We are living in a golden era. Or else how come we get such a quality content for free.

[@PredictableDesigns]

Thank you so much for saying that.

[@aviandragon1390]

Excellent teaching method. I appreciate that you assume the viewer may not already know everything while simultaneously not assuming they are too stupid to understand.

[@PredictableDesigns]

That's what I like hearing! Thank you!! I do enjoy teaching complex topics to those new to it.

[@mahmoudwatt5560]

Thank you so much John. I have been struggling to find a valuable content. Awesome !

[@PredictableDesigns]

Thank you Mahmoud, glad you found it valuable!

[@rahalhettiarachchi8967]

Thank you for the comprehensive demonstration! You deserve much more followers👍

[@PredictableDesigns]

Thank Rahal!

[@gaborungvari784]

thanks for the detailed explanation, it is really useful video with many practical details. keep creating similar ones please! thanks!

[@PredictableDesigns]

Thanks, will do!

[@maxim25o2]

This is best video what I see on KZbin. Please make more videos this type, because on internet theres are missing them. Please do baterry discharger, and boost and buck converters, because for baterries, if I want use arduino micro controller, have constant voltage but also power efitient is crutial .

[@PredictableDesigns]

That's so great to hear! I'm actually planning to do one in the next week or so on a buck converter. Thanks for commenting.

[@rick_er2481]

Great content, you deserve more views. Really valuable

[@PredictableDesigns]

Thank you!!

Diptrace, nice.

Hi , in my project i need to charge my device that consumes 60maH . i have few questions : 1) Will the battery charger BQ24092 supply 1 A till it gets exhausted ? Secondly , could i recharge the THE BATTERY once it get over using the circuit above ? . My device works as a watch , so just asking . I am new to electrical field so pardon for my silly doubts .

[@theGamer-kt9pf]

2:12 can i charge 2 Samsung ICR18650 2500mAh cells connected in parallel with this battery charger

[@ronnymees8074]

Hey, do you have an answer to your question already? I also would like to charge 2 18650 batteries in parallel.

[@kingyachan]

The data sheet says 1s so think that means no

[@chethank8716]

thanks for the content, and i think this chip set lack in protection, can you suggest which type type of ic's are required for single cell battery charging

[@Amiraldz]

Thaught it's about offboad EV charger, anything like that out there ?

[@theGamer-kt9pf]

Hello sir Is there any alternative of BQ24092 IC which has charge current upto 2 amps from TI

[@chouchenewissem2328]

Thank You John, do you use ISIS for the design and pcb , what tools do you recommend for design, simulation and PCB ?

[@PredictableDesigns]

I used DipTrace for this design and that is my preferred design software for most designs. It doesn't have all the features of software like Altium but it's more than sufficient for most designs. Super intuitive to learn and orders of magnitude cheaper than Altium. Thanks for the comment.

[@calvinaizumiramadhan2685]

nice video. thanks a lot. sir, do you have the scematic esp32 to read 4-20 mA and 0-10 V dc Sensor in one board ? if you have, can you give me the scematic, thanks you..

[@tecbeast9323]

I want to learn and already subscribed your channel🙂and thanks for your video

[@PredictableDesigns]

Fantastic to hear!

[@mattemito10000]

Hi, if you have to design a circuit to charge a 3 cells battery which ic would you use? I've found the MAX1873SEEE that has a decent package (and I would add a balance circuit)

[@mattemito10000]

I think three S-8209B could do the job even better (but it doesn't have any shunt resistor...)

[@kabandajamir9844]

So nice thanks sir

[@PredictableDesigns]

You are most welcome. Thanks!

[@chethiyawijewickrama6425]

Hi what is the design tool you are using here?

[@PredictableDesigns]

DipTrace

[@h4l050]

Hi, i'm sorry for the noob question: does this charger IC has any sort of overcharge, overdischarge and short-circuit protection? Thanks! Amazing content!

[@PredictableDesigns]

No, not really. It has short-circuit protection for the charger, but not the battery. The battery protection is generally embedded in the battery pack itself. Most LiPo battery you can see the protection circuit PCB at the top under the tape.

[@JG-mz7hg]

Check the STNS01PUR :) This IC + MAX17048 fuel gauge is all I use for most of my designs.

[@johnaweiss]

Would be cool to know how the charger does it's current regulation magic.

[@user-vz2qp2kn4r]

hi dude nice work do can you put a link where i can download schematics and the pcb layout

[@user-vz2qp2kn4r]

bro i need the schematic and the pcb can you give a link for that?
