergency battery charged, you're going to feel really stupid in the emergency where you put something into it and you're like, huh, there's no battery life. It's preparation, not panic, right? Yeah. That sounds like a saying. I like that. All right, let's do it. All right.

So while Michael's finding a wrench to fit this battery terminal, these are really cool. These are like Marine battery terminals. Sometimes if the bolt goes this way they call them, like military battery terminals. Tactical battery terminals. But the idea is that you use one bolt to tighten the lead terminal-- and use led, not zinc-- led terminal on the battery, and the other terminal to attach your stuff. In this case, one size is 5/16, one sizes 3/8.

And we're going to attach all of our various devices with ring terminals to the top here. Assuming, of course, that actually works. There we go. Thanks, man. Remember kids, never ever drop a wrench between the positive and negative terminals. You get the exciting moment, and possibly a semi permanently welded wrench. If you're really screwed up, you'll manage to light the battery on fire. I should probably explain what's going on here.

This is a car battery. This is great, because it was in my garage and I can use it. Car battery, though, are not deep cycle batteries. Car batteries-- there's lead plates inside a battery. Car batteries are ones-- their spongy. There's a ton of surface area. And that massive amount of surface area is what gives you the ability to pull all that ampers. The cold crank in amps out of the battery. What we want is big, thick, deep led cells-- or plates inside the battery, pardon me, that are comfortable with discharging and recharging, and discharging and recharging. But this will be fine for our case. It's just, it won't last as long. Exactly. Not as many cycles. Yeah.

So if the zombie apocalypse comes, scrounge some proper deep cycle batteries. Or better yet, like six volt golf cart batteries. Trojans are really nice. But if you're looking for something to get you through a couple days after storm, keep the cell phones charged, this will do fine. And this will keep you from using the batteries inside your car. Because there's nothing more embarrassing than not being able to leave the ravaged, flooded area because you can't start your car. So the super-cool guy version of this project is to get your ham radio enthusiast on. Use Andersons's power pull system. This is like a power works adaptor that's pre-wired.

It comes with 45 amp fuses inside of here. It seems easier, actually. It's really amazing. It's a little expensive to get into, right, because my crimper for these connections are $40. This ready-to PS4 connect-- it's really cool, right, because you can put power in on one side. There we do. So now, you know, I should be able to draw power off of the other three of these. They do some amazing stuff. Interesting. Yeah.

West Mountain Radio-- I think it is, they do these incredible power boxes with a rig-runner units, which are all pre-wired and can manage sort of like charging. And there's a lot options here. We're going to keep it simple though with stuff you can find at your local hardware store or local automotive store. So with that in mind, let me pull the cool-guy stuff out of the way. So we're going to connect these two some cable I'm going to use overkill cable music can gates 12 gauge should be fine for this distance and actually, before we do that, I should grab this.

Fuse, fuse! So we're going to fuse both of these, because I've been hanging around the Ham Radio Shop looking at Anderson power pole connectors, and they double fuse everything. So to keep this super simple, right, we've got our 12 gage power sockets there. I'm going to crimp a 3/8 inch ring connector on here. Hopefully without crimping my fingers. Then you'll become part of the circuit.

You know, you can only do that so many times. And good, used the right size. While I'm thinking about crimping, and being crushed, and manged, and mabeled-- mango? Mango. Hey, how do you avoid dying in a traffic accidents? Seat belt. Good. Click it, or ticket, people. The NHTSA-- National Highway Traffic Safety Administration. Did I get that right? Something like that. Something like that. In any case, we're the people who basically want you to not die in a traffic accident. This holiday, and every single day, and every single minute of the year.

It only takes like three seconds. Less than that. Yeah, if you look at traffic fatalities-- traffic accident fatalities-- with and without belts is like the difference between being dead and being not dead. So don't be dead, because we want you watching the show, we want you making things, we want you having fun. Because how can you die trying if you're already dead? Die trying, wear a seat belt. There you have it. We finished adding our quick connects and hooked up the ring connectors to the battery. Then came the holes.

Fortunately, the battery case is made of plastic, which makes drilling it super easy. We screwed in our power sockets and-- Time for testing. We use standard-- bought at my truck stop power inverter. 12 volts in, 120 volts out inverter. Check light. Yes! Yes! Cool. Now we just got to figure out where the battery tender is. Keep the battery charged up without destroying it, we put on a battery tender junior. It's a little tiny wall socket, it runs 750 milliamps charging. And it fits quite nicely under the hood with the rest of our wiring. One last thing before we go, you want to make sure you secure your battery.

And hopefully I'll actually do it right, because I always the trouble with these-- oh, that's why it wasn't working. So this is the battery strap that comes with the case. And the trick with these is to actually a, make sure this thing's clicked together properly. And the point of this, right, is because if somebody picks your battery up and tips this thing upside, it's like 25, 50 pounds of battery inside of here, which is going to come spilling off and tearing all of your careful wiring out.

And what you want to do is make sure you actually have this attached. So that's in it's teeth. And that's going to hold our thing. Is it still working?

GoPro Battery Test

welcome back to another big Irish production video now in light of the new gopro hero4 camera having just come out we decided to do a tests testing for different types of GoPro battery brands. so here goes now for this first test all of the different battery brands were tested at 4k resolution at 24 fps and all of the tests done. GoPro Battery Test  in this video were shot at a flat color ISO 1600 low sharpness protune turned on and white balance at neutral even though I did do some color grading to these shots all right that concludes our 4k test with new mode coming in first smart tree coming in second GoPro coming in third and wasabi coming in . last let's do some more tests only this time we're going to have the GoPro at 120fps yamoa and wasabi batteries both at 1080 at 60 frames per second and the smart tree battery at 2.7 K at 48 frames per second and these last tests are just to give you a rough estimate of how long you can expect the batteries to last at these...
