Tool Battery Car Jump Start?

[@LockyourHubs4WDing]

What's your favorite trick to get a dead 4x4 going again?

[@michaelhansen4x4]

My Falcon EFI V8 had a flat battery and we tried this with a Dewalt 18v 5ah battery. Worked mint. We only left the battery connected for about 30 seconds before we started the engine as we had the same concerns about 18v into the ecu. That was about a year ago and we've never had any bad after effects. Great video cheers!

[@LockyourHubs4WDing]

I was quite surprised how well it worked!

[@michaelhansen4x4]

@@LockyourHubs4WDing yeah us too, it got us out of trouble!

[@cookinggrandma1]

Did it with wires…game changer. Worked like a charm

[@LockyourHubs4WDing]

I was super surprised as well!

[@DIY-ry9so]

Thank you so much for this video! Next time my battery die, I will do it like you did. I will jumpstart my car with a smile on my face.

[@LockyourHubs4WDing]

Glad it helped!

[@peterryan7340]

My wife and kids bought a Schumacher jump starter for me last Christmas and was very sceptical of it's abilities, but having used it on a medium sized Kubota tractor, a 6 year old Holden Colorado and a 6.4 Hemi I am a convert to these.

[@LockyourHubs4WDing]

Those little lithium cells sure can pack a punch!

[@robbyjoeagustin6326]

Thanks for sharing. I just tried to use this approach using Ridgid 18v after I did not start my car for 2 weeks. It worked..

[@LockyourHubs4WDing]

Great to hear!

[@jpbmx2x]

I tried! and it does work! thanks mate!

Brilliant.. and the work with the forks - next level!

[@LockyourHubs4WDing]

Some acuse me of not even knowing where the box to think outside of is located!

[@alexchong213]

I've tried this to test lights on a trailer once and blew all it's bulbs! So no important circuits like memory of all your ECU'S and stereo to worry about? I'm guessing the car battery being flat was dragging your voltage down which helped.

[@LockyourHubs4WDing]

Where you just feeding the trailer circuit the 20 or so volts from the battery pack?

[@MrShanilicious]

THIS is QUALITY content!

[@LockyourHubs4WDing]

Thanks!

[@charlschuck6]

I wonder for how long can you keep the wire / connector connected to that 20v bat and what would happen if you lets say leave connected for for instead of 1min , it’s stay connected for 5/10 mins and then try to start up will it start or just drain the 20v and act like a charger but not a jump booster battery ? What’s the minimum AH Or brand recommendations will a 1.5AH bat 20v make the trick ? I guess it also depends on the vehicle size isn’t it the more or less possibility I’ll turn on ?

[@dannyalarcon3484]

You should have cable that has aligator clip on the other end so you can detach it easily,you shouldn't attched for long period to avoid damage from your alternator

[@LockyourHubs4WDing]

That's a great suggestion, though I was determined to pull this off with just what I had in my camping setup.

Aluminium foldable camp chairs also work. Thats if you have no jumper leads. Just needs lots people to do it. (Yes it’s true)

[@LockyourHubs4WDing]

I've seen a picture using 2 steel bodied assault rifles to jump start a car!

[@FoookYourfeelings]

Sounds great....is there any chance of frying the circuit? Car being 13.5 a and this 18v? It's just a question as i have no idea.... thanks

[@LockyourHubs4WDing]

This one's an old school diesel, no real electronics to speak of.

[@lastknownlocation8760]

Kirchhoff's voltage law (2nd Law) states that in any complete loop within a circuit, the sum of all voltages across components which supply electrical energy (such as cells or generators) must equal the sum of all voltages across the other components in the same loop.

[@LockyourHubs4WDing]

Thanks for the clarification!

Good video buddy enjoy watching the video ...........cheers

[@LockyourHubs4WDing]

I jumped a falcon with a 5000mah 3 cell lipo from my rc car.

[@LockyourHubs4WDing]

Nice! Did it work ok?

[@jonathonrobinson6638]

@@LockyourHubs4WDing surprisingly well. Had to cut the plug off the lipo and just zip tied the wires onto the battery while I started it.

[@andersonnettleship845]

Great video, my concern is will I ruin my expensive Makita battery by using it to jumpstart a vehicle? And I doubt that it would work on a 5.9L Cummins Diesel in my Dodge Ram 2500 but it has a standard transmission so I’d just push start it.

[@LockyourHubs4WDing]

That was a 4.2 diesel, seemed to work ok. Though the big 5.9 might push the friendship! PS I'm still using that battery.

