The 100 Balance BMS with 1A Active Balancer and Wifi. A true JK Competitor?
Вставка
- Опубліковано 26 бер 2024
- In this comprehensive test and review, I'm sharing my experience with the 100Balance BMS. I saw this online and wanted it in my garage for testing. This Daly-style BMS has a 1A active balancer, Bluetooth and Wifi, RS485 and CAN communication for your inverter and it can handle 100A. First thing which came to my mind was: 'Do we have a JK competitor here?' All the specs and features looked good, but once I started testing it, it quickly came clear, that there is only on BMS-King...

Andy, thank you for your sincere and honest reviews of our products. As a new brand, we are in great need of such professional and sincere voices to improve our product design and quality. That's why we reached out to Andy and asked for a review.
In response to your suggestions, we will upgrade our product and send to you for test again.
For more information about how to use our products you can click on my icon to go to our homepage, and if you have any suggestions you can leave us a message. We welcome any comments that help us improve our products!
You need to fix the balancer shutting off at 3.5v and only turning back on at 3.45v. I raised level 1 high voltage in the PC to 3.6v but the release is still 3.45v and cannot be altered. Let us know if you make a firmware update for everyone.
What a superb response. I am getting an active balancer for my escooter and will keep you in mind, as quality companies only exist when they take fair criticising and respond accordingly.
Wow. This manufacturer is thanking the reviewer for criticism and added perspective. A very rare sight indeed.
@@evanmayer744 As a new brand ,we are care about all of voice of customers. There are not perfect product in the world, but we can do better.
Please update the firmware and pc app to website. I recently purchased 2 pcs of this BMS. I wish I get the latest firmware with bug fixed.
There's something very symbolic about Andy dismantling the BMS on camera while he describes its flaws. He dismantled it practically, while dismantling them commercially.
I can only share what I test and experience and this was not the greatest. I hope they can send a fw update soon and I can retest the BMS.
@@OffGridGarageAustralia I'd say that as far as story telling goes, the video was amongst the most well done I have seen from you. Perhaps the way you did the end sequence wasn't intentional, but it was, in a way, artistic.
UA-cam videos like yours aren't refined like a TV show, but the way you told the story matters. (I work in TV and used to teach TV production.)
@@BobHannent I take this as a big compliment, thank you very much.
During my summary at the end, I disconnected everything again and packed it back in the box to visually symbolise my verdict and conclusion about this BMS. You have an eye and understanding for that, which is great. Not many would have picked up on that but still, it transferred the message across to them and helped them 'feel' what the verdict was about.
I'm also a big Casey Neistat fan and analysed most of his videos in terms of story telling. I have learned a lot from him but it's hard find my own way. I'm still at the beginning of that and learning with every video I make.
Thanks again for your feedback. It helps me a lot🙏
@@OffGridGarageAustralia really ? Do you really believe that this will done by a fw update ?
I doubt that any chinese company will meet your expectations within 1 fw update. It will take ages and update over update before you might see the light on the end of a tunnel as we had seen so often for example neey needed 4 product iterations more or less till you seemed to be happy. Most chinese will not have the endurance to do that over and over again.
I love, how you put everything back into the package 🤣🤣🤣🤣🤣🤣🤣🤣
Hahaha, was the best thing to do for the verdict at the end😄
Andy!!! einen großen Dankeschön für deine Videos . Einfach super!!!
Gerne!
i love these review videos Andy! Keep it up, this channel is my FAV! SPAT
Thanks, will do! More to come!
You are always the best!!!! speaking of jk, after a faulty BMS when new which was replaced with an identical one (B2A8S20P-HC) I installed it on a 560ah 12v battery and connected it to the inverter I connected a 270ah load for about 2 minutes.. ....Perfect! jk great bms
Nice, JK works still the best, I would say. It's not perfect but they are working on it.
Great review, thanks Andy. I've noticed for a while now that Dally has been presenting itself as the best and most expensive, but your review revealed the reality of their problems and misleading information. I completely agree with your assessment, especially regarding the 2 frogs. Thanks again!
Yeah, really a bit disappointed with this BMS. I hope they can improve with a firmware update soon.
Beer! Thank you Andy. Interesting to see, that you still grand this BMS two frogs. Personally, I would give this BMS just one, since it seems to fail at it's very basic tasks. :D
I had only one frog at the beginning, but the Wifi and easy firmware updates seem to be good features, so... 🐸🐸
Very informative and helpful
Thanks.
Thanks Andy, as always, love your work.
(Still watching the video, but at this stage it looks like yet again, it’s JK for the win. Mine have never missed a beat.)
Yep, JK for the win!
Thanks Andy - great video again. Request: Can you do an overview of the EarthGuard unit. We don't have these in South Africa but I think it would be a great addition.
That would be nice, some of us don't really know what it is.😅
It's mandatory here in Australia for new systems. The sparkies put it in with the solar upgrade last year.
I explained it her ein this video during the installation: ua-cam.com/video/SRKCzAO07P8/v-deo.htmlsi=IWXT6JHzlHKk62LL
great video again! DIO means Digital In/Out
Ah, right, thank you.
