Nice work and thanks for sharing battery knowledge. I fixed my 52V battery by also replacing the bms and it's been going strong for three years. Look forward to more videos.
Positive side of the cells. Stick a pin through the membrane, you will hear gas pressure leave the cell, make sure it's not over 4.2 volts, and they work again. Don't tell regular people this. Your vids are awesome. Another cat from the street. Paul.
Lol np Paul and yeah I've figured that out in those Lipo packs but no way I'll tell others to do that. it is a Lil dangerous if you don't know what you're doing and I'm not using them anymore period. I'm sure you know also even if it's a pin hole if water finds its way in they're that's another problem. would I still use them on RC cars or other electronics absolutely, will I be using them on my bike in my battery compartment next to another huge bomb lol Nope. it will still produce that gas and now it's will be leaking into my battery compartment so not putting my ass on a flammable bomb Hahahaha. I appreciate another Homey from the streets, guess what surviving those streets I definitely don't Wana be taken out now by a battery. lmao be cool Homey! PS what made you say stick a pin in them in this video as this was about lithium batteries. I understand that comment on some lipo packs but I'm sure you meant lipos as your not sticking no pin in these unless you trying to kill me or yourself
Respect because that’s the most important thing because it’s not about us at this point especially I’m electric bike rider I would not want anybody to take any shortcuts and then I run into a problem like overheating or even worse and you know what they even worse is I have a situation with mine. It’s just a shut off when I’m riding. It’s a new battery 48 V 20 amp. I bought it to a bike shop to get fixed meaning for them to install it this new battery for me they tested it. They put it in, but how they put it in. I don’t agree with I might have to take it somewhere else because the wires didn’t match the wire from the charging port. The wire that came out the charging port didn’t match the wire that came out the battery. They had two different connectors so with the guy in the E bike shop was sliced the wires off of one battery use that wire as the charger wire for the other battery I didn’t mind But I told them to solder it. I watch what they were doing. They didn’t solder it. They wired it together and put electric tape around it and put electric tape around it and charge me five dollars now I don’t know what they charge me five dollars. I didn’t think it was gonna be an issue because I thought the E bike shot knew what they were doing. That’s why I bought it there. I could’ve did that myself, but I did a Kapacity test this morning this thing zips my electric bike moves quicker and the battery last longer 100% but then I hit that full throttle to go up that hill and I guess the BMS wouldn’t let me Get that far. The power just cut the power just cut off so I walked back to my house and then I watched a video so I plugged the charger in a wall and then I plugged the charger into my bike for five seconds took the charger right back out of the bike And the power was right back on and the battery still full charge so I’m thinking what they did by no soldering and doing it the right way, and making the connections, secure and strong not with electric tape I’m not a battery expert and I’m just asking for your opinion on what I should do?
This was a great video! I was able to embark on the beginning steps for troubleshooting my Swft Zip battery that got wet and stopped working. Was able to bypass the BMS and probe the battery successfully with the help of this video. My tester lite up like a Christmas tree. Next step is a BMS replacement. Hopefully all goes well on this phase of the project. Just wanted to say thank you for the knowledge.
Dude I was just riding mine today and pop and it felt like my front blew out kinda it was a pop but maybe not as severe as the tire but while trying to research came across this vid by far the most helpful video I've ever seen while trying to learn something/anything thank you And thanks for not explaining why a 7/8 socket won't work for a 1/2" and lefty loosy like I've never taken something apart it was just exactly what I was needing to know maybe you can make a video on how to make an actual not annoying for 75% of the time video please and thank you
bypassing the bms for discharge is fine as long as you keep your eye on the voltage ,the bms would still be fine for charging ,i would defenetly be checking the voltages of each group of cells ,the bms doesnt ballance
Nuff respect for the battery bms class ! Your really informative! You are really the best bro, I bought some batterys ( co2ob) lithium ion polymer, Im looking to build a 8 kw battery, and I need some advice about getting the correct bms if I get a asi bac 8000 controller. I really respect what you put out and I will make a donation to you for the information I need, because you really are on a different level to all the others, I would have paid you to build my battery but I bought them before I found you on RUclips
I'm going for range ! As apposed to top end speed Cos I want to tour Jamaica with my E-bike when I've finished building it , your a huge inspiration to the whole e-bike community world wide ! Mad respect!
