Thank you for reviewing this module, and also great review!
Just a note, you can not apply your time to charge calculation, since the current will lower once cell reaches near 4.2volts, the real time might be something like 3 hours depending on the type of cell.

Hello Sir. Thank you so much for the very clear explaination. This is way better than TP4056 charging module. 😊

[basimrasheed]

Perfect streaming, love your explaining why and talking speed 🌹

Everything that I needed to know about the tp5100! Thank you!

Mr. Shamshiri, I truly enjoy your videos with the thought process, planning and the abundance of information you provide. After all, it takes work to video, edit and review your work and I find it flawless. Even corrections.
I have an entire line of cordless tools for sears back when I could work. I am prepared to disassemble and pass judgment on each cell. How or what math is used to determine the current to charge cells the show promise? A dead battery is dead, but unless it has a dead short internally, it has a chance to live again. I take the numbers stamped on the shrink wrap and research to find voltage but aH info. I can not order every single cell ti fix each battery pack as it would be cost prohibiting for my wallet. But having 9 perfectly good tools sitting on the shelf does me no good.

I have already used your excellent product testing videos to pick two modules to purchase. Thank you again!

Hello Sir. Thank you so much for the very clear explaination. This is way better than TP4056 charging module.

[ranakhandkar]

Thank you for this very detailed review, sir! Learned quite some new concepts from here.

[AshaSharma-lyzl]

Sir, you have taught me for years in the form of your videos
Thank You

[pablovasquez]

Your video is very instructive, thanks for the information.

Excellent explanation for a novice like me. Subscribed.

Hi... The circuit does not have any output for balancing the two-cell battery pack. How does the balancing work?

[Albaloshi]

Very clear
Thanks Sir

Hello bro Thank you so much for the very clear explaination

[pcastiglione]

Great video at the start of video you said different model for charging and balance what model where you talking about

[owlytv]

Hi I was hoping to find a small form factor pcb/charger for safe charging a 7.4v 4000mah battery I was hoping to use in a Raspberry Pi 2w zero project.

I saw your youtube video on charging circuits and thought you might have a good suggestion?

Thank you!

[Sumit-fvmp]

Thanks do we still need BMS along with 18650 cell to charge safely or this board comes along with all sort of battery protection ?

[acestudioscouk-Ace-GACE]

Thanks for making this informative video. If I just wanted more capacity, more amp/hrs, could I wire the batteries in parallel and use this charger please?

[macmusic]

Thank you Ahmad, nice video, great details

[ludovic]

12:10 Yeah !! thank you for pointing out the capacity unit which is Ampere x hour and not Ampere/hour.
It is good to put the unit in the calculation so we know what unit we got in the result.
It may be a details, but it piss me out frequently in other video or other internet source when they spread tainted information.
