EBIKE FIRES ARE A REAL CONCERN... (This is why...!) 

⚡👌🏼👌🏼⚡ Please, no more 🔥🔥 😱 that pack is a horror show, whoever made that needs to be locked up for the safety of society

Great. I only look at ebikes with premium brand batteries. Will not consider anything less. But now I have to consider the build quality with those premium brand batteries so Im back to square one. Great video and info thank you for posting.

There are some things you just cannot skimp on your safety and those around you are one of those you cannot skimp on.

I'm so glad I found these guys. I get my battery and bag on Wednesday. You get what you pay for guys be safe out there.

Only 6.3k Views in one month for a video as important as this? ebikes are becoming more and more popular more fires will occur with certain sellers cutting corners on safety, I do not normally say this but this video needs to go viral He has done his home work on this one,

I gasped when I saw the soldered connections on that deathtrap pack. The entire point of spot welding the terminals is avoid the heat load from soldering that could otherwise damage the inside of the battery. The terminals can also heat up during high amp draws, so making sure there's enough spot welds and thick enough bus bars is also a factor. I've also seen now that there are heatsinking compounds that the ends of the batteries can be potted into, to draw out discharge heat. There should always be a liberal application of kaptom tape wrapped around the cells after they're assembled into groups. I have a stock ebike with a basic battery, and I still put the battery inside the oven when I'm charging it. I don't take any chances when it comes to ebike batteries!

I love V so much! He is so calm when giving the real details on these serious situations 🙏 Gonna spread the heck out of this videos

Personally, if I was to buy a new battery for my e bike, I would buy from the dealer/ bike shop that sold me my e bike. This way I won't buy the wrong type. Thank you for this video.

I had a battery fire 2 weeks ago. I have an XP 2.0 and I've made some modifications to it. I made it dual hub motor and had 5 battery packs on it. I had 3 in parallel for the rear and two for the front. All packs were individually charged with their own chargers. What I thought caused the fire was one of the heads of the allen bolts on the rear rack rubbed away at the bag 2 of my shrink wrapped packs were in, worked it's way into one of the packs and must have shorted out a cell. After watching this video, I think it was from road vibration and that the batteries weren't in a case just the blue shrink wrap it came in. I had just returned home from a ride and was in the process of plugging my batteries back into their chargers when I heard a pop followed by a whoosh. I looked down and saw smoke coming out of the bag and started freaking out. I managed to get the bike back into my driveway and started unwrapping the bungees holding the bag on the bike. My roommate happened to be heading to work so he helped me get the bag off of my bike. I managed to carry the bag to the end of the driveway. I had just set it down when flames started shooting out of the bag. Unfortunately I was not able to save the other pack in the bag so I lost both packs but the bike and the other 3 batteries were saved. The fire department came and put out the fire. I'm just glad that I set the bag down upright or it would have been mortaring off little fireballs at my yard. 14 years of e-bike experience and this was the only time that has happened and I'm extra careful with stuff.

Thanx for showing what the problem is. I had a feeling the fire incidents were due to lack of BMS, did not realize they would dare to solder Li-ion batteries. I have ordered 2 batteries ordered from China, saved money and been very happy with them. Both have been properly built with spot welds, balancing BMS, and very well insulated and covered with insulator board on all sides;, plus double shrink wrapped in opposing directions . This is the only way I'd try to save money on a battery, but you do have to be careful of what you are ordering. Typically BMS specs are in the description on packs that include them, I avoided any that did not list that information, or the cells contained.

I learned this before I even got into ebikes, thanks vaping! Unregulated mods loved blowing up in people's faces when they'd done stupid things (not calculating draw from coils, vaping while charging etc.). Education is always going to be the best way of waking people up. The soldered points were more than a bit shocking. Would loved to have seen the customers face when it was explained they'd been riding around on a bomb. 😮 The shop I take my bike into has pointed out how the new generation of cyclist seem to take the cheap route on everything but the bike. We're both of the mindset that you buy the best you can afford for everything but the battery pack. It's just something you don't cheap out on (very similar to buying a quality power supply for a computer, compared to a bargain basement brand that's built like garbage and ends up having no failsafes to protect other components). He's had clients with 6k+ bikes comes in for replacement because they locked it up with a coated wire lock, and unfortunately it's those folks who tend to cheap out on everything (especially someone who didn't realise how much replacement packs cost until they need to replace them).

