One thing to ask: disconnected battery voltage was 12,3 volts. battery voltage, connected to the working bike 12.2 volts. this means only one thing, alternator on this bike is not working or missing or disconnected. Otherwise how the original lead acid battery is going to be charged? Lead acid batteries require around 13,5-14 volts DC in the electrical system of the bike or a car. Battery shown in this video is not suitable for direct replacement of the Lead Acid battery. It will fail !
How does the battery perform after years? The cells do not overcharge due to too high charging voltage? After all, the alternator generates a charging voltage of 14.5V, which is too high for 3S Liion. By the way, using a plastic bottle in this way is one of the best and smartest tricks I've seen on the net! :D I'll try that too. Thanks for video!
The 18650 lithium battery pack you inserted into the bike, does it now have the same charging source from the bike as the earlier lead acid? Thank you.
3:00 a pair of wire snips is all you need if you put the case in the freezer for a few hours. The soldering of the cross pieces could be done on the bench. If a 'ladder' dia could be used the 'steps' would be made of a 'fuse wire between two cells 9@2.5ah) that has a common wire that is a tad thicker to complete the 12v s4 20ah battery. Times that by 5, you have an e-bike you can ride for a few hours.
Nice video but, if you place a buck converter between original charging system and the battery, set the voltage to 12.4-12.6 volts it's better for the battery and the BMS.
I think he mean the output of the scooter so the voltage entering the bms is lower. But it's needs to do current both ways so I'm not sure how that would work
the scooter generates 14.4V but the BMS has a controller, and as soon as it reaches 12.6 - 12.8V it turns off the power supply to the batteries using the mosfets
nicely done. q1. don't you need thicker cables?for around 20-30 Amps? q2. is that bms capable of handling such amperage? q3 no heat sensor/alarm. what if bms fails and keeps overcharging? explosion and fire. I have yet to see any diyer in you tube to take into consideration safety and the limitations of lithium batteries. Good effort anyways.
Оnly the cables in the poles should be thick and they are 6mm² the rest of the cables are for balancing and no need for a thick cable. The BMS is 100A, the starter draws 30A and the alternator cannot exceed 5A when charging. Yes, you're right, I didn't put a thermal sensor, but I should have.
I have seen 'miracles' happen with solar lithium bats as well as 18650. Fires, explosions, bms failures, melted cables etc etc. Mind you that bms's are chinese junk. Quite unreliable and fry easily. Once they fry your only safty angel is a thermal sensor -provided it is reliable- lol. My comments have only safety in mind with the chinese unreliability variable. Keep up the good work. Tnx
nice video brother please what I would like to confirm is how many voltage is the battery each and how many do I need to put together to get that 12 volt 15 amp
Super! 2 questions: 1. how does the zinc plate (not the flattened copper wire) get on top of the cell? 2, is charging the motor good for the Lithium-Ion battery? Thank!
Those are used batteries and the flat tin is the old connection between them. The circuit board allows the alternator to charge the batteries safely. I have a spot welder to reweld the batteries together with new flat tin. Either way if fine.
Nice job, kind of weird that the cells fit so perfectly into the battery case! My personal preference is to twist wires prior to tinning which keep all the strands together and prevents any stray strands. Only other caution would be the fact everything is quite tight in there but in the use case with a very short discharge when starting and relatively low current charging it seems like a good solution 👏
I think it would be better if you properly spot welded the 18650 cells with zinc plated strips, between them. I have tinned a lot of copper wiring to cells and stuff. I don't think it is the best approach for this case, a motorcycle battery, which has to endure a lot of vibration and shaking/bumping, especially if the roads are rough in your country, because there is a much higher risk of cracking a solder joint and making a short or just killing the battery pack and your precious work, faster than you would believe. Nice job though.
