You should never make it like that. Each battery cell has a different capacity, but in the end, it does not last long and cannot be used. I can never agree to make it this way.
he's testing it in a very cautious way, you think he does not know what you know, besides this is the first video where i see a clean indian fingers nails lol
Жжете... Это ж колхозники им это не нужно... Главное из отходов типа собрать конфетку и втюхать Лоху. А там уже не важно что это не будет работать уже через день.
You could do it from rejected laptop batts. Most of such batts are good but main problem is max current drain. Laptop batteries has max current limit, mostly 4-5 Amps. So , big capacity but low current load is the problem is practice. BMS has current limit much bigger that the batts! That could result batts to explode. For low current rigs it could be ok.
The laptop battery need to be tested before used in other configuration , because they can have various capacity ! If one have 500mAh and other 2000mAh the bms stop entier pack wen first battery ritch 2.5v ...
cool man, i got the info i needed from this video, thanks, big time At 4:09 , not a good idea. It is better to pre-solder the wire ends, and the area on the circuit board, then solder the wire to the board, the reason why, having heat on the board to long will cause that contact surface to separate from the board. plus if the wire end is not saturated with solder could cause problems. I mean it wont happen every time, but, why take the chance when it can be fully avoided.
I want wood to be my battery… could my board be the battery… if you’re doing sorcery than I’m gonna figure something else out… I’m with the fellas who use the same capacity cells on this one. Nice tools and handwork though.
Great idea to use 5V PSU with diodes and volt/amp meter to do a "short-cut" method for higher current charging. It could overcharge the batteries (4.3v instead of 4.2v) but if monitored properly it can work
If they are in same voltage rate ..it ok ....all batteries in parallel have same voltages and can't discharged different..event have different capacities because voltage remain same.....but in series it could limit capacity of power
What about capacity of each cell? Even new ones, if they are different models, cannot be used together. Also, being used cells, each should have a fuse, in case they become "power consumer" - so if they short internally, they will draw a ton of current and the fuse will pop. And for limiting the current, these are not high drain cells.
Lithium battery is dangerous. They require balanced charging in the correct voltage on each single cell. These should never be made. Making one of these battery pack can shock you if you connect them in series and if it caught on fire it’s hard to distinguish.
Hi your videos are always inspiring. Can you make a video on how to integrate a secondary hv battery in an EV let's say of half the fixed battery and switching from one battery to another to extend range in an EV.. Also what to keep in mind while choosing configuration for the secondary battery. Like should it have same voltage or current as the fixed battery for range extension.
idea : try connecting these 2 in series (set 1) and make another 2 in series (set 2) connect (set 1) and (set 2) in parallel = 24v 2000watt then make a mini electric vehicle. Which can atleast take load of 1person (i am expecting a load of 4person)
do not charge at 13.6 volts. Basically, the maximum charging current is 12.6 volts, in the case of a 3s system. But if you want to use it for a long time, charge it with a voltage of 12.2v.
this is terribly unsafe. never tested anything but voltage on the cells and didnt even bother to mark them to balance each array. youre going to end up with burned out cells all over the place. Good job teaching people how to be incredibly unsafe with high current.
Agree. This method does the job ONLY by matching the same type of 18650 battery or with identical mAh. Having 5000 mAh and the other side is 2850mAh is ridiculously unsafe to mix. When charging the cells, the 2850 may degrade easily plus ka-boom!
Jede einzelne Zelle muss auf Kapazität, Innenwiderstand (bei hohen Lastströmen) und Selbstentladung vor einer Wiederverwendung besonders in Packs untersucht werden... andernfalls ist der Pack schnell entladen!
Một sự sai sót lớn khi đóng pin cũ là không đo nội trở và test dung lượng , cân bằng pin đúng cách thì đừng mong pin của bạn bền được . Tôi thề là không đến 2-3 tháng pin của bạn sẽ chết hết 🙂
Mr electron, I need your help to design a electrical and electronics circuit, which could be a game changer in ev vehicles. How to connect with you sir
If we assume that we collected a number of lithium batteries in series or in parallel, what is the electronic circuit or method that should be connected to this group so that the voltage does not fall from the minimum permissible limit, meaning when we withdraw the voltage from the battery to a minimum, the circuit automatically disconnects the current? How do we determine the circuit voltage and amp? thanks
Полное отсутствие знания что ты хочешь собрать, или пожарный ящик или хороший АКБ, не советую брать за основу это видео. Все элементы 18650 надо сначала проверить на емкость и ток само разряда, они ведь б/у. А НЕПРАВИЛЬНОЕ ВИДЕО СМОТРЕТЬ СМЫСЛ НЕТ.
Vue le nombre d'accumulateur on se demande si il est préférable de pincer ou souder les éléments de la batterie pour la contrôler si il est préférable des séries de trois toutes en parallèles avec un coupe circuit sur chaque parallèles en cas de décharge profonde le tout avec une bonne dose de courage
Your video was nice and ideas was cool aslo ,so may I requested to kindly Please make DIY BMS lithium battery charger. It's important part how to charge lithium battery ,that why requested to you please make "DIY BMS lithium battery charger."easy and simple
No. The starter motor requires high current. Generally 1 cold cranking amp (CCA) per cubic inch of displacement. i.e. a 2 liter engine (120cu.inch) will require 120 CCA to start. Diesel engines require double this.
So could I connect a 3000 watt 40 amp sine wave inverter to that power control board be able to charge with solar panels and use the inverter to power like a space heater and other stuff like a forced air heater? Would that battery pack assembled like that connected to a 3000 Whataburger be able to handle the starting wattage and running wattage for a forced air heater?

Internal resistance increases of old batteries even voltages the same. Load testing needed.
I gotta say it. This video shows the way how 'not to solder'.
Устройство конечно нужное, но защита не помешает! Литий опасная штука, если возгорание будет!
Литий бывает возгорается без термодатчиков. В случае короткого банки пожар гарантирован
Ты конечно молодец, но предварительно залуженные провода\выводы паять значительно проще...
И на такую сборку он поставил бмс на 40а. Под нагрузкой выгорит моментально. Все эти бмски китайские смело на 2 делить можно.
Только хотел написать, какая нахрен 1кВт мощность, если вмs на 40а😂, даже если представим что она на реальные 40а.

There needs to be space in between each battery and you need to have fused connections

Have you ever tried to use only the flux in your solder wire? That flux you use is for tubes, not for electronics! To watching this is terrible.
Dude 2 series connections is NOT enough if you ever plan on pulling anywhere near 1000W. Even 100W!

Can we use it as a standard bike battery

What about battery and impedance matching to avoid making a bomb???
Такой ток на такой промежуток времени может выдать даже одна не высокотоковая банка 18650, что в этом удивительного?
