How to Make 2S 3S 4S Battery from 18650 batteries 

The video is good but female power connectors should be used on battery side to avoid any chance of short circuit and also one thing is lacking that connections to the BMS should be in video for better understanding.

Thank u sir, I've been Fighting with this 4s batteries for 2 days, and ur vid and 4s diagram have saved my sanity. U rock

You have found a lot of brains - I used to go to the same recipe for six months but no one had that much knowledge Muginambo was happy -

now this is a channel what deserves subscription! No bs hello youtube bla bla bla, just pure explanations, and DIY. got my sub man! Thanks for the vids!

The best tutorial ever in making diy batteries. Thanks you

I make the 3s battery pack in according with you video. Thank you my friend.😃 👏👏👏👏👏👏👏

Nice work on this video! Succinct, pleasant audio, and very informative! You’ve earned yaself a sub!!

hello I would like to make a 12 v battery with 3 x 4.10 v batteries. - do they have to be mounted in series? - Which BMS do you recommend? thank you for your videos.

Great video, like it!👍 Thank you!

Never put the male end of the connector to the battery. Always female end. Otherwise there is risk of short circuit and fire. VERY BASIC

Thank you for sharing bro... Keep it up

What is the size of the heat shrinking tube you used there for the 3S pack please ?

What sockets do the T connectors plug in to? Do BMS boards come with the receiving connector to one shown?

Can a poor spotweld cause a drone to brown out in flight? I got my nickel strips to stick to the battery cells, but I didn't see any sparks. I powered my spot welder circuit board from a jump box that's used for jump starting cars. The Molicel 18650 2800mah 35a discharge batteries should be plenty to power my 7 inch drone for a cruise flight.

I would like to make a 3S1P using 3 18650 batteries. The batteries are protected, do I need a PCB in this case?

hy i've got some sony murata 3100 mah 35A curent cells to make a 6s2p pack , my concern i about how many nichel strips do i need to get 35A per series pack (35 per pack will lead to 70A discharge total 2p config), i have some 0.2x8 mm pure nichel strip that i've heard and tried that it doesn't like to stack multiple layers, and some nichel plated steel that weld better more buttery. Are 4 layers enough ? should i alter the strips to have steel nichel steel nichel ... also i think it is better to connect the cells in parallel using the strips, at each joint of 2 parallel cells instead of just at the end like if they were 2 separate packs, it should help with balance, but i ask just to be sure. Also even if i stack enough strips on top of each other, all of them will interact with the cell using the tiny spot welds of the first strip that conects all of them to the battery trough it, are they gonna be enough, those spot welds ?

any alternatives for nickel strip and insulater ring. because I have all the things except both of them please help?

Thank you, dear people 🙏💕

Which jumper is better to use for assembling Molicell 21700 42A - 6S What thickness and width of the steel tape is suitable for peak loads of long-range quadcopters. I want to use metal tape and welding instead of soldering

Nice! Thank you, after one day of headache i can finaly finish it 🤣

Good Job!

Do you have link where you buy your spot weld ? Thanks sir

what's the difference between Enhance and Balance version for bms ? thank you

Nice video. Keep working. What is the heatgun you using?

literally exactly what i needed

Hi Lahis , great video , but now they have more advance BMS board in the market , is the 4cell suitable to use with the 40A board , due i need to change my Ni Cd battery to Li on for my drill, your advice please .. tks

So the same batteries I use for my vape and my laptop also power my RC car... badass 18650's run the world.

female connector should be used to avoid short circuit between positive and negative

El conector de la bateria es el otro ANIMAL!!!!

très bien c'est excellent

question, when I charge the power bank, can I charger it using a regular USB wall charger? output 5v 1 amp or 5v 2.1 amp? please let me know.

very very thanks for this video

Hi! Guys a question! what would be the proper way to charge these?

Do you know where buy 18650 Batteries for drone racers?

You make the main port exposed it can short anytime

The best quality of batteries that this is bought

Nice vid. Helpful!

Very good !

