- MakeSure all of your connections are secure and not loose you’re charging Cables should look like they do in my video and should be connected accordingly ! A constant red light (on the bms)is a bad sign that your battery is malfunctioning and having issues,It could be something going on with the battery management system (bms) or one of the component on the board like Or it could be one of the battery cells inside the battery pack having an issue or could be unbalanced Somehow ,This video also shows that your scooter should charge without issues also without anything having to be done to the scooter itself.So again be sure that your connections are secure/nothing is loose.Also Something I did not include in my video that I had a problem with on one of my scooters may also be related to this issue.Follow that black and red wire going up to your charging port ,Lift up the charging port flap And there are too small screws That need to be undone..Take that apart and make sure that both positive and negative prongs They are pushed in all the way ! Sometimes they push out of place after charging the scooter so many times..iv had this happend before ..
Your Battery could be under voltage also so be to check that as well .
You could also reset your bms Externally
The first method for resetting your e-bike battery’s BMS is to do it externally. By that, we mean performing a reset without opening the battery compartment and accessing the BMS directly. To do that, you’ll be using a makeshift adapter to charge the battery through the discharge port, which should cause the BMS to reset itself. You’ll be working with a soldering kit and later with live electricity, so you’ll want to keep yourself protected at all times.
Your adapter will consist of the DC barrel jack and two wires. Using the soldering kit, attach a red wire to the positive terminal of the jack and a black wire to the negative one.
You could also use electrical tape to keep it all together and cover any bare parts.
Remember: red wire to positive, black wire to negative.
You must never let the bare wires touch each other, as that could close the circuit and make things very dangerous.
Perform The BMS Reset
Next, connect the adapter to the battery’s discharge port. Look closely at the port, and you’ll see that it has indicators to show you where to plug each wire. It’s usually printed on the plastic itself. The red wire goes to the positive terminal, and the black wire goes to the negative one.
If it’s working, you’ll see that the light on the charger turns red. Hold the wires just as they are for 15 seconds, and that should cause the BMS to reset itself.
Once that’s done, turn off the battery charger and remove the adapter. You can now check to see if the BMS allows the battery to charge and discharge as normal. You can do this by replacing the battery back in the e-bike or connecting it to the charger.

Thanks for this man - I'm really close to getting this working - can you link the charger you are using? I've got a couple different ones and none of them seem to work.
You can charge from the xt60 power port. Just make a xt30 female to xt60 female adapter. The red charge light on the charger goes on and everything.
That has not worked for me, I can’t get the xt30 (input) or xt60 (output) to work for charging or discharging. Never had any luck getting these scooter packs to charge
Is it possible to charge it only via the xt60 port? Is then the BMS still working right? Because it do not charge via the xt30 port
what charger do you use? i used one from amazon and then it smoked..
Ay man you gotta make a video of whatever the hell you described in your description lol. Tried to read over it twice and it still don't make sense to me.
ive found its the best to desolder bird pcb bms altogether and use one of those red ebay bms instead.
prob works way better! i was getting frustrated with the bad bird bms
That’s pretty crazy that you can just plug it in and it works, I get a pretty solid red light, it flickers a bit but solid. I’ve had to bypass before but I can’t get chafing to work
Damn just checked my cells and they are DEAD I’m pretty sure. That’s unfortunate asf. I get 6v for the whole thing each cell is at a fraction of a volt
I'm about to run 2 of these batteries in series and make a 72volt ebike. Have you ever done this or do you have any tips?
Absolutely I actually made a video of me showing how I run 2 Bird batteries in parallel and in series !
You can bypass discharge and use the BMS for charging only.
Load Power straight from tabs!
Connecting a battery in series is when you connect two or more batteries together to increase the battery systems overall voltage, connecting batteries in series does not increase the capacity only the voltage.
That being said be sure not to over exceed 60 Amps (when choosing your controller)
Parallel Pairing is different your amp draw will go from 60 A to 120 A
@@pjscootermods Thanks for the info! I thought series would double the amp rating. You saved me from frying the battery.
Is there any other way to reset the bms bro ? I’ve tried the one you recommended but it will turn red and still not charge normally
just replace the bms with a new one
@@832738 I did this bro thanks though
Aye bro have you figured out how to turn the new Lime scooters into personals yet? I'm talking about the new new ones that have the Grey removable battery pack in the center of the deck. And it has nice curved handle bars on it. Have you seen them yet out there in Austin? I live in Long Beach , Cali. And I have a plethra of all types of scooters out here. But I want to figure out those new Lime joints....
