Huuumwah, you are a great man, thanks a lot for the fabulous course. Since i was looking for how to connect the balance socket. It's exactly like connecting a BMS. God bless you 'n gives you more than you wait.
It would be better for others to learn and understand what you said. The diagram on how you arrange the battery parallel. Most of the beginners will confuse serial and parallel connections. Thank you
Thanks for a well explained video. One question: should you really connect both the "old" charging cable and the balance cable? Or does the balance cable only measure voltage?
With the "4 button" chargers, you can change battery type from LiPo to Lion or LiFe by toggling into the Program mode and changing the type. Be careful
I built a duo 6s cradle system each wired in series. Then I heard about parallel charging and that bothered me. This helped confirm that my wiring is correct so I should be able to plug it in without blowing something. I did blow a cheap charger a while back getting it wrong! I also didn't think about using 2s, 3s, etc cables instead of a 7 pin. That makes sense as the charger rotates from pin to pin (cell2cell). So thank you again my friend.
With 6s6p if it isn't overkill. You can start car and most likely not need to disconnect because it can handle the highest alternator voltage. Stop and go every day for a week and then take it into house to put all the cells back into balance. Drill a hole into the cab and attach it inside car so you do not have to always put up the hood.
The reason that I am looking at your video is that I was given a new Ryobi 18v 4 amp-hour battery which was not working. Disassembly showed all ten cells were at about 3.8 volts and hence OK. My plan therefore was to look for disconnects on the control circuitry and if nothing was obvious remove the board and wire the batteries directly. I have an Accucell 6 Turnigy charger like you and tried to charge the battery as a complete block. The unit would not do it and gave the error message ‘balance charge connection’ despite it not being in the balanced charge mode. This is the second battery on which this has occurred and I think that the software has been programmed to do this. I am interested that yours will, but wonder if you have actually tried it. What I can do is charge linked pairs of batteries, but this means five episodes of charging to get them all up to level. Batteries all have an internal resistance which is more matched on more expensive batteries. On cheaper batteries this may lead to problems. Watching your video I will reattach balancing cables and try again, but whilst thinking about it remembered that you can buy tiny voltmeters to go on the balance cable for a few dollars and so one can monitor the power tool to ensure that the batteries are not discharged too far. Hobbyking certainly sell these for the model aircraft guys. I have also chopped a drill battery case and put in a Turnigy 18v cell to get my old Nicad tools working again. These batteries tend to be 2/3 of the price of the main tool companies. I was also able to resurrect and 40 volt Hilti drill for a friend with two 50 buck batteries joined and convert it from nicad to lithium. They are easy to charge on the Accucell charger. He was told that he must buy a new drill at almost 900 bucks. 12 volt kit can be done in the same way. Thanks for the video
Do you know anything about ego 56 volt batteries for leaf blower and lawn mower they're all compatible 56 volt anyways I'm trying to make one that will work with it not having the original battery but there is two wires that I found out or something about communicating or temperature wires so there's no way to make it after market battery that I've been able to find so far is this true how can I bypass this communication wire anyway??? The brand is called EGO , I think there's somewhat new or newer company but I'm not going to drop $400 or $500 on a battery that's crazy I got the leaf blower for free I just need a battery cheers if you can reply
Hello Vuaco, I have some favorite smaller power tools (power screwdrivers etc.) that are 7.2v. By watching your videos I have replaced the old Ni-Cd batteries (usually 6 short "C" batteries) with two 18650 cells and they fit perfectly.....My question is, when two 18650 cells are used together to power a 7.2v tool, Is it considered a 2 cell pack and should it be balanced charged? The newer high voltage tools have many 18650s so is each one considered a "Cell"? Or should I consider every pair a "Cell"? All your videos are packed with lots of info and I would not even consider re-building any battery packs until finding and watching your channel...I have re-built packs for family and friends in the past months and they think its magic! Lol Thank you for sharing all your knowledge with the world and especially me in Canada :)
Yes, a 7.2V with 2x 18650 is considered a 2 cell pack and should be balance charged. You can get away with a few cycles by not charging it to full 8.4V but eventually you will still need to balance charge it.
