The last method is a perfectly safe method for charging any battery.May it be Lithium or Nickel Cadmium
How much voltage have to set as charging voltage for charge a 12volt 18650 battery pack?
@@mohammadmoinuddin582 for 3s lipo packs its 12.8v (3x4.2v) 4.2v is the maximum a 18650 can take. but u need! a balancing function. 4.0v+4.1v+4.4v=12.8v so you would destroy 1series of the battery pack. google "3s" "4s" and "bms". it will answer a few questions i think.
i know Im pretty off topic but do anybody know a good place to watch newly released tv shows online ?
@Timothy Evan Try Flixzone. You can find it by googling =)
@Graham Javion yea, have been watching on FlixZone for months myself :)
Gracias por compartir tus proyectos saludos desde Argentina
Bu bilgiler çok iyi teşekkürler
I almost had a heart attack when you connected those 18650s directly to the lead acid battery
Me too
Me too! Haha
What the heck I have watched!?
I connect positive to positive & negative to negative. After a couple hours it's charged. Maybe I've been lucky but I do this all the time. I will feel for heat 1/2 way but haven't encountered a problem.
I think you must be needed to use bms for lithium or lion type batterys
C'est excellent merci pour l'explication
A cc cv dc converter is much better, if you do not have a dedicated charger, it is best to charge to between 3.7 and 3.9v when using non current regulated converters or power supplies, and supervise the remaining charge, to prevent damage or fire, also for longer battery life! lithium is awesome but can be dangerous! Great video,
Can you show the link for board with voltage and ampere indicator! I can't find from description!
I have a e-bike battery it’s lithium ion it has 36 cells in it they’re packed in groups of six I believe one of the groups of six got disconnected, the weld connection broke so that group of six is lower voltage than the rest now the entire thing won't charge can I simply just re-weld it to the rest of them and charge it back up to normal or do I have to take them out separately to charge them up fully to match and then reconnect them??
Very good 👍
Thank you
You did not understand the operation and charging method of a lithium battery. You should not charge over 4.2 volts and should maintain a maximum current depending on the lithium cell. All shown charging methods are not suitable for charging a lithium cell. Method 1 is a (very dangerous) short circuit of the cell. Method 2 has no voltage limit and the charging current is dependent on the bulb. Method 3 is also a waste of energy (12V -> 19V -> 4.2V). Why you don´t use a TP4056 module? This has at least a charge control and charging switch-off. Or at least a DC-DC converter with adjustable current limit? This is not recommended for imitation.
3:27 "now comes the advanced and proper methode" Whahahahahaaaaa!
If it Possible to make another Video with a Separate Amp Meter !!!
and separate Volt meter
THANK YOU SO MUCH FOR YOUR VELUBEL INFORMATION 🙏🙏
whats so valuable about showing someone how to charge a battery with a battery chargine module.
dumbo
Charging requires CC and CV with a limit of 4.20 V and 1A. (Dependent on the battery) connecting to a 12V battery can overcharge and there is no regulated current limit which could cause the batteries to umm well... Boom. Or Fire.
Yours videos are so nice please tell about solar panels
yeah ,very very nice,
Can you use the charge bord for a car 12v battery ?
Mr electron...it possible to use my 42v 2A charger to my 48v lithium battery?...thanks for your answer
Sir, can we charge 12v lithium ion batteries (series) with that
module..??
This is good. You showed how to control the current by lowering the potential difference.
I hope you have a good fire insurance for your house, one that covers stupidity
@@Michel-7.7.7 i dont get it. How is admiring content that shows some educational values has anything to do with my house?
@@kongyihfann5546 if you follow his hazardous "tutorial" and Charge your li-ion batteries with a 12v car battery, you have a good Chance to burn your hpuse
@@Michel-7.7.7 @Michael Justen but my comment has no single word asking you to do this but compliment how the concept of charging / current flow vs voltage concept is shown.