OK, let me give you the specs. It’s a Jetson bike electric bike Jetson j5 with a 350 W motor stock and the controller. It can handle up to 52 V so it goes from 24 V to 36 V to 48 V to 54 V or 52 V or something something like that, but that stock the only thing new is my battery and I already explained the situation but the BMS saved my butt literally I think it’s because it’s not a secure connection. Do you agree?
Man I just learned so much and everything I needed to know at the moment. You're a mfin' genius ! You should teach electronics that was a fun and extremely informative video with description on how it ALL works. Deuces!!
I want to put an xt60 connector on my 48v lithium ion battery. There is No on/off switch so.. can the wires just be cut and the xt60 then be soldered on ? Or can something catch fire or .... someone get hurt ?
You need to order one the correct voltage with the amount of output amps you need for example if it's a 72v36ah with a 150amp discharge rate you need a 20s bms capable of 150amps. Whatever spec your battery was get the same size
:-: You seem very informal.. I have a question.. I just brought a scooter and have had it for less then a 4days.. The scooter gets a full charge, turns on and will ride.. However the issue is there is never no telling when the scooter just shuts off on me.. Its a 60v 25ah battery yet Ive only got anywhere between 50ft to 8 miles before it just randomly shuts off.. all those times it showed more then 57volts on the Voltmeter displayed on scooter. What could you think this issue may be. Even if you dont know, whatever information would be appreciated.
@@ChrisCrossingWires1212 :-: Well it will shut off I normally just walk it home and put it on charger.. I did a couple time not put it on the charger and just let it sit there (due to frustration). I came back to scooter a hr later and turn it right on, it also showed 64.5 volts on voltmeter.
sounds to me like malfunctioning bms.you have the voltage but something is saying you have too little or too much current, most likely when you use the throttle.ive had something similar.take it apart and check connections.if all cells work then its bus.you need to replace it.thats my guess and thats all it is,im new to this stuff.take it to a professional.@@iammrwack
You are asking Can I fix it for You? if thats the question absolutely I know I can fix it. Need more info what exactly is wrong with it? Voltage too low? wont charge? no volts at all?
@@ChrisCrossingWires1212 Ok my friend, Yes it will not charge, when i plug in the fast charger the charger fan pulsates and counts down the voltage numbers on the display. I've replaced controllers and DC Converter still same issue. I did notice I'm only getting spark on one side and not the other. It's a 60V 49AH battery - Dualtron X 1st Gen.
hey is there any way i could make my charging port for my stealth bomber EV charge station compatible? or what will i need? i know you can get the adapter to them but i want it where i dont need one and can charge my bike within an hour at ev stations!
Hey man I need some help. My scooter had a bad battery so the company sent me a new one but it came with a female plug instead of the male that the old battery has. Any advice?
yeah I say take the old one off and slice it on to the new cable for now temporarily, if you can unsolder it do so and solder it on the new one if it's crimp like I said cut the wires long enough you can twist them together and tape well. Do that just to get going but order a new plug the correct one and do it right or have someone that can.
