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.
@Mr. E thanks man. Even as nervous as I was Vee was Fantastic every time I heard from him. Over all given how swamped they are because of the beginning of the season he's been great.
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!
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,
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.

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%.
AWESOME TO READ… 🙌💯💪 Thank you for that… 🙏 My battery totally transformed my journey as I’m sure it will yours… Ride Hard…! Ride Fast….! But most importantly… Ride Safe hommie and welcome to the TEAM… 🙌💯💪
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.
Man to be honest that sounds like a disaster waiting to happen. Do not put battery packs in parallel if you dont know what you are doing. Individual BMS's on packs that you put parallel will not function correctly as you are increasing the stress beyond what the batteries are initially rated for. Thus discharging them further than they should. Lipo's for example will do this more, but you will also be able to monitor them correctly AND they are rated for pulling alot more amps out of them.
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).
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.
You should NEVER run an ebike battery pack without a BMS! And make sure it's a competent one too. It's totally unsafe and inefficient for the batteries, But people really do do it.. It's not actually uncommon, and I'd bet a good wage that a majority of fires are caused because of this or a shit BMS that failed it's job.
@@helenHTID battery balancing is a costly feature, but i would not order a battery without it. With it, the bms can monitor each cell bank and try to balance out the voltages.

@@lostthebox4403 You're talking 40 - 60 bux depending on pack specs, Not a cost worth skimping out in any circumstance imo. (I'm talking building yourself, Bulk build factories probably get discounted, And repair services will charge more)

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..........

You and me both… These topics are gaining in popularity so I’m sure you’ll see more and more like them… I know @sparkcycleworks is also posting videos about lithium batteries…
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'!
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.
Thank you… it is well worth the investment… I was immediately convinced the first day I rode using a Powerful Lithium Battery… You’ll thank yourself later…. 🙌💯💪
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 !
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 👌👍

If your building them then you understand the importance of maintenance... Its those that don't that need the reminders... But accidents do happen and the BMS help to prevent accidents... Making them essential... 💯
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.
You know what I’m going to say… Powerful Lithium Makes THE BEST batteries on the market… They use the BEST cells and materials… They ARE NOT cutting corners and they PUT EMPHASIS on safety… I’m there very often and I get to see it first hand… as well as I see repairs they have made on other manufacturers builds… I get to see what the other guys are doing as well… 🙌💯💪
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
Hey if a battery catches fire 🔥 you will need to let the process happen… If your battery is built with integrity and using the best parts you should not have to worry about fires… The fumes should not be breathed in and if you can or have access to a large body of water might be good to throw it in there while it’s smoking do not breath in the fumes…
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
Poor quality in build will show its self through the covering… 💯 Buy reputable… what you’re saying is both good and bad at the same time… the only reason I think it’s bad is if it’s custom build you don’t want to give away your idea… So sorry for the late reply… 🙌😉🙏
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 😤😤😤
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.
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
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.
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.
Definitely don’t cut corners on a battery… save money elsewhere… Sorry but I’m jumping in this one to remind someone trying to save sone money to use my CODE 🚨 MRENYC 🚨 and that will save them $100 😁 Thank you Smooth 🙌🙏🫶
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 .
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.
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.
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.
You are suggesting V put his life in danger just for your benefit… you need someone that been certified and taken many courses and been doing fire prevention videos for years to create a controlled environment so they can demonstrate how deadly a poor build battery pack is.
No examples or video of real ebike fires. You tube has alot of posted ebike fires. Alot of folks have never seen just how violent a battery fire really is. Plus they never showed what a properly built battery looks like. The owner of this shop totally missed the opportunity to show how well his batteries are made. The thought behind the making of the video is commendable but the video was poorly made with nothing more than a bunch talk
@@jimmyelliott7473 you just said UA-cam has a lot of them so why should powerful lithium risk their lives for a video to make a fire? Which again needs to be in a controlled environment. 2. You ever watched the documentary of McDonald’s and how they had the best assembly line but let their competitors come in and watch them how they do it so that’s why bk and Taco Bell copy them. My point is why is V and powerful lithium gonna show how their battery are build on camera so their competitors can see it and copy it?
@@jimmyelliott7473 To be fair, and no offense to Mr. E, this video was shot and produced by Mr. E, not by Powerful Lithium or their owner, V. Saying V did a poor job show casing his work in this video is not his fault.
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 🤙🛴🚲
It’s crucial to take care of your battery and familiarize yourself with the BMS app… monitor your cells and look for abnormal readings… this could be a great topic for a future video… Key note here is know you battery specs and life cycles… look for abnormalities especially when you completed your life cycles… Also overcharging is a big concern… Me I experienced an overcharge where my BMS did it’s job and successfully turned itself off to prevent overcharging So please don’t leave you battery ever charging unattended…

