So why did you disassemble it all the way to the cells? It seems like a whole lot of work for nothing when all you have to do most of the time is to get the battery out and charge through the discharge line at the battery and then apply 12 volts to the white plug.. The black and red wires after connecting the charger then the bms will start blinking red showing it's accepting a charge? Im just curious as to why you did it this way??? For me I let 4 of these scooters sit for 2.5 years and they all went dead into deep sleep mode so I was just waking them up

Some of the cells were discharged and some not. Applying voltage on the discharge lines might wake up the battery, but it will not balance the cells. Charging individual cells from the series will ensure that all cells were fully charged and the pack is balanced.
@mikejones-vd3fg2 ай бұрын
@@thecelldoctor8890 Yeah those cells that discharge like that are weak ones and proably bring down the rest of them by not being able to charge fully to 4.2, replacing one could bring back lots of capacity. I have an e45 i found in the dump with an error, turns out the internal one just wanst charged, because the external one wasnt making connection to it because it got loose. Taking off the external battery and charging the internal one fixed it but getting the external battery was the trickky part, i see I wasnt the only one with issues heh, i had to use a screw extractor to get it out, probably another reason it was thrown out, it looks like they also tried to get in there, eventually stripping it. Anyway i only get 12km range with this battery pack, sure its not going to be the full 22km like it was new but i think replacing a weak cell or 2 may bring it back closer to 20. So this information is very valuable thank you, even to build a new one from scratch, lots of good info here thanks.

Wonder if we can find its rs485 protocol so we can connect not-Huawei battery to the chain. Is it possible?
@thecelldoctor88903 ай бұрын
Well, the main issue is the bidirectional DC to DC, is not the protocol. Protocol can be sniffed in a few days most probably, but you need to provide 400 V DC from the battery and charge it from the 400V buss as well (bidirectional DC to DC), redo the BMS part as well to communicate with the other DC to DC. (It uses 2 DC to DC's until it gets to inverter). Seeing the complexity of the system, I decided to stop the investigation as it's not worth the effort. There are other inverters out there which work directly with low voltage 48V banks and BMS'es like JK BMS deepcyclepower.com/product/jkbms-smart-active-balance-bms/ communicate directly with them. I used Growatt 5000 offgrid inverter in one of my installs with a 15 Kw battery that we built and it works like a charm: deepcyclepower.com/product/48v-280ah-metal-box-kit/

Hi, it depends on the testing current. If discharged with less current, the cell will get discharged slower and have higher capacity due to low volt drop. It depends how the heat is dissipated when discharging, a lot of factors including contacts of cells if rusted or have nickel strips, environment temp can contribute to different results compared with datasheet. It also depends if the device have been calibrated

Can you post detailed step by step instructions from start to end that works so that I don't have $500 worth on paper weights.
I get to "Step 4: Build and Launch the App" and get the error "ModuleNotFoundError: No module named distutils"
Same here, did you solve it?
same ...
@@s3v3nlife I downgraded Ubuntu from 21 to 20 (or 19 i don't remember), but it worked.
Is it licensen to SW free?
Thanks for that - I dismantled a LiPo motorcycle battery yesterday and had similar issues to you - even down to a flash of the knife cutting apart the tape! 🎇😅 I wish I'd seen your video first - I damaged the casing so I broke mine for parts. But I might retrieve the pouches and test them more thoroughly to see if I can find the original problem anyway, and maybe keep good ones for the next project. 👍
i want donate but only have paypal .
Hi, thank you for your support! At the bottom of the github, there are 2 links, one for stripe and one for paypal. github.com/alex3dbros/megacnc
Is there a way to get it up again after it’s fully empty?
Disconnect the battery from the DC DC and use a 48V charger to get cells above 3V. While charging the bank, measure each cell one by one to make sure they don't get overcharged. If you have any dead cells in the pack, they must be revived or replaced.
Is this the ekick scooter c 20
The big problem of this battery system is the self power consumption. Value of 60-70W are normal, so about 1.7kwh/day of loss are normal! That's a lot more than other battery brands. Let's hope that the new Luna S1 will be better in this regard.
