Awesome, looks like you've stepped up your video production a lot!?! Looks great! The battery pack looks very neat and well built, good job Steve! Steve

Stephen Ludgate This means a lot , Thank you soo much

It took soo long to find a video that was 80% detailed... Thanks Wilson!

@jwrhynejr.6689 6 лет назад

Thanks for the video on your build! Great job! Liked the spot welder and it's use view!

@davidedgerly Год назад

Thank You Steve for sharing this info with the world... I built two packs so far using your instructions... Both are flawless..Cheers!

@SteveWillsonKujur 6 лет назад

Ravs Ajay Thanks

@catkiller395 6 лет назад

Hey Steve, great video! I was wondering if the BMS board you picked up does active balancing or only when the cells exceed 4.2V? Because similar boards have charging protection set to 4.28V before it cuts out - which is quite high. Thanks!

@pjaro77 4 года назад

Nice spot welder. I made my own very simple from 500F supercapacitor.

@pjaro77 4 года назад

I had problem to add the solder on the pads and also the nickel plated sheets. What temperature did you use and what kind of solder ?

@exotime 2 года назад

Great and clear. Thank you.

@IntegraGSR5 5 лет назад

I used the same bms and connected it the same way with this built but it won’t charge. Every time I plugged in the charger the input and output read the voltage of the battery pack instead. Any helps would be nice

@bleedaholescousin Год назад

I want to do this with 21700 cells. do I just add a step down to get 12 volts so I can use on my 12v equipment

@jasonyannuccelli2499 5 лет назад

Nice video Steve. Hey someone else has asked this I noticed, would you mind helping me with the diagram of the battery arrangement. I have tried to take lots of screen shots of your video but still can’t see well enough to be sure of getting the arrangement right. Also the diagram of points from the BMS to the pack. Many thanks 🙏

@marcelovivero9685 3 года назад

Hi! in your video presentation can i use 12V Solar Panel as an Input Charge Voltage in order to charge the batteries?

@jaysonhernandez6728 4 года назад

For each battery pack for example that 4s2p running at 8A will. What will the amp current ot each cells in series and each cells in parallels? Thanks

@startcherif 6 лет назад

Pls STEVE, have big picture for the BMS. Thanks

@bolittle_fn9068 2 года назад

I’m kinda dumb and I just built a 4 cell battery with a output of 16v and 4 amps when fully charged. Then I attacked my BMS once I did that it can’t seam to charge or run anything. The specifications for it was working current 30 amps. Does that mean that I need 30 amps to run it?

@filoteogonzales464 6 лет назад

i made a 1P4S Li-ion battery pack using exactly the same BMS on this video for my handheld vacuum but works only for about 2 seconds everytime i turn it on. what's surprising is it will run continuously if i use a smaller wire size (~AWG22) from P+ of the BMS to the switch terminal but the wire gets hot though. is my BMS faulty? i measured the resistance of the smaller wire and the original wire and got 0.8 and 0.4 ohm respectively. is it a significant difference? please help and thank you in advance.

I have the same problem of u and same prob with my second board see my video ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-wRLocc-y724.html

Why the white connector on the pcb leave blank? What is it for actually?

@tooshmart6669 2 года назад

If you balance charge 2s2p (4 cells), 3s2p(6 cells), or 4s2p(8 cells), will the balance charger charge every cell or will count each parallel pair as a single cell when using 18650"s ?

@reinveenstra1 6 лет назад

What soldering iron do you use?

@MotoBoyarin 5 лет назад

I am confused, LG B4 seems low power cell (as per google), but you use 14 awg wires - meaning high power. Where is the catch here?

@sebastianmarvin6372 5 лет назад

why you don't use 6 pin balance cable which included with the bms?

@SteveWillsonKujur 5 лет назад

I directly solder it on the board

@arrancushnahan799 6 лет назад

Nice could you do the same thing but using a 6s bms

@jayakrishnans2785 3 года назад

Quality video,✨🔥

@urtiaga71 4 года назад

Hi, great video. But... Why you don't use the wires connector (the white one) of the BMS ?

@pjaro77 4 года назад

I think because the wires are very thin and he wanted to charge with higher current.

@baigmirza4257 5 лет назад

Hello sir I have 3.7v 12cells means 48v so which type using balancing kit please give me reply

@jeremyhenderson163 5 лет назад

What is your power need,what are you wanting to power (voltage,amperage,etc). If your power need is 48v then you need to know the amperage (or wattage needed),if your voltage need is smaller (say 12v) you can build a 4s3p (or 3s4p,but will only supply 12v when fully charged. Meaning you will need to keep the battery fully charged in order to use it.) and step the 14.8v down to 12v with a step down module. If I knew your power needs (voltage,amperage,wattage.) I might could help a little more.

Yes

@aryajayasuper 5 лет назад

@@SteveWillsonKujur : i want this battery pack with BMS connect to some speaker amplifier. i test the battery, how long is run for this amplifier with some MP5 kit. If the BMS detect overcharge, it will turn off amplifier directly??? sorry for my bad english.

this bms is fail on load. drop some voltage and curent. so chep make it's easy damage BMS.

There's a website robu.in Search for orange 18650 cells I have bought one and works fine And also the capacity is also wuite accurate

@AtarRoux 5 лет назад

Bajaj Sahab just keep making it bigger. If you need a video on how to make one maybe this project isn’t the right way for you. There are lots of kits that will allow you to do the same without the hassle of soldering and making hard connections.

@neutronpcxt372 5 лет назад

Yep. Just put 13 cells in series, and 50 in parallel if you can. However, you would need over 100+cells to do this.

@gemudesugaming9157 5 лет назад

@SteveWillsonKujur 5 лет назад

@luisrovai 5 лет назад

your bms wiring seems incorrect. B3+ should be in the third pair of cells.

@iconjohn82 2 года назад

The video main purpose is to show how to build 4s2p battery... but it only shows what you are doing...lack of explanation and information, which wire goes to and no info about spot welding a tabbing strip to a battery, you should tells us more how the series or parallel has been executed on a battery.