@@BOB-eb8xz Not really. The bms board charges each cell up to 4.2v and stops charging omce it reaches that value or about 12.6v total. I've made a similar battery and tested this myself. Provided that he bms doesn't malfunction and everythimg goes south of course..
is it safe? have overcharge protection and short protection ? and i want to know my bike has a 12v 7a battery and my bike charging voltage come 14.9v .i have 25A (hx-3s-fl25a) bms . can i use like this battery pack without damage my rectifier
This BMS has short circuit protection and recharge protection, which interrupts charging at 12.6 ~ 12.9V. You must know, when the battery is fully charged interrupts the circuit to the battery until it starts to consume from battery.
Amazing... My question is, does the amount of charging voltage coming from the bike's charging coil affect the L(BMC) of the lithium-ion batteries... Thank you.
The voltage is around 14.4V, but the most important factor is the charging current, which should not exceed 8-10A. Which in my case is on the order of 5A
that was perfect. But my question is, can the engine charger charge this battery? 2- And this module has 5 cells. Is there any problem with charging the batteries?
All batteries are from the same type of vacuum cleaner wich I bought from the bazaar. However, the batteries are from different manufacturers, so I decided to put them parallel to the others so as not to unbalance. Otherwise, if I put them in parallel, there would be a problem with balancing maybe.
But it was not have of the same type. So I decided to put them parallel to the others. It is important that 3 × 3 are the same and you can arrange 8 rows this way. If you do not have the same batteries on hand.
For example we have 2 batteries, one with a capacity of 4Ah and the other with 2 Ah. Their total capacity is 6Ah. When connected in parallel, both batteries are discharged equally. Most current flows through the more powerful battery and there is no way to discharge the low-power battery faster because they are connected in parallel. But as you say, the best option is to have the same batteries.

I bought the batteries cheaply from damaged vacuum cleaners. When I need a 12V battery for camping, I will take it with me because it has 3 times the capacity of a lead acid battery.
@@ErCanEverything It is very difficult to convince a person who believes in BMS. But still. You need an oscilloscope, you need to disconnect the battery with the engine running, and look at the voltage waveform of the scooter's on-board network. Almost all models have voltage spikes up to 70V, they will look like needles. Interference energy is sufficient to disable bms keys. The solution is very simple - add a capacity of 10000mF * 16V to the battery terminals.
Should be charged with 12.6V, but this motorcycle charges 14.4V. but BMS protects them from overcharging, because it stops the current to the batteries as soon as it reaches 12.6 ~ 12.8V
Aconselho utilizar lifepo4 em paralelo com bancos de ultracapacitores. Esse tipo de bateria por ser carregado com tensões de 14.4 volts e combinado com os ultracapacitores pode fornecer rapidamente uma corrente alta necessário para a partida do veículo. Caso contrário a bateria seria danificada podendo explodir e provocar um incêndio.
since he refuse to answer ill answer for him. lipo doesnt have the "instant" ( punch ? ) juice the motorcycle/scooter needs. unless they changed in the last two years where i didnt read anything about that bacause it was out fo interest. i dont know what is his REAL WORLD result ( we see soemthing is fake.. he cannot charge it and we see that when the bike is running ), but normally, even 18650's doesnt have that PUNCH juice. which damage all of the 18650 cells over time ( and this time is actually short.... under 100 start ). im not an expert i just know basic facts. i wanted to do that since a long time but never did because it wont work properly. still better to change a crap brand battery every 2 year than building this.
Helal olsun Şapka Çıkardım Fakat ICR pillerin (LAPTOP dan çıkma) max desarj akımı düşük olduğu için yüksek amper çektiği için uzun vadede sorun yaşanmasın ?
its not charging tho ? to charge a 12v battery ( 12.3-12.5 to be exact ) you need MORE than that. at 12.6 it will keep it in its state ( running with NO additional load ), but to CHARGE it, it must be at least 13v. ideal is 14.0-14.7v. some OEM see peak at 15.0v but never stays there. so how do you charge it ???
hello dear sir frist thanks for this education video my question is , can we using three of this kind battery parallel together without BMS extra between them ?
Thank you very much, but I did not understand exactly what you mean. Want to use only 3 batteries in series without bms or want to add 3 more batteries to the current pack.
18650 cells need to stay balanced this is why the Bms is used if not the cells discharge and charge at different rates causing cells to fail and ultimately battery failure hope this helps
