How to trouble shoot a bad 48v or any ebike/scooter battery and fix it.  

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

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!

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

I don't know Electronics I know house wiring I have a tester

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.

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.

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

Yes you can

For which bike is your same battery for?

:-: Also great video.. Very very informal even in the comments.

When it shuts down does it come back after a power cycle or do you have to fully charge it back up?

@@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

@@franksaunders-ot3ig :-: They sent me a new battery around that time, I still have old battery also.

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

Definitely sounds like you blew the BMS

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

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 RU-vid 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 RU-vid 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. You should not underestimate people because they might know something you don't

@@ChrisCrossingWires1212 and I didn't get the love lol like everybody else got a heart I didn't get anything

Sorry Bro I'm out in the field riding, everyone gets the love lol

@@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

you mean the bottom half of connector it snaps on, Ithink thats part you mean if not what black cap?
