You made it even better, than your previous battery project. Greetings ❤

Thanks for sharing your creativity ErCan. Your truly an inspiration for many of us. Keep'em comming 👌

so clean like always 😍

i loved it so much. it relaxed me

Dear Sir, Amazing work. I understand almost everything, except how you managed to get super fast charging with just 12volt and the 65watt pd module. It was my understanding that pd wasn't enough it had to be a pps charger.

Thanks! I ordered the parts. Question please: can the usbc charger balance 3s. On the description of the item it sais it can with minor change. You did not connect any wire after the short, right?

An excellent project, thanks for sharing.😃

Would it not have made much more sense to use a 7S3P arrangement in order to get the full 20V PDO from the 65W module? You get the same amount of capacity and so long as the other modules can handle a voltage over 12V it allows you to use the 20V PDO for the entirety of the packs capacity pretty much. Only downside would be the BMS becomes more complicated...I like these style of 3S and 4S BMS for the ability to put the BMS at then end of a rectangular pack and just solder or spot weld the overhanging strips to the PCB.

Pěkná práce, jako vždy 🙂

Those parallel strips you added were totally pointless except the one on the main positive and negative...but since the current is being drawn from just one end of the strip it wasn't quite as effective as a pack that draws current from the entire length of the main positive and negative series. The series connections carry all the current from one group to the next. The parallel strips are only for balancing the cells in each parallel group to each other...so current along that path, especially with matching cells should be extremely small. I doubt you'd ever see 1A for more than 1 second at any point in time along those strips although the cells furthest from the BMS connections will be passing energy down towards the BMS during discharge and during charge the cells closest to the BMS connections will charge slightly faster than the cells furthest away from the BMS so there will be a small current flowing to help the end cells catch up. The only other point I can make I believe I've mentioned on another video. Your spot welding technique is ignoring the slits in the nickel. Its there to make the current go through the terminal and properly come out where the other electrode is. It has to do with current following the path of least resistance. When you have nickel with no slit the current might find it is an easier path to just shoot across the nickel strip and never really go into the cell's terminal creating a weaker weld. Granted, this is more important for pure nickel which is significantly harder to weld especially in the 0.20mm thick and up region. I never use nickel plated steel unless I'm out of pure nickel but if you are using pure nickel and struggling to get a REAL weld that tears nickel from the strip and leaves a weld nugget on the terminal (popping off with no holes in the nickel, no material left on the terminal is a BAD weld) try rotating the pack 90 degrees from how you did this one and put an electrode on either side of the slit. I'd say it increases the thickness of material you can weld by 0.05mm of pure nickel.

As u have made it, I would like to ask you that, if we want to make it for 6v 3W

!!! Is it possible to use this assembly not in a UPS, but with an inverter, if necessary?

Nice video 👍

Cool video

Nice work 👍🏼. A question: in the event The PD 65W charger module is connected to a laptop for example which then draws 65W. Wouldn't the wireless charging module get burnt/blown up because of the higher current and voltage draw by the PD module?

Awesome video as always. Can u name that charging module that u use to charge the battery? Does itvalso work for LifePO4 battery?

Where can I get the batteries ?

Camera LED lights battery body kaha milega

Professional work Brother! Do you consideeing mass production and selling those? ✌️

Bro, Excellent 👍 Will be good if you add subtitle for the modules name, cell 18650 etc.. here just learning now New subscriber ...

Good morning. What is the liquid you are spraying? and what is it for?

👏👏👍🏻

👍👍👍👍👍👍

ভাই আমার এক পিচ। বেটারি টেষ্ট মিটার লাগবে। দেওয়া যাবে

What is the name of that green tape you use

10:35 what you spray here

i need this price plx

Parts links which are you using

👍👋👋

nice ..but the battery charging indicator is not visible

Amar one pice battery nit if you provid me

no knowings, result: such a silly thing

Nice idea but HORRIBLE DESIGN. Better hope no one with the latest iPhone or Galaxy phone sets one on top of this and shorts ot the battery terminals with the metal edge of the phone. Best case you are just going to short the battery and get a scorch mark on your phone. Worst case you either spot weld your phone to the battery, or short out your phone on this peice of junk.
