Do you have a video on how to read the voltage using the voltmeter? I'm an absolute newbie, but willing to learn this stuff. My ebike's dash looks very like yours in this video. My voltmeter is analog
Hi! I just bought an ebike from alibaba, and I am having problems starting it, the bike is already premade and was tested running before it was shipped. Now that I got it, I put the key and it wouldnt start the LCD screen and motor, the horn and the security burglar alarm works however. Any advice on this?
Hi Edel, Perhaps some pictures would help me help you. I need to know more about the bike. Things like the bike type, model, voltage, how old etc...???
Hello Sir Please let me know if you know of a solution with my issue. I have an older Gio 48 volt 500 Battery is charged and showing around 44 Volts (I serviced and charged each 12 volt cell separately) When battery is plugged iin to bike , only things that work is the horn and the signals. Nothing else. No lights and no motor. I have voltage passing through the breaker under the seat. Any advice ? Thank you
if the battery is indeed fully charged it should have a higher voltage than 44 volts should be around 52 to 56 volts if you charged each battery the voltage on each battery should be 12.8 to 13.5 volts check each batteries voltage after they have charged and sat for an hour or 2 if the battery voltage is still below 12 volt then the batteries are not holding their voltage. plug the charger in and turn on bike. Charger light must turn red.Turn throttle if bike wheel turns a little then charger is working and batteries are probably no good
@@GreenStreetOnline thank you. Turns out my one cell is causing some issues. I’ve brought these cells back from being dry and dead using Epsom salts and distilled water. Have you ever had luck doing this ? I don’t yet know how strong they will be. Thanks again.
@@MichaelPick1 yes we tried that years ago works maybe for a few days then no good anyway would not waste the time. Sorry to say you need new batteries. These batteries are not ment to be wet cell,
@@GreenStreetOnline thanks for the info. Do you know where I can get these 12v cells for less than 60? Seems the going rate around here. (Southern ontario)
HI GREEN STREET; MY BATTERY IS GOOD AND MY WIRES ARE GOOD BUT I TURN THE THROTTLE AND THE MOTOR JUST LOCK AND DONT TURN CAN YOU GIVE ME AN IDEA OR TELL ME WHY? THANK YOU IN ADVANCE AND FOR THE VIDEO....
Hi there If motor tries to turn but locks Check wires from motor to controller there are 3 thicker wires probably Green yellow blue .one or more of these wires maybe melted and causing the motor to lock when throttle is turned.
Hi good vid I was thinking of upgrading the lights on my e bike like the one in this vid but I don't know if the new less will work my bike is 36v can I change the lights to 36v led lights
your bike maybe 36volt but your lights may be 12volts or less.You will need to check the voltage at the place where you want to install the LED .use a volt meter.you can use leds you just need to know what voltage you are using.If it is 36volts then you need to use 36volt compatible lights.be very careful not to cross terminals
@@pollifu i do not recommend you do it that way.it will unbalance your batteries.look for 12volts in your harness if it has dc converter in the system it may have 12 volt coming out of the harness .Do you have a voltmeter?
I have an ebike kit and just got a new battery the battery has power and the ebike works because it turns on with the old battery but wont for the new one i was wondering if you could help me thank you
you need a volt meter to test what voltage is present when ignition key is turned on.Not sure what kit you are using lithium or lead acid. call me at 705-775-4545 I will be able to help you further sorry for my late response busy time a year for us
Green Street hey just say your comment one of my neighbors has experience with electronics and he was able to fix it for me the next day thanks for offer though i appreciate it.
Green Street. I replaced my batterys last week cause i thought the were dead. But with the new batteries i still have the same problem. My bike will charge and turn green and say i have 68.5 volts. But as soon as i start to drive it it drops down to 58.5 to 59 volts. Any ideas of what could be the problem?
Hi, i have a problem where my ebike dies whenever i throttle for too long or too much, then i have to reset my breaker to bring the power on again, can you tell me what the problem is? I hope you can help, thanks
How old are the batteries? How far do you go before it quits? does the breaker trip when you hold the throttle too long? if so i would replace the breaker they have a habit of getting weak If the breaker does not trip and the bike still quits under load then that would suggest that you have weak batteries. They may show full charge but are not actually storing enough amperage while under charge.It only takes 1 or more bad batteries for this to happen.Also charger should be tested.
I plug my e bike in it goes green , that good and then I plug it into the battery’s it goes yellow and after little bit it goes flashing red what do .?