Honestly if that’s during sunshine hours, I couldn’t care less. But if that’s at night while it’s discharging, that’s a lot relative to the 5 kWh capacity.
Thank you for making this video--so informational/helpful. I hope to become more electronics savvy + self-sufficient. I'm looking forward to watching more of your videos!
You are welcome! Thanks for your feedback!
Why is this software not free with the purchase of the charger(s)?
The software is free, open source actually. But this image must be maintained, uploaded, pay for traffic. For those that mind paying 5 Euro, can watch the video on setting this up on their own on VM or Raspberry Pi
Great to see new useful updates! Hope to get more APP functionality soon. Would be great to manage projects, like delete old/unnecessary ones, swap the cells between them and also swap charger from one project to another. Also you could add chemistry presets to charger setup, I see there is a window, but only one choice. Keep up the good work!
Nice, and good job, I'll start testing and installing your Mega CNC soon :) Greetings from Poland
So why did you disassemble it all the way to the cells? It seems like a whole lot of work for nothing when all you have to do most of the time is to get the battery out and charge through the discharge line at the battery and then apply 12 volts to the white plug.. The black and red wires after connecting the charger then the bms will start blinking red showing it's accepting a charge? Im just curious as to why you did it this way??? For me I let 4 of these scooters sit for 2.5 years and they all went dead into deep sleep mode so I was just waking them up
Some of the cells were discharged and some not. Applying voltage on the discharge lines might wake up the battery, but it will not balance the cells. Charging individual cells from the series will ensure that all cells were fully charged and the pack is balanced.
@@thecelldoctor8890 Yeah those cells that discharge like that are weak ones and proably bring down the rest of them by not being able to charge fully to 4.2, replacing one could bring back lots of capacity. I have an e45 i found in the dump with an error, turns out the internal one just wanst charged, because the external one wasnt making connection to it because it got loose. Taking off the external battery and charging the internal one fixed it but getting the external battery was the trickky part, i see I wasnt the only one with issues heh, i had to use a screw extractor to get it out, probably another reason it was thrown out, it looks like they also tried to get in there, eventually stripping it. Anyway i only get 12km range with this battery pack, sure its not going to be the full 22km like it was new but i think replacing a weak cell or 2 may bring it back closer to 20. So this information is very valuable thank you, even to build a new one from scratch, lots of good info here thanks.
LFP is also lithium ion... lithium ion = rechargeable !
You are right
Nice! Ai pe undeva ceva date de contact?
Salut, da, pe deepcyclepower.com/
How did you make your M110 printer detected in the Powershell window with its Bluetooth / SN name please ? By default, for Windows & Mac M110 is USB only. (1min47 in the video)
Hi, make it print using the phomemo software first using bluetooth, then it will work on the pack calculator as well.
Wonder if we can find its rs485 protocol so we can connect not-Huawei battery to the chain. Is it possible?
Well, the main issue is the bidirectional DC to DC, is not the protocol. Protocol can be sniffed in a few days most probably, but you need to provide 400 V DC from the battery and charge it from the 400V buss as well (bidirectional DC to DC), redo the BMS part as well to communicate with the other DC to DC. (It uses 2 DC to DC's until it gets to inverter). Seeing the complexity of the system, I decided to stop the investigation as it's not worth the effort. There are other inverters out there which work directly with low voltage 48V banks and BMS'es like JK BMS deepcyclepower.com/product/jkbms-smart-active-balance-bms/ communicate directly with them. I used Growatt 5000 offgrid inverter in one of my installs with a 15 Kw battery that we built and it works like a charm: deepcyclepower.com/product/48v-280ah-metal-box-kit/
Is there a GUI/Desktop on this version of Ubuntu? How do I launch or boot into the GUI?
This version has no GUI. You can run a VM with ubuntu if you need gui version
@@thecelldoctor8890 I ended up using my Ubuntu desktop version and installing using your instructions. Thank you!
que te parece?
Can you tell me the battery orientation. Starting with the top right looking at the long bms board to start, working from left to right top to bottom. Then the small bms board. Left to right ,top to bottom, please. I took them apart without recording what was what! Thanks.
