    I see a LOT of people in the comments saying not to put water on a lithium battery fire because “lithium explodes in water”. Please remember that there is very little actual lithium metal in a li-ion battery. This isn’t your high school physics lab. The correct way to handle a lithium battery fire (if it is safe for you to do so) is to douse it in water until the fire department arrives. This keeps it cooler, slows the spread and can prevent the fire from spreading to the surroundings.

      It might help if, in the future, you explain what actually causes the fire. The fire is caused by a runaway electrical short, inside the battery, and the electrolyte itself is highly flammable. Sure, the lithium "caused" the fire, but only because the dendrites of lithium built up and caused that short. AND that happens FAR more often with cheap, non-name-brand batteries, which is what all those cheap scooters use.

      @@squirrelcovers6340 No. No it won't. Li-Ion batteries generate their own oxygen while burning in thermal runaway. The only way to put that out is to reduce the temperature. So, lots of water. That is why many fire safe boxes for recharging bicycle batteries have water containers in them that rupture under high temperatures and douse the battery with water as quickly as possible.

      Hi hello sir, may I allow to ask a question and please help reply with your expertise on ebike battery. Yesterday when I was paddle my ebike at home with the parking stand mount on the floor, for testing the ebike speed, then suddenly my mother was talking to me, instead of I need to press the hand brake to stop the spining ebike, I turned off the ignition key, THEN I heard a "pop" sound (the motorhub was still in high speed spinning) I don't know the "pop" sound was came from the battery or came from the controller. Sir, may I ask in most of the cases, let say, if a person paddle the ebike halfway through, when the battery still on going supplying the energy into the controller, and the controller still on going supplying the power into the motorhub, and the motorhub still drawing power spinning at fast speed, then he turn off the ignition key OUT OF SUDDEN to cut off the ON GOING power supply intake from the battery, in this case what will happen to my battery? Sir, please help me,
      then I unpluged the ebike power plug from the battery, then I turn on the key ignition to purposely release the electric in the controller, then I plug the ebike power plug into the battery and heard a as usual spark sound.
      My concern now is, how do I know I already wound, injury, or damage my battery or not sir. Hope you understand my question, trillion thanks if you would please reply sir.

    I currently work as a e-bike/e-scooter technician, I deal with dead and defective batteries daily. Here are some things to consider:
    1. A good BMS will save your ass, a shitty one is likely to be the cause of a fire.
    2. Long term vibration can wear out insulators and metals in ways you never expect, one day the whole side of your battery can short out with the frame if the design is crap
    3. If you have a chance, always get a battery with a "smart" BMS, get to know your battery and discover signs of danger before it gets bad.
    4. FFS dont install lights on your own if you dont know what you are doing, so many people fry their electronics because of this.
    5. A bad charger can keep pushing current to a dangerously high voltage cell group because BMS keeps switching the input on and off, every time its switches on it lets a small amount of current through untill it sees that its not okay and shuts it off again. This is a problem with some cheap BMS's.

    • @noobz5056
      @noobz5056 Рік тому +3

      Original poster, you don't need BMS to not catch fire on batteries. With or without, you can't make batteries create fire on its own unless you are hell bent on trying to make fire on the batteries, by using a lighter and fire starter to create fire. I have tried feeding 65V on a 3.7V li-ion cell for hours (No BMS) and it would not catch fire.. Tried this on multiple times with different make/model of the battery (1 or 2 cells in series) with same result. They do run hot though, but no catching of fire. The battery cells did die due to extreme high voltage (current was pretty damn high too). I have built BMS-less battery packs for my scooter multiple times in the past but none of them caught fire on charging. Another big problem you using the BMS is you are gonna get stranded in the middle of the road in cold winter because your ebike battery received a voltage sag and dip hitting below the low voltage limit of the BMS and will shut off your battery.

    • @UltraNyan
      @UltraNyan Рік тому +3

      ​@@noobz5056 like the video said, battery fires are very rare. I have worked with batteries for many years and only had some just get really hot and spew out the electrolyte but never burst into flames like in some videos. One of my coworker on the other hand has worked twice as long as i have and he has had a few fires, one time charging, one time moving the battery discharge wire that cause an internal short and once he accidentally dropped a magnet on exposed side of the battery.
      Also i strongly disagree with the camp that thinks that a BMS is useless crap. I think you should always run a bms, run a bypass on discharge if you use it on euc or skateboard. If you worry so much about getting stranded then have the option to bypass it. If you voltage sag your battery all the time with cold, well then, be ready to say good bye to your cells soon.
      Running a pack without BMS will result in cells going bad 2x sooner, if you think you are running junk cells anyways and dont want to waste money on BMS then you gonna ruin your junk pack in 4x rate cause those cells like to go out of balance faster. Most of the battery related problems are clients who complain about their battery cutting off at 50%, most of the time its a out of balance pack with one group bellow 3V. If they didnt run a BMS the pack would be permanently dead under a year.
      Coming back to noobs wiring their scooters with lights bells and whistles. Often times its the BMS that will keep your scooter internals melting up cause someone somehow decided to short the wires coming from the battery.