Love watching your informative reviews, I'm quite sceptic about 1:05, I mean really. I would have mentioned the latest Seplos V3.0 BMS which thanks to the latest firmware updates it has an optimal active balancing features. (they're the real winners = JK & Seplos).
Seplos V3.0 has some serious flaws. It is actually worse than V2 of their BMS. I can't even download the latest FW version as my computer deletes the file immediately due to a virus found inside the Zip file. Do I need to make more videos about that?😄
@@OffGridGarageAustralia Hi i’ve sent it to you. Unfortunately I’m still waiting for my two vertical Seplos v3.0 to arrive. However I remain confident that this time with their latest 2A balancer they will not let me down.
@@EF-Electrics Their 2A balancer is unmanaged though and runs all the time if cell voltage is above 2.9V and deviation higher than 50mV. They never offered my this balancer for testing because they already know what my answer would be.
Good luck with the V3.0 BMS, hope all goes well.
@@OffGridGarageAustralia Thanks 🙏
Thanks Andy
Thank you Wayne!
Andy, I learned something while tinkering today - When you put a small fan on the passive balancer resistors the rate at which they bleed balance vastly improves - I mean 2 or 3 fold - I guess surface mounting resistors run hot and their resistance really ramps up making them bleed far less - I expected some improvement but it was way beyond expectation - easily capable of keeping large 100a cells in balance - I used a small 5 v fan.
Hmm interesting.. now to add tiny heatsinks and thermal paste on them :)
Nice thanks for sharing
What passive balancer was that?
Passive balancer...🤔
I'm sorry but that cannot be true. Passive resistors don't change that much with temperature. Typical thin film resistors have a TCR in the 100s of PPM. Even if it was 500PPM (parts per million) a 100C temperature rise would only increase the resistance by 5% which the current would only decrease by 5%. not 200% to 300%. what you might be seeing is the BMS monitoring the temp of those resistors and it turns them on or off based the temp. So a small fan will keep them cooler so the BMS will keep them "on" continuously vs cycling them on and off due to temperature.
Beer! Thanks for another great video :)
Thank you.
Thank you. Ive looked at these many times but always just bought JK. I really appreciate all the vids you produce. Do you have on about the earth guard?
You cannot go wrong with JK.

@@OffGridGarageAustralia Yep - and for the weather forecast, I have a local digital barometer that can be used as well.
@@upnorthandpersonal Haha, that the best anyway and is never wrong😄
Thank you nice video, good luck, have a great week. M
Thank you Andy for testing that BMS because I send many complaints about BMS issues and they ignore that now I believe when thy see your videos will realise and upgrade the software issue's
I have very bad experience with 100smart BMS and now I back to JBAIDA BMS
Best regards from Philippines 🇵🇭🍺🍺
Thanks for sharing. That is not great of them to ignore your concerns. I think most of their BMS cannot even be updated with new software. Only the newer hardware version can.
JBD is certainly a good BMS.
I completely agree with your assessment Andy. I've been using the Daly BMS for a while now with the wifi and it works great. This new BMS seems to be a carbon copy of the bigger Dalys with a few minor differences. Daly has a new S series BMS which is supposed to be high current...can do up to 500A discharge and 250A charge. Would love to see your review on that one if you ever get your hands on one. One of the things I find Daly has missed in previous BMS generations and this new 100 series as well, is a high voltage and low voltage recovery setting similar to what the JK has. I think if Daly could incorporate that feature into their products, work out a few bugs and improve their documentation, they could increase their competitiveness.
I have several 250A Daly BMS here but had no support from them in terms of setting them up correctly. They Wifi implementation didn't work at the time and nobody seemed to know how to set it up. So they are still resting in their original boxes. They promised to be able to change the FW quickly as per customer needs, so I got excited and wanted to test their new BSM out. Daly for the win, you know... but the lack of support and not knowing when I asked questions... A huge company should be at the forefront. Well, JK clearly too the lead here!
Yup....i'm now in the process of migrating to the inverter style JK BMS after watching your reviews on them. Wish that the JK had the wifi option though but I guess I can pair them with Solar Assistant for remote viewing and monitoring.
@@hendersonsobers396 I tested the batmon-HA integration yesterday and it reads all data from the new inverter BMS via Bluetooth into Home Assistant. Great integration for monitoring down to cell level:
github.com/fl4p/batmon-ha
@@OffGridGarageAustraliaNice....will look into that as an option. Thanks.
🍺 congrats on 821,000 subscribers 😜🍺
Hahaha, the tape does not stick well and I gave up fixing it.
821000... just wait we will get there😂
great video! Are you sure that Frankenstein battery with different models of cells with different capacity leads to serious problems?
Thanks
I have to thank you for watching and commenting🙏
You should try Hibms. I use them support is good.
As for remote data, well I get around that by having my own hardware which is never down, doesn't fake data and keeps it local.
Does the same thing too.