Lol yeah I bet that’s where all the scooters originated well I know bird did at least ! Those new lime scooters have not hit my area yet. I’ve only seen them online/UA-cam shit like that. I would need a scooter in my possession that way I can break it down and study it.. but I’m pretty sure should be the same deal when it comes to putting it together, nothing really changes
Hey bruh, I just got a charger and tried charging my battery packs. I dont get a red light on my charger at all, bu the red l.e.d on the bms acts the same way yours does and makes that same sound. However, even after like 6 hours charging the battery is only outputting like 10V??? lmk IF YOU have any pointers. Thanks again bruh and keep em comin!
10v is waaaay too low, you've got dead cells. Best thing you can do now is to check to see which cells are salvageable (prob none).
For that you’re gonna have to grab you another battery.. that’s a no go 🙅♂️ ..
Just grab you another battery and you’re good, don’t even try repairing that thing
@@pjscootermodsbro my battery is outputting normal current but red light won’t come on and it won’t charge is the battery bad. No charging noise and the charging light stays green. Battery is at 40 volts rn
My battery is not charging, i checked the wires and its all ok, but charger led is green and the battery seems charging but it doesnt work
Are you able to get the whole scooter running without a new controller?
I do not think so. I have tried several times with zero luck
@P&J scooter mods
I have a charging issue. I only can charge my battery through the discharging port.
I already bridged the pins “b- and RST” but no change.
My charger light goes from green to red and back to green. And the red light is flickering a little bit, while the charger is connected
You should be using the charging port for charging . The little red light that flickers is fine that’s not anything to be concerned about.
Yes, but the light from the charger is still green and after few mins connected the voltage of the battery didn’t increase, so that’s for me a sign that the battery isn’t charging.
And through the discharging port it’s fine for me. Also the charging stops automatically at 42v after it’s reached.
So what do you think, can I leave it like this?
@@pjscootermods look at my answer
Theres a reset circuit you can trip too. I found on mine that when you short the leads on the comm line it trips the bms into protection mode. You contact the rst and b- just to the side of the red light.
@@Danijel_Deni i just did it with a bare wire. Short the two contacts on the side of the board
Where is RST pin? Regards!
@@milosavarsenijevic2560 its along the left side if the charge pins are closest to you. Its a set of four open pins on the pc board about 5 inches up. Just look closely for 4 solder beads in a row and it should say rst under one of the pins
@@milosavarsenijevic2560 theyre outlined with a white boarder so its hard to miss.
@@bradfader691 thanks! Found!
Do you know what the max Amps these bird batteries can do, is 30amps the max like it was on the older bird 1 batteries?
The max amp draw is 60 Amps
@@pjscootermods sick, thanks
@@richardview1281 Batteries connected in series give an increase in voltage, in order to increase the current it is necessary to connect them in parallel.
Doesn't work my battery is messed up it's showing proper voltage on the side that charges but on the output side it's only got 28 volts or something and on the charge side so the charger thinks it's fully charged cuz it says it's 38 volts if you touch the charging leads with a multimeter any idea how to fix these batteries LOL I've already bypassed the BMS I think I shorted it out or something I must be it's been sitting awhile now
Yoooo bro my scooter worked fine and then the bms bypass solder broke and after I connected it again I have solid red light on battery. Is the battery totally done now or is there a fix?? Thanks man
You should use a thick piece of wire when doing your bypass I would say maybe a 10 gauge wire.. it sounds like your wire fried and may have caused a short circuit !! 😬 is your board burnt (bms ) could be a component on the board.. what voltage are you getting out of the battery pack ?
@@pjscootermods bro i burned mine is there anytbing I can solder so I can make it work again the issue is that it doesn’t charge anymore
@@juvenalgonzalez8756 you can always just rip off that bms and wire in a new one. I'm pretty new to this and I've done it fairly easily my first time.
@@richardview1281 where could I buy a similar bms ? They’re all diffrent shapes and sizes nothing that fits in the battery pack itself
@@juvenalgonzalez8756 Amazon or Ali Express. You're looking for a 10s 36Volt BMS. You will have to solder all of the power and balancing wires on. There are a ton of other youtube videos on it.
Hello, I have a problem on my battery the output voltage is only 22v. When I charge the charger indicator remains green but I have 40v on C+ and C- and the BMS red LED remains fixed. I don't understand why the output voltage is so low and no longer charging ??
Swap out the battery , 22v is below voltage, at that point I wouldn’t even mess with it.
So I have a bird 3 I pulled out of the river while fishing I'm trying to charge battery an use it for my trolling motor on kayak but it's only reading 1volt. So is it screwed for sure or is there a way to "wake " it up it blinking red on the battery but I'm assuming it's way to low to let charger charge it is there anything I can do?
Yeah that’s probably not even worth messing with there! Best thing to do to get them batteries charged to probably break down the whole battery pack and charge the battery cells individually and then put everything back together.. that’s just too much work if you ask me
@@pjscootermods ok yea I figured but ok thanks really appreciate u taking the time to reply bro your videos are extremely helpful. Did you expect so many people to watch em when u first started?