    • @UltraNyan
      @UltraNyan Рік тому +1

      @@Chris_Craft777 don't know your exact situation but usually people tend to overload the internal 12 VDC converter of their controller. Usually its designed to just only manage the headlight that comes with the kit. If you go about installing 2 x powerful headlights then you are guaranteed to fry your converter or the whole controller. Best course would be to use a special "light controller" that works with your controller or have a separate fused output from your battery and a buck converter to 12V that runs all your lights. That way you can run lights with the scooter ignition turned off, good for late night picnics.

    • @spcolsson
      @spcolsson Рік тому +2

      I agree with most of your points...untill number 5. What would be bad in that scenario is the bms not the charger. The chargers only job it to supply a constant current constant voltage power source.... its the bms's job to keep that power balanced between the cells. The charger has no way to sense the cell groups and turn on and off depending on them.....

    I have owned an e -bike for almost 2 years. It wasn't the most expensive nor the cheapest but enjoy it! I even find myself riding it to work occasionally! I don't think it's really necessary but when I charge my bike, I like to wait about an hour before connecting the charger to give the battery temperature a chance to equalize with room temperature.
    I also like to plug the bike battery to the charger before plugging the charger to the outlet and STAY ALERT during the charging cycle! Just in case of an event! I may be over cautious but I want to protect my investment!

    My Kalkhoff ebike uses a Bosch motor and battery. For the first time in its 6 year life, the battery management system prevented me from charging it until it had cooled down sufficiently. I had just completed a hard ride. Once the temp dropped the charging commenced. A good example of what you mentioned up front - always use the manufacturer's charger and choose a bike in which the battery has a good battery management system that can provide the data needed, ie, temperature. Thanks for another good vid.

    I always unplug the charger when not in use. There are electronics inside the charger that control how much voltage to feed the batteries and when to turn the charger on and off. These electronics have to recycle or reboot like your phone, cable box, etc. Also, follow the manufacturer’s guidelines. For example, Nanrobot says to connect the scooter first then plug the charger in.

      That place is the largest city in the world right? So there's more of everything. More people, and more of everything people own. Dogs, toasters, radios, shaving razors, what have you. I think that's a definite factor in quantifying all this. Plus I think of the liberal press as usually having a liberal political angle. If it's something people own that's deemed as something that takes a grown man's responsible mindset to deal with, then they tend to be on the bandwagon to restrict it somehow. Look no farther than gas stoves lately, and privately held guns always. Electric batteries are just another dangerous object to be regulated excessively or banned by the nanny state.

The apartments are also often extremely small, therefore an ebike catching fire indoors anywhere in NYC could result in a literal disaster that could kill dozens of people. @@derekjolly3680

    Another important tip to avoid fires is to take good care of your battery. As batteries age, they build up resistance in the form of dendrites that can generate heat while charging and eventually short the cell and lead to thermal runaway. Don’t leave your battery at a high or low state of charge. In a perfect world, you would store at 50%, charge to 80% and discharge back to 50%. Your Battery would last longer than you.

    Yeah you really have a great Public Service going here with your videos very informative! My charging procedure is putting my battery into a fireproof bag inside of a steel can with a tight-fitting lid with three layers of 1000 degree temperature fireproof insulation that is used on stainless steel chimney liners. The three layers equals 3000 degrees protection so that if the battery does decide to short out and start burning the containment will prevent it from catching other things on fire. The insulation is on the bottom of the can and it's on the lid. The lid is held down with a cam Buckle strap around the can so that if they fire does break out the expansion of the gases won't blow the lid off the can then to top it all off I keep it on a cement floor on my patio outside of my house. And I never charge it over night I charge it during the day when I'm up and can monitor it from time to time. I know this is overkill and it couldn't really cost me much of anything at all and it gives me a lot of peace of mind just like insurance it's there when you need it.