Man he is such an expert! Wish they could get the dude making these dangerous batteries busted! Thanks much for this vid Mr. E!

That's why I just purchased a 50AH battery from Powerful Lithium for my new Onyx RCR. Thanks to your channel I know about Powerful Lithium and trust them 100%.

Hey Mr. E , I just found this video today and i am sure glad i did . I am from the tri-state area in Central NJ and there are not alot of ebike peeps here that i have found , at least i have not found too many...lol This video is something that needs to be seen by anyone here in the nj-nyc area cause all this shit that is happening with ebike fires in the area , SHOULD NOT BE HAPPENING !!! It makes a bad type of news for the ebike community and it does not matter who it is it is all bad ! No matter if it is a local chinese food delivery service or even Little Dirty Johnny was charging there battery and it caught on fire burning the establishment to the ground..... Well enough rambling from me ...I will try and share thiis video to all i know cause it needs to be spread to anyone with a ebike or whoever uses Lithium ion cells ..... Thanx for this video dude it was awesome ! I am now subbed and I will catch up in a few days so i can do all i can to help..........

I personally have been doing Ebikes for some 5 years I have a shop full of them but have never, never ever had a battery smoke or catch fire. I even keep spares on the shelves charged. I only buy from companies that specializes in making batteries. Have never tried to make my own and would never buy something like he has on his work bench. Just like a car full of gas if the right conditions exist then yes there is a chance for fire. But Lithium ion batteries have been in use for 45 plus years you would think if there were truly an inherent danger to using them it would had been banned years ago. Cell phone, power tools, lap tops, security lighting... the list goes on of things that are not bursting into flames on a daily bases, that All use lithium ion batteries. If this sounds like a rant well it kind of is. I personally get tired of folks asking about the bikes just to say Oh don't those explode into fire!!? I tell them yes that is why I like em'!

I've been window shopping lately for an extended range battery and this video just made my decision easy. Thank you!!! P.S. ~ I subbed!! 👍

As with 99% of everything else, if it cost way less than what it should cost it is likely junk. I always fuse my controller before the battery for extra protection that way you have more than just the BMS to stop a shorted controller from taking your battery out. Also, you should put an Amp Clamp on your controller to see what you are really pulling for amps from your battery. Don't just trust what you think the manufacturer said it will pull.

Oh God, that looks absolutely terrible..... Re-did my Bionx 500 watt ebike batteries. Did a better job than it was originally. It's even safer ! But what I see here is incredibly dangerous and literally puts life at risk of serious injury and death. This battery pack is a nightmare come to life. Electric vehicles and their electronics need to be respected.... as does human life !!! This is an absolutely fantastic video..... Great job !

Thank you for this video! I’m glad Vee is informing us. I wish more companies were like these guys.

Invaluable information here, thanks for sharing!

thanks Sir for the info. When living in an apt no way to know if people have this inside waiting to burn

Man I really love guy's like him who really knows what he is talking about I would really like a guy like that to be able to go to for my ebike needs very interesting video nice one man the difference in quality between them battery's is crazy 👌👍

Excellent knowledge shared here. Thank you! Very well done all around. ❤❤

Great video. Would of liked to have seen Powerful Lithium battery side by side to compare. Bet it's night and day. Saving to switch to Powerful Lithium. I can't wait. Last update I need.

12:00 He mentioned when charging we should keep an eye. What are we suppose to do if it starts to catch fire? What type of rated fire extinguisher is recommended to have to put out a battery type fire? There are different types of fire extinguishers to handle different type of chemicals/fires

Yeah I’m always concerned about this type of stuff.. How do you know if it’s all good? Who makes the best & safest batteries? Safety is always my #1 priority.