@@vuaeco Excellent!! Thank you very much for taking the time out for my questions. I haven't had such great customer service for a long time. I will make a donation to your Paypal or Patrion account for your next smart charger or project, Its well worth it :)
Thanks for this, I was told last year it doesnt matter on these types of batteries about balancing but I have doubts now so I looked for a video like this. Always get a second opinion I guess.
the balancing is in the charger through the pins to the "balanced" wiring. If you are using a 2-5 amp brick type charger with a single ground and single positive a BMS IS needed to take care of the balancing. It distributes the amperage to about a half amp (usually) up to 1 or 1.5. It's best to go by the mfgrs spec if you know it.
Great video thank you very much so what about my battery homemade pack has 39 18650 cells so would i have to buy a connector with 39 wires on it ? Do they even make Chargers with connectors that big ? or do I break it down and do it in groups of six even though they're connected to do the balance???
No offense sir but your accent is unique. Are you Asian from Oklahoma? Anyway, great job on these videos very informative and precise. I really like the way you present each video. And how you do things like me (on the cheap). I have a question, I built a 3s4p pack with fuse wire. After I built it, I checked it with my multi meter and the reading was 11.7v. I then connected a 400 watt inverter to it. I ran a load of 27 watts for around half hour. Then the alarm of the inverter began to sound off. After disconnecting it from the pack the voltage read 3.2v. How is this possible? Please guide me to the right path. By the way I didn't use a BMS or hooked up a balance lead like you. I'm still waiting for my imax 6 from China. Thanks. Mario
Is it 3.2V each or 3.2V total? (you have 3 in series?) Depends on what kind of inverter you have, most will have a low voltage cut off about 11V. You can use a volt meter hooked up to your inverter and run it under load and monitor where exactly it cuts off. I'm from California, Asian, yes, but my accent is kind of messed up because I watch too much British and Australian television! :D
vuaeco Thank you for swift reply..Lol...it's all good brother. Yeah, I think your right about the inverter cutting off at 11v, but I don't understand why my full pack is reading 3.0. I built this pack as a practice one. Planning on doing 3packs of 18p3s 12.6 volts for a portable power bank. What do you suggest?
A 3S Li ion pack nominal voltage (average) is 11.1V (3.7 x3). So your inverter might cut off prematurely when your battery pack still has plenty of juice. If you're brave enough, try 4S Li ion pack. They are designed to run on lead acid batteries so they can run at 14.5V comfortably. Some inverter can handle up to 16V DC though some will burn out. Try at your own risk though :)
Just say it once and let slower learners rewind the video if they missed something. It is actually more confusing when you keep repeating everything so many times.
@Solutions Architect I do watch most videos at 2X speed, but that doesn't help to rid consistent repetition. It has nothing to do with "patience". I am highly intuitive, so I grasp new things very quickly, unless there are many distractions. Like constant repetition, or when people talk too slowly. The fact that you blindly assume you have higher technical aptitude than a random person on the internet, of whom you know nothing about, makes me think that you most likely do not. Your comment doesn't seem very logical and strong logic (coupled with strong intuition) goes a long way in being jack of all trades. Which demands a high level of technical aptitude.
Great if you could see the screen on the charger I still don't know what mode to charge my 3S 8P 12 volts 32 amp 21700 cells I have lipo lilo life lihv which one is for lithium
Not sure what you meant but I’ve wired mine the positive first then alternate negative just trying the turnigy accucell 6 out to balance and my cells seem quite close already and I don’t use bms at moment some people just use bms to balance but don’t connect main power through bms one I had stopped anyway after not long on bike so I took bms off
This is grate! But in thia configuration isn't it balancing for 2 cells? Co if one in pair is weaker it will still charge the other one more then it supposed to be charged?
@@westinthewest thanks. What would. Happen if one in pair was able to be charged lower then the other one because it wpuld. Be a damaged cell. What would be the reading on that pair?
@@michatrejgis2188 It's impossible for the two cells to have different voltages. Connecting them together in parallel is the same as extracting the materials from the inside of each cylinder and putting them all together in one bigger cylindrical can, making one bigger cell.
@@michatrejgis2188 I don't fully understand the question. The two paralleled cells will both charge to the full 4.20V together as if they were one cell. There will be plenty of internet resources which will explain the principle better than I can.
This is probably very simple, but doesn't your Turnigy charger balance charge on the 7pin connector alone? was there any need to plug in your XT-60 connector?
