I would have recommended putting a small gap or insulation between the battery BMS and the 18650 batteries. I have a similar BMS, and when the balancing mode is being activated, the resistors heat up a lot. It would be wise if such heat source isn’t in direct contact with the batteries itself.
Yeah there's a few mistakes he made in making this pack but overall it's a good DIY project for the hobbyist. BMS does heat up especially when charging and balancing the cells those can get very toasty it being right up against the cells is not a good idea.
Nice build, but it's not actually 70,200mAh. It would be 70,200mAh if you used them all in series (3.7V 70200mAh, 259.74Wh). However, since you're using a 3S9P pack (3 in series, 9 in parallel for 12.6V) you only have 9*2600 = 23,400mAh capacity, but the energy is the same (11.1V 23400mAh is also 259.74Wh). So might be a good idea to use Wh instead of Ah with multiple cells in series.
All in parallel when you quote "70,200mAh if you use them all in series" it's probably why they sell ebike/escooter batteries with 100,000mAh when there about 10aH because the translator doesn't know the difference and not done his research
Doesn't connecting it in parallel give it more current thus more Wh too? If they were all connected in series you would need a bigger BMS and it will have a overvoltage for that board. Learn more about batteries and how they multiply.
between the bms and the batteries use a thicker cable, in the worst case you could start a fire by consuming too much amperage, it would also add a bit of dissipation to the BMS, it can get quite hot
Hahaha. not a 70200mAh. This is 3 series x 9 parallel power bank. (3 batteries in series x 4.2V per cell = 12.6V) (9 batteries in parallel x 2600mAh per cell = 23,400mAh capacity)
this is why i don't like measuring capacity in Ah. He got the 70,2Ah value because he just added all the capacities together all of the manufacturers do it just for marketing if you calculated the capacity in Wh the value would stay the same no matter how he connected it. if you calculate the capacity of the power bank he made in Wh you would get 252,72Wh (3.6x2.6x27) which is still a lot imo
You don't need 12 v to charge a phone you just need 5v , the rest of the voltage also adds to the capacity with conversion losses. What you're saying is true if you use it only as a 12v battery.
Solar powerbanks are possible. But the efficiency for the panel size is not great so if you want to not charge for 3 monts then you need a bigger solar panel.

It looks like a nice build Great Job, but I’m just a beginner and maybe that’s why even if I slow it down or pause your not making it easy to see how your wiring the build I mean it’s obvious you know what you’re doing but I thought you was sharing the build. I want to try the build but don’t want to get stuck at the end. Plus you didn’t even mention the charging plug you used at the end nor is it in the supply list.

I have 5 batteries of 18650mha 3.7v and I want to make a power bank to charge my cell phone I can use these batteries to make this power bank to charge my cell phone ?
Hello and nice video 👍 i try made it this batteries with more capacity 18650 battery high quality 19800mah 3.7v 18650 batteries li-ion rechargeable battery ... Its ok i go if i made it that battery ??!!
Hello, sorry for that power bank, which module is recommended to install to put a solar cell in it and what capacity would the solar cell be so that it charges the batteries and if it is not too much trouble, send me by email the diagram of how to install the solar cell and the rest I would appreciate it very much, thank you in advance, greetings✋✋✋
From years of doing these diy works. You just get one by one when you need it. After a few years, you would pretty much have all the necessary equipments
This 70200mah written in the title is incorrect, I know that there are people who will say "it's equivalent" well, then use the universal unit for battery capacity equivalence (Wh) which in the case of this battery is 260Wh, it doesn't matter if it was mounted 1s27p or 3s9p would be valid for both cases, but not mah that each case has its capacity
Those batteries are labeled in mAh in battery capacity, 2600 mAh each to be precise. Try buying 26650 lithium-ion batteries and see if there is a Wh label there.
@@racexine to see the wh, just multiply 3.7 by the capacity in mah per battery, in the case of the battery in the video it is 11.1 x 23.4. Always use nominal voltage
@@WolferAlpha I know that. I'm just saying that mAh is the standard labeling when you're buying li-ion batteries, so the title of the video is not actually wrong.
@@racexine so explain to me how mah is added when connected in series, Wh are added regardless of the connection and mah only when connected in parallel, so yes, it is wrong
@@WolferAlpha It is added when you're using a charge controller. Try discharging 2 pairs of similar batteries at the same time, 1 in series and 1 in parallel. Use a charge controller and limit the setting to 5 v 1Amp. I'll tell you, they'll both lose their juice almost at the same time.

Ok now get lost
i agree. A bekalite/hylam/teflon piece of 2 mm thickness will do the job. it does not get heated up at all.

That's alot of voltage from those lithium batteries, nice job👍
Only 12 volts. Some are connected in parallel to last longer and the packs are connected in series to step up the voltage. Check the multimeter.

he should have written capacity in Wh
I doesnt matter how he connected the batteries since he is using a module that converts the output to 5v.
this is why i don't like measuring capacity in Ah. He got the 70,2Ah value because he just added all the capacities together all of the manufacturers do it just for marketing if you calculated the capacity in Wh the value would stay the same no matter how he connected it. if you calculate the capacity of the power bank he made in Wh you would get 252,72Wh (3.6x2.6x27) which is still a lot imo
You don't need 12 v to charge a phone you just need 5v , the rest of the voltage also adds to the capacity with conversion losses. What you're saying is true if you use it only as a 12v battery.
By your calculations 23000 mah x 12v ÷ 1000 = 276 wh (actual capacity)
Now for 5v , 276wh ÷ 5v = 55 Ah or 55000 mah capacity.
MANTAP 👍 SALAM dari INDONESIA 😘
Such a clean work ❤
Bonjour de France. Très belle réalisation... et très utile lorsque la famille vient à la maison ^^
De Lyon, France, correct, le problème est d'obtenir les adaptateurs pour pouvoir les créer
Nice, hope you are going to make solar power bank with more capacity. Very interesting and people.can save the mother earth.
Solar powerbanks are possible. But the efficiency for the panel size is not great so if you want to not charge for 3 monts then you need a bigger solar panel.
This is extreme, salute man.....
Nice project, I love it! Good job bro
Be sure to do the unboxing and review of S23 ultra when it comes out
At the end is that the charger you plugged while still charging, meaning it would also work as UPS?
Great job bro ! as always.

Hello friends happy 🙋♂️❤️🙋♂️
Always curious what is it with the pinky nail ?
One thing to ask the 4 usb board can it charge with 120 watt hypercharger or 67 watt turbo charger?
Wireless charging ka fayda kya hai jabki usko ek hi jagh rakhna padega. Usse acha toh wired wala hai jitna lamba wire utna dur move kar sakte
For sanding u are using dremel or ingco
Great Video, Great Build, Awesome!!! Please if possible share links for the parts! Thank you in advance
There is no gap for the batteries in between. It will overheat. Eventually melting the interior.

No fans, over surge protection or heat sensors. 100% safe