    Hi, I watch ur videos almost everyday, I am here to say my neighbours' e bike caught on fire tonight, it's 2:09 am and I am finally back in my house with my own e bike. Not sure what exactly happened, but I think he was charging it and went out with his girlfriend. I was already awake so I tried to wake up my other neighbours and the police told us to leave the area, so I told him not without my e bike, so I took out mine and just looked at the fire while my building manager was asking me a whole bunch of questions about e bike fires. It's a good thing I watch tonnes of videos. The fire department is still here. Thanks again for making good videos :)

    I use a 52V LUNA charger n put my 30Ah triangle batteries in an ammo can when charging, just to contain any fire that might occur. Never had any issues charging, even with "inexpensive" batteries from DH Gate. One caution I do have: Eyeball the wires where they exit the battery for worn or frayed insulation! I found 2 batteries with frayed insulation that could easily have arced n started a nasty fire between my legs. I clipped the connector off and used heat shrink n electrical tape to protect the cables n had no issues after that.

      Vibration is the devil.
      My ebike is still in shakedown mode.
      I really need to pick up some high ampacity flexible wire and replace most of what I've done.
      I used 10 gage stranded, but calling it flexible would be a lie.

    My late uncle used to pay us kids to unbox pallet loads of goods and put UL Listed stickers on "goods" we were very busy. That was many decades ago.

      I have worked with Underwriter Laboratories for years. After something gets approved UL doesn’t put stickers on anything, what they do is allow companies to put their approval on products that have actually been approved. I know from personal experience that UL will go after companies & people that claim they are “UL Approved” when they are not, and the are relentless!

      @Treasure Traveler not in this case.
      In a bizarre twist,... years later, I was invited to the UL facility in Chicago's northern burbs to help them understand the safety of a system that I specialized in.
      Don't believe it? Well, they made me wear safety glasses everywhere that wasn't the lobby.
      It was pretty silly given all we did was discuss things.

    I think some people get obsessed with fast quick charging, due to getting a charger that came initially with the e-vehicle having a painfully slow charge rate. I can understand of battery fires perhaps happening with these fast charging attempts.
    I bought a triangle battery of 25 AH, which came with a slow as 2A charger. Which failed after 4 charging cycles of the battery. Looking up the battery cell specs the manufacturer stated a maximum 5A charge rate. So I got a 5A charger to stay within the battery parameters.
    Needless to say, charging time improved and the battery did not get hot during charging. So... don't let the "more is better" mantra get the better of you. The grief isnt worth it, for the wanting "it now" mindset.

    (something new to consider)
    I have a few rechargeable tools, & yes common sense helps a lot.
    fires "might" happen while recharging - most likely old battery (?) a failed or incorrect charger :o
    bad wiring of the tool (or Bike,car, a goofy (wrong) battery, incorrect connections (?)
    all stuff to watch out for. [operate error is prolly the worst thing (so educate yourself And do things the best you can)
    thank you for the great information!
    we might not all have the best fire extinguisher close by. {that would be best & safest} BUT
    water [or dirt/sand] will work as you said.

  • @SmokeyTreats
    @SmokeyTreats Рік тому +1

    Thanks for your vid Micah. I'm so paranoid about potential lithium-ion fire & the charging process/BMS balancing. My charger has never worked like other chargers in that it didn't stay green when finishing charging, but would go back to red for a minute then green for a few seconds then back to red ad infinitum. After 600 miles they replaced the charger & now it seems to work like all other chargers I've ever used, after I finished with their balancing instructions by letting it drain to 20% then charge for at least 12 hours until the red light starts blinking, indicating balancing. I did that 3 times per tech request. And now my battery gets 10 more miles of throttle only use, bringing it to 30 miles total of throttle only use on a full charge, which is plenty fine with me. I lived in fear of battery fire for the whole time it took to put 600 miles on the bike because I didn't trust the tech saying the back & forth from green to red was normal. I'm still shell shocked that it took so long to resolve with a charger replacement, when it should've happened on the first time I reported it.

    • @jawaligt
      @jawaligt 7 місяців тому

      Imo the charger going from green to red and back would indicate balancing is happening, since it will accept a small amount of energy again when the cells have been balanced. This process will go on until it's fully balanced and fully charged.