Can 3s may be usefully be used in drones?

i can chargued with 13.5 V at the bms 3s? how many voltege used?

Can you use a 6S cable for a 3-battery pacl or a 4-battery pack please?

Thanks!

Where to purchase the orange battery holder?

Good I need your advise Can you recommend this spot welder In local electronics market Sunkko 709A with 18k no warranty available I just need to start battery making small business in home What is your suggestion Thanks

Great vid

That is amazing! Gee wee!

THANK....THANK.......!!!

We can save a lot from these! the only cost a lot on this project aside from the batteries is the arc welder.

Excellent.

Did you also made simple spot welders with that male T plugs?.. Lol.

Nice video!

Thank you for sharing, good for your labor. Which (Volt and Ampere) adapter can we charge the serial group 18650 batteries with 4S and 5S BMS? For 4S to 16.8V - 5S to 21.0V, the min. and max. If I can learn how many Volt and Ampere values it should be, I can choose from the adapters I have.

For what purpose this batteries will be used ? Please present a video of this use !

Hi Why you connected the connector? What's the reason?

Creative video, thanks :)

are you able to charge these?

Which charger used for 2S

The t-connector is the wrong one, May cause a short circuit because the poles are exposed. Regards

Whats the switch for?

GOOD ONE

Nice install bro new frnd her

What about discharge protection?

I need a spot welder in my life right now

Thank you this is exactly what I needed to see.

haii how to use 3s with 3 pin cable for remote control car??

بعض الاحيان نحتاج زوم. لمعرفة الربط او الفهم شكرا يا مبدع

10.03.21 Thanks!!

The red part he puts in the end is to charge the battery right?

Very nice 〰〰〰👍

Super 👌 👌 pokazane pozdrawiam

Exelente q berraquera

What is the use of balance cable connection

Dear Sir You don't perhaps have the file to print the battery holder to solder the batteries please

Nice 👌👌

I been looking for a lipo cell holder like THAT! Where can we find/buy them? Thank YOU!

How do you balance charge this

Why does it bring connection break in imax b6???????

excellent

Con todo respeto,me parece muy bien el enseñar,pero creo que falta algo de información.Falta una parte importante del montaje,que es ,como se cargan las baterias.Un saludo.

hola que tal ... para poder alimentar un autoestéreo de 12 v pero no se de cuantos amperes, trae un fusible de 10 amp como protección, podrías instruirme con un diagrama y todo lo demás como una bms y para que cargue etc. de antemano gracias

3s how many amps does it have ???

needed to c this

Sạc đó anh mua ở đâu vậy ạ

What GAGE WIRE ARE YOU USING 20?

appreciate the video but you NEVER use the male end of a connector on a source, EVER

Bro. thi is a better way to make 2s. 3s for 7.4v. & 11.1v battery with more ampere. but how can we recharge it ? could be it recharge with B3 compact li-po battery charger.........? please clear my doubt kindly......

Good job🇮🇳👍👍 Kuki

Nice

What's their volts, 2s, 3s and 4s?

I am using this 3s battery for running 1400kv bldc motor but one of the end battery is getting discharged soon and also when I start the motor and increasing its speed to maximum then in few 2-3 its speed is getting low to half of its max value

Y si la de 2 sueldas lo necesito para un taladro de 7.2 volts ? ( porque veo que lleva un BMS

Mere bms board se output nhi mil rha h kya kru.. Sab connections sahi h but no output plz tell me solution

Can Icharge this to a Lipo battery charger?

建議 電池輸出端子使用母接頭，主要原因是電池輸出端有常態性直流電輸出，因此使用母接頭可避免與金屬碰觸而產生短路(火花)。

What's the name of that tape in blue?

Bro make a door lock hole mortise kit

bravo

Good morning Bhai

İ used same method for 2s 14500 li ion but both 7.4 lipo and lion charger dıd not charge it. Finally l removed 2 s balance plug and İ charged it one by one with 3.7 v li ion charger. Where is the problem?

sir ya dron ma us ho ge ya nahi
