Thank you, your video answered a number of questions I had regarding charging lithium batteries.
I'm glad the video helped
Thanks for the informative video. I bought a gadget to charge the battery and was slightly alarmed when it indicated fully charged 3.7v cell to 4.2volts .
I thought i knew almost everything about the topic until I watched your video ❤
I'm glad that you learned something from watching! :)
The main problem with using a rechargeable battery is a circuit that can supply power even while charging (charge power separate from output power). TP4056 kind of works for it, but what we really need is a PMIC
In case for a 5V controller supply: Is there a one module that does the charging and DC2DC to 5V? the modules with PCB are quite big.
The hot plate that you used greatly improved the look of the circuit board, although it is fun to use a soldering iron.
It makes SMD soldering much, much easier.
I would like to ask if I can also use this charging module in charging my li-poly rc battery. I'm planning to charge my battery through solar, though I'm quite unsure if using this charging module will be suitable to li-poly batteries
which mosfet you have used ?
Hey there, thanks for the video! I'm kind of new to making electrical projects such as these, and I was wondering if the battery you use would be able to power a microcontroler such as an ESP32. I noticed the voltage works fine and could work even better if connected to a voltage regulator, but was wondering about the current. Does it supply enough amps for the ESP to work?
LiPo batteries can supply a lot of current. It is more than enough to power an ESP32.
Sir, I am looking for a battery backup for my AVR microcontroller.
I am using 5V 3A SMPS to run my microcontroller board.
What I want is:
When MAIN Power Supply goes OFF suddenly- due to power cut, then microcontroller switch to battery.
Is there any Module available in market , Which Switch between "5V Battery" or "5V SMPS" depending of situation.
Also battery should charge automatically.
Please guide or make a video on this topic ......
Is it now possible to use the LIPO battery while charging?
I was literally looking into the same chips today. I have an application where I usually have my device plugged into USB C 5v for power, but I would like to be able to unplug the power and still use it with a battery. I found some boards that do exactly this and have a 5V boost converter to bring the 3.7V up to 5V.
Unless I'm misinterpreting what I ordered on Amazon this chip solves all the problems.
Yes, they should work, considering that they have the necessary protection features.
At 6:30 you connect Battery to TP4056 and then to LM2596 right?
I'm connecting two 18650 batteries to LM2596 to supply 5v 3a to my GSM module.
It's working fine but I want the circuit to shutdown once the batteries are low on power.
You can find battery protection ics. They will disconnect the battery from the circuit when it has been over discharged.
Can the TP4056 provide enough power for a ESP32 WROOM-32 board? Can I use 2 18650's in a holder with the TP4056?
18650 with TP4056 does output enough power for ESP32, with the help of a buck converter from 3.7V to 3.3V you can connect it to ESP32's 3.3V Vin pin. If you use 2 x 18650, make sure the holder is wired in parallel (same voltage while increase mAh capacity), fire hazard if wired in series due to TP4056 can only charge 1 cell and does no balancing. When connecting 18650s it is required to charge both 18650 (individually) to max or at least to same voltage before connecting parallel, otherwise you risk damaging 18650s
could you please continue the am transmitter and receiver? and maybe move to fm transmission (because there are not many intermediate videos, only beginner with no explaination or hardcore theory)
I'm still working on those, I did a battery video in the meantime :).
Are you sure that Li-Ion and LI-Po are the same? Maybe they aren't exactly the same! en.wikipedia.org/wiki/Lithium-ion_battery en.wikipedia.org/wiki/Lithium_polymer_battery and for good measure en.wikipedia.org/wiki/Lithium_iron_phosphate
"essentially the same thing" is correct and they are "essentially" but the 'Lifepo4' can catch people out.
@@andymouse it is essential to understand that different batteries have different usable voltage ranges. This is critical for power delivery circuit. For instance, LiPo batteries can withstand voltages of about 3V without any damage, while LiIon batteries can go as low as 2.5V. Therefore, it is crucial to consider the specific voltage range of the battery you are using when designing a circuit. Remember, there is no "essentially the same" when it comes to designing circuits.
was pointing out the fact that a lipo and a lion can be used with the same chargers and they can, plus the fact that Life are a different kettle of fish and nobody mentioned the over discharge threshold at all besides it was 2 moths ago. and I don't need a lesson in design from a total stranger on youtube ! good day to you Sir.@@AlenHR
Why did you voice over your intro 🤪 I’m sure it was just fine. Don’t care so much. Just do you. You are incredibly smart and a wealth of knowledge. You are appreciated. Don’t care so much about perfect presentation. You will find that people may also appreciate you not cutting things out or including mistakes that were made because it makes you feel more human and more relatable.
EDIT: my computer was lagging and had the video misaligned with the audio. My apologies. However I still think the advice I provided is solid :p thank you for everything you do.
Thank you. It's good to hear that you appreciate the videos :)
let people do what they want lmao