A PCM (Protection Circuit Module) is to prevent over charging and over discharging. You don't really need to protect over charging as the Accucell 6 or Imax B6 already has overcharging protection. You might need to protect it from over discharging when you use it on your power device. But I don't think you need that, in my opinion. Adding a PCM will make your DIY pack more costly. It also add in more complications to your build. And it also cost you more time to build. These problems will escalate when you build many of these packs to string them together to make a bigger pack. What I do is I just use a voltage display monitor so that I know exactly the voltage of my pack at any time and unplug it when it is necessary. A 4.2V cell will be flat at around 3.5V to 3.7V. You don't want it to go any lower as it will damage the cell. Plus, a PCM will not likely to help you at all. Just look at the Ryobi power tool 18V battery pack. I did make a repair video on that and it turned out the Ryobi PCM board did nothing to protect the pack from over discharging. Sadly, Ryobi is not the only manufacturer that fails on this. Many other power tool batteries fail just because they are over discharged even though they all have PCM onboard. Here's the link to the Ryobi battery repair video if you want to see it: ruclips.net/video/wEzCO-DIMoI/видео.html
Thanks a lot for this video. Maybe someone can help me out with a problem I'm facing for hours now. I've two Accucel-6 and they work with packs without any problem. Now I want to use them for an ebike. I ordered a bunch of NCR18650BD Lion. I've put them in 3S with different numbers of P. The load current seems to be limited to 1.0 A, independent of all settings. For 1P it may be ok, but for e.g. 14P it would take forever to load the set. Any comment? thanks
solved. I've introduced it myself. On both ends of the battery I've put copper tape to improve the connectivity. But the opposite happens. It added a small but important resistor to the lines.
Depends on how much Amps you set on your charger. I usually charge 1A per cell so for a 2P pack, I set 2 Amps charge. That usually takes about 1.5 hours from completely empty to full.
Why you charge at lipo program and not li-ion? I always have this question.also i just build a 3s battery pack with total 12 batteries 4+4+4 .my question is what would be my minimum voltage to stop using the pack?Also i have a pcb ready to solder it .should i? Or i am good without?
Because there is no such thing as a "LiPo" program. Both Lithium Ion and Lithium Ion Polymer (incorrectly termed "Lithium Polymer" or "LiPo" for short) share the same set of possible chemistries (because they are in fact the same other than what they use for their outer shell) and can have (depending on the chemistry used) a charge voltage from 4.1 to 4.35 volts.
Where the batteries Lipo or Li ion? I noticed you chose Lipo for the charge but the batteries look like Lion. I am new to this so forgive me if got that wrong. Ken
Please help, ty for the video but I made a 4p battery pack for my 3.7v fish aerator, my question is does it need a balance wire for the 4 parallel 18650? Im a nebie and cant find anything on parallel balancing. I own a battery new spot welder and skyrc b6 charger. Any help will do, thank you.
Hi Max, you don't need to balance charge a 4P pack because every cell is balanced to the other cells connecting parallel to it. You only need balance charging when your pack is connected in series with 2S or more..
can those small charger used to charge larger batery pack like 6 series of 10 parallel battery? so total is 60 battery? or any sugestion what charger best for 60 battery cell for electric bike
Hi! Can you please show a balancing charge on an 18V Li ion Makita battery, without opening it up, just using metal flat sticks to connect to the battery. Thanks!
Good day. My 4s balance wires have 1 red and 4 black. How would I connect those? Isn't red positive and black negative? You are connecting to negative the rest of cables to positive of cells. I'm confused...
The colors on the balance wires are usually random. At least that's what I have. Don't use the wire colors. Just follow the instruction on the video and you should be fine.
hi how come tommy calloway wires balance wires 1st wire positive then alternative negatives but you wire the opposite way round 1st wire negative then alternate positives.im confused which way do I wire ?
He probably just flips that connector the other way around. As far as alternate positive or alternate negative, it's the same thing. That's because the connection is series so positive and negative of the 2 adjacent batteries are connected together.
hi my bms 4s come for my battery 12v 4s it has multi coloured balanced leads but I have red /black balanced leads they usually go first red to positive then alternate black to negative of cells don't they?steve
Usually. And yes, you can do first red to positive and then alternate black to negative cells. It can only go in one way, though. But what I have seen from these balance leads is that they have no specific color codes. They seem just to have random colors.
hi vuaeco.im watching one of these accucell chargers ebay will it charge my 6s5p packs and balance at same time?im using 6s2p x2 and a 2p to make 14s5p kit 48v for ebike
You can. But you have to make sure they all have isolated grounds or they will short out. And it will also take you a lot of time every time you have to charge the battery pack though.
