I was chillin with some dudes at a charge stop and when we pulled out my board went a few feet and then locked up.
I noticed that one of the motor connectors was I think not fully connected. No idea how that happened I guess I neglected to screw together the collar that holds it together last time I was messing with it and then maybe I knocked it apart when disconnecting the charger or something?
Anyway I ubered home and a few minutes after I got home I heard a weird sound and there was fucking flame squirting out the ports.
I debated throwing it off the balcony but the flame died down so I took it down the stairs to the parking lot instead:
My working theory is that trying to punch it with one motor partly or fully disconnected popped something in the ESC creating a short that kept heating up for the next hour.
So I’m a very unpopular person in my building right now. I didn’t realize while I was disecting this board in the parking lot my neighbors were in the hallway debating whether to call the fire department.
It really stunk up the place.
I had a loose motor phase wire, my 6.6 dual crapped out, when i got home there was a short in one channel of the esc, had i kept pushing it im sure something woulda blown. Long story short, loose phase wire cause problem, not sure why.
OK,this is how i will tell if my gf spies on this site,if so she will loose her mind. I had to build a fucking bunker to get her off my ass. I have welding blankets,smoke alarms and powder fire bombs all over my garage,. I am aware this may not stop my massive battery from catching fire ,but i had to do something to get her off my ass
Question im assuming any extinguisher you can carry on a ride is not got a chance in hell of stoping a fire? I want to say right now if my board ever burns on the side of the road,IM CRYING LIKE A BITCH, because 1 fucking fire and ill never be able to ride a Esk8 again AND have the same GF.if it ever burns in my garage ill never live it down.
Theres special lithium extinguishers. Generally they dont work that well tho xD
Down in the lab at work, we have a big box with special granulates, if something catches fire or vents we toss it in this big box and quickly close the lid to suffocate any fire.
If its a bigger fire, we have escape routes (our battery setups are usually comprised of 2k+ cells) for our trolleys where the battery is situated, rolling it outside to not burn down the office while wearing a gasmask is the primary goal.
Allegedly the most effective way to deal with lion fires are cooling the cells down. preventing thermal runaway. Practically this pretty much means submerging it all in water.
To get back to topic, @GnomeMeansNo, be mindful of the gases released during an actual battery fire. They’re extremly toxic and very bad for you. Electronics fire isn’t that great for you either, but proabably not as bad.
Thank you, i was going to suspend sand in paper bag above a brick enclosure my boards would sit in . My thinkig was the thin paper would allow the sand to flow and fill the enclosure and if not suffocate the fire,at least encapsulate it and perhaps cool it?
I am so far out of my depth,so excuse my ignorance. Is there a granular product better than sand? I know i cant smother a lithium fire,but would not 6" of sand or more contain the flames,and hopefully prevent spred if not smoke and fumes? The box idea is more attarctive to my current encapsulation with 3 layers of welding blankets and powder balls in side,its clumsy i dont like it .
Yeah when I was trying to get clearance to use them in a university lab that was the solution we came to. Very small vape cells so it’s easy to have nearly 1000x the cell volume in water sitting right next to the test
Glad no other property was damaged and you are safe duder.
Out of curiosity how old was your stormcore? A lot of 60d+ and 100dx seem to be very questionable quality control wise circa spring 2022 till January 2023 ish.
This is very anecdotal but there certainly was an uptick of burned stormcores being posted around.