At the mo I have this for just a few devices, but shall be expanding, in fact I'm making what I'm calling "the node" which is a "featured" display and interactive device that pulls data from inverters and battery and solar.
I've also developed a 'smart array' controller. This is on a back burner as the node Is taking more of time.
BMS systems do need to come some way and be standardised. As I have to code for each type, because they want to use different keys. Some are copied... China ey?
Keep up the good work.
Another OGG item added to cart but by the end of the video it's delete from cart 😂 Thanks for the review and as you said it's a shame! So close but yet so far!
Hahaha, yeah, you definitely don't want this BMS with such a half-backed software. I hope they can improve...
Just bought this. You need a USB cable to adjust the voltage and what warnings/alerts come on. They come on way too early giving you a red 'error' light even though everything is fine. Other that that I'm super happy with he product. All in one BMS with 1ah balancer and temperature meters. All for $50 for a 60amp model. Likely going to replace my old Daly with this.
Argh..😬 Thanks for admitting having bought one. The balancer does not work and stops working as many have written here.
Yes it turned off at 3.5 or level one high voltage. You need the USB cable to increase that. I put level 1 at 3.6 and level 2 3.65. Now it stays on.@@OffGridGarageAustralia
I bought 2 of these in January (4 months ago) to monitor, balance, charge and discharge my Tesla modules. I haven’t had any issues with it. Tested the over voltage, under voltage, high and low temp protect, and balancing. I like it so far.
@@Treeroy. That's great. The BMS will work with your Li-ion cells and keep them balanced. LiFePO4 is different though.
Also be aware, that balancing will turn off when warning level1 or protection level are met. The BMS also does not reset to 100% unless it hits OVP, which is a design flaw.
Heya, nice review of this BMS to bad it's not good enough
Hi Andy ! love your channel ! I’m planning to build my own DIY LFP battery soon … What do you think it’s the best choice ? Jk BMS ? or a Seplos BMS with a separate active balancer ?
thanks for your work ! 👍🏻
Definitely the JK-BMS. Either the BD or new PB series are great.
Good video. Let us see the upgrade BMS from 100balance BMS. It is coming soon. Thank you for your true feedback. we will grow up base on the market demand. Thanks
I’ve been using the 100Balance BMS for about 4 months. So far so good! Green flag from me that yall are watching videos like this and improving weaknesses
Thank you for your feedback . We have professional team to solve all these issues as andy mention . We have upgrade the version from Version 1.0 to be version 1.2. 1).Cable are too short ? The length of sampling cable are same as Daly's bms is 450mm. As we know, lengthening the cable means increased costs, not all customers require very long cables ,If the customer needs an extension, we can customize it specially or provide accessories as optional.(we have 800mm sampling cable) 2).Key switch cable ? many customers have switch head,and some customer switch head have some personalized design , so we only provide free key switch cable , meeting personalized customer needs 3).The USB quality of WIFI is bad ?Improper operation can cause USB damage. Our USB cannot be directly connected to high-voltage equipment without isolation, and can only be directly plugged into the computer port 4) Balance on problem ? Previously , stop balancing work after reaching level one high voltage alarm,but now the product has been upgraded and can always be balanced before reaching the overcharge voltage 5) SOC issues .The new version 1.2 has modified the hardware and the SOC will accurate. 6) Docking inverter protocol Yes, new version 1.2 can be docked with inverter protocol . We accept all of people to provide presious idea to improve our products, we will try our best to meet the market demand .

When does balance function start?
1). Do all cells need to be over balance start voltage?
2). Or when 1st cell reaches balance start voltage?
@@supashark72 Balance ON conditions : 1). Reach the set start voltage (Default 3V) 2. Reach the set start voltage difference (Defaults 10mv ). It means that the highest voltage of any cells minus the lowest voltage of any cells ， That's voltage difference. The above two conditions must be meet at the same time. if one of condition is not meet, balance will be closed.

A variable cell count BMS nice
Hello Andy,
Firstly, your video was well done, and I appreciate your insights. However, I'd like to address a few points from my perspective:
The 100BALANCE BMS is a low-voltage product, and its USB data cable is not intended for connecting to high-voltage devices. Therefore, when you connect the USB to high-voltage equipment, it can lead to mishaps. The user manual clearly states that the USB is meant for connecting to a PC for battery data viewing, not for linking to other devices. If you require additional testing functionalities, it's essential to communicate with the supplier for customization. This is not a flaw in the product but rather a matter of product positioning. The misunderstanding in the video arose due to a lack of communication with the supplier.
The target market for the 100BALANCE BMS series is pack factories. Their operational model involves customizing output lines according to projects and keeping suitable spare output lines. Therefore, the length of output lines can be customized by users themselves or by requesting the manufacturer to extend them, but this naturally comes with increased costs.
While charging and discharging currents can be made consistent, it would require increasing the gauge of the output lines.
100BALANCE BMS is a new brand, and compatibility with inverter interface protocols is currently in progress. New software is planned for release in April. Please continue to stay updated!