You and me both… These topics are gaining in popularity so I’m sure you’ll see more and more like them… I know @sparkcycleworks is also posting videos about lithium batteries…
I totally agree mate definitely some things I didn't know about great guy very knowledgeable
@@mr.e_from_nyc I hope so. Can’t wait to see that video from them. I’ll be on the lookout.
@@ericarroyo2092 you and me both…
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'!
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.
Thank you… it is well worth the investment… I was immediately convinced the first day I rode using a Powerful Lithium Battery… You’ll thank yourself later…. 🙌💯💪
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.
Invaluable information here, thanks for sharing!
ErooooooooocK… thank you 🙏 you already know… 🙌💯💪
Excellent knowledge shared here. Thank you! Very well done all around. ❤❤
Thanks so much for this… music to my ears… I am surrounded by so much talent… I want to share with anyone who will watch and listen… 🙌🙏💯🫶
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… 🙏 Greatly appreciated… This pack is a tragedy waiting to happen… 🙌💯💪 So sorry for the late reply… I missed this notification…
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 👌👍
V is awesome…. 💯
That’s exactly what I’m talking about… I want everyone to be safe out there… last thing I want to hear about is another fire on the news… just know if they happen this is why… 🙌💯💪🫶
@@mr.e_from_nyc I waited an extra 6 weeks before getting my ebike on the road just because I wanted to have enough money for a good battery and I'm glad I did just wish I new someone like V in England loveing your channel mate nice one 🚵👍
@@ebikeoutdoors thank you so much for that… well I’m glad you’re back on the road… if the team keeps up the hard world they just may open a shop near you lol 😝 and I will ask for a test ride when I visit… 😁👍
thanks Sir for the info. When living in an apt no way to know if people have this inside waiting to burn
Very scary… 🙌 Thanks for commenting and sorry I missed this notification
I have been building my 18650 ebike batteries for 5 years without any bms and never had any issues..
If your building them then you understand the importance of maintenance... Its those that don't that need the reminders... But accidents do happen and the BMS help to prevent accidents... Making them essential... 💯
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.
You know what I’m going to say… Powerful Lithium Makes THE BEST batteries on the market… They use the BEST cells and materials… They ARE NOT cutting corners and they PUT EMPHASIS on safety… I’m there very often and I get to see it first hand… as well as I see repairs they have made on other manufacturers builds… I get to see what the other guys are doing as well… 🙌💯💪
@@mr.e_from_nyc taking your word for it. I appreciate it 🔥💪🏽.
@@Loveveryday-f9j 🙏🙏🙏
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
Hey if a battery catches fire 🔥 you will need to let the process happen… If your battery is built with integrity and using the best parts you should not have to worry about fires…
The fumes should not be breathed in and if you can or have access to a large body of water might be good to throw it in there while it’s smoking do not breath in the fumes…
first there are fire proof boxes, second you could alternatively use a metal box to charge the battery in, for extinguishing i recomend Sand
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
Poor quality in build will show its self through the covering… 💯 Buy reputable… what you’re saying is both good and bad at the same time… the only reason I think it’s bad is if it’s custom build you don’t want to give away your idea… So sorry for the late reply… 🙌😉🙏
Great video !!!
Sorry I missed this… thank you… 🙏
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.
21700 celss
So glad your building my battery and bike gonna have a safe well built bike that will never fail⚡️⚡️💯💯💯💪🏼💪🏼💪🏼💪🏼💪🏼
💯% Welcome to the team… You will have range for days… 🙌💯💪
Mobile phones and laptops have always exploded but media keeps it quiet
So true… so sorry forgotten late reply… I missed the notification…. 🙌💯💪
Great video.
Thank you James… 🙏 I really appreciate that… 🙌💯💪
Vee I could watch these videos all day very informative keepem coming thanx Mr e
You’re welcome and thank you for your comment… 🙌🙏🙌 Greatly appreciated 💪
Isn't it ironic that powerful lithiums batteries are the ones who keep catching fire now.
Ironic…? You mean fake news from Dirty Sanchez
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
My battery is still going strong in my ONYX after 2 years. 50ah Litespeed 😎
2 years… that’s awesome 👏 how many cycles…? would love to see a screen shot of your cells…
Even tho i don't use a bms i would never build a battery like that.
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.
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
😤😤😤
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.
You know the saying… One bad apple ruins the bunch…
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.
Thank you, super helpful.
Thanks so much for that… really appreciate 🙌🙏🙌
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
link...?
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.
Definitely invest some time to learn about the process… 🙌💯🙌
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.
I wouldn't leave those packs in my workshop!!
They'd be in the garden inside a firebrick enclosure!
So true… stay far away from these… it’s a tragedy waiting to occur… so sorry I missed the notification and the late reply…
Talk about crossing wires geeze 🤟👽🚲🎬
YuuuuuuuuuuuP 🙌 Super Scary 🙌💯🙌
Like the saying goes, you get what you pay for.
agreed... 💯 percent
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
How many was made in America 🤔,
Two words. Holy sh*t.
Bombs is right.
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.
I will relay it and find out…
didnt tony tony soprano was into batterys
hello you build battery’s ?
My personally... Not yet but when the riding season is done ☑️ I will build my first... 🙌 💯 🙌
Who in their right mind thought 4 Samsung 50E’s was a good idea for an E-Bike???
Should be illegal to fuck with batteries unless your qualified
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.
Definitely don’t cut corners on a battery… save money elsewhere…
Sorry but I’m jumping in this one to remind someone trying to save sone money to use my CODE 🚨 MRENYC 🚨 and that will save them $100 😁
Thank you Smooth 🙌🙏🫶
Did you know that Fireworks and Lithium Ion batteries are made at the same factory in CHINA???
no factory / UL rating. I am sure regulation will happen overtime.
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 .
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.
Low power batteries wont heat up
Can you send this guy your battery to be fixed?
YES... 🙌 call and set it up...551-404-4107

