Looks like a pretty good burst rate 🤣

fpv may finally be the thing that makes me buy house insurance. Thanks for the great video bro!

"im pushing 9 amps into it *Currently*" you totally missed a perfectly good pun opportunity!

Holy crap, this just shows how much power is in those little things.🌪💥🔥

You see a fireball, I see a last-second rocket booster Do the rules say the drone has to be operating when you cross the finish line?

that was EPIC! Great job Nurc. We all needed to be reminded of this eminent danger.

Dammit man I never thought that things could get so heated up Thanks

Man, this kind of videos are good reminder for me to store my lipo safely.

I love how you captured the usual project start-up issue's. I think most of my own builds are usually 50% of the time actually doing something and the other 50% spent looking for the thing I just had in my hand 3 freakin mins ago 😩or searching for very specific crap inside heaps of generic unsorted crap that somehow automagically keeps accumulating in like 12 different locations around my house.

That smoke was like, don't breath unless you are Jessica Jones! This is something i don't wish to anyone to experience in his life, LIPO fires are nasty. Enjoy the rest of your week and safe balance charging!

Holy crap, I knew flames come out but I had no idea they came out with such force, or that go that distance. WOW. Thank you for this.

That was insanely amazingly awesome knowledgeable information to be had. Thanks Nurk! 🙌👍

I just got my first lipo, ill keep this in mind, thx :)

Excellent music choice my friend! Epic

Thanks for the demo. I always wondered how much they went up in flames. Now I know why lipo fires are such a safety issue.

Thanks for posting! ! It's just as important to charge safely as it is to fly that way! !! There's so many horror stories of the lack of respect of these Lipos that we depend on! !

Curiously missing, info on how to extinguish lipo fire. Sadly not every charging station is situated for burn to the ground. Unplug first then smother, I keep and have used a large beach towel folded a couple of times to smother it out. Don't use water.

Wow that was impressive.

This is why I charge my lipos on concrete paving, outside. I don't like leaving fully charged lipos in the house when I'm out. I usually keep my lipos at storage charge, in a vented ammo box, in a fireplace! Massive overkill, but shit happens and I like my house ;o)

It will be cool to see how liposafe bags will actually deal with a such fire.

Awesome informative video. Going to weld a metal box to charge my batteries in today. I charge in the house. I always balance charge and never over charge. Even though I do things right I can't take a risk in the house. That flame was way to violent to take any chances

The footage you got of the flames was great.

I never over charge, always balance charge! But WOW!!! Ive never seen one go up like that before!!! Looked just like a firwork!! Quite scary! Thanks for the lesson n ya risk taking to show others! Hopefully you saved a few houses and lives with this!👍

I had one do that crashing onto a rocky rail road tracks. It made me think about what I fly around.

Fark ! (runs to store every LiPo into the garage) phew !

4:45 I thought it's a Nurk's head :).... bit it's just a mic...... thank you, Nurk! useful for all of us.

That big ass explosion happened after just 10m of charging and you only have like 10-15sec of smoke before it pops.. really scary shit, always be safe!

That flame was small compare to the Lipo fires I have put out Racing RC Car Onroad/Oval I the US. Fire from the table to the roof. And there was also no smoke sow no warning at all.

Yikes! I had a fire in my room because of a lipo that i converted it from a 3s to a 2s because my skyhunter crashed into a tree and by the tim i got it down a cell was at 0.00v. A week after it was done modding i took it off the charger, waled away, and heard a sound. Seonds later my face was glowing orange. Lucky i grabbed my dad and we tackled the fire with a blanket and some water on the red ashes. Lost some good batts in tje fire but now am replacing all the equipment after 3 months of the fire. Just some wall damages too.

I installed a smoke detector right above my charging station, a fire extinguisher by the door on the wall and moved away easily combustable materials from around the charging station. Next I would like to get a 25' hose with a quick adapter so I can hook it up to my bathroom or kitchen sink. I have had two occasions where somehow the batteries got over charged, probably because I was going too fast, but I caught both before the fire balls. 4s was @19v & 3s was @14.8v both were extremely puffed.

Oh crap you got good footage. I did that too off camera and my pack flew up on the roof of my house.

thx for testing this!

I use those little car jumper batteries that turn out to be S3 LiPo batteries. I had one catch fire on me while trying to jump a car. Thankfully I was able to throw it onto the ground before it caught the car on fire. Very exciting!

That is intense, thank you for the reminder. I am heading out to get a larger fire extinguisher. However I do charge on my outside porch and if I am charging larger than a 500 milliamp I put the whole rig in the BB-Q grill. QUESTION; Reading comments,,, others and myself will keep the batteries outside in the fire bags. Do I need to worry that much about a disconnected / storage charged battery? The weather is starting to warm up but we still have freezing temps, do I need to worry about them freezing?

That’s insane, really interesting to see though.

Buy a bat-safe for $50, designed for that specific purpose. Failing that, a saucepan with a lid is pretty much perfect in terms of containment. Get a foam or powder extinguisher too if you don't have one. Fire extinguishers go by the exit. If you have to go IN to a room that's on fire to get to the extinguisher, it's not much use.

*me watching this at the same time as I'm overcharging batteries*🤣

nice fire for winter

Great video on lipos thanks JohnnyDRC

That was good, I approve of the fire.