Version 1.1 has addressed the issue of whether the active equalization module can function during overvoltage protection. Even if overvoltage protection is activated, the BMS will continue to balance under appropriate conditions.
In conclusion, this brand has accumulated many years of expertise, with its technical development almost parallel to that of established brands. The only difference lies in the timing of market entry. Being a later entrant has allowed 100BALANCE BMS to avoid certain flaws present in other BMS systems and incorporate additional technologies. These include cloud platforms, Wi-Fi capabilities, direct parallel connection, built-in Bluetooth modules, and the ability to operate in both series and parallel configurations, thus better meeting the needs of customers. I believe this is a promising product that will continue to evolve in the future.
Andy connected the usb cable to his computers USB port, please, do tell me how a 5V USB port on a pc is high voltage?????
@@GapRecordingsNamibia "Friend, it's quite obvious that I'm referring to connecting to other devices, not to a computer! It's precisely because it successfully connects to the computer that we can read the data from the upper computer!
@@QINOU You wrote: "The user manual clearly states that the USB is meant for connecting to a PC for battery data viewing, not for linking to other devices."
So it can be connected to a PC but apparently only when running on battery??!!!
There is a design fault in the USB-Com device.
A USB Com interface should be able to connect to a Host regardless of the power delivery.
@@QINOU 1: You were the one that insinuated he connected it to "High voltage equipment"....?
Your words, not mine, you are referring to the user manual stating this.... WHY?
Why would you need to state this if you are not inferring that he connected it to a "high voltage source" causing the failure? So, again, please do feel free to give me a time stamp as too where he connected it to a high voltage source?
Also, nothing in Andy's off grid setup is "high voltage" all the USB ports on Victrons equipment is isolated.... So, unless you are saying it is not, I would select my words a bit more cautiously.
2: The ground fault that came up after he connected the USB dongle to his computers USB PORT, is indicative of a floating ground potential indicating a VERY poor design and a very big design flaw inside the Balance100 USB DONGLE where the USB dongle IS NOT ISOLATED!
The Balance100 is in need of some further development, nothing Andy said was intended as being an attack on the product, it was meant as being constructive criticism.
Andy has been doing this long enough that he is an independent reviewer. Andy was comparing the Balance100 to the JK BMS which is also actively balanced.
Furthermore..... The fact that you find the "need" to defend the company and try to fault Andy's testing shows where your allegiance lies........
Good day...
I connect the adapter to UART and a USB port of my computer, nothing else. There could be a problem with the adapter itself or the BMS.
Planning my 62Kwh build and 100 balance was really trying to sell me some of these. I had NO idea the "100A" model was actually a 50A BMS - based on this video the software is so illogical as if programmed by someone who isn't even in the battery industry, cannot take the risk with them now. Looks like I'll be messaging JKBMS and placing my order soon. Note* JKBMS is still developing their revised 51.2v kit which I would love to see you have a look at when its ready. Once again, thanks for the invaluable info Andy.
You will love JK. I have not had a single bad experience with their interface. Fast, simple, and reliable.
I wonder what model active balancer Tesla uses?
@@john_in_phoenixLikely in house. They build nearly everything themselves wherever possible.
@@evanmayer744Ditto- never an issue with JK.
What do you mean with "revised 51.2V kit"?
Those temperature sensor leads were also ridiculously short.
Oh, yeah, I forgot to mention that. They are so short, it's not funny any more... unusable.
Nice
Great product review. If JK could do wifi it would be perfect. Now its 4.5 frogs 🐸

Hey Andy,
top Video👍
Habe das BMS auch gekauft und bräuchte nicht lange um zu kapieren das es eine unfertige Baustelle ist...! Leider!!
Hardwaretechnisch echt gut verarbeitet aber das war's auch schon .. wie in deinem Video bereits zu sehen Balanciert das BMS nach Lust und Laune, spuckt ständig irgendwelche Fehler aus und der ON Off Switchanschluss ist auch ohne Funktion...
Ende vom Lied ist das ich das Teil zurück gegeben habe und dieses BMS ebenfalls nicht empfehlen kann...
Habe mittlerweile auch das JK Inverter BMS ( von dir angefixt 😅 )
Das ist schon was anderes 👍
Zum Thema JK wäre es echt Top wenn Du auf deinem Deutschen Kanal einpaar Deutschsprachige Videos machen würdest 😉👍
Beste Grüße aus dem Verregneten Deutschland

Thanks André. Yeah, the JK is definitely playing in a different league than this BMS. You did the right thing sending it back.
I don't have the time unfortunately to make solar and battery videos in German on my other channel, so that is probably not going to happen.
Again a great video Andy! Thanks!
Is there any update about the shelly showing negative power on the grid side? Followed your video after buying microinverter and shelly
This has been fixed after a few updates of the Shelly and also VRM. It just disappeared at some stage, but I'm not sure what fixed it. Grid now shows 0W.

DALY was always terrible at cel balancing; I wasn’t expecting a huge improvement
The active balancer works well here. They just need to turn it on correctly😄
@@OffGridGarageAustralia expect after turning it on, it will be working only when charging. Classic DALY.