LOL, taking advice from a super73 owner.... that's rich.
1:17 What is this shitbox?
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.

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.
You are suggesting V put his life in danger just for your benefit… you need someone that been certified and taken many courses and been doing fire prevention videos for years to create a controlled environment so they can demonstrate how deadly a poor build battery pack is.
Besides starting a fire on purpose just to prove a point, what failures are you referring to ?
No examples or video of real ebike fires. You tube has alot of posted ebike fires. Alot of folks have never seen just how violent a battery fire really is. Plus they never showed what a properly built battery looks like. The owner of this shop totally missed the opportunity to show how well his batteries are made. The thought behind the making of the video is commendable but the video was poorly made with nothing more than a bunch talk
@@jimmyelliott7473 you just said UA-cam has a lot of them so why should powerful lithium risk their lives for a video to make a fire? Which again needs to be in a controlled environment.
2. You ever watched the documentary of McDonald’s and how they had the best assembly line but let their competitors come in and watch them how they do it so that’s why bk and Taco Bell copy them. My point is why is V and powerful lithium gonna show how their battery are build on camera so their competitors can see it and copy it?
@@jimmyelliott7473 To be fair, and no offense to Mr. E, this video was shot and produced by Mr. E, not by Powerful Lithium or their owner, V. Saying V did a poor job show casing his work in this video is not his fault.
I want to buy his batteries Give me his Information please.
I thought it was in the description... itspowerfullithium.com and their number is (551) 404-4107
Where is this shop located?
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 🤙🛴🚲
It’s crucial to take care of your battery and familiarize yourself with the BMS app… monitor your cells and look for abnormal readings… this could be a great topic for a future video…
Key note here is know you battery specs and life cycles… look for abnormalities especially when you completed your life cycles…
Also overcharging is a big concern…
Me I experienced an overcharge where my BMS did it’s job and successfully turned itself off to prevent overcharging
So please don’t leave you battery ever charging unattended…
wtf is that battery wiring bro
Exactly... Its a bomb...
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. 🥲
OMGawd 😱 So sorry to read… hope all is well… 🙌💯🫶
