*This battery reconditioning program exceeded my presumptions. It worked on any drill battery, several AA and AAA batteries, **batery.repair** and any camera battery. The steps are simple and the act itself is exciting to do. No matter what type of battery you`ve got, it is sure to function again!*

This was very helpful to watch, thank you for making this video. I will be making a few 4S batteries myself using this tutorial. Thanks!

Thank you very much, nice video. I had trouble wiring my batteries and you explained it very well. (had the neg wrong). Thanks again!!

GREAT VIDEO! YESTERDAY I FINISHED A 3S LI ION BATTERY PACK. BUT I WASN T SURE I DID WELL. AFTER A NIGHT OF CHARGING WITH A LIPO CHARGER, ALL THE LEDS WERE GREEN THIS MORNING. YOUR VIDEO CONFIRM THAT I DID EVERYTHING IN THE RIGHT WAY. NEXT STEP A 4S, 5S AND 6S LI ION BATTERY PACK. THANKS FOR THE VIDEO!

Really fantastic your demonstration ... very cool !! Thank you so much!

Thank you very much for your valuable teachings, my friend. I send you many greetings from South America ... Lima - Peru.

Best welding machine I've seen in 30 years of industrial engineering :D

This is like a new world to me, Thank you!!!!!!!!!!!!!!!!!!!!!!! ❤

Great tutorial. Thank you.

Excellent job, very well presented, cheers....

awesome, just finished a 3s pack now, minus the spot welder. as long as your quick, a normal soldering iron works perfect.

Nice guide there :) Good that you also added in balance charging connectors. Only things I would say is that: a) a soldering iron can be used if you don't have a spot welder (like me) b) for best lifespan, you need to capacity check each cell (on a balance charger like the one in the video) to see what its capacity is like - as laptop batteries will vary significantly, and the pack will be limited by the cell with the worst capacity.

thanks you are great i build more two batteries for my wingsland M5 drone

Very nice and helpful video ! Thank you very much.🙏🏽

Thanks for the video ;)

Do not forget to balance your 18650 batteries before putting them in a pack, this way the voltage is almost the same and will be charged faster. Great video, i have been doing it like this for many years now😀🇳🇱

All respect for your beautiful business

Hi . I love your videos . Thank You for your time and effort to make them !!!

I like your project.👌

Oh my god!!! great.

Thanks! I actually needed one of these vids to make a rechargeable battery for a old phone (samsung alpha, the battery would not charge but would heat up(not to hot just warm))

thanks creative channel it is best channel

Great instructions

Veer g i love you...you have saved my money....Love you

Perfect tutorial ⚛️

The activities I have seen here is quite educative I can confess

saludos y gracias por gran aporte, y aqui me tienes ahora desvaratando todas las pilas de laptop que encuentro :)

Holy 18650s! Great idea but damn be careful. These babies are not happy when shorted.

muito bom!!!!!

Great tutorial on wiring batteries for balance chargers, but would love to see one of your spot welder, that interests me the most.

Super, thanks.

excellent video thanks!!!!!!! :D

Super good.. Edukasi.. Sir.

well done creative channel. I love ur uploaded video. ur videos r excellent

eres de mucha ayuda. muchas gracias . no lo tenia claro pero ahora si.

The adhesive tape that they use as it is called, I really liked to use it in several projects. Thanks in advance.

Thanks for the video. Even though there was no verbal explanation, every thing was understood

Great video! Would be nice to get a list of all consumables, used in this video.

This guy is a genius, but that's doesn't mean all viewers are too. We can't tell which wires go where when soldering small set

شكرا جزيلا فيديو رائع ومفيد Thanks too mutch

Thanks for the great video, can you please explain how to wire for balance charging through balance charger if 4 cells were to be used as a 7.4v pack in order to increase capacity, similarly as it is in the actual laptop battery pack, ie. 3 pairs of cells for 10.8 / 11.1v? Or would the two parallel cells just be counted as one (with double capacity) by the balance charger?

