Man it saved ass too. I was stuck no cell service in the foothills . Ithanks .... I am peacefully eating pizza at home saved me hours after another day at work..
I wonder if you hook it up to the battery. And just try to charge the battery from the m. 18 V, but I'm not sure how well AM18 battery will charge a 12 V battery. So you have to leave it on there for a bit, but to avoid frying the system. I disconnect the battery from the car
I just jump started my car with 4.0 M18 battery and some scrap 14 gauge house wire. It worked…. In the future I’ll disconnect the battery first and let the m18 charge the battery and the reconnect to avoid damaging any electronics. But it did start right up connecting directly to the battery…. IDK…
I would “believe” the 12 volt battery would charge off the 18 volts the Milwaukee is throwing at it very very hardcore like ripping that voltage down hard. It’s almost like the battery was refusing the charge. But that does show you can’t count on the car battery to pull the voltage drop to protect your electronics.
@@L8R-HP these battery packs consist of five banks each being either a singular high-amp rated 18650, double or even triple in parallel. Initial voltage of each bank is set at 3.7 volt while the ultimate voltage is at 4.2. A fully charged M18 battery has a total output of 21 volts, hence 4.2 volts multiplied by 5 whereas a discharged M18 battery only has an output of 18.5 volts. 21 volts is *alot* to feed to a regular vehicle. If it’s really an emergency, I would rather disconnect the battery and charge it separately using the M18 battery than connecting it to my car, potentially frying the electronics of it. Bear in mind that M18 batteries aren’t innocent. They are designed to be used by a power tool and are capable of outputting more than 30 amps or greater. That’s 30 times 21 which makes it a total of 630 watts. That’s enough to melt a foot long half inch steel wire.
An older car would be fine, the newer electronics will fault out with anything over 16 volts of the ford's. You can do this on a brand new silverado and it'll work. The electronics on the ford will be fine once you give it a regular 12-15 volt signal
@@L8R-HP I would agree. The video would have been good to test that idea. In fact, I used a M18 to jumpstart my car today. According to what I found the starter systems are typically rated to withstand around 30v input +\- and a normal charger does around 14-15v. So if everything is working as expected a M18 should work, and if you can’t start immediately then perhaps leave it for a few seconds. I wouldn’t want to test this much longer than a few seconds, a minute at most. I would also not recommend this as there is little or no safety measures. So this is only a solution if you know what you are doing and you are in a jam and need a quick solution.
Milwaukee battery is supposed to be used when the car battery is too weak to crank the engine. Connecting the Milwaukee battery to the car battery for a few minutes will slowly charge the car battery, since the voltage is greater (18v), but the voltage will drop down to a safe level since there is a large amount of current flowing to your car battery, which the Milwaukee is struggling to provide. If you have enough charge to restart your car, and you connect a 18v battery to your car battery, then of fucking course the voltage will be higher than 12v.
The power tool batteries aint boosters, they actually trickle charge so u have to wait for a min then it'll work. also the battery charge indicator light will lose a bar wen its working🤙🤙
I literally just did this on my dual battery setup on my 6.7 diesel cummins and started in 5 seconds wouldn't try it regularly but in a pinch it worked. 6.0 m18 also have had to do it with dewalt batteries on a work van v8
Wouldn’t help, then it would struggle to pull power from the battery and he is already requesting over a kilowatt of power out of it. (Since the main battery is dead all the power will be needed out of that battery)
I've been seeing people jump start their vehicles with M18 batteries a lot lately. So I took it a step further. Hope you don't mind me posting, but here is my home built M18 jump starter, but it also has protection circuitry. th-cam.com/video/OS_mCICJeC0/w-d-xo.html
Me too. A 12v 35AH SLA mobility scooter battery is far better than any jump pack made. Two batteries in parallel with 4ga jumper wire are even better. When it's ready to be charged you can use just about any modern car battery charger made. So simple it's silly.
You cannot crank a cordless drill with batteries. At least 250A is required during cranking. If your battery is not dead, you can charge it first and then crank it.

2 days ago I jumped my P.O.S. 2014 dps6 focus with a 20v lithium HART battery!! Connected for 15 seconds or so and started right up..
If the car is manual, you can start it with the little battery by pushing the car on second gear.

Would coat hanger wire work?
Hope Milwaukee comes out with an M18 jump starter. They ought to pay you for testing lol
😂😅
Just did it with my m18 and it started just fine with some 14 gauge wire..
Cool real world test
It’s a powerful 20 volt battery. It might fry the electronics.
18v and it didn’t fry anything.

could you charge the battery enough to start itself?
Yea prob

Very interesting Video.
The newer ford electronics wig out with too much voltage. You can unhook the battery and charge it a minute with the m18

Haha thanks captain obvi 😅

Great test.
Car computer and electronic don’t like anything over 14v.
Yes
Thanks you answered my question.

Must be the car blocking work on 2014 honda pilot 18v 3ah and scrap house wire
Was the small battery 18v or 12 v?
I would like to see a resistor added to see if the voltage is lower if it could start the vehicle.
Wouldn’t help, then it would struggle to pull power from the battery and he is already requesting over a kilowatt of power out of it. (Since the main battery is dead all the power will be needed out of that battery)
Probably broke the parking paw knowing this video is a year old could have figured it out by now lol

That’s gotta be terrible for the Milwaukee battery too, so I would NOT even try this with the 8.0 or 12.0 those things are expensive as hell
All good
Expensive, however, they can much better hadle the output.
Leave the vehicle battery connected and you'll have much greater success.
I used my Milwaukee batteries to boost my vehicle
I’ve started them with a lawn mower battery

Word
You can't crank a drill?
all about amps. not voltage.
Yes
I wonder volt regulator 18v to regulator to 12v? I’m not expert. Just an i an ideas 💡 my wife call me baby Einstein 😎
this video was 10 minutes of random rambling and 1.5 minutes of value, trash production man, get to the point
I know right. Why would you even waste your time on this
I thought I was the only one that noticed this😁