Hi Andy, I'm sorry that this is off the subject but, will you be reviewing the EEL Battery battery box with the JK BMS? Thanks.
Yes, I have one incoming...
HMade an order for the above mentioned box. Have to comment here that their communications seem to be non existing. Asked couple questions before buying. No answers to this day. Made the order. It sat as it was for a month with no activity. Than it was marked as delivered. It's still in the active order tab not ok order tab so I don't think they consider it delivered themselves. May be a translation fuc..error. Those are everywhere and in some important places. Like Free shipping is mentioned all over the place. Even on the invoice...with charge of 50€ for free shipping. Also the tracking code they gave is still not existing for their shipping company.
Don't do too much business with Chinese companies directly but this one is the weirdest one thus far.
@@Kregorius So sorry that you're experiencing this.
I didn't even mention the payment process itself. The web page shows prices in €. It also shows price in € on the final checkout. And than it processed in dollars in PayPal. Adding another 20+ dollars for the conversation rate. By this point I was "I just need a box, gimme the box" and pressed on with the process. Could have saved some with some other repayment method. But read somewhere someone else having similar experience buying from them and they supposedly got they act together if dispute was started in PayPal.
👍👍👍
Cell Volt Hi Level 1 triggers @0.1V below the high voltage cell disconnect setting and stops balancing at this point. Balancing will remain off until the Level 1 alarm is reset. I've complained about this bug months ago. They refuse to change it, stating that the BMS cannot monitor Hi Level 2 disconnect voltage while simultaneously balancing and that enabling this option would result in high voltage overshooting the disconnect voltage and possible cell damage. They claim that JK is known for cell damage because of this feature being enabled, I call BS. It also will only balance while charging. If Hi L1 is triggered and charge is removed, it will never resume balancing even if the L1 alarm is reset. Another bug I've found that they refuse to correct (at least in the 4S-8S version) is that if any changes are made to the default high voltage disconnect limit voltage of 3.6V, the BMS will reset to default after some time, and display a default settings warning nag asking if you would like to make changes. As long as you leave the high voltage disconnect limit voltage at the default 3.6V, you can change the rest of the settings without triggering the default reset or nag message. And one more bug I've found, if you change the default password, none of the individual cell voltages will be displayed on the main display screen until the password is entered. If you leave the password at default or change it back to default, the individual cell voltages will remain. So much potential, it's unfortunate that Daly engineers have their blinders on...
Oh, wow, thanks a lot for sharing. That is indeed quite concerning and not great. I will contact them again after Easter and see what I can do in terms of software improvements. The voltage will not overshoot and damage the cells. That can never happen while balancing. This software seems to be much worse than I have tested it. Do you use the Daly or the 100Balance BMS?
This was on the 4S-8S 100A 100 Balance BMS.
BTW, Andy, this BMS also phones home WITHOUT registering an account or connecting to WiFi. They had a server outage and the app would display errors every time it was unsuccessful at contacting the server, like every three seconds, which made the app unusable until they fixed the server issue. Makes me wonder what data they are collecting...
I also contacted them about this. I bought the USB cable and raised the vol 1 high voltage to 3.6. This has helped tremendously. Unfortunately if I get a runner, it'll hit 3.6v and not turn balance back on until 3.45v You cannot change that setting on the computer. Mine balances while charging and discharging. So I think you're wrong that it only balances while charging.
@@shawnd567 They have now changed the software. I have a new device here and it is supposed to work correctly now. If not, I can upgrade this BMS with new FW now.
Hi Andy.
Greetings from sunny London 😅.
Great video as ussual.
I watched all your videos. Just purchased 280Ah Envision grade B cells and need to get some good BMS to go with my Victron setup.
Little bit confused what to choose as BMS. What would be your ultimet choice to save me going through all opinions on-line.
Trust you the most.
Keep up good work.
Hello to sunny London... wait, what???😂
Get the JK-Inverter BMS with 200A for your battery. The PB series has the built-in 2A active balancer and will take care of your battery once build.
off-grid-garage.com/battery-management-systems-bms/
@@OffGridGarageAustralia Thanks Andy. Ordered already and on the way.
Ordered that JK case XR-07 too. Hopefully quality is going to be nice.
Already thinking about swapping battery isolator built into it with dc braker.
Hopefully Envision grade B cells will not disappoint.
@@marekc8654 That's an interesting case for sure... Yeah, MCB would be good to have as a main switch for such a battery.
I had high hopes for this as it will work on a 15S pack that I am using, however I guess I will just stick to Daly. It there any way to make the the JK unit work on a 15S pack?
The bigger screen is standard with daly
I used one its nice so you don't have to to connect with bluetooth but it could be better you can't do everything as on the app
The poolcleaner from Andy two....🐸🐸🐸🐸🐸🐸🐸
He will be back soon...
The NEEY 15amp active balancer is still the best active balancer out there.
It is the biggest out there, for sure. But yeah, it's very powerful and robust. But also expensive.
