Make a Tesla 2170 holder/charger for this phone: kzfaq.info/get/bejne/p6ekpNypr8exp4E.html

This is a nice hack. Just as long as when you got the phone up to your ear on a important call the batteries don't decide to spontaneously flame out.

you did exactly what i've been trying to look into for months, love your work man!

Alternate title, strapping a powerbank to a phone

I appreciate how funny and creative you are. I can laugh at your videos and be genuinely amazed at the same time. Keep it up!

This is awesome!! Pretty straightforward, anybody with basic battery knowledge could probably do this. Would love to see a follow up video about your phone!

That's a great idea using the EVA foam to make the case. I'm definitely stealing that idea for some of my projects.

the most sincerely/funny explanation. nice work!!

I love that right angle design so much😂thanks for your sharing.

you REALLY should not be bending a lithium battery like that with pry tool, you should have used the release strips located where the BMS is.

omg dude haha. I wish my phone had this much power. Every time Apple comes out with a new phone they always say, 30% more battery than the last model etc, but the battery never really gets better lol.

Great project! I wish I knew the importance of these BMS boards before I threw away my PSP battery because it swelled (I didn’t have any electrical knowledge at that time). I imagine soldering that same PSP BMS board to a new and improved battery, from 1200 to maybe 5000 mAh that could last me a whole trip.

Mounts 5 batteries to the back of the phone... worries about the wire not being too conspicuous. Nailed it. 🤣

My Favorite Cambodian Teacher...... It's funny how 2 years ago I was researching info on my new Swagger 5 and last week I started researching info on my old iPhone 6 battery and your channel poped up for both... 😂😀

I have a smartphone that I got from a yard sale for 25 cents and it does power up and function, it does not charge by USB so I will be doing something similar with it. Seeing your contraption reminds me of the show Trigger Happy TV with the big cell phone guy. HELLO! NO I'M IN THE LIBRARY.

I have three phones. Two old ones but still functional and one I use in every day life. I still use them as it is good for remote use, camera from the house watching and stuff. Would love a battery like this one

this is the jankiest but coolest project I have ever seen on youtube. Congratz

Nice modifications! I've made my own "frankenphone" before with a battery bank circuit and an external momentary switch for the power button. I want to figure out how to add a scroll wheel on the side..

After charging a few times it may auto learn battery percentage,cool idea,did that trick for grandkids tablet after charge port failed.

I would imagine the phone would run much cooler without an internal battery

Some phones pull over 3A from the battery at startup. So if the phone doesn’t turn on after the mod. Try adding thicker wire from the battery to the BMS.

Lightning connector allows currents like 2amp I used apple 12W charger and it charge significantly faster. You may try that for convenience.

Truly Grateful! I am Truly grateful fir your videos and your inventions. I love it. Thank you, your helping me to open my mind. Thank you

Man, this is brillant! Even the motorola sketch lol.

Sometimes isopropyl alcohol will soften the glue holding the battery in. Use a syringe to dribble some underneath, let it work, pry a little, dribble some more, ...

Impressed and appreciate your efforts. Just keep away from your head due to radiation

I love this mod but it would be a lot practical if you would have installed a flat pouch battery instead of individual 18650 cells

it would have been nice to see you use shrink wrap for the battery pack, but it is still cool.

Very cool. I actually thought about this…. Nice !! And it‘s actually quite easy. Is the charging voltage of lipo and lion the same?

Pure genius. I never thought of this before. Funny, Apple keeps making their products thinner, yet many would prefer bigger higher capacity battery. You really should market this product upgrade! I am definitely trying this. Thank you.

This phone can easily become a disaster smartphone when rescuers can use it without worries in the disaster area. Good Job!

Nice project,make more this please.

Great hack. You are a man after my on heart. We think a lot alike. I enjoy your videos.

very creative and funny. liked it very much

I noticed that you put separators between the batteries under the nickel to prevent shorts would of liked if you had mentioned that. You could of put a knot using the wire just before the exit of the mobile to improve the accidental wire pulling. Great project and thanks for sharing 👍🇬🇧 My battery is starting to discharge faster so this is a possible project for me if I can do the same with my pixel 3.