The Long BMS board has markings for each cell. Positive to negative and which cell number goes where. It's a 10S pack. I recommend understanding how series and parallel works first before redoing the pack. It's 10S 2P. Once you understand this, you will figure out how to assembly them back.
@@thecelldoctor8890 OR you could tell me which way they go saving me a bunch of trouble. But thank you for the help youve given me thus far. I dont want to cause you anymore trouble than I already have. So thank you! I get it, i have to learn the hard way! another $35 bms board will teach me NOT to get excited and get ahead of myself, and tear into a battery without recording what battery goes where. Thank you for the help you have given me. I have learned alot! Thanks for that! your really kind for giving the advice you have. Good luck on subscribers and likes!
Hey, what is this module that you have connected to the laboratory power supply and use to charge the battery section separately? 21:40 🤔
It's a PCB we developed. Can order one here: www.deepcyclepower.com/old/product/10s-battery-balancer-megabalancer/
hello, I have seen a good demonstration showing that the capacity computed by Liitokala (Lii4) is false, for a simple reason : the mesure is done while charging, it should be done from a fully charged battery. litokoa showed 3000 Ma/h while the real value was 2300, I will look for that video if you want the link (but it is all in french, you may be able to translate the sub titles) . IT is not at all a comparative video, the guy only needs the info to make a powerful battery for an electrication of a small motorbike 1970 50 cc ! (superb job and good explanations) . Best regards
here is the link, he used the liitokala 4 then an electronic charge to respect the cell builder test protocol : kzread.info/dash/bejne/nGihxsOom8izabA.htmlsi=RLUoHvM_EWWJeXwD&t=266 - I hope YT will allow the link
Hi, it depends on the testing current. If discharged with less current, the cell will get discharged slower and have higher capacity due to low volt drop. It depends how the heat is dissipated when discharging, a lot of factors including contacts of cells if rusted or have nickel strips, environment temp can contribute to different results compared with datasheet. It also depends if the device have been calibrated
@@thecelldoctor8890 Yes , I get it , the guy wanted very logically to manage the testing respecting the datasheet environment. Clearly the result showed as good a weak battery if measured with the Liitako 4. BOw you gave us a lot of work between the update and the new software ! All the best
@@thecelldoctor8890 " If discharged with less current, the cell will get discharged slower and have higher capacity due to low volt drop" is it the same when you regulate the "chemistry" to 0.5 1 , or 2 A ? the results differ (a little ?) Up to today I get similar results after similar cycles, tell me, if I have not enough power, do the MCC refuse the 1amp choice (my impression) ? BTW it is for discharge and for charge ?
I guess we can use standard inverter from different brands on the battery by removing the DC DC by dropping the voltage as normal 😢
Yes, that's possible, but you need to have a BMS installed to safely charge the cells as well. The DC DC has role of a BMS as well
Thank you for this amazing video. I got to know a lot from it. Very informative 👏🏾. So huawei is going smart by this hidden technology. I couldn't find the exact amp and voltage of the battery before watching your video. Count me in your followers now from Africa (Mali)
You are welcome! Thanks for your feedback!
I wonder if it would be possible to mount 2 wires and crocodiles for each external connector of the MCC pro (just to send low intensity voltage to batteries under 3 V without dismounting the cells and not passing thru the BMS indeed ? Thanks
If you connect 1 slot at a time, yes, can do that. If you connect multiple slots to different cells in that pack, megacell charger will get damaged permanently
@@thecelldoctor8890 Thank you ! Too bad ! I was vaguely expecting to use the balancing wire to send them a low current so the cells can begin to charge . But I do not understand if constant voltage or constant current is needed in that case. THe power unit you use in direct mode, do you regulate voltage or is it intended for fixed foltage and some not too high current max ? , (and those batteries have only 10 cells each ?)