Turn bike on with charger still plugged in to bike make sure back wheel is off the ground turn throttle what happens? If wheel turns ok shut charger off if bike quits your problems are in the battery pack.ie connection or bad batteries. Hope this helps
Hi there.Need to know a little more information to help you with that. What are you wanting to get out of the bike.I assume distance and speed,more power? If so I will need to know bike voltage as seen on your charger label if available cheers Verne at Green Street
My ebike keeps shutting down and I have no clue why. The voltage is good and I've checked and even replaced all my connectors. I've opened the battery pack and tested the bms and checked if there were any loose solders or connections. I can't figure it out. Any ideas or experience with similar issue?
Hi Clinton yes I can probably can step you through a process of elimination please feel free to call 705-775-4545 if you can not , I will need to know a little more info to help me help you 1/ how old are batteries 2/ where did you take your voltage check from, you should be measuring voltage at the charge port. 3/ what is the voltage out put of your charger 4/ are you loosing all power from the dash 5 are you loosing power under load ? 6 are you losing power over bumps? 7 do you have and know how to operate a volt meter. I f not i will need to give direction on the phone answer these questions and I should be able to get you going. I am assuming this bike is a lithium battery pack because you said you tested the bms (what sort of test do you mean on the bms)If your battery keeps shutting down like someone is shutting it off than the problem is likely a defective cell in the battery.Or maybe the charger is not working properly This would mean that the battery needs replacing if the charger is working fine. some pictures of your bike and battery pack would be helpful as well cheers Verne from Green Street ebikes
Green Street Could we do this over Skype or messenger? I'm in australia. I don't think my carrier let's me call international. I'll get bang to you about those questions when I can access my laptop.
Green Street, to answer those questions..1). The battery is about 8-9 months old. 2). I measured the discharge wires. First at the end of the wires and then at the base. I didn't think to measure the charge connector. How do I do that? I have an RCA connector and its the female end (or maybe the male. It has the pin but its enclosed around.) I tried to measure that but sparked because the space is so small. 3). My previous charger was 54.8v when I measure (it blew recently and using a spare charger). My spare charger that I'm using now is measuring 53.5v but I'm now only charging to 53v.4). I don't have a "dash" so to speak. I just have a twist throttle with a digital indicator. But yes, when it happens, that goes blank. Actually, when I'm in full throttle and it happens, it drops to 20 something volts. I'm not sure because when it happens when I'm just taking off, it just goes blank like There's no power. 5). I lose power under load sometimes and sometimes, I haven't even mounted the bike.6). No, bumps are not effecting it. It happens on smooth terrain too.7). Yeah, I know how to use a volt meter. Mainly familiar with the DC settings and the continuity setting.Yeah, its a Li-ion battery. I tested each series (white wires going to the white connector on the bums). The first I took it, they were all around 3.8v. This was after a long day of riding. I think I also tested some other stuff but I forgot what that was. I think I need to check that one again. And on later tests, I tried measuring the series again but kept accidentally sparking them because my probe kept touching 2 at the same time. I was getting too nervous to continue to get all the readings. So, I'm not sure if they're all level. At first, I thought it might have been a bad charger, since my last one blew, I didn't get any issues, until today. I changed an old extension wire and some connectors but its still shutting down.
Hi there sorry for not getting back sooner It really sounds like there is something going on with the battery pack. To check the voltage on that rca connector you have to put the positive probe down into the middle and touch the out side with the negative. Testing the bms voltage of each cell you should see at least 4.2 volts with the batteries fully charged with no more than .2 variation between each cell.Anymore than .2 variation the cell is no good.Allways test the cells knowing that they are fully charged.I have bypassed the Bms before but i caution against this as it becomes a fire hazard with out the bms in there .If all voltage is good on all the cells than i would suspected a faulty BMS.This is where I usually stop and replace the whole pack.Remember that the battery is only as good as the worst cell in the pack.With the pack only being 8 months old maybe there might be some warranty as most lithium packs have 1 to 2 years warranty Your charger voltage seems low for a lithium.The voltage you have coinsides with a lead acid pack charger voltage.LIthium pack will charge at approx 56 volts. Not sure if I can help you any further cheers Verne at Green street ebikes
I appreciate the information because some people need to do their own repairs due to the fact there are no repair shops in the area.
so true
Thx for the help best video on this problem I have come across yet!!
Thanks! glad it helped
Connections are everything
oh yes for sure!
Always start with the battery then begin the process of elimination checking voltage on both sides of the connections will save you alot of fustration