And thanks for relating that to my house and intellect
@@kongyihfann5546 i'm sorry if you were somehow offended about the fire insurance joke. I wasn't questioning your intelligence at all, not everyone is an electro engineer, including me and obviously this guy. If you want to teach something, you have a responsibility, so at least call Method 1 a Fire time bomb
I like the video, the reason charging cells like that without a BMS is dangerous, is because the cells can become over-voltage and explode. The batteries will attempt to pull as much amperage as their internal resistance allows, which is generally more than 10 amps for each cell. This is why large battery packs heat up when charging. Resistors for each cell must be used.
Can we use XM-H604 module for charging 18650 battery pack safely ?
@@chamunu123 That depends. Charging a 3s means 3 cells in series. The problem is one or more cells may become over or under-voltage. It could be catastrophic or just crappy, it depends on the use of a BMS. No BMS = explosion, BMS = crappy. If you don't want crappy, each cell must be charged individually using 4.15 vdc. It appears the voltage range for an 18650 is 2.8v to 4.0v.
@@Mystic-H That is an old comment. Each cell does not pull 10 amps, generally it is 0.7 amps for normal cells 18650, and 2 amps for samsung 30Q. I don't know about jump starting your battery. You could try applying charging voltage to the output. I use relays to build a custom battery that I can disconnect the series connection with. If you charge each cell one at a time, you can just attach leads without disconnecting the series connection. The problem arises when multiple cells in series are charged, as it shorts the charger, assuming you have a single voltage source.
Always use BMS before messing with these cells
first of all he should mess with knowledge
No Battery protection board is necessary between the converter and the batts ?
i think i’m going to modify my 12v makita battery charger and then charge mine 3 at a time or you know what i mean
Can i charge a bunch of 18650 pack (5-10) with mobile adapter with this booster board???
Why even show the wrong way it'll just fail ....ya cheap multimeter would be more accurate than that junk volt/amp display that's why ya need cc/cv charger with cut off at 4.2
Hello
A proper ampage n voltage charger with cut out is needed or it will over charge ..llithium batteries ether get damage or might can explode....well I know i tried long ago made hundreds of different projects
Would that work on 110 input with 12 volt output to throttle it down and this guy is not going to burn nothing. He knows exactly what he's doing I wish you were my neighbor thanks
I have a three pack of 3.7 set up in a parallel circuit which produces over 9v of electricity. How do I charge that?
Lithium batteries have their own chargers. They also have circumscribed shipping circuits. They do not make yourself a lot of. I have been the most important of the light of the lithium when the voltage battery is increased by exploding and your way this is not an electronic circuit that prevents the lithium battery from the stop for the shipping over the arrival of the voltage 4.2 v
Proper way to charge Li-ion cells is CC-CV (conctant current - constant voltage) method so you should use DC - DC converter with a current limitation or that one with li-ion cell charger (like for example tp4056). I think that you good idea is adding somewhere in video the inscription (You do everything at your own risk).
Can we use XM-H604 module for charging 18650 battery pack safely ?
@@chamunu123 Idk. I can't find this module. If it support cc-cv method and you can adjust current to cell ratings, then it should be safe. Moreover at high current it's good to monitor cell's temperaturę.
Is this module safe for overcharge protection
Only method 3 is fine!
What's the name of that board, for current or voltage adjuster
Hey MR. Electron, thank you for making this video. I want to 4 good cells of 18650 li ion, for my laptop battery. Can you help me buying ? I'd be really helpful if you can provide a link.
So like a power inverter.
look like you have the positive and negative backwards
bms is the best option for chargigng battry
Please don't follow the first two methods and in the third method, use a converter having current limit feature.

Bro how to charge 3s bms fully by 12v charger
Hy kid use a resistor to limit battery current and use diode in forward biase with battery this will properly charge your cell
Funny Video guys. Real title : How not to charge Your battery!
mc gyver experiences
Sorry so nicht was ist ein Wellen Generator,keine Berührung der batterie,las sie Fummeln
Its a manual charging ! You need to be near it all time it needs !