Nice man. Also thanks to the YT algorithm for suggesting me the video

damn man it looks pretty cool for me :D did you really researched the airport laws for this? you are crazy man and I like that 😁

since i was little i always does this mod, to almoust all my phone, i done this to an iphone 6s, but i had the same issue with the battery indicator, (the battery health never get up of 77 % so, for some reason it always go dead fast even when the baterry was at it 70%) so y used the bms of an genuin battery and it help me alot.

after using the heat gun, try to use some IPA (Isopropyl Alcohol) to ease the extraction of the battery

epic adaption. maybe theres a way to 3g print a new back for the iphone thats more chunky so u could have the battery inbiult under the logicboard

Apple charges there battery to a much higher voltage, i measure it charges to roughly 4.4v which would damage a 3.7v nominal battery like the ones you’ve used but Apple uses 3.8v or higher nominal voltage cell that’s also the reason your percentage is in accurate

Nice mod thanks for the idea

The sticky on the batteries you can pull out if yoy grab ahold of the ends and stretch em off.. easy if can grab em..

I need one of these.

looks like a battery with an extra phone strapped on its back video title should be : i attached a phone to my giant battery pack

Nice project

Gooood work. I have in use Samsung a12 with 15000 mAh, 10000 mAh slim battery adapted from me. 3 hours workig for connections and design and my phone resist away from socket long time. After 3 days , normaly use, my super battery level is 74%. Real level, because Lithium modules is conected in paralell under BMS, with slim wires. Charge my phone with native 15w system in 6 hours after night, and i used original external battery case in my "slim" design. All the best. I have a one little monster phone and is ok for me. I tought i was the only me with such an idea.

The dynatac 8000 was produced from 83 to 94… 1973 cellular service wasnt even available, prototypes were being tested in very limited areas.

When I go through airport security, it looks weird 🤣. By the way it’s awesome 👏

I think u could use it as a jump pack to start the plane u r flying in. No APU necessary. Really cool!! U told us one day u would tell us a little more about yourself. Mystery man. Phantom engineer. 😂😂

You got a sub from me. Unique. I feel like hard days are coming.. where we will have to be self sufficient. Projects like this might help me/us

Thats crazy :) i love your idea. Hope one day the battery will not be charge any more :)

I like that 2 months on one change 😆

Excelente vídeo e trabalho, para um protótipo em beta há muito que melhorar, mas garanto que há aplicações para este aparelho, imagine ir para uma viagem em lugar remoto e não precisar carregar o telefone, ou ir para áreas em guerra. O mercado é gigante e as aplicações para este formato de aparelho, hoje você fica carregando em um powerbank externo que perde em elevar os 4.1v para 5v e tem que fazer várias recargas. Obs.: a medição da bateria tem que ser ignorada no cel, pois está calibrada por software que acredita que tem a célula original e supõe seu gasto pelo tempo, talvez tenha que incrementar um micro voltímetro amperímetro e wattimetro na saída da bateria para se ter uma ideia real dos rendimento e eficiência do conjunto packs baterias... Parabéns pelo projeto... e viva o compartilhamento...

Good job

Wow that is really nice please can you do a video on HP Elllite book2 laptop

I think that tape will release if you pull and stretch it out

Will the iphone detect the State of charge after a few cycles? Isn‘t the bms programmed to the original battery capacity?

Hello. Wouldn't it be a good idea to install a charge control chip in the batteries to prevent overcharging and overdischarging? that would make that even if the iPhone tries to charge it above the voltage it will not allow it. And don't let the battery cells go below a certain voltage either.

I wish I had that phone that would fix my battery problem

That was an insane project lol

i did tried to mod my phone too.. thanks to this video...

I've tried this idea on so many phones even bigger battery packs, but charging percent doens't show well, connecting batteries in parallel definately increases the capacity, but it disturbs battery charging algorithm Designed in the Phone firmware, and doens't perform according it's capacity, discharging levels never show uniformly, If someone want to do same, needs same capacity, same quality, same voltage levels, same charging cycle, same sizs of battery in parallel for steady performance.

17:36 could be that those 2170 cells can only Go up to 4.2v when the original battery can go to 4.35 volts and the bms is not expecting a huge battery so the capacity meter will be inaccurate for a few charge cycles

I am not the only Wierdo in this world kkkkkkkk we are many. From Zimbabwe wth love brother keep up the good work😂

Epic dude!

i still have my iPhone 5 running on Samsung battery from around 2015 but the iPhone itself is having a problem with the original or none original battery it only takes 8 hours idle or 3 hours of use only even with a 2500 mAh battery its the same before it i use the same trick on an iPhone 4 since this phone had no faults the battery would stay for maybe 7 days straight but this iPhone 4 needs a screen

Great video, nice humor;-) Man from the 70..