I have been building my 18650 ebike batteries for 5 years without any bms and never had any issues..

My stock system is 128 (cells) LG, 21mm x 70mm, 60v stock for my Talaria MX4. I love my power, torque, range; I'm not messing with anything.

Great video.

E bike fires only happen if you have a cheap bike and you charge it right when the battery still hot go with a AVENTON And you won’t have any problems

Even tho i don't use a bms i would never build a battery like that.

My battery is still going strong in my ONYX after 2 years. 50ah Litespeed 😎

I love how mad this battery is. The wire looks like 2.5mm2 aka 27amp rating (uk) Running 40 amps will heat the wires that will melt the heatsrink short the battery. Bms cant do nothing to help a badly made battery, it only helps for .. Cell inblance (not all). Temp and current. Thats about it. Decent battery pack will have fuses between each group. This helps with a short, between groups ,but not an internal short within the group. Pays to go have a proper battery with safety kept in mind.

I think it should be a law that a lithium pack for a bike or any other thing should have a clear case. Good workmanship speaks for itself, but bad workmanship screams when you see it

When I saw that man get fried in the elevator from his e-bike battery a few weeks back, I decided from there I’m gonna do as much research as possible, and all the evidence is showing me that these e-bike batteries are nothing more than a ticking time bomb waiting to go off and I am not willing to take a chance with those regardless, if be charging it or riding on it, it’s not worth it, not my life nor my family. People have died in their homes simply charging these damn things and please don’t give me the nonsense about don’t overcharge it, people charge other devices overnight and they do not combust and explode like this, let’s use our brains people, the people who manufacturing these dangerous time bombs. They need to be prosecuted and arrested for crimes against humanity 😤😤😤

Great video !!!

So glad your building my battery and bike gonna have a safe well built bike that will never fail⚡️⚡️💯💯💯💪🏼💪🏼💪🏼💪🏼💪🏼

It is very stupid to Bypass the BMS. I build my e-bikes and buy battery from a real Company. And I never Charge when I sleep.

Vee I could watch these videos all day very informative keepem coming thanx Mr e

Thank you, super helpful.

Are Amazon batteries safe? I got a 36v 8ah that came in cool little case to power a DIY E-bike, it even came w a charger that has red/green charging indicator on the transformer

Mobile phones and laptops have always exploded but media keeps it quiet

i learned through the pandemic how to build ebike batteries. safety is paramount when dealing with lithium ion cells. i would never build a pack without a bms and insulating rings and cell holders. also i wouldnt solder them together, spot welding is quicker and much safer. i'm 7 batteries in and have had zero issues so far.

Isn't it ironic that powerful lithiums batteries are the ones who keep catching fire now.

I'll never ever buy a battery from anyone I'm not sure about. If it's not UL or CE listed make sure it's from someone you at least trust.

Those are bombs just waiting to go off. No wonder the fire dept is trying to get rid of e bikes cause of that kind of shit.

I wouldn't leave those packs in my workshop!! They'd be in the garden inside a firebrick enclosure!

Talk about crossing wires geeze 🤟👽🚲🎬

It would be useful if the bloke explained that BMS stands for Battery Management System!!!!

6:00 Dangerous to have in his shop! Can someone reveal who built those bad batteries? I hope it's not ChiBatterySystems or EM3EV

Like the saying goes, you get what you pay for.

Who in their right mind thought 4 Samsung 50E’s was a good idea for an E-Bike???

Hi V can you post the dimensions of you 72v 42ah hyperion battery for the onyx rcr, and for the mercury battery for stealth bomber 72v 42ah.

Two words. Holy sh*t. Bombs is right.

Like the phrase goes “you get what you paid for” and look at those bad build battery packs. Ruining good battery cells like Samsung too smh. It’s always nice to save a buck or two but when it comes to safety, nobody should be cheap. I seen people spend thousands on suspension and brakes but not wearing a helmet. Sure motorcycle jackets aren’t cheap but they can save you from a hospital bill. To put in perspective a young girl fell on her rollerblades and landing on her head: we talking 1-2 mph and because no helmet… you know the rest.

