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.
My apologies for the rude comment. I could cite any number of life situations, none being sufficient. Was not my place to cast negativity. I have deleted my comments, I can make no guaranties but I will try to be a better person. Again my apologies to anyone affected by them.
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.
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.
@@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.
@@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.
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.....
For those who also don't speak electronics, I GOOGLED it for us:
BMS means Battery Management System.

To the rest of us looks like "guys just easily look put for the 44hehdb and change out the 34ufufbf"
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!
It so says to do that in the instructions Lol
That's exactly what I do too. I've also started charging the battery in the same room that I'm in so I can keep an eye on it. And as soon as it's done, I unplug it starting with the charger from the wall first, and then the battery. 👌
This is important factual information to put out. The incidents of battery fires in NYC received far more fear-mongering coverage than was necessary. As usual, those who can least afford to upgrade their equipment are the hardest hit by the ordinances.
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.
Instead of going on your conservative rant about NYC you could've realized the big issue with lithium fires in NYC is that the fires are impossible to extinguish and nearly everyone lives in an apartment sharing a singular building. 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
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.
The internal resistance in the cells increases with age therefore old batteries run hotter
We that live in a modern world with cell phones, power banks and a variety of devices deal with a possibility of a battery fire. Great counsel on using appropriate chargers etc. Do appreciate your contribution to greater good with your video's and give away-es... Thanks for what you do.
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.
Thanks for the info on e-bike batteries. I fly electric powered rc airplanes and have seen a few lipo battery fires that happened when the rc airplane crashed and the battery was punctured. Covering the burning battery with dirt and then if possible wet the dirt with water seems to work fairly well to contain the fire and prevent it from maybe starting a brush fire.
This would make a good educational video
I’m in NYC and I’m very appreciative of this video! There is a ton of discrimination towards PEV owners in apartment buildings even if your bike is from a reputable brand. Lots of apartments in manhattan are banning e-bikes.
Tha'ts so true, I hope apartment management companies become more discerning.
A ebike battery maintence article recommended Luna charger . I charge my battery about 1 or 2 hours after riding when battery level 1/2 . Charge at 1 amp to 80% . It was recommended for safer charging and longer battery life .
Thank you for your channel! Finally got the yellow VELOTRIC Discover 2 Days ago. My cousin and I are riding to get into better shape. I’m closer to retirement and want to enjoy the outdoors more even though I don’t have the joints I had when I was younger. Rode it about 3 miles yesterday when I first got it and 30 miles today.
Really appreciate the balanced view you presented about ebike fires. Thanks
Thanks, Micah, great rundown on a sensible view to ebike safety.
Excellent information, thank you for your videos. I enjoy them all.
thanks Micah, for your continued informative videos. i learn something new every time 🚴🏼
Appreciating your insights provided in terms of preventive & proactive action points as well as personal experience regarding e-bikes. Also, the community tips from the comment section discussions are pretty helpful. Looking forward!
another great video with lots of wonderful information
Thank you for the useful information on lithium ion fires and helping calm some of the fears that the news media is so great at spreading. Knowing how to deal with the unlikely situation is great information to have.
Another very useful video. Well done. Thanks
Thank you. I appreciate your clear and simple explanation.
Great info ! Thank you
Thanks for the important information. And kudos for setting up the bike giveaway.
Great safety considerations. When the lithium-air batteries arrives I hope they are or can be incorporated as replacements for current batteries.
❤❤❤ I love your videos man 🎉
Another great informative video. You were meant to do what you are doing because you do it so well. Thanks
Thanks for all the tips. Great video as always. :)
Great video, thanks for the tips.
thank you this is a great video of advice for peace of mind.
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.
No thanks
Gotta keep an eye on my battery and make sure to unplug it once it hits 75%. The charger tends to want to push it above what I need it to do.
I love your videos. An ebike would really help me get around.
Good info. It makes sense that it was the El cheapo ones that cause the problems.
Thanks for the reassurance. I had just ordered my first ebike. Right after, I changed upon a UA-cam video where a guy's $6000 bike becomes a yard-inferno! And I'm thinking "What have I done!?" Watching your video made me feel way better. I had begun wondering if I should have cancelled my order.
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 :)
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.
Yes he was Italian and a great person.
...just sayin' cause it's true.
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.
Breat video subject, thanks for your thoughtfulness
Great Info, thank you for this very important video.
Thank you. Great advice !
