I might change the BMS with a better one for my electric longboard. More updates on www.electronoobs.com
Want to help my workshop: www.patreon.com/ELECTRONOOBS
Thank you so much!
Are there no better cells? My phone has ~4 Ah and is less than half the size.
Edit: do something with this supercapacitor recuperation technology. There is this YT dude with a capacitor bank as a car battery.
you should show testing
For the powered skate brotha you want high discharge capable cells, like from a cordless drill battery pack. Those BMS are “usable” but you’ll have to manually balance the cells. I can hook ya up if you want more cells, love the videos and hit me up if.
I can send you an SBMS0 when will be available if you are interested. It is open source but a bit of overkill for such a small application. You can see details about the SBMS0 on my current Kickstarter page www.kickstarter.com/projects/electrodacus/solar-bms-and-digital-mppt-for-pv-electricty-and-h
Please make a BMS.
Really nice work, dude!!! Looking forward to the long board video! 😃
Nice video my friend. One small tip : hot glue is not good for heat dissipation... Try use some specific adhesive or maybe a thermo conductive paste. Keep it up friend
You have made many of your videos from ideas from other ones on this site... And that is great! Thanks for everything, hopefully we will get to develop the future by sharing everything we can
As always another great video. I am planning of making my own homemade board. This is a helpful video. Keep up the great job
Very good work! I built an electric longboard, the best way to do it, is a brushless hub motor (or two !). I don’t know if you are thinking about it but it will save you money and time. I had to create an heavy structure with a lot of 3D printed parts to use a common brushless motor and to get something reliable. Also, it is not possible to get a strong 3D printed pulley but you can order one on the internet ;) I am looking forward to see yours !
I always like your projects and also deserve . . .like you bro keep teaching usss
Thank you!
Hi,
The discharge connection is also via p+ and p-, connecting wires to batteries will bypass bms
Thank you. If my longbaord will require more current I might bypass the BMS for the discharging process and control the voltage with an Arduino. Not sure yet...
Electronoobs yeah the p+ and p- terminals are for powerIn and powerOut :) so charging and discharging. Great tutorial love your channel.
Felicidades tus videos son los mas documentados y su aplicación mas sencilla para las personas que estamos iniciando este tema, gracias por tus videos. Saludos.
Dear, Friend. Could you make a tutorial about v-usb and midi on atmega328p? Thanks
Very nice video man. Big like! I'd like to see a esc driving a car alternator, on a bike or something.
Nice 👍 pack.I think that large shrink tube is used to cover the whole package that is much easier than aluminium plate.
Is your wiring diagram safe for diy bluetooth speakers? Or should I use P+ and P- for discharge?
VESC for FlipSky is Best! Waiting to review FlipSky VESC. Thanks for video!
Thanks for the video!
Does it has any over discharge protection??
I want a lithium ion battery pack with 4 batteries in parallel.i have a tp4056 with a inbuilt protection circuit for charging.Would it be possible to charge this 4p battery pack with a single tp4056 or should i charge each of them seperately.
Hey great video. but i'm curious, it didn't look like you were discharging through the BMS, which means you wouldn't have any protection like over discharge, over current, etc. I had a setup like this on my mountain board and I just used the ESC's low voltage cut-off. But if I had the BMS wired up proper as well I think it would have been better.
Keep up the awesome stuff!
My plan is to bypass the BMS for the discharge to have more current and control the voltage with the Arduino that I'll be using to generate PWM signals.If not, the BMS I think has only 10A discharge protection and I need more. Is notrecommended to do that but lets see what will happen. Thanks!
Hi sir,
Please tell me
Can I use multiple tp4056 charging modules for one lithium ion battery?
Excelente video, muy entendible y entretenido. Muchas gracias.
Hi sir. Is there any software or application that can monitor this battery when it charge and discharge instead of using battery indicator...Tq
Hi There, can i charge the pack while load is connected (load is live/active/running), i am planning to use readymade 3S1P or 4S1P battery pack with relevant BMS circuitry.
why you connect the bms to the negative of the cells?? 06:38?
hi,electronoobs.does the 6 series bms board can do 3 parallel battery pack?
thank you, for your great work 👍🏿
Hi, where did you get the nickel strips and are you certain they are pure nickel? Description has different products than what you show in the video...
To reinforce the case you can add some ribs that would fit between batteries on the bottom of your board and connect that aluminium plate to them. It will make it much stiffer and protect batteries from getting squished in case you land on something.
excellent video !!!
The best part of this video is when you start explaining that how to charge the battery pack.
❤ EXCELLENT VIDEO MY FRIEND THANK YOU FOR SHARING YOUR KNOWLEDGE
is that okay using a 15A rated bms when your battery pack current output is 60A? since you connected 3x 20A batteries in parallel
Question: Can I connect two bms 24 to get 48 volts using one charger, bms 48 v is not available in Egypt thank you
On section 6:39 , when explaining the battery protection, is that a mistaken labeling of the b1 for reference bat 4.2v and b2 for reference bat 8.4v? I'm confused with the blue wire as 8.4v instead to 4.2 v, since the blue wire is referencing the first battery.