My I use 12v transformer power supply
Is it dangerous to health of li-lie battery?? DC to DC charging??
Really dangerous ideas. You want to save few dollars to charge without BMS and got risk to burn whole house when batteries wil be overcharged and overheated... You should... no, you MUST explain to subscribers how dangerous these ideas ;(
Safest way to recharge any battery is by using battery management system= BMS!
Atafok you are crazy
Thank you for this comment#**********#
Oh my God
Hallo real Mac Gyver 🕊
Use laptop charger 19 volt fast
How to charge 2.7v super cap
Just set output voltage a bit under 2.7 v, capacitors needn't constant current. But for safety I recommend to add low value resistor or bulb. Because curent in t=0 ( moment of conection) tends to infinity (teoteticaly but in real is limited by resistance of wires).
Ok sure 😀
@@filipaugustyniak3822 i mean how to use charger or where i can get 2.7 v charger
Can u share me the link of the 12 v battery uve used
Can I charge my bettrery from mobile charger 5v 2amp
No for 3.7 v battery make sure it's below 4.2v
Do not play with things that you have no idea, charge these li-ion batteries only with suitable chargers who are made for this
Did you research before you did this video?
easy ways? more like hard ways. Just get CC/CV converters and leave it charging. Or there's cheap lithium charger that works just fine. If got more budget, then get a fancy smart charger for "fast charging" and battery capacity reading.
this is wrong but sill can be done, it's like an unorthodox pre charge i even do his with alkaline .....18650 must be hot
Hello dear I am learner
Or buy new 32V-10A power supply
And what about bms..???
Do u know what bms is..??

Thanks for the first bit, but assembling a kit is not DIY. Please don't use misleading titles.
with out using BMS MODULE the 3.7v battery will die after a few minutes.
Batteries differ a lot. What you do is only good for emergency situations, if you charge a wrong battery type this way, you either shorten the battery life or may even make it explode. be careful.
4:28 You set it to 4.20, hell yeah (⌐□_□ )
Your video thumbnail is misleading
So your saying I gotta jump start my vape
the first method might make the battery explode
All wrong. Li-ion batteries are charged with constant current. These methods are constant voltage. Wrong. Constant voltage is the method for charging NiCad batteries. That is why they have different chargers depending on the battery chemistry. Temperature also needs to be monitored so they don't explode. Buy a charger. Good music though.
he did these things, really? i'm washing my eyes now.
Well first one will blows caps of lithium ion battery...second one is used for slow charging of car batteries by adding 12volt bulb in serries but is only for lead acid battery when connected to 12v battery charger ...the third on is also not appropriate as number of cells of 3.7 volts connected..sum up with the right ampage...as three cells each 2200 mah will be 6600mah or 6.6 amp..specific charger which can handle more than 6.6 amps is needed ...other than all three are inapporiate..☠☠☠☠
remove the light polb and no wast
Step 1 and Step are not charging method.... These are destruction means.

Just buy a battery charger, it is cheaper and safer than any of these methods.
Hmmm...you should build a nuclear bomb....

WARNING Go out and BUY a proper certified charger, you will SAVE your life. These 18650 batteries are EXPLOSIVE and can easily catch fire if not charged/discharged correctly.
Lies
@@borne777 of course crooks selling these cheap da ngerous batteries on Ebay will say "lies" as they get exposed. Just search "18650 batteriez exploding" on RUclips and see how good your lies sre
1.000&
are you serious or its a joke ?? ,, you miss a part
12.v to charge 3.7 is like the crazyest thing i have see after putting his head on a microwave oven
but , if you put , your 3 cells in series ,, a full 18650 is 4.2V , so 4.2X 3 = 12.6 , by this way , your 12V battry will push amp to your serie and when the voltage of your serie and the battrie will be equal , your battries will be full charge , without destroyin it ,,,, please redo your vid with this method insead of this lithium lead gel-acid bomb
You don't have much of a clue, right?