An in-depth explanation well understood, thank you. Had some doubts about Lithiums and charging rates for some time. (I'm an Ex-nicad scale custom rc vehicle builder)
You are absolutely correct with everything you are saying!
Hi I brought a Totguard, 26"x4 fat tire folding, I watch your videos and in well informed. Thanks to your detailed teaching on ebikes. I use a small electric fan blowing directly for my battery 🔋 charger this keeps the charger a little cool during charging, I charge during the day where I can keep and eye on the charging time, again. Thank fir all your videos on safety,,I am a subscriber,,
Thanks for the info.
Love your videos, have watched most all of them.
It makes sense to not charge ebike's at night, and I will start charging during the day when I'm not riding it.
As you know, I built my own bike, and it is still running well. I upgraded it from 2k watts to 3k watts. I going about 10 mph faster, but I never find the need to go that fast. It's pretty scary actually.
I would like to build a fat tire trike. And finally build my own battery for it using Vruzend connectors. I have 2 boxes, but will need more.
I haven't been able to restart the ebike journey I was planning, due to family issues, but I am still looking forward to it. Hope to see a few of your videos about ebike journeys.
Bless you Mikey in all your endeavors.
Always riding,
Mike Wiltse
I've had a UL listed EBike for less than 2 weeks. Love it! Having used L-I batteries in cordless tools over the past 3 1/2 years, I treat then with care, charge at room temperature, never buy third party batteries or chargers. I've never had a problem.
Great tips!
Much appreciated. You rock.
I charge my battery on the balcony, if it catches fire it will be on the opposite side of the building from the exit, surrounded by concrete, and easily accessed by the fire department.
Thank you for this video. Great advice. Being retired this would make a great alternative for running errands than using a car.
I do of course keep it in the back of my mind as the reality is anything electronic and high energy batteries can overheat and fail... HOWEVER I agree that this is very far from an ebike issue and hate that the media is misdirecting the blame... As always GREAT Info...
Excellent thank you.
Love your videos!
Really enjoy your videos. I have subscribed.
I would say overall you demonstrated about E-bike fires and the causes of them catching fire really well.
I have been very concerned about fires, my bike is just 4 feet away in my apartment all the time. This video has eased my mind, thank you!
You don't know if he knows what he's talking about 😅
he says in the video that he's built and worked on a thousand e-bikes over the years. He has written books about how to properly build lithium batteries and ebikes. The guy has a pretty good idea what he's talking about. @@PEDALSnPROJECTS
@@PEDALSnPROJECTS I agree. I don't want an E-bike anywhere near my house or on my property.
Great video as always. i plan on switching to a ebike soon doesn't seem like too many ppl in KY have ebikes
:D! Great video, I live in NY and many businesses are cracking down on allowing ebikes inside their building.
Your videos are great
I love your videos. ❤
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.
Lithium ion 18650 does catch fire especially if you upgraded to a fast charger , LiFeP04 n LTO'S don't catch fire
Love my velotric. The one thing ppl should know is that you have to let the battery warmup before charging. The charger won't charge it until it warms up
I wish they would get rid of the hazmat classification for LFP batteries. Those don't catch fire.
I currently own a seated scooter from VoroMotors. My battery is a 72v 42AH Molicel pack with smart BMS overheat and discharge protection you name it. Im still aware of charging my battery especially during the night im always hesitant to charge it while im sleeping (balance the cells overnight). When i know im not gonna ride it for a few days or a week i drain it down to 30-60% and store my scooter in my room. Learned a lot from this video appreciate you. 😊
Do you really think the Chinese will not put the UL hologram on their batteries, just to get around the restrictions, as they will do with any other regulation.
Thank you.
Great video. I wonder if you have any info on Ebikes for heavier people.
hope you do more bike to e-bike transformation videos, there're so many brands and parts online, i recently bought a bike for exercising, i want to turn it into an e-bike and i'm considering what to buy
Excellent video, con mucha información, saludos desde Zapopan, Jalisco México.
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.
Good video
charging in a clean fireplace right Before work commute .
Best advice on the internet.
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.
Nice video. The bikes that you can’t remove the batteries easily, do you think they could make one of the bags to enclose the complete battery inside a fire bag that you can buy for smaller batteries?
Thanks for the information. Oh, I was reluctant to go out and consider purchasing a Evike due to the possibility of having it in my garage, and it be charging and catching on fire, as I sleep. The information gives me options Such as the charging boxes or bags that can be purchased two and close the battery as it charges. Thanks again.