If you only have 3 sets of 4 in parallel, it's a 3S4P pack. You cannot have 4 in series with 3 sets of 4 in parallel. But anyway, you can still balance-charge your pack when you have series/parallel in your pack. The principle is still the same. Just regard your parallel batteries as one giant cell. For example, if you have 3S4P that means you have 3 in series and 4 in parallel . Just consider it as a 3S pack with each cell 4 times the capacity as a regular pack. So the balance charging procedure is still the same as a 3S battery pack. And you can put the balance lead anywhere along each of the 4P.
@@vuaeco hi, a quetion if i want make a 2S2P or 2S3P, 3S3P, how to balance the battery in parallel? dont have problem/explosion if parallel cell aren't balance? i can use 26650 battery for more mah?
CAUTION This is total nonsense - you are balancing cell pairs with other cell pairs, you are NOT balancing all the individual cells: To that you would have to isolate or separate cell pairs into each individual cell, not coupled together in pairs as in the video. Sorry but if you don't know what you're doing, don't publish videos unless you say what your limits are.
@@vuaeco Right, let's get this straight so people don't waste their time: If you are balancing cells it's for a reason. If you want to balance a series of cell PAIRS then this video is for you. But it is obvious that balancing the SERIES of pairs is important to you - so you must be doing it for a reason - presumably that you think there is a need to balance the entire battery properly. So what's the point if you don't balance each cell-pair before balancing the series? You could have a bad cell or a failing cell in any of the pairs. Sorry but the video is a waste of time unless you check and balance all cells. If you live on the assumption that batteries don't need balancing (i.e. each cell) then why balance any at all - simply don't bother. If you want to play with lithium batteries, it's good to know what you are doing - bad batteries can cause fire or explode when overcharged or wrongly charged. Again I say CAUTION to your viewers and would urge you to correct your video instead of being rude.
@@gurglejug627 Hey, in case you know the issue. I have an electric scooter ( gotrax glider) with lithium ion batteries. It turns off unexpectedly, sometimes when I hit a bump, sometimes when I go fast or slow at certain time. Bar shows full charge. After fully charging (it sometimes struggle to charge). After shutting off, It wont turn on unless I charge it and then disconnect. Full is 28v and minimum is 24v. When it turns off unexpectedly. The voltage shows 16v (from motherboard) do you think the battery is defective and can It be fixed? The company don't sell battery pack for that model
@@LemonJuiceGV Sorry I know nothing about those - could even be a variety of factors, control board, sensors, bad connection etc. Best bet is probably a radio control club near you who might have some electronics people there. Hope you can get it sorted.

A PCM (Protection Circuit Module) is to prevent over charging and over discharging. You don't really need to protect over charging as the Accucell 6 or Imax B6 already has overcharging protection. You might need to protect it from over discharging when you use it on your power device. But I don't think you need that, in my opinion. Adding a PCM will make your DIY pack more costly. It also add in more complications to your build. And it also cost you more time to build. These problems will escalate when you build many of these packs to string them together to make a bigger pack. What I do is I just use a voltage display monitor so that I know exactly the voltage of my pack at any time and unplug it when it is necessary. A 4.2V cell will be flat at around 3.5V to 3.7V. You don't want it to go any lower as it will damage the cell.
Plus, a PCM will not likely to help you at all. Just look at the Ryobi power tool 18V battery pack. I did make a repair video on that and it turned out the Ryobi PCM board did nothing to protect the pack from over discharging. Sadly, Ryobi is not the only manufacturer that fails on this. Many other power tool batteries fail just because they are over discharged even though they all have PCM onboard. Here's the link to the Ryobi battery repair video if you want to see it: ruclips.net/video/wEzCO-DIMoI/видео.html
We need a slower phase video, but gets the work done..
I am having trouble locating the balancing cable plugs. Where do I get those?
This was 5 years ago but I just bought some from Amazon and the wires are a little short plus the wire gauge is thinner than I would like.
Thanks a lot for this video. Maybe someone can help me out with a problem I'm facing for hours now. I've two Accucel-6 and they work with packs without any problem. Now I want to use them for an ebike. I ordered a bunch of NCR18650BD Lion. I've put them in 3S with different numbers of P. The load current seems to be limited to 1.0 A, independent of all settings. For 1P it may be ok, but for e.g. 14P it would take forever to load the set. Any comment? thanks
solved. I've introduced it myself. On both ends of the battery I've put copper tape to improve the connectivity. But the opposite happens. It added a small but important resistor to the lines.
