Power Your Projects With Batteries! (LiPo/Li-ion)

[@GiNodrog]

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 .

[@cpk001]

Thank you, your video answered a number of questions I had regarding charging lithium batteries.

[@SineLab]

I'm glad the video helped

[@xzddakfdmiug5832]

The hot plate that you used greatly improved the look of the circuit board, although it is fun to use a soldering iron.

[@SineLab]

It makes SMD soldering much, much easier.

[@narayanbandodker5482]

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

[@jumbo999614]

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.

[@SineLab]

You can find battery protection ics. They will disconnect the battery from the circuit when it has been over discharged.

[@alcendinoneto]

Thank you so much for the video! Amazingly clear and instructive.

[@sanjaybatra6593]

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 ......

[@anshulsingh8326]

The first black part (near micro usb) gets very hot in few seconds. Is this normal?

[@megabc333]

Yes, especially if the battery you're charging has a very low charge to begin with. It can get up to 80 C or more but will cool down as the battery charges

[@anshulsingh8326]

@megabc333 Ok thanks

[@henriquealves4068]

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?

[@SineLab]

LiPo batteries can supply a lot of current. It is more than enough to power an ESP32.

[@riverainventions]

Thank you

[@MrI8igmac]

Good job. I will have to watch this again. Im building a drone, and i need more knowledge of battery safety circuits. I have cracked open cellphone battery charging bricks. Its not as simple as swapping the big battery for a smaller battery.

[@natureenthusiast660]

Bro, dw01 chip activates over discharge protection at 2.4v which overtimes permanently damage the battery capacity, if the load is low dw01 can destroy a liion battery in ony cycle. 2.4v is even more detrimental to.lipolys. A better chip I think is fs312f. Make a video about it, and reply me.

[@benjaminmolnar3881]

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.

[@SineLab]

Yes, they should work, considering that they have the necessary protection features.

[@sanjaybatra6593]

which mosfet you have used ?

[@salemabo8147]

I thought i knew almost everything about the topic until I watched your video ❤

[@SineLab]

I'm glad that you learned something from watching! :)

[@YigalBZ]

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.

[@phillipkusinski6365]

Is it now possible to use the LIPO battery while charging?

[@xdZapo]

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)

[@SineLab]

I'm still working on those, I did a battery video in the meantime :).

[@monko1461]

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

[@Dragon21434]

Can i use the default 1 amp charge without having my 3.7v 3 amps lipo battery exploding?

[@vendettasnares]

What capacity? I've seen people recommending 1C as a safest option, but some say 2C is also fine. My question is are you in a hurry? Is 1h vs 30 minutes really makes a difference for charging battery for alarm clock that lasts for weeks?

[@GameAndJokes]

I have a question how can i charge the battery if the esp32 or the MC is connected to the usb cable and if it is disconnected from usb cable it should use the battery, i m trying to figure it out and it's getting really complicated

[@BilalInamdar]

Did you found the solution ? as i was also searching for the same. The thing you were asking is known as load sharing.

[@afg9104]

My project uses 5 volts for the sensor and the VBUS for 3 volts what kind of battery should I use?

[@SineLab]

You can use a LiPo with a boost up to 5V.

[@mudstrand]

Can the TP4056 provide enough power for a ESP32 WROOM-32 board? Can I use 2 18650's in a holder with the TP4056?

[@LiuEvan]

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

[@Brian_Of_Melbourne]

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

[@andymouse]

"essentially the same thing" is correct and they are "essentially" but the 'Lifepo4' can catch people out.

[@AlenHR]

@@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.

[@andymouse]

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

[@Alice8000]

"net loss" he says lol i love it

[@landondavid5773]

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.

[@landondavid5773]

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.

[@SineLab]

Thank you. It's good to hear that you appreciate the videos :)

[@Chimuraaa]

let people do what they want lmao

[@billshedd55]

Li-on and Li-po are not the same.

[@TimOsman88]

boost

[@jjones503]

Why buy off the shelf when you can diy for 3x the price! 😆 thanks for the video!

[@sultan7679]

that's a bad module in my experience

[@kadensmith5586]

What problems have you encountered?

[@heelercs]

Why?

[@heelercs]

Useless comment

[@USA-GreedyMenOfNoIntegrity]

Maybe it’s your error.