@@albertscroggins7977nope I sure dident! But it’s a blessing ! At one time I remember only having 2 subscribers and within 6-7 months now I’m at 2.5 k 🙏 and still growing it’s crazy !
Now I-just need -sponsorships-but everything takes time.
Thanks bro 💪
@@pjscootermods that's cool af bro keep up the work bro do you get paid for so many views or whatever? jw
@@albertscroggins7977 yeah I was surprised actually because Starting off with zero subscribers pretty much means nobody knows about your channel.
My battery voltage is so low.The whole pack have only 3.07 volts , the red light on the BMS blinks but the charger shows green and the charger charges it with only 200mA.The problem is not on the charger because I tried with another.How to fix the issue?
Sounds like it’s time for a new battery ! 🪫 if you did the BMS bypass and you’re only at 3.7 V, then your battery pack has become undervoltage and will not charge because the charging box will not detect it since it’s below 31 v . Solution for this is a battery replacement
my bird flex really took a shit on me 2 weeks ago when it decided to not charge anyone. i use it to commute to work and back since it saves me so much gas, and i tried to take the battery off but can’t seem to know how to take the cover off.. please, please can you help me out in any way.
I'm having the same problem can't get the cover off..
my charger pack light is green when not plugged in, but when plugged in to charge it turns off ? no green or red light. i have a bird flex.
What size battery and what’s the voltage?
Please make a video of how to convert the v3 to a personal pls
Its like the 2 pretty easy shit
@@modxho2292 like all the color wires?
@@dannys4831 yeah
I just got my charger today but My bird 3 has been charging for over 5 hrs and the light hasn't turned green is that normal I'm almost on to 7 hrs of it charging
Touch your charger the black box and it should be getting warm or almost hot and that should indicate that it’s almost completely done charging..
I did everything but my throttle won't work and when I unplug it while the scooter is on It run none stop!!! Is there anything I did wrong I even change the throttle it's still doing the same thing and yes I try the Two intelligent cables still no luck 😢 Help please
Your not wiring somthing right on the throttle part .. the only way I see the wheel free spinning is if your forgetting to coonect your ground -black wire- going to your throttle. If u leave out the black the wheel is going to free spin..make sure it’s not pinced somweheres along the way causing it to ground out That’ll also cause it to
Free spin. If you replaced the throttle already like you said then it doesn’t like a throttle issue
So i. Got the same scooter as you what controller am I able to get that will work with this thing can send me a link or reply with a link
Depends what you have
if you have a bird-3 then I’d go with the 500w brushless controller
If you have the bird-2 will then go with a 350 W brushless controller
@@pjscootermods can you do a short showing the differnce? I don't know what I have

bro my battery is outputting normal current but red light won’t come on and it won’t charge is the battery bad. No charging noise and the charging light stays green. Battery is at 40 volts rn. it was charging before my bms bypass
Did you ever figure out
@@Diceman361 yeah i shorted the bms at some point lol. had to get a new battery. even your sweaty palms are enough to short or trip the bms so be careful. in my experience if the red light isnt coming on or its not flashing normal the bms is broken. some people will replace the bms but its a little time consuming
Help needed. Bird 3. I bought a charger but the light remains green when plugged in. I checked the connectors at the BMS and it reads 93v going into the board. The little red LED light blinks once every 3 seconds but it is not charging. I tried the reset by jumping the RST and B- before and while charging but still the same blinking pattern. Any advise? thanks
Your reading 93v on a 36v battery pack ?
@@pjscootermods
My bad Sir, the battery pack reads 35.5v, when I plug the charger in, the reading is 43.2v going in but still, the LED light blinks every 3 secs. Does it means it is fully charged? I will put everything back together and ride it. I will update in a few days.
@@a.caballero9514 They’re supposed to be a light that blinks so that part is normal.
No worries on that part
If the light is Constant then you have a problem.
Should charge right up ! Soon as you plug into charger if it needs charging then the light will be red indicating a charge. You had said your battery is at 43 V ? The maximum voltage reading should be 42.2 V .. if that’s the case I assume your battery pack is all the way charged! And that my friend will call you like to stay green .
i had luck af because my battery only was smoking and not burning😅
same, is the battery now dead?
Yeah man that’s why I say to be careful working around all those small different components you have on the BMS.. working with electricity it’s pretty fucked up i’ll let you know what you’re doing..
Nothing on that BMS needs to be touched except for the B plus to P plus bypass that way you can get your output back..
Without the bypass your scooter is no more then much a brick!
@@pjscootermods
@@pjscootermods bro my terminals accidentally touched and now it won’t charge but it still throws voltage
What if it charges but won't keep a charge?