Too say the least there wasn't a part of the ebike that wasn't hot. End of day brought it in the house to cool down. Now the question, given the above scenario, what effect(s) does this outside heat have on the battery sitting in the sun and also riding in the sun? First time viewer on your channel and subscribed. Great video

  • @nobleharbor265
    @nobleharbor265 Рік тому +1

    Regarding batteries on fire, or potentially igniting.
    The primary threat is the high temperatures that multi-cell packs can generate. This can ignite other items. The secondary issue is the fumes. They are toxic, and potentially contaminate their surroundings.
    There are safer battery chemistries but the potential for fire/fumes is the issue.
    As to extinguishers, water does cool the process, and if nothing else is available it can keep temps down, but it also can spread the potential contamination far & wide.
    Chemical extinguishers don’t reliably work, and can cause their own contamination problems.
    A good choice would be one (two or more) CO2 extinguishers. These both cool, and starve the fire of oxygen, while not adding to the contamination situation.
    But where to charge them?
    Fireplaces (enclosed) or charcoal grills can contain heat, and prevent fire, but the don’t really address the contamination issue. Avoiding a larger fire is admirable, but dealing with the other issues should be planned for.
    Charging in a fire resistant bag or case is a good start. However moving that battery out of a home, apartment or garage is better. Placing the battery/fire resistant container on a movable platform, like a metal cart, preferably with a fire resistant covering of cement board, cut to fit, and replaceable. To contain contaminated battery materials, and shield the owner from fire/fumes/explosion. Note: the fire, once put out may be, or eventually will be considered a contamination event. So the provision of easily removable fire resistant materials helps.
    Lastly, borrowing a principal used with oil lamps the are burned indoors:
    Never Leave A Lamp Burning “Unattended”.
    Over time I’ve also backed up that rule with suitable fire/gas detectors, preferably with a remote alarm and alert function. Though if in person, a detector in the immediate location (on or attached) to the battery/cart, and a backup room mount detector would be best.
    Obviously running a few fire drills to safely remove the cart from the dwelling or garage will help reduce panic. Don’t forget to have a fume/gas, full face mask hanging close by, along wit fire resistant coat/gloves/boots.

    If you *must* charge overnight, plug the charger into a timer, that way if your e-bike takes 4 hours to charge, that's all you charge it for, you can cut the number of hours where there's any risk considerably.
    I do this even with my phone, the charger for that only gets power for an hour, rather than the whole night.

    I have a Ride1Up 700. Three years old, plenty of charge cycles. I have no idea if my BMS is a crappy one. I just do preventive care by:
    1) Discovering early how long the battery (all Samsung cells) takes to fully charge, then getting a wall timer to cut off the charger at that time interval. For mine, it's about 5 hours.
    2) In my very wet environment, I used high qualty electrical tape and sealed up the opening at the bottom bracket where all the cables come out. The BMS connections are sealed, but they are visible up inside there. Some moisture probably won't do any harm, but jus sayin. I also taped around the periphery of the battery itself, which is the typical tilt -out type.
    3) I do not remove the battery to charge it, thus reducing the chance of bending or kinking anything, such as the prongs that go up into the case. The battery weighs 12 pounds and can slip down hard if you lose your grip. Ikeepthe prongs lubed wit hdielectric grease to keep them from getting oxidized or corroded. With me, not much chance, but again - jus sayin.
    4) To reduce battery vibrations, I have three heavy duty ZipTies around the battery trunk/down tube to keep it rigid. I may replace that with a thick compressible gasket in the future.
    After 4000 miles the only thing that has failed are the built-in lights, which I have replaced with a more powerful bar mounted headlight and the usual red blinkies in back, white to the sides. The light failure isn't in the lights themselves, but in the controller, so, I assume vibrations are the culprit. Had to happen as some point, right?
    Otherwise, great bike for the price.

    Hey everyone, I just came across a new e-bike project that I wanted to share with you all. It's called freebeat Morph 2-in-1 e-Bike, and it seems quite revolutionary. One feature that really caught my attention is the ability to charge the bike when using it indoors. That's a game-changer! Plus, the bike's brushless 750W motor with 80Nm torque and a top speed of 20mph sounds super impressive. And with its 80mm front suspension and puncture-resistant fat tires, it can handle any terrain. The Morph eBike also offers a unique blend of fitness and technology, with the Smart Saddle Detection+ feature for performance insights. Let's support this project and see where it goes!

    I have a question for you and I really hope that You will make a video about it and if not I wish you could give me some pointers.
    The question is: how would you proceed to modify an existing battery pack like a 13s5p that you want to upgrade to 15s5p or 13s6p…
    I think you see where I’m going with that but in case you don’t then I want to avoid dismantling the whole pack and rather build on it if it’s possible
    Thank you and keep going bro 😎