Yeah I've learn those Lil tricks since this video and even improved on working on these battery's to the point I'm building some high output race packs but idk my phone still let's text and calls come thru on airplane mode I just lose net and wifi
I would say never take that off. Have you ever seen the battery fires? If you smell that thing does it smell burnt from the bms? After the fires I've seen I want to get one of those Fireproof battery bags man it's really bad if one of those Burns real bad
if you're clueless yes I concur stay in your lane, besides Edgar are you gonna do? tell the people that bike these abs their own not to build them? it repair them. They're are people qualified to do both and they're are some people that should just ride and bypass these DIY videos all together. Sounds like your in the second group so that would be fun your standpoint and sounds like your right where you should be. I'm a electronics tech, a real one not a back alley guy so I make these videos to teach those that do have the skills and the aptitude a safe way to do so but I agree, if your just a hobbiest and don't have a clue. Please don't do what I do. I say that all the time. also the BMS and the battery are two different components, BMS blow all the time, that does not mean the entire battery is shot, the battery makes love guys that would buy a whole new battery because of that, so do I
@@ChrisCrossingWires1212 no I'm not a tech guy. But I'm not exactly Clueless. And when I went to go look for the second video I couldn't find it cuz I can only be back to 7 months back on your videos. I'd like to know how you know what group I'm in? Cuz I'm in the group that has to fix their own stuff cuz they can't afford to buy new stuff. Good thing it had the BMS or the garage would have burnt down. Just because I'm very scared of battery fires doesn't mean I'm in the second group you mentioned. I'm the kind of person that has one leg and was thinking about getting a wheelchair and got the bike instead.. I'm the kind of guy that rode my bike 30 miles to the lake with one leg cuz it's electric. I was kind of hoping you would say send me the battery so I can fix it because what I've read about fth there are hidden fees. I'm trying to find out I emailed them. So I have a question if I do not buy the right battery charger but it's the right bolts 54.6 and it's a crappy one can it burn up my bike battery kill the BMS or whatever it did I got to learn how to do this. I know one thing it's not the fuse and I did not break the seal yet but I'm thinking about it cuz I don't want to pay all that money to send it back and then have them tell me some stupid story and then it'll cost more than a new battery when they should just be sending me the BMS so I can put one in but if I put one in do I have to start it somehow or reset it or something? I was watching your videos for quite a long time. I don't know what kind of music you like but I got a lot of music on my channel and then RUclips sucks they're all about getting the money and I just wanted to do videos and they will tell me things like a song I made was copyright protected things like that bands play a song a cover song and then RUclips will say it's copyright violation cuz it's a song by The Rolling Stones or something and they put ads on it and I don't like ads.

@@LetArtsLive I couldn't read all this right now but I will and no you don't have to be in any of those groups I mention but there are plenty that do. I can't lump everyone in the same groups as there are the exceptions to the rule group, however I do have a scared of lithium battery fires group and before you object I'm not only a member I'm the president of that group too lol
I have a 48v battery but came with a 42v charger. The battery charge terminal has 42v and the output is 37.4. You think there are any issues with the battery or it’s ok 37,4 on the output?
I left out some steps that would needed to be taken had there been other problems but that was the problem with this particular battery I guess I'll have to wait for a pack that has bad cells to show how to isolate them and replace.
I am Dan in Batavia New York. I have an eco-trick hammer e-bike. I bought a battery from fth which is supposed to be guaranteed for 2 years. It will not be guaranteed because I bought an aftermarket charger cuz I was stupid. So I don't know if I want to pay the $60 to send it to them when they're going to tell me I f***** up. I figured it would shut off I left it plugged in for a week. I went to get my bike to go pay bills cuz that's my only transportation. My bike would not turn on. Well the battery has an RCA plug and it Sparks every time you go to plug it in. But I think I screwed up cuz I left it plugged in so long and it smells burnt and it's not the fuse I know that. My bike works with the other battery that came with it. I wanted more batteries for more range and less range anxiety. I really believe one of the cells must have burned or the BMS burned cuz something smells really burnt like electrical burn. Too bad you don't live near me LOL maybe that's what it is the BMS.