How many was made in America 🤔,

Should be illegal to fuck with batteries unless your qualified

hello you build battery’s ?

To many batteries 🔋 in a pack increase the heat while riding creating a thermal overload. Their is nothing to cool them off and a fan is not enough. Tesla has a cooling coil snaking 🐍 through the pack constantly cooling the pack that is why you only see 40+ volt battery packs. Never recharge a battery pack after riding, the battery pack is hot 🥵 and when you charge a hot battery it only gets hotter. Let your batteries cool down minimum two to three hours seriously 😳 no matter what you have.

Did you know that Fireworks and Lithium Ion batteries are made at the same factory in CHINA???

didnt tony tony soprano was into batterys

Ive bought batteries and they wernt cheap but so dodgy built. I now build my own bullet proof batteries . No shortcuts just built properly now . China just rips us a new one and dumps our shores with junk . Life po4 is the way to go but they dont hold as much energy as lith ion does but they dont catch in fire .

no factory / UL rating. I am sure regulation will happen overtime.

Can you send this guy your battery to be fixed?

😮😮😮😮

Koja je vaša adresa ?

👏🏻👏🏻👏🏻

Mr. E, with respect, the interviewee said people bypass their BMS to save money; everyone I know that bypasses their BMS--redirects and enables the flow of electrical current--FOR MORE POWER (more amps from your battery pack). When bypassing the BMS, increasing the power draw is the goal but it must be limited to a particular amperage. All batteries are rated to a certain continuous discharge. Lithium ion batteries are dangerous in the wrong hands; a little [not enough] battery pack making knowledge is dangerous. In lieu of bypassing anything, upgrade the battery pack (higher voltage) and always fully protect it with a BMS. Upvote 7 Downvote Reply reply

1:17 What is this shitbox?

LOL, taking advice from a super73 owner.... that's rich.

The issues with *all* electric vehicles is the innherent danger of batteries. They can explode *at any time* ! We should have never allowed those rolling, ticking time bombs onour streets or in our homes!

Battery fires are one of the reasons why I ride gas bikes. You might think gas is more volatile - I think technically it is - but if you’ve ever been worn out from trying to start an engine that needs more than just a hard crank to start, then you’ll agree with me that gas is, in practice, harder to ignite than a lithium battery pack. Even if they’re assembled properly, Joe E-bike can always find a way to mess around with something he shouldn’t have and burn his apartment complex to the ground. Maybe someday battery technology will be there, but IMHO the lithium battery should have never been mass produced and put in the hands of regular people. It’s just too dangerous and you aren’t responsible enough to handle them. Sorry but not sorry.

Well, ebike fires are real an extremely dangerous and the news media has finally caught on. the news media is broadcasting e-bike fires on their news channels more and more. so you really do need to watch how you treat your batteries and always look for damage to the battery. I don't know where these batteries came from, but there is nobody I know or could think of, that would put this battery or anything that looks like this on their ebike. let alone buy something that looks like this. for this video they should have short-circuited one of those wires just to show you what could really happen. Nice try but this video is a failure in alot of ways. Just alot of talk with nothing to back up your point.

I really hope the person who made that terrible battery stops making batteries but we know they won't. Perhaps exposing them and their malpractice will do something. Who knows where they are but V did say anything can happen at anytime even with one of powerful lithium's batteries. I bought my custom 72v battery from a company in China that's been in the business for 10 years. I believe consumers are quick to blame chinese made batteries without knowing all the details. Proper packaging and mounting can be the life saver or ender of your battery. Best of luck to all the e-riders out there 🤙🛴🚲

Where is this shop located?

I want to buy his batteries Give me his Information please.

wtf is that battery wiring bro

There is a great irony in the fact that my controller caught on fire the day this video came out, luckily my battery is okay. 🥲