@@thecelldoctor8890 hello, I was looking at your video on facebook where you state that you try to use non conductive pry bar. Last year I bought a zipped bag with many tools to repair cars external skins and other where plastic pry bars are useful. The kit was about 15€ and very useful to dismount modernTV (many of them have no screws). I will send you a linkwith Gmail if I find it now. Best regards
Hello, those are 3 interesting videos , WOuld you make me a 13S multi_ charger , I do not see myself building it on breadboard or the bords with many tinned holes But : you have 4 wire by every charging element ? ( may be if you give me the reference (making 4.2V x amps) from your alimentation ? I guess your BMS have a balancing part, but I do not understand as I did read there are 3 sorts of BMS, some without real balancing circuitry how do they balance then ? passively ? . Now I will have a look at your catalog in case I see you homemade tool ! I have one of those cylindrical batteries, un charged for one year but neww , not used . U8Nfortunately metal case with plenty of sillicon in it . I could cut the sillicon up to a point but the pack stay stuck , I will try with the air gun , but the heat will be dissipated fast due to the aluminium casing. THanks again to make those videos I thought that under 2.5V the battery begin to die and couls sie relatively fast...does not seem to be the case in the end . Regards
Good job ! It's way better than the previous app, I personally like this one a lot. Keep up the good work !
Thank you!
Thank you very much for the great teardown. I have already installed about 30 of these batteries, and it's great to see them from the inside and to see that they are well put together. Huawei says there is a dehumidifier inside the battery. Did you encounter such a part inside the battery? Would it be possible for you to do a teardown from the DC/DC on top of the batterytower?
Hi, Thanks for your feedback! I did not see any dehumidifier inside, there's something on the lid that looks like a fire protection cell which should pop if it senses fire to extinguish it. Or maybe I am wrong and it's a dehumidifier. I did tare down the DC DC Part off-camera for learning purposes, but It's too much work to be worth the effort of building that part to connect other batteries. I can look for the photos I got and send on telegram or whatsapp, visit deepcyclepower.com and can find my number there.
@@thecelldoctor8890 There is a fire extinguishing bag in each Huawei battery module, not a de-humidifier. That's why there are those 8x temperature sensors. There's also a battery optimiser inside each 5kWh battery. I saw it at a trade show where they had replaced the metal casing with Perspex.
@@kalbarriman The temp sensors are for the BMS and cell monitoring. The fire extinguisher cell will pop when there's fire present or goes over a certain temperature, it's not linked to the BMS in any way, it's standalone
That QZ software looks cool. ;)
:)) Yes it does. Thanks for making it!
I would be interested in a group buy.
Were are you from Michael ? In EU I can ship these kits with no problems
I am in the US... so probably not possible?
@@michaelcharge4783 I can talk with my supplier and ask for shipping price, I think we find a solution to ship to US as well. If you are interested to get the kit, email me at [email protected] with shipping details and I will provide you with shipping options and cost.
I just finished testing on Raspberry pi4 4GB ram running ubuntu 22 image. It runs great and it's a low power device that you can keep on 24/7. RPI3 did not work as it's missing some dependencies and processing power is quite low
hello , seems like a great job , a bit technical at installation time (but are not we supposed to know a bit of that ?) I have a more basic question : my main PC computer is connected via ethernet cable to the wifi server (that receive internet indeed) just tell me if it is basically possible to have the megacellcharger on that (w10) PC ? do I need a shell ? or buy a Wifi USB plug ? (see I am far from understanding !) actually no software on my laptop connect to MCC, or I have no IInernet access - Can MCC be used as a router ? . Sorry for the dumb questions, I hope you will have some time .... Best regards
Hi, If it's connected to same network with megacell charger, than no need for wifi. About the instalation, it looks complicated but is not that hard once you get through the virtual machine step. In the future there will be images for VM's and raspberry pi. But database is stored on that VM so I still need to teach people to use the console for future updates.
@@thecelldoctor8890 Thank you, yes I need to look in that Virtual machine use (I thought we where using at last one under windows, without knowing it !)
hi folks, does any one can install this app to ubuntu without gui? i am thinking to install ubuntu on synology nas drive and use.
It will work withouth any problems. I chose gui version as is easier for me to use
Good stuff! Waiting for the API docs :D