@@LetArtsLive I'm pretty sure it's most likely the BMS I come to NY on occasions just to group ride with S3 and Gotham. you may be able to ship to me and I'll bring it in a return trip. I'm definitely coming back before Summer is over
The battery smells burnt the light comes on for a few seconds it used to only come on for less than a second I thought it was overcharged but it smells burnt does the BMS smell burnt when it goes? Cuz yeah I can put a BMS in it's a plug it's going to cost me $120 to send it to them and back but if it's a battery that's blown and I open it up it's not guaranteed anymore
There is one fuse on the outside that comes out with a screw that works because if I take it out it doesn't work and I put it in does come on the light
@@AboveDaInfluece bro you have to follow up I got a ton of people hitting me up no way I can track them all youd have to stay on that months ago that pack prob toast now
Brother plzz tell me how to open black cap because black cap connection of my bettery is breken plzz tell me how to repair it I cannot send you because I am from Pakistan Blzz tell me. Thanks You😊
I'm here because I didn't get any light while testing, but knew there was voltage because I accidentally crossed the charging cable and it popped. Hope it didn't fry anything.
if you used a meter instead of a lamp, then you might have found that the cells were unbalanced - the bms would look faulty f it had done its job and shut down the battery to protect it
If you had looked at the date of this video you would have seen that I was just getting started, 2 years later and I'm building battery's and bikes so I'm pretty sure at this stage there nothing you could tell be about a battery that I don't know but much appreciated but this is way outta date considering how fast I move

I really believe one of the cells must have burned or the BMS burned cuz something smells really burnt like electrical burn. Too bad you don't live near me LOL maybe that's what it is the BMS.
@@LetArtsLive I'm pretty sure it's most likely the BMS I come to NY on occasions just to group ride with S3 and Gotham. you may be able to ship to me and I'll bring it in a return trip. I'm definitely coming back before Summer is over
The battery smells burnt the light comes on for a few seconds it used to only come on for less than a second I thought it was overcharged but it smells burnt does the BMS smell burnt when it goes? Cuz yeah I can put a BMS in it's a plug it's going to cost me $120 to send it to them and back but if it's a battery that's blown and I open it up it's not guaranteed anymore
There is one fuse on the outside that comes out with a screw that works because if I take it out it doesn't work and I put it in does come on the light
I don't know Electronics I know house wiring I have a tester
Hi.. new sub here.. i have a battery 48volts my terminal has 0 volt but charging port connector is 36... is it changing about bms?
Definitely sounds like you blew the BMS
Just hit a bump and e-bike shut off took battery off pit back on and sparks shot out bottom
Bro i asked severals montha back if you fix my battery pack and you said yes but nerve got back to me. I have a 52 volt 18 ah lithium battery pack
@@AboveDaInfluece bro you have to follow up I got a ton of people hitting me up no way I can track them all youd have to stay on that months ago that pack prob toast now
Brother plzz tell me how to open black cap because black cap connection of my bettery is breken plzz tell me how to repair it I cannot send you because I am from Pakistan Blzz tell me.
Thanks You😊
you mean the bottom half of connector it snaps on, Ithink thats part you mean if not what black cap?
I'm here because I didn't get any light while testing, but knew there was voltage because I accidentally crossed the charging cable and it popped. Hope it didn't fry anything.
use a multi meter but you probably have a bad bms
@@ChrisCrossingWires1212 yeah I'm jumping straight to the conclusion yours came to, I'll still follow the leads to be sure.
if you used a meter instead of a lamp, then you might have found that the cells were unbalanced - the bms would look faulty f it had done its job and shut down the battery to protect it
If you had looked at the date of this video you would have seen that I was just getting started, 2 years later and I'm building battery's and bikes so I'm pretty sure at this stage there nothing you could tell be about a battery that I don't know but much appreciated but this is way outta date considering how fast I move
So after the battery is shut down how do you reset it if you replace the battery and make it good again
you do good
Part 2 right here ruclips.net/video/HCQRtQ1P5Rc/видео.html
OK, let me give you the specs. It’s a Jetson bike electric bike Jetson j5 with a 350 W motor stock and the controller. It can handle up to 52 V so it goes from 24 V to 36 V to 48 V to 54 V or 52 V or something something like that, but that stock the only thing new is my battery and I already explained the situation but the BMS saved my butt literally I think it’s because it’s not a secure connection. Do you agree?