As others are mentioning, Use a BMS to stop over discharge which WILL kill your batteries. Also, do capacity tests on the cells, match cells as closely as possible by capacity and ALWAYS run a MONITORED charge/discharge cycle on each cell looking for temperature, throw out the heaters.

très bien c'est excellent

Very nice work!

é bom quando vc fazer um aviao ou um quadrocoptero, amei esse video!

Very Nice and Helpful Video. Allthough i have some recommendations. 1) Dont use a Lipo Charger for Lion Batterys. 2) Use thicker wire for the main Leads because the bigger Packs can output higher current and if you pump higher current through those thin cables, they could cause a fire, so please be careful. Have a nice day! ;)

Nice video well done. But those are not Lipo batteries but Li-Ion. So the charger should be set to Li-Ion as otherwise you will be overcharging them to 4.2V per cell instead of 4.1V. Not that they will explode but still not their correct and normal full charge voltage. Keep up the good work!

good video thanks

Have you a video how you build your welding equipment with this power supply to make point welding on aluminium?

Nice ..... Creative work...

very good tutorial

Great video. How would you connect the balance leads on a 3S 5P

Please show us how to build your home-made spot welding machine. The ones on eBay cost from US 120 to US 250... Too expensive... The one you made seems to work OK. It is doing the job.

love you thankyou

thank u !

Always enjoy yr vid. Looks like there is no low voltage protection in these batt.. how to prevent lithium Ion voltage fall below 3.7v batt cell?

This old charger only safely charge the batteries but no protection for over discharge,which kills the cell . Use BMS boards for perfect in and out power.

Cool Mann thanks a lot

Very Nice

great video thanks! - would love to build that mini-welder! Do you have a video regarding this?

good idea!!!

I think these batteries will not work as effective in some projects as Li-po do. Li-po 2s, 3s, 4s can provide higher current as compared to Li-on used in laptops.

Neat idea but I don't think they will perform anything like a LiPo. They don't have the discharge rate for high current draw.

Great video man, It is posible to charge them with a solar panel? Link of the charger balance? Thanks for your kelp.

hi. I'm thinking on doing some battery packs myself. Do I need those protection boards (BMS) if I use similar charger like you have? (imax b6) (where I will use them, i will have some electronics to check each cell voltage - altough I won't have the ability to detect short circuit - overcurrent protection?) Thanks!

Your are the best

perfect

Thank you

Would you please tell me the name of the tape and the balancing pin and the steel you used in this video

For 18650 bateries like those ones you dont need that much proteccion, you can charge one with 4.2 v, 8 v with 2s and so on

i like the idea, and the tool that you use to solder the tape with the battery how did you made it ? min 3:12 it seems like you used an ATX power supply to use it?

hello friend your videos are excellent could you do me a favor to give me the configuration for the wiring balancer I would appreciate it. a question this pack of batteries can be used in drones I would appreciate your help and advice I want to make a pack to control my syma X8C thousand thanks success in your other projects

What did you use to increase and reduce speed of motor it was connected to that 3 wires from the esc

Hello, how did you build the soldering machine in points?

tq bro working

Wow está increible

Nice👍

Muchas gracias no dices nada pero lo entendí perfectamente saludos

Grait video

super bro

mate all I need to know is how to make a easy welder for the tabs, may be based on capacitors , MOSFET .... a small unit cos it's not something we need everyone's day. my soldering is not that bad, so far all my battery packs have been working well. I'm always scared while using solder iron on 18650's

i love diagram :D

Nice work but those wires look like they're going to melt under high current (basically anything RC)

Explain neatly

nice video.

which camera do you use?

hoooooooooooooo very good...

Wow amzing....

4S Battery Diagram is great.

Nice

Super bro nice

Very Very Very Very Very nice

great 😃

👍👍👍👍👍👍👍 terimakasih 😘

thanks

Please provide the link where to buy those long balance charging cables and tapes. Thank you.

nice vedeo

GjB Bro

Nice and cool bro

Great!