Hi Andy, in Sachen UART Adapter habe ich das gleiche Problem. Mein Akku mit Daly BMS am Raspi, verbunden mit eben diesem UART/USB Adapter, lief seit Mai 23 bis Winter unauffällig (und hat den MP2 gesteuert). Über Winter Akku in Revision. Verändert habe ich lediglich die Spannungsversorgung des Raspi von Original-Ladestecker auf einen DC/DC Konverter 60V/5V 3A und ein USB Verlängerungskabel (1m) zwischen Daly und Raspi, da Anordnung geändert. Nachdem das ganze Ende Februar wieder online ging, hatte ich nach ca. 2-3 Tagen einen "LOW Battery & BMS Lost" Alarm. BMS war auch nicht mehr erreichbar, auch nicht durch Verbindung Laptop/Daly mittel besagtem Kabel. Vermutung das Ding is hin. > Neuen Original Daly Uart/USB Adapter gekauft, angeschlossen alles wieder online und wie gewohnt. Noch in der gleichen Nacht wieder o.g. Alarm > Adapter wieder hin... Hab jetzt mal genauer geschaut, sind auch beide leicht gewölbt.. Keine Ahnung warum das so ist werd nochmal nen NoName UART/USB testen aber Entscheidung is gefallen zu > JK Inverter BMS bestellt Daly fliegt raus... DANKE für deine tolle Arbeit, sie ist extrem lehrreich und unterhaltsam ;-) Happy Eastern...😉
Thanks a lot for sharing. They were trying to blame my setup but I knew it was their adapter which was not isolated and some of the load current went through their adapter back to ground. This melted the internal controller as shown in the video. A different brand of adapter may help but the problem could also be on the BMS site.
ciao Andy , io uso 3 daly da 300 AH ma il bilanciamento parte da 3,1 v e al 100% di carica ho una differenza celle da 0,004 mv.
Im still confused, is it okay if the active balancer is continuously on or not? Because i have seen a lot of set ups that has BMS connected in parallel with active balancers.
Or it only needs to turn on at specific cell voltage like 3.5v.
And what BMS brand has that function? That the active balancer will only turn on at a preset voltage (maybe 3.5v)
Thanks Andy for your time checking on my comment.
The balancer on every BMS only works above a certain voltage which can be adjusted in the settings. Usually, 3.45V is a good start point for LiFePO4 cells.
Pretty much every smart BMS with Bluetooth access has such a setting, regardless, if the BMS has an active or passive balancer.
BTW- I just installed the 100Balance 4S 1A Smart Balance active balancer on a small 264Wh LiFeP04 pack in my car and it drained it from 3.52v/cell to 3.38v/cell in just 6hrs on default settings. Just goes to show, nice looking packaging and colors doesn't mean much :) Thanks for the throughout video !
OK, but 3.52V is very high voltage for a LiFePO4 battery and way out of the flat part of the charge curve. It will take very little to lower this voltage. Even without anything connected to the battery, voltage will come down naturally over 6h.
Turn down balance open voltage to 3.0v, works for me on 6 separate banks.
Releasing the magic smoke!
Wires are just pipes for smoke, when something goes wrong the pipe gets broken and the smoke is released.
I never thought about this😄
I have an idle drain of about 50-60W with the Daly smart BMS which technically should be the same as this 100balance bms. their support is crap, so i have not got an answer for several months now.
the rs485 seems to somewhat work with my Deye inverter but i can't get CAN communication to work. i believe improper communication is also the reason for the idle drain i am seeing above.
I’m actually planning to buy three of 15s 48V 250A for replacing the damage BMS on my Tosen 48V200ah power wall both bms gone dark at the same time. Any suggestion would be highly appreciated.
The baud rate is 500 for the can port. But to behonest i couldnt get it working. Hope you have have better luck. Yes this is daly.
No chance. Apparently, this feature will be working after an update...
@@OffGridGarageAustralia u mean bms update or app update. But I have seen there technician using CAN to connect. But it could be a different CAN Adopter as in the video his Adopter was covered so couldn't see what it was.
I have one of these but just the balancer and it works very well.
Their balancer is just a 5A capacitive balancer without any 'smartness' or settings you can change and it runs forever, right?
1A smart active balancer ?
So They don't balance if they are not being charged?
Yes, Daly and some other BMS have only charge balancers. If they don't show any current flowing, they stop balancing. 🤷♂️
Mine balances when not charging. So that's false.
So you'll be asking JK to add Tail Current to the 100%-reset function? That would be EXCELLENT!
Yes, not sure if they can fit another parameter in.
I hope the manufacturer addresses the issues with this product, most importantly the Active Balancing behavior, as I believe it to be unique solution for those in need of a well protected (housed) BMS with Active Balancing that can be used in both 4S and 8S configurations.
Unless I am mistaken, the enclosed Jk BMS with AB is only available in a minimum 8S version.
I live in the tropics and build solar electric boats, and unfortunately our environment can be quite hard on electronics due to the salt air, condensation, electrolysis of dissimilar metals, geckos, etc.., so a waterproof/resistant BMS in a sealed enclosure would be most ideal.