Thank for ur video sir can i know how much time it take to charge the packs
Depends on how much Amps you set on your charger. I usually charge 1A per cell so for a 2P pack, I set 2 Amps charge. That usually takes about 1.5 hours from completely empty to full.
Why you charge at lipo program and not li-ion? I always have this question.also i just build a 3s battery pack with total 12 batteries 4+4+4 .my question is what would be my minimum voltage to stop using the pack?Also i have a pcb ready to solder it .should i? Or i am good without?
Because there is no such thing as a "LiPo" program. Both Lithium Ion and Lithium Ion Polymer (incorrectly termed "Lithium Polymer" or "LiPo" for short) share the same set of possible chemistries (because they are in fact the same other than what they use for their outer shell) and can have (depending on the chemistry used) a charge voltage from 4.1 to 4.35 volts.
Where the batteries Lipo or Li ion? I noticed you chose Lipo for the charge but the batteries look like Lion. I am new to this so forgive me if got that wrong. Ken
They both have the same charging parameters.
Do I need to soldering that cabels if I use bms on my 3s bat.pack and charging with imax b6 mini? Thanx
Thanks
Please help, ty for the video but I made a 4p battery pack for my 3.7v fish aerator, my question is does it need a balance wire for the 4 parallel 18650? Im a nebie and cant find anything on parallel balancing. I own a battery new spot welder and skyrc b6 charger. Any help will do, thank you.
Hi Max, you don't need to balance charge a 4P pack because every cell is balanced to the other cells connecting parallel to it. You only need balance charging when your pack is connected in series with 2S or more..
@@vuaeco oh! ok......TY so much.
3:12 if them cells are really killed, it won't charge atall
Sir what if you have bms on your battery pack. Do i have to balance the battery pack or just charge it
Just charge, BMS takes care of balance
Do you really have to choose the proper program before you attach the battery connections?
No. You can program before or after connecting to a battery pack.
excellent explanation, what if you have more than 6s
use 2 charger
can those small charger used to charge larger batery pack like 6 series of 10 parallel battery? so total is 60 battery? or any sugestion what charger best for 60 battery cell for electric bike
It can. But max current is only 6A.
Hi!
Can you please show a balancing charge on an 18V Li ion Makita battery, without opening it up, just using metal flat sticks to connect to the battery. Thanks!
Makita batteries have a balance built in so connect it to a charge. Pick charge option, away you go.
@@johnlever6696 indeed, away he goes

if u could answer this question: what if i have more than 6 batteries to balance? if yes, how do i balance it with this imax?
This can only do 6. If you have more than 6, you'll need to separate them or get a BMS and a dedicated charger.
@@vuaeco do u have a messaging app like whatapp or telegram, i like to know how to do it
Good day. My 4s balance wires have 1 red and 4 black. How would I connect those? Isn't red positive and black negative? You are connecting to negative the rest of cables to positive of cells. I'm confused...
The colors on the balance wires are usually random. At least that's what I have. Don't use the wire colors. Just follow the instruction on the video and you should be fine.
vuaeco I'm gonna give it a go. Thanks for all your input.
i made a 14 cell battery pack out of 18650 4000mAh 3.7v li-ion battery and i would like to how to balance charge this 14 battery pack can help me
Where can I get batteries balance charger in Kenya pls
hi how come tommy calloway wires balance wires 1st wire positive then alternative negatives but you wire the opposite way round 1st wire negative then alternate positives.im confused which way do I wire ?
He probably just flips that connector the other way around. As far as alternate positive or alternate negative, it's the same thing. That's because the connection is series so positive and negative of the 2 adjacent batteries are connected together.
hi my bms 4s come for my battery 12v 4s it has multi coloured balanced leads but I have red /black balanced leads they usually go first red to positive then alternate black to negative of cells don't they?steve
Usually. And yes, you can do first red to positive and then alternate black to negative cells. It can only go in one way, though. But what I have seen from these balance leads is that they have no specific color codes. They seem just to have random colors.
Ones i got online are THIN. little scary 😮
Thank you.
Was looking for the part number for that Balance Connector/wires. Anyone have this information?
My advice to anyone use heavy balance leads dont skimp on $$$ heavy wires Little insurance on shorts😮
hi vuaeco.im watching one of these accucell chargers ebay will it charge my 6s5p packs and balance at same time?im using 6s2p x2 and a 2p to make 14s5p kit 48v for ebike
Yes, it will charge and balance a 6S pack. You can get an 8S charger but it's much more expensive.
u should chasnge it ti li-ion not li-po will do a lot better job at toping off and maintaining battery
Can't you just tap out the 7 points and charge it at 3.7 volts isolated without using the hobby charger?