Had my first lipo burst into this little mushroom cloud, thank god I had just entered the room from flying, hurried to unplug battery while it was hissing, ran outside, tossed it in front yard, and seconds later....Hiroshima. Lol. Learned my lesson. NEVER CHARGED UNATTENDED

Good background music

Ok in this scenario dont over charge your batteries....UNLESS you need some PYRO near Some gates for your crazy balls to the walls pilots to fly thru then we're talking Show time!! ok not really, as a person who HAD a non related fire(a power strip connected to a faulty extension wire caused the fire) in my home which took out the majority of my drone stuff, it is not pretty or funny considering my batteries were only a couple feet away from that fire. i wont even keep my batteries in side the house any more and they are only stored in the fire proof cases outside the house. Nice demo, loved the wife cameo at the beginning!!

The sound that thing made was nuts! Holy crap! Guess I’ll never over charge...

So a couple of thoughts; has anyone considered a battery strap with a micro switch? If the battery puffed it would pull the strap tight enough to trigger the switch and could open a relay in the charger 120vac circuit? Also, as I get into this hobby, how likely is it that other wise well cared for batteries burst into flames just sitting at storage charge or even left for long periods at full charge? And yea I know not to keep LiPos fully charged for more then a day or two.

Cool fireworks!!!

Now try it with a 30,000 mah battery! 😂

So I have 4s 1300mah 40c and it's not hv but I charge them on hv all the time have been doing it for 2 years now havnt had a problem at all why is that?????

i have a 7.4v 2000mah charger, how much time should i balance charge a 2600mah lipo? there is a red dot in the charger, but it doesnt disappear after 3 hours

Hahaha I had my earphones in whilst watching this, the explosion 💥 scared the crap outta me 😂 Beavis & Butthead “hu hu FIRE 🔥” 😆

Good stuff! At the end you said parallel charge when I think you meant to say balance charge. 😝

Great job !!!

Try to film punctured LiPo explosion in air! Had such thing at last summer. Pity I din't seen the poof by itself though bystanders did :) Although found the crash site fast due to a ton of smoke here.

UP to 4.9V is save?

Will it Blend?

Not enough slow motion in the world, thank you for that. I do wonder how unstable they are just sitting in a padded toolbox container.

That was nuts!

Nice PSA.

That was freakin awesome...

WOW! I mean I always charge to 4.25v but 4.7?!?!?! Crazy guy :P ...that fireball sounded soooo good!! Is that a Zoom recorder? I've got an H4n Pro, freaking LOVE it!

Just adding, because thousands of people will now do it at home: A lipo is no firework. Everything that comes out of a battery during the fire is not healthy. You would not want this on your backyard.

Neighbors called the authorities on him. This is how he ended up on the terrorist watch list.

I wouldn't want to imagine that happening in a small house/apartment!

Would an external temperature sensor prevent this? I assume the sizzling indicates high temperature inside the pack, so the question is whether cutting off the power after it reaches a certain temperature would stop the process soon enough.

I think I'll set up my isdt inside my grill from now on. Thanks for that video bro. I'm scared to death now LOL

Mrs. Nurk! Great! 😁🤘

i threw a 1 cell 600mah into the burn barrel last week. sounded like a M80 exploding

Flaming brill video nurk 😂

Your outro just scared the shit out of me

Great video. I just subbed.😊

What happens if you discharge the battery too much?

Yeah this made me put some lipos at storage voltage im terrified

Great demo and good advice all around. If you want 6s powah buy a 6s battery lol and then overcharge that. Haha. Good stuff man. Hopefully this teaches some guys a lesson before they learn it the hard way 👍👍

5:06 there's a person walking out of the flames

And i am watching this video when i charging my batteries right next to me.. Chills!

MENTAL NOTE: Build concrete battery bunker ASAP

Vanover was probably hoping that the battery would have exploded right before the final gate giving him a rocket propulsion to win the race

Crazzzyyyyyyyyy

With how many c are you charging your batterys

This was a great example of how easily someone could burn thier entire house down with one simple mistake.

Works like solid rocket fuel!!! Fuck man I didn't expect such a flame :-) :-)

I really don't get it. If someone wants more umph from the pack and the motors just up the cell count! You increase the cell count, you increase the voltage. You increase the voltage on the motor leads, you increase the current and thus the overall power. Want to fly longer on the track? Go 6s and accordingly selected rpm/v motors. The higher the voltage, the less the current needed for given power and the more efficient the whole system becomes as losses are more evident in low voltage+high current scenarios than in high voltage-low currents. Leads, mos-fet Rds-on, even D-S on/off times are better on higher voltages. It's just like trying to overfill your car's tank with gas. It will overflow and you will set it on fire eventually. Go goddamn 10s and talk to be from there. Same watts/pack.

looks like a starting rocketengine

You still made it to 5v before problems.

WOW

holy.shit.

You wouldn't want that in your pocket!

That’s some scary shit

Trying this at home :D

My charger is overcharging my lipos to 4.21v :/

and a little bit of fireballs...lol

Epic!

Annnd I've ordered an ammo box, wow :o

Wow

Michael Bay's wet dream :D

In the words of the great Eddie Murphy " That's A Fire!"

Woah

I think I smelled it when I was watching it explode.

Damn!

Great video! Well done! (See what I did there?) 😂