They won't. I had a lengthy discussion with them, and they are happy with their current design and won't change it.
The problem with sealed BMS or electronics is heat dissipation. You probably have to build your own enclosure and ensure sufficient cooling.
I want one of these electric boats, Will! They look amazing!
Bummer to hear that. Thanks for the heads up. I will have to go a different route then.
No doubt heat is the enemy, but at least in those situations components can often be replaced.
Corrosion damage from salty condensation by comparison, is a total killer.
Might experiment with thermally conductive silicone polymer encapsulate next build. I suspect most standard BMS boards leave the factory with only a light coating of oil.
Thanks for the kind words on the boats.
You should build one for yourself!
Old boats in need of repurposing are plentiful, and if you like to spend time relaxing on the water, doing so using the sun while cruising along to the sound of trickling water is such a great way to experience it.
Of course if you prefer to go fast, you’ll need some big batteries and a lot of solar!
I just thought for myself why i should allow a webinterface change safety critical parameters in my BMS? I never would accept the risk.
You mean the Wifi remote access?
@@OffGridGarageAustralia yes. As far as i understood, you can also change battery safety parameters. Upper threshold voltage, etc. I see this as a risk in several aspects.
Hello, what model of your safety glasses?
They are just cheap ones like these here: s.click.aliexpress.com/e/_DmZV9op
Hello. Witch active balancer is the best, of non-smart ones? Have tested the 100 balancer, not working. Have now bought Daly but it seems to be the same type. Need a simple cheap one for 6S. Many thanks for the help. Regards Lennart
Do you have the balancing option selected “on” on the 100Balance BMS? There’s also settings for when it begins balancing
If i buy a separate 5a active balancer, then im good?
One of these days Tesla, Rivian, VW, and BYD must notice they have overlooked active balancers.
I don't think they need active balancers. Tesla has an open patent on their balancing design. Very interesting and fascinating to read.
I don't understand the complaint about the balance start voltage. Surely setting the start balance voltage much lower is desirable, so that all the cells get to the cut off together. The default setting was 3.0 in the PC app, which makes sense to me.
For LiFePO4 profile, balancing cannot occur under 3.45V. The cells need to come out of the flat part of the charge curve first. 3V will not work at all...
Greatings Andy, any idea why my JK BMS shows correct 13.3V while on the battery terminals there is 13.08V? When i apply 0.023A load the voltage drops to 12.8V? Bms still shows 13.3V...
Maybe needs some calibration in the settings menu...
@@OffGridGarageAustralia Thank You for the reply. The best part is that when i apply some bigger load, the voltage drops but a second later it jumps back to (13.3V):) as if the BMS had some kind of a buffer.
@@dominIKhs very weird indeed. Have you checked all cables and connections, balance cables...
What are the cell voltages show when you put load on the battery?
"His Data" Andy? Hilarious...lol
🤣
When you set it 3.65V and it displays 3.7V, is it setting the voltage to 3.65V but rounding the display to 3.7V? Or, worse, is it taking your input of 3.65V, rounding it to 3.7V as the setting (too high of a voltage for LFP) and then displaying the actual setting of 3.7V. That would be very bad.
I think it is just the display. It shows one digit after decimal in remote screen but 2 digits when connected via Bluetooth 🤷♂️
Standards Australia should be very interested in this product because it actually has the capacity to allow a battery runaway.
I suspect the majority of battery fires from electric scooters to electric cars are caused by a faulty or badly designed BMS, NOT the battery itself!
if this was a Mains power product it would be immediately recalled, and yet with the possibility of it causing a major fire and possibly death there is little oversight by govt on the these products or their suppliers.
There is light coming in from the windows. That counts as sunny around here.
Hahaha, great😄

Do you know about the windy app. It has W/m2 uv index wetter radar and allot more.
Yes, I know the app.
What kind of active balancer it is ? Is it capable of charging/discharging individual cells and redirect the charge to the output ?
What do you mean by output? It discharges the cell with high voltage and transfers the energy to the cell with the lowest voltage in the pack. I still have to open the BMS and see if they use super caps to store the energy. That's how JK does it (until their new BS comes out).
@@OffGridGarageAustralia Ideally, the active balancer should include isolated dc-dc converter, which can be connected to the output of the battery in case of discharging, that is, partially redirect the charge of the cell when you are using the battery, as it results in minimal loss.
Let's say, your battery output is 12V, the ideal balancer should discharge 1 cell with the highest voltage to that 12V using DC-DC converter (galvanically isolated). Plus, a switching circuit to switch to any cell with the highest voltage.
That is, it should support unequal discharge of the cells. As well as charging via the same or separate converter.
@@OffGridGarageAustraliaIn best case, you should be able to charge and discharge a battery made of different cells (even different chemistry) with similar capacity with fine regulation of charge and discharge current for each cell individually without much energy loss except for an additional stage of DC-DC conversion (roughly 10% of energy loss for the value of difference in capacity).
Manufacturer date is likely for inputing the battery Manufacturer date?