Try and get fire insurance to include coverage , especially in a condo with aware HOA
Obviously, this is a really hot topic. I hope nobody gets fired up and flames you in the comments. Personally, I'm burning with desire for one of your books. I can do this all day.
appreciate the info. sometimes it's hard to find the little details.
Question, if I have the option of charging my e-bike battery in my garage, which gets very hot in the summer, or I can remove the battery and charge it indoors, but then there is more wear and tear on the terminals from daily removal and replacement. Which is the better option?
You're right! The media makes you think that sooner or later ALL E-bikes will explode! HAHAHA Thanks for your reassurance, Micah.
PS.......... loved your update on the E-truck. I recall watching you unwrap that load! Great to see it's still great.
That's helpful information. It's good to know that the probability of an electric bike fire is low.
The classic NYC e-bike tragedy goes this way. Bring the battery inside your apartment, plug the battery in right next to the door & get trapped when the fire starts. Or plug it in and go out for the evening and it burns your place and through the floor below. I’m involved with the renovation of 2,400 NYCHA public housing apartments and hardly a week goes by without this occurring at one of the campuses…
The clips of the off brand scooters igniting was good. I didn't know they were highly prone to that. They're so cheap sometimes it's tempting, but now I'll steer clear.
Question, live in Arizona and the temp yesterday was 111, accidently left my lectric XP 3.0 long range battery ebike in the sun all day. 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
I mostly charge my solar E-trike with 500 watt's of solar. For the winter months when the sun is too low in the horizon I use the Cycle Satiator... I keep it near me when charging so I can touch the battery andf wires to make sure it isn't getting too warm...and buy from better companies.
Thank you for the bicycle! I really appreciate it :-)
Hi. I just found your channel. Great battery stuff..!! I just bought myself an E-bike, and want to add a second battery so that I can extend my range. I don't have the ability to build my own, so I've looked online and found several options. But I was wondering if you still make batteries for folks like me, and if so, how much would it cost for a 48V 20AH battery..? Do you have a "store"/website (I didn't notice a link).?
I am Very close to 2000 miles on an Aventon Aventure. Bike has been great.
Hi just found your page and I'm enjoying it and I have 2 important questions one is i have a 27.5 mountain trike bike but cannot find a car carrier rack for it and second i want to make it electric but don't have a clue of what to get or what to do or start thank you so much
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 never charge my scooter without watching it. I will let it charge and check every half hour until i get close then i check sooner. I always check my battery and wires during charging to make sure they're not getting hot. i never charge right after riding (let it cool for at least 1 hour). Never charge overnight . I did research to find out my max charge amp and i never exceed it.
I padded my battery so it doesn't bang around in the scooter when riding.
When I buy a new scooter I always check the wires to make sure they're fat enough if they're not I replaced them with thicker wires that can handle higher amps.
(I have experience with this type of thing so not recommend it for those who do not have expertise in this type of thing)
Thanks Micah, After surviving my 4/22/23 neck breaking crash caused by a forgotten kickstand, I've noticed my battery only charges to 3 bars... Is this from battery damage and is this battery a possible fire hazard in your opinion?
If so, any possible solution suggestions?
Wow
I had not thought about a bike fire before!
(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.
thank you.
When i was deciding on what ebike to buy, the first thing i would check for is that UL badge. Should i also buy one of those fire proof bags to charge it in?
Do you know if the Velocitek e-bike batteries are Li-phosphate? Also, are there standard sizes for these e-bike batteries? What happens in five or ten years when the current battery dies and you need a new one and Velocitek has gone out of business? Where can you get new replacement e-bike batteries then? What is your advice for dealing with future needs to get a replacement battery?
I bought a Priority e-bike (petal assist) for my wife. I like it and wish I had one too.
That velotric bike checks every box of what I use an e bike for. It is like they woke up one morning and thought, "Hey, lets build an e bike that is pretty good at everything a person who only has a bike needs that bike to do. then lets make it a step through so that even a fat old feeble man can make it onto the seat. I AM that old man :)I am crossing every finger and several toes that I win this bike :)
I love my Smart Bluetooth BMS by JBD. it`s so safe
2 Temp sensors and Voltage & current control and passive balancer.
i charge my 14s11p with 1000W and it never even reaches 35°C
Nice color for a e-bike although yellow would probably look better but himiway is only black 😢
I keep mine in a metal garbage can drilled a small hole in top to put charge wire in to charge & store