Why won't you also install a powerbank bord into the external cover that u have made for the battery... So it's More easy in use

Mobile battery low voltage cut off is 3.2v - on 3.3v, meanwhile the tesla or 18650 cutoff is 2.5v.. On rooted android phone you can edit battery capacity number so it'll display real percentage..

To get accurate battery percent you could have programmed the bms so that it clear it's battery data already baked into it.

phone battery are li ion but a little difference than your battery, orginal battry is 3.82 v nominal voltage with 4.35 volt full charge, you have to change your bms or your batry will ruin or burn from over voltage

Did this few years ago to my phone, my classmates thought it's a bomb when I take it out.

Great project 👍👍👏👏

"mad asian math skills" Made me chuckle. Thanks!

that a scary battery pack to have lol, imagine it shorts Hell of an explosion lol

"GUESS WHAT?" DOUBLE SIDED TAPE!

Also comes in handy when your car doesn't start in the morning. Jump start your car.

That's good work bro👍🔥.all you need right now is a 3d printed case

I wish that the procent displayed on the phone to be accurate, maybe it's the BMS? I think a BMS from a new battery will be much accurate but i'm not sure🤔

I’m sure they just LOVE this phone when you have to go through TSA at the airport! 😂 I have ALOT of crazy DIY electronics like this and every single time I fly with them they go through all my stuff, constantly looking over at me like “WTF IS THIS?!” Sometimes they’ll even call their fellow TSA agents over to show them all my stuff and they all have a good laugh together before finally waiving me through. I wonder if my experience would be any different if I had a different skin tone or style of dress🤔

Man you should put a Fan or some kind of thermal separation between the phones and cells, the heat is gonna kill the cpu

please answer, did the phone restart randomly? can u really test with youtube playback how long can it get with continous usage. I've been done the same thing long time ago using iphone 4s, it keeps restart randomly

Maybe the percentage display isn’t accurate because they aren’t calibrated. I heard that by charging it and discharging it a couple of times, the board will learn it’s capacity.

I can use my sonim xp8800 7 hours screen always on and after 4 years of use. The battery quality is very good i love my sonim personally and the same for my moto e 2020 7 hour.

Bros phone finna last a lifetime

Im speechless 😳

Jip did the same thing to my old android phone didn't fit in my pocket but every time I took it out of my backpack people just starts running like it's a bom and that almost got me arrested so now I only use it at home 😂.

So I guess it can be called a mini tablet now. And since it's an older iphone, the girth can be sort of justified. The TSA people are quick to point fingers :( My aunt lost a new apple laptop to them because she covered it in black satin material so it wouldn't slide on her lap while typing. Never got it back. $2500 down the drain. I probably would have just made an external enclosure for the batteries and spray painted the thing to look like the iphone's shell. Then double-sided tape it to the phone, or magneted it as well as include metal terminal ends like inside the original internal battery for simple removal.

U gotta edit some stuff in the system settings, cause it's not an official battery and especially not the same capacity, and for that u'll need root. Not sure if u can do so on iphone, but not that hard on android.

Hello there buddy, Now you gonna have iPhone battery for day’s 👍🏻

My new samsung phone came with 6000mah battery & gives 13-16hr screen on time basically goes on for 3 days without charge. The older honor 6x had a spicy pillow and also the screen cracked so i only use it as a webcam for my pc and so have this same exact mod done to it but with 18650 cell holder and 2100mah generic china battery cus the bms board is made for lithium hv cells which is 3.8v nominal and 4.3v fully charged so it overcharges the 18650 but it has been like this for 2yrs now and haven't exploded 💀

Wasn't it easier to connect a power bank?

Your phone looks like its half-unboxed on purpose..70 days without charging..thats crazy 😂😂😂

Nicely done! Could that batterypack be used on my old Motorola international 3200? It has a large battery "box" that your batteries could fit inside?

PRO TIP u can use older phones pouch cell battery - they are way smaller than 21700 (21700 is high output cell) then u can get 2-3+ times more capacity in older phone with only adding 5-6mm of the thickness

又厚又重，直接換新電池🔋

Very nice 👍

That looks like a bomb drop that enough times it will be

Are those the tesla cells you salvaged? How did they recieve caps on positive pole? Have you tried spot welding tesla positive no cap button pole?
