It is really not often one gets to see some neat work at basic levels as people usually get carried aay by the bigger ideas and tend to forget the basic steps.

once low voltage tripped is there a way to get them "bms" active again? i got battery shows 0v on tabs but when i measure battery -+ it's 4.0v bypass bms, so bms must be tripped..

I think yeah you can use the old sony bms by connecting it with new battery cuz it just ok if there is 1ah difference (low or high) but if your new battery have more then that then u can't use, it may disconnects the power when you increase your mobile brightness either than that it works good I hope 👍

Use a resistor (1k) , connect it with the 2 pins which are id & temperature, but firstly you have to check the resistance of those two pins connecting with -ve pin of battery in series. And then you have to check out the pin which have a low resistance and then cnnt the resistor with -ve pin in series.

Bhai replay dena jo Aap ne Battery Tod diya Wo damage ho gai thi.......

[@DIYwithBatteries]

Ohh yes bro! the battery was expanded a little bit so i made a small hole on it, but now it's not useful anymore. Thanks for watching my video Bhai...

[@becool4142]

P+ and p- its ok. but what is other pin ???? please some one explain

[@DIYwithBatteries]

It's a temperature or a indicator status and simply a battery ⚠

[@user-rn6hz8pb9s]

You can bypass apple security for changing batteries by separating the circuit from the battery and soldering it to a new 3.7v battery 😉

[@raviingole1212]

Nice experiment bhai... kya tum is battery ka backup nikal sakte ho kya ? if 4 v dc led strip ispe lagane ke bad kitna time chalegi plz make video

[@DIYwithBatteries]

It depends on the battery capacity and also how much current that we draw at the o/p load. Thanks for your intrest bhai...😊. Sure I'll make seperate video on it 👍.

[@raviingole1212]

@@DIYwithBatteries 1 aur doubt tha bhai.. mine 4 v dc led strip 3.7 v mobile battery pe lagai to o strip 250 mAH current le rahi thi... aur fir 5 v mobile charger pe lagai to 2 Ah current le rahi thi.. yisa kyo bhai ?

[@DIYwithBatteries]

@@raviingole1212 if you add a 6v battery it takes 3AH may be! but the LED strip can gets heat so you have to use a resistor if you wants to increase the input voltage. Better Use 2ohms resistor for 3.7v Battery to connect a 4v LED strip. Because i used a 3ohms resistor for 3.7v battery to connect a 3w LED. Thanks for your great comment Bhai... .

O vídeo é excelente. Só não achei o diagrama, pois estou com problema de vista e não consegui ler o valor do resistor que vai à lâmpada de led usada para descarregar a bateria e nem a voltagem/amperagem usada depois para carregar a bateria com o protetor. Obrigado pela atenção e forte abraço do Brasil.

valeu cara me ajuda muito ;) e não deixe de assistir meus outros vídeos espero que gostem Haha

How much volt battery can be charged

[@DIYwithBatteries]

4.2v maximum

Very interesting, thanks. I think a voice explanation would be better than annoying music though...

Will do thanks for watching man 👍

Thanks, and my sincere greetings Everything is understandable, but what is the appropriate electrical resistance value. Thanks again and I hope for a response from you

Electrical resistance value Hm.... check out later you got point lol :D

You are freaking Genius. But there is no heat sensor in this Board. lol and they are mostly in laptops.

Question again: how to wire, when on the same time: charging while a load is connected?? Regards, Jan

[@DIYwithBatteries]

Yes! You charge it while the load is connected but the battery gets hot isn't it and the capacity drops too ¯\_(ツ)_/¯

Also, brother, if your this bm41 MI battery module can only take the 1AH 5v adaptor, in that case, can brother help and guide me like for example, what other battery module I can use for support 2AH charging? But anyway if I can use my 30,000mah li-polymer battery and solder with your this bm41 MI battery module, I also already VERY VERY happy and very much appreciated and thankful to you!!!! Heheheh

[@DIYwithBatteries]

It depends on the module which you are disabled from mobile or any other things.

[@snowy2875]

@@DIYwithBatteries Good afternoon to you, brother!!! you mean, but brother, in your expertise opinion, how do I know Which mobile phone has the most input charging battery module? Or the battery module able or not able to charge at 5v 2AH, is depending on the phone battery capacity I disabled down? For example, is it like, the largest phone battery capacity I disable their module down, should be able to hold 2AH input, and as for bm41 battery is only 2000mah, so, this bm41 module can only handle 1Ah power input?

Brother, you are the final last hope I have, and you are the only person who know all the answer I want, so, I beg you please help me for this question, brother can you explain to me in layman term because I stupid and not very sure about the eletric. Brother, I don't understand what this two means: I don't understand this two you say, brother, can please please explain to me in layman term 1) this module can handle only 1AH max and can "make sure to avoid 1amp loads" 2) so make sure to avoid more than 1amp loads What does this two means, brother please please help me!!!!!

[@DIYwithBatteries]

You can use it for any mobiles which can draw 1AH max... But if you use more than 1Ah load like example: LEDs, motors, or any other circuits. You can charge your Panasonic batteries with 5V 1Ah mobile adaptor and don't use more than 5V. I would like answer for your questions Buddy no worries. 😊👍

Brother may I ask, if let say I build a 20,000mah battery be it I use lithium 18650, or I use a 30,000mah LI-POLYMER powerbank, and I tear down, open up my 30,000mah powerbank, take out the 30,000mah li-polymer battery from my powerbank, and solder with your this battery module, can and safe or not? I mean if I glue 6 to 8 lithium 18650 behind my smartphone back case, is going to be very heavy. So I thinking, if I can use my 30,000mah li-polymer, instead of using the 8 x NCR18650B (Panasonic)

[@DIYwithBatteries]

@@snowy2875 Better to use lithium polymer it's a little bit thin.