Anyway, good projects !
Can you please make a voltage booster circuit using IC 555 to charge 450V capacitor bank .
I think you might wanna get solder wires from a different brand. It looked a little bit hard to walk with. Great vid by the way!
Super video 👍 very Excellent
So this bms is for 6 pack of 3 cells each or 6 cells?
do you use the same connector for charging and discharging?
No. I have 2 different connectors as in the schematic and I bypass the BMS for dischaging.
do put a skid plate other than diamond plate, to protect them from damage
Lol i was trying to make this type of battery, but i fail. Hopefully you post this video ^^
You showed b4 and b5 connected to the negative terminal instead of positive terminals @6:36
Nice
Why no BMS lead to battery #4 ? @ 6:39
Hiw to charge corectly?
Muchas gracias
How much this battery pack cost?
can it charge 25.2v charger 1amp charger?
I have a scooter with a 20v motor that was run by 2x 12v sealed lead acid batteries in series. Is this ideal for my scooter?
What type of motor?
@@ELECTRONOOBS I think a brushed motor that came with the scooter
I would make 7s. You get litle more speed. And atleast 4 cells parallel to get range and torque. Some peoples say that is not good to use lithium batterys whit brushed motor, but that is bullshit. I have brushed motor in my ebike and it is working well. I have 2pcs 10s4p 36v batterys now, and I'm going to update those to 13s.
@@ELECTRONOOBS Ok I have the details. It's a MY6812 24Vdc 100W brushed. unitemotor.com/index.php/Home/Index/product_detail/id/178
Any suggestions?
good
Please make video on pic microcontroller
Also, youre using a 120A rated esc which is way higher than your battery 60A max current. is that safe? i thought your ESC current rating must be lower than of the battery current.
Hi. Using a 120A ESC with 60A battery would only be a problem if the motor would draw in any case more than 60A. But for this proy maximum current was around 10A. Also using that 10A BMS was an error and I had to remove the output current limitation on order to work...
@@ELECTRONOOBS alrighy, may i know what was the motor that you used that is lower than 60A max current?
its nice
Why don't you choose 2 Li polymer battery for 25v?
Li-ion batterys have a better density so they are smaller and not so heavy for the same capacity.
GameArea158 thanks
hi bro can yoj make lipo battery change ,? 2,4,6 pin changer this 2,4,6 pin changer .......please bro can you me to make
Awesome video sir
Request to you please make cheap Chinese 5s bms reverse engineering circuit schematic diagram. Please......
Im your new subscriber from instagram
Please make an Arduino setup, to display the voltage levels of different battery packs. Like lithium 3s, 4s etc.. It will be fun to see the battery level information in voltage, percentage or graph in a color OLED or color LCD display. BMS with this feature costs a lot! But this should not be a BMS, it should be able to work with any battery pack, which already has BMS.
hello freands plase diy esc and bms
I don't understand the banana part. Do you eat it while riding the skate board, or run over it with the skateboard while exclaiming "Victory!"
fpv.air-war.org
Awesome Video.....But i think there is a mistake that BMS is for 5s batteries and you are using it for 6S batteries.
6:19 it is a 6S BMS
Its a shame that countries around the world cant get those battery’s shipped to there country.
just clicked on your link and they cant send to new Zealand
What with the Bannana
I builded my ebike battery out of used cells. It is 10s4p 36v about 8ah. I dont have bms, but I measured cells voltage today after 2 months riding dayly and they were exact same level all. I soldered my cells whit nikel plate. Only cost was 0,5 euros for nikel plate and 5e for wires.
Make a diy spot welder
It would be better if you 3d printed a case for it
Next project t12 soldering station + hot air gun in one box
Yesterday I built 7s3p battery pack with 18650 😅
Sir plz see previous video & see my comments.. I still waiting for your comments
Plz diy homemade lithium ion battery simple smart charger
Please Comment Electronoobs
.
Please don't overlook overheat protection.
wow genius boi✌ it was awesome.
and
im trying to run my pc using 5v mob charger. so it will be environmental friendly. and mainly it will reduce my electricity bill 😓🔫.
I'm afraid that won't work at all. First off, you need the correct voltage for it to work. And the most important of all: even if you could get it working, it'd a futile effort as the power used by the computer will be exactly the same.
Great Video, but i only have 23 subs
:(
یا الله
You are discharge the battery without the BMS take action, aren't you?
Why you use banana in every Video?
OH so you're making 6 baterry packs of 3 cells each but yet you call this 6S ?.... good luck in your future endeavours, im out of here...... hint : 3S6P
Question: Can I connect two bms 24 to get 48 volts using one charger, bms 48 v is not available in Egypt thank you