You can. But you have to make sure they all have isolated grounds or they will short out. And it will also take you a lot of time every time you have to charge the battery pack though.
@@vuaeco ok. I will be charging them only one at a time to reach 4.2V target.
What about 13s13p battery pack? How to balance those packs?
Here's the video that might answer your question: ruclips.net/video/E2laf30KYyU/видео.html
how would you wire up the balance charging if you make a 2 or 3 cell battery but in each cell in 4 18650's?
You mean a battery pack of 2S4P?
vuaeco it would be 4 batteries in series, and 3 sets of 4 in parallel
If you only have 3 sets of 4 in parallel, it's a 3S4P pack. You cannot have 4 in series with 3 sets of 4 in parallel. But anyway, you can still balance-charge your pack when you have series/parallel in your pack. The principle is still the same. Just regard your parallel batteries as one giant cell. For example, if you have 3S4P that means you have 3 in series and 4 in parallel . Just consider it as a 3S pack with each cell 4 times the capacity as a regular pack. So the balance charging procedure is still the same as a 3S battery pack. And you can put the balance lead anywhere along each of the 4P.
@@vuaeco hi, a quetion if i want make a 2S2P or 2S3P, 3S3P, how to balance the battery in parallel? dont have problem/explosion if parallel cell aren't balance? i can use 26650 battery for more mah?
This was supposed to be a charging without the balance cable and at the end of video you plug in balancer, what the hell?
I should be the one who asks you that question, mate.
You need to balance the sound for this video.
I thought I was going mad.
@@johnlever6696 No, not mad, sarcastic :-)
ROBERT FRIEND yeah but the sound was bouncing from ear to ear. Felt weird.
@@johnlever6696 Not good for ears and amateur recording. I don't watch any video with amateur sound.
Larger batteries need to be of the plate type. Not AA. (double a)
Charging liIon batterys in LiPo mode? Wtf...
Do some research before you troll.
@@vuaeco why "troll" if u wann tell me that liion and lipo batterys are the same thing you dont need to wonder when your batterys dont last very long
You should choose li io option on the charger lipo cells are 3,7V li io cells are 3,6. I have the same charger it can work in liio mode.
Buk Lau is dat a yuuuuuuuuuu
Yes, it's me when I'm not swearing.
top vid tho bro :)

CAUTION This is total nonsense - you are balancing cell pairs with other cell pairs, you are NOT balancing all the individual cells: To that you would have to isolate or separate cell pairs into each individual cell, not coupled together in pairs as in the video. Sorry but if you don't know what you're doing, don't publish videos unless you say what your limits are.
LOL! If you want to be a clown, join a circus.
@@vuaeco Right, let's get this straight so people don't waste their time: If you are balancing cells it's for a reason. If you want to balance a series of cell PAIRS then this video is for you. But it is obvious that balancing the SERIES of pairs is important to you - so you must be doing it for a reason - presumably that you think there is a need to balance the entire battery properly. So what's the point if you don't balance each cell-pair before balancing the series? You could have a bad cell or a failing cell in any of the pairs. Sorry but the video is a waste of time unless you check and balance all cells. If you live on the assumption that batteries don't need balancing (i.e. each cell) then why balance any at all - simply don't bother. If you want to play with lithium batteries, it's good to know what you are doing - bad batteries can cause fire or explode when overcharged or wrongly charged. Again I say CAUTION to your viewers and would urge you to correct your video instead of being rude.
@@gurglejug627 Nah. I'm not gonna feed the trolls.
@@gurglejug627 Hey, in case you know the issue. I have an electric scooter ( gotrax glider) with lithium ion batteries. It turns off unexpectedly, sometimes when I hit a bump, sometimes when I go fast or slow at certain time. Bar shows full charge. After fully charging (it sometimes struggle to charge). After shutting off, It wont turn on unless I charge it and then disconnect. Full is 28v and minimum is 24v. When it turns off unexpectedly. The voltage shows 16v (from motherboard) do you think the battery is defective and can It be fixed? The company don't sell battery pack for that model
@@LemonJuiceGV Sorry I know nothing about those - could even be a variety of factors, control board, sensors, bad connection etc. Best bet is probably a radio control club near you who might have some electronics people there. Hope you can get it sorted.
