Glad it was helpful!

Its a simple dual winding transformer with primary and secondary windings. The primary windings takes 220vAC input and the secondary winding outputs between 4 - 12 volts, depending on number of turns for your spot welder.

Sure, i will consider it in my next video soon. Glad it helped

Sorry, i'll keep that in mind for future videos

Um, honestly i haven't calculated its efficiency but it would be atleast 85-90%. For stepping down DC voltage of solar panels? I'll not recommend this circuit as it is for low power applications only. Usually the solarpanels deliver high amperes at the load side so its better to use high power DC-DC step down converters as they have quite good efficiency. Increasing the number of FETs will not solve the problem as it also require current balancing.

@@ERLEngineering thank you so much means a lot really But plzzz one more question in market 400watt buck converters are available with 2 moesfet can i increase the no of fet in paralel on the same circut can solve my problem

@@Petsimnonsense1723 😂😂 true

Yeah that should work too but be careful a little scratch on the cells with that thing and you know the rest 😂

Ive done it xD

😂😂😂

Good one right?

Whr to use it

@@ERLEngineeringthat’s cool and all but be fr

Hi! you can easily find it on aliexpress

Thanks for your great feedback 🙂

If the laptop is dead then these cells can be useful, but if the battery is dead then still one can find single or more useful cells from that dead battery as not all the cells go useless in most batteries

He litterally says it man for electronic projects probably wouldnt understand

Yes, that will work just fine

But it is not. I have tried to connect the left right and ground ​wires in the connection where the buttons cable is connected but it isn't working @@ERLEngineering

Yes that can be an option too. This circuit is just showing a crude method to quickly increase the output current nothing else.

Thank you

Yes, the battery must be fully charged

Yes, most probably

Thank you

Please ask

You are welcome

Stability of voltage

Hi, you can get the code from the ERL Engineering instructables, simply type erlengineering instructables with title of this project and will see the main code as well as the calibration code there.

@@ERLEngineering thanks bro

A bms cannot be defined as best or worst, its about the specifications of the battery and bms, for either lipo or li-ion battery, you should check for overcharge protection, under voltage protection short circuit protection etc,. Also, bms circuits can be for single or multiple cells/lipo packs, so always check what is your requirement. Finally, the maximum current margin should always be considered depending on your load.

Thank you for your feedback, sure i'll try to make a video on that soon

Please elaborate the task so that i may prepare the video accordingly

Plz see aliexpress for latest price

Yes ofcourse, where do you live?

No, you have to make a wire with desired clips. Company do not provide it

With this module, i think you can charge a battery with maximum of 5-7 amperes

Thank you dear. Nice to hear it. 😊

Please see the ending of this video for the schematic diagram

Its completely different. Theres no buck converter in it. You also use different motor driver

Please see my community post where i have uploaded the complete diagram. There are 2 boost converters, and there are a variety of motor drivers which can be used for the same purpose in this project.

Great 😃

Yes, any arduino board should work

😂😂

Yes you can, If you are joining them in parallel then due to high resistance, you will observe a low current drop and longer time for each battery to discharge.

@@ERLEngineering One more question. besides discharging speed, Is there any different in capacity results between the resistor you have right now (25W 3,3RJ) and the current one (2 resistors 5W 7, 5RJ)?

No, this only changes the discharge speed.

@@ERLEngineering Thanks a lot for the information.

Welcome 🤗

Its in the description

Its not a diode, its a 25 watts resistor. You can find it easily on aliexpress from where i bought it

@@ERLEngineering yes its resistor and thank you for helping me

Welcome

I agree, if the power conversion is performed at the switching stage then it would be called a buck or boost converter. 👍 Thanks

😂

😊😊😊

Whats the meaning of this?