[@ToolsAndStuffOFFICIAL]

@@LockyourHubs4WDing Kevin sent me the link for your vid. Well done. I used to know a guy who never even had a battery in his wagon and would always just start it with one of his tool batteries the tight arse.

[@LockyourHubs4WDing]

@@ToolsAndStuffOFFICIAL haha, some people are unbelievable.

[@Ess_Chalk]

It always makes me nervous when I see engines started with the 18V battery still connected. The internals of the battery pack are not made for high amp draw, although it is (ideally) such a short burst that the risk of fire should be very low. Still, it's not something that I would risk with a $200 DeWalt battery unless I really had to. Nice work on the forks though, it's very bush mechanic 😁 Since it will provide 16-17V depending on the battery pack capacity but for a short duration, I wonder if there's any gassing?

[@LockyourHubs4WDing]

I've not heard of any issue with outgassing of the cells. And I was determined to only use the battery and what was in the camping box, so forks it was!

[@grounded7362]

What mods would be needed to use the 18v battery to jump start a newer motorcycle?

[@LockyourHubs4WDing]

The the motorcycles electrics can handle the near 20v output from the tool battery, nothing.

[@grounded7362]

@@LockyourHubs4WDing Thanks 👍

[@ElkayLive]

Had to do this today haha.

[@LockyourHubs4WDing]

Works like a charm!

[@abdalqadr1]

Does it work if the voltage more than 15volt or may damage engine computer❤❤

[@LockyourHubs4WDing]

It will depend on the design of the ECU in the car though this LandCruiser doesn't actually have an ECU so there's nothing to damage!

[@MiniLuv-1984]

Very good! Loved the analysis. This got three neurones going - the other four are in lock down :) First, if the starting battery is good but really flat, then it's not likely anything connected in the vehicle will see the 18V (20V if its fully charged) from the tool battery. Most of the voltage drop will occur inside the 18V pack if the protection circuits for limiting current/temperature of the cells is working in the tool battery. At worst the terminals will see around 15-16V for a brief period then drop to normal charging voltage pretty quickly I expect. In any case, it's probably a good idea to disconnect the battery from the vehicle before you do this. Since I already carry tool batteries, I think I might add 15m of 24AWG twin core with crocodile clips and tabs at either end giving me a total of 30m cable or around 0.5R to my arsenal, or longer if its heavier gauge speaker wire (yep, cheap speaker wire)...aluminium wire even better! By the way, did the Makita charge up ok after this?

[@LockyourHubs4WDing]

You're right, it depends on the state of charge of the main battery will determine what the resultant voltage will be (and the current heading from the tool battery to the car battery) Different brand/capacity tool batteries will have different current limiting abilities and low voltage protection etc. You'll be happy to hear the Makita battery charged up fine and lives to fight on another day.

[@MiniLuv-1984]

@@LockyourHubs4WDing I reckon you are on a winner there. Who wants to shell out another $100 to have yet another thng in the vehicle that, chances are you will only ever use once and it too may be dead when you need it most (Murphy Guaranteed Outcome).

[@MarkSpohr]

Would have been interesting to measure the battery voltage while jumping. Probably not more than 12v

[@johnchris3655]

That realy works??

[@LockyourHubs4WDing]

Certainly does!

[@ES-te3io]

To getting shot is there a risk of getting shocked doing this

[@LockyourHubs4WDing]

Not at 18v.

No wire available? I know there are supply chain issues but what a waste of two perfectly good forks.

[@me217]

i'd be very surprised if you actually got 18v to anything important if the main vehicle battery is so low.

[@LockyourHubs4WDing]

You're probably right, it'll be heavily dependent on the state of charge in the main battery, also the rate of charge will be effected as well.

[@DeeegerD]

@@LockyourHubs4WDing They don't produce enough current or have enough capacity. If you can get it to work you will cook your expensive battery. Basic electronics.

[@LockyourHubs4WDing]

Depends on how depleted the start battery is.

[@DeeegerD]

@@LockyourHubs4WDing If it's depleted enough that your vehicle won't start it's going to draw too much current. Fir a 4 cylinder it's going to be about 125 amps for an 8 over 200 amps. Charging the battery without current regulation will heat your power tool battery and ruin it. It simply isn't designed for that load.

[@LockyourHubs4WDing]

@@DeeegerD tool batteries have overload protection, and I'm not saying this is an ideal solution. Though, much better than being stranded in a remote desert somewhere.