Yeah, I know that, but why can we change this through the screen? It is so not important...
Hello i have Question i have 25 s BMS dont understand Programm the Board have 3 First IS Standard 16 second 7 what IS the rigth one for 24 s
💙👊😎
Thank you.
Does it work as same as daly BMS, and works fine even without wireless connection? I have the daly Bluetooth Adapter connected only for set the settings, because of Electic Sensitivy. Answer at the end of the video: Build in Bluetooth funcionalitay.- not my BMS.
My word! I'd wish, the new JK-PB had switchable bluetooth. It's definitely doable but overlooked by the manufacturers.
I'll see if I can get JK to have a BT switch in one of the next FW updates.
Error Msg at 19:46: " Failed to open device. Please check whether device type and device index number is correct"
Ah, thanks! I checked all combinations. As I said turns out, the feature does not work yet with this BMS. Needs a FW update.
So I bought the 100 Balance BMS and had similar issues... would not charge up to total of 14.2v, only 13.56v... didn't balance AT ALL... so I'm out with these, very disappointing. THANKS for the warning! I should have really looked at it, thought they'd have it all "worked out" but by 5/10/2024 they have not.
Still sounds like this BMS would be a drop in improvement for current Daly BMS the balance leads should just connect and you are working?
It seems they are using different connectors for both, the communication ports and the balance cables. Because, why not🤷♂️
@@OffGridGarageAustralia Thanks for checking that is insane lol.
USB ports are earth grounded. Is that the issue with getting hot?
minute 18: I had a plug on my Daly BMS that was just as hot and then defective ;-)
Hmmm, there is something going on with their adapters or BMS...
Daly, when no charge current, no balancing. Overvoltage cell charge shutdown, no charging, no charge current therefore no balancing.
Looks like it took it one step further shutting down balancing at cell overvoltage pre-warning level.
The software is terrible! I cannot believe they are delivering device like this. Obviously untested.
Another BMS to the back of the shelf?, I was hoping for MQTT logging, I am looking at another device coming in the mail from dalybmswifi that logs data a Daly and a JK BMS coming out of Italy
There are a few solutions I have tested in HA now. Batmon-HA looks really good and works with a lot of BMS through Bluetooth. It uses MQTT for all the data transfer. works a treat.
@@OffGridGarageAustralia I have been using Batmon-HA on one of my battery banks for about 6 months, but it does crash every week or so' the most stable monitoring hardware I have is Stuart's DIY-BMS, very rock solid along with a Emonpi to capture the MQTT data, that I have had for 6 years, faultless bar a memory card failures
👍🏽🍻
🍻
JK bms has an esphome/home assistant capability...not connected to overseas servers :)
I heard about that...😉
I'm not sure if i should be offended by the short balance cable comment, .... i mean its all in how you balance it, not how long your cable, i mean cables are ;-)
FYI your at 83k now time for the numbers to be adjusted (UP)
1+2 I have on the wall😉
I just brought edel 7 ldv
been charging of my off grid container
at night no worries but during the day keep getting ungrounded alert
on charger
i remember u had similar problem with ur tesla.
i have circuit breakers with good earth stake on system
how did u get around it
i have 6.2kw pow mr hybrid inverter
20 kw usable battery
I have disconnected positive to solar as well still no luck
I had issues when charging the vehicle from an off-grid inverter. I had to make one of the 2 'floating' actives the neutral and connect it to ground. Like a MEN link in a switchboard. Then the vehicle didn't complain any more.
Please help me choose. This one or daly bms? Ill add a separate active balancer.
Daly? never
That is just a daly in a new bleu jacket
I have these screens as wel
The screens are actually good. The colour choice is a matter of taste😄
It is like the HiBMS that uses daly wifi and bluetooth.
I'm getting cold down here 8 degrees in the mornings. Next month is almost here. Could hear the Mozzy in the background, Andy.
Still got well over 15° in the morning here...
Yeah, the mozzies like the hot camera when recording.
@OffGridGarageAustralia Like the flys down here. April is coming, and I can't wait for the new system. 😉
You had the cominication set to can in the bms maybe thats doesnt work with the usb
The USB uses UART. CAN communication is for the inverter connection.
can you edit the Cycles?
Haven't tried it...🤷♂️
Hello
can you briefly explain the problem in bms 100balance?
because I don't really understand your tutorial in English,
My understanding of English is weak
Thank You
Half charging current is just the common setting for lithium cells on non configurable BMS
Apparently Daly and 100Balance does it. All other BMS have full charge power.
@@OffGridGarageAustraliaThis is related to a cell's charge current, which is always lower than its discharge current.
If a battery has a max discharge current of 100A, it's legitimate to think that 50A charge is good with cells usually at 1/2 C or 1C max (with life cycle sacrifice) and a discharge current of 2C or a little more. It's rules of thumb
I believe that in the case of Daly, the manual mentions the default setting, but that 100A is perfectly available by configuring it,
There's technically no reason why the MOSFETs and the rest of the power circuit shouldn't handle as much current in both directions.
