The 100 Balance BMS with 1A Active Balancer and Wifi. A true JK Competitor?

[@stefanandr]

Great video, which I first saw after I purchaed it. The good news is that I just installed the 100A version from the 100 balance BMS, and got the latest firmware update from July and as far as I can tell the problems described in the video around the balancing seems to work now. So I am very happy with it. Only issue I can find is that the font size handling in the app on the iPhone could be better.

That's great news. I was just about canceling my purchase in Aliexpress because of the balancing issue showed in the video. Thanks for sharing.

[@ErhanGazi]

That's great news. Can you pls tell me how to update that? A video or user manuel?

[@BobHannent]

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.

[@OffGridGarageAustralia]

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.

[@BobHannent]

@@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. KZbin 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.)

[@OffGridGarageAustralia]

@@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🙏

[@typxxilps]

@@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.

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

[@OffGridGarageAustralia]

I had only one frog at the beginning, but the Wifi and easy firmware updates seem to be good features, so... 🐸🐸

[@ElieHarfouche]

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!

[@OffGridGarageAustralia]

Yeah, really a bit disappointed with this BMS. I hope they can improve with a firmware update soon.

[@hendersonsobers396]

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.

[@OffGridGarageAustralia]

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!

[@hendersonsobers396]

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.

[@OffGridGarageAustralia]

​@@OffGridGarageAustraliaNice....will look into that as an option. Thanks.

[@trevortrevortsr2]

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.

[@MegaCyrik]

Hmm interesting.. now to add tiny heatsinks and thermal paste on them :)

[@michaelburke1023]

Nice thanks for sharing

[@FutureSystem738]

What passive balancer was that?

[@OffGridGarageAustralia]

Passive balancer...🤔

[@jbuszkie]

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.

[@maritzm]

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.

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

[@Treeroy.]

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.

[@OffGridGarageAustralia]

@@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.

[@EF-Electrics]

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).

[@OffGridGarageAustralia]

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?😄

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.

[@SwichMad]

Its good practice to use a laptop on battery power o ly when connecting to inverters, BMS's, protection relays or any other equipment that can crate a path to ground. We had it with victron where it blew the usb port on the laptop becuase it was powered by the inverter itself. We also had a 1.2MW central inverter can bus fried by connecting to the diagnostic port while the laptop was plugged in. Since then, I carry a small inverter in the van to have completely separate 230V suplly for the laptop.

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.

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 .

Ok, update here. Been running my 60A 100 Balance BMS now for a couple weeks, with apparently the latest firmware. It active balances while both discharging and charging when the cells are above 3.7V (my setting). For my first BMS, it has been running very well. I have the high voltage protect setting at 4.1V, I believe. Above 4.05V for all the cells (52.65V), it complains about "Cell voltage level high 1" I have my Victron 150/45 MPPT Bulk/Absorb at 52.65V and Float at 52V (54.6V is fully charged for a 13S Li-Ion battery), so according to the BMS, that's like at a 95% SOC.

They did not want me to do a follow up video about the 'upgraded version' of their BMS. It is still not working correctly and shows the same flaws as the version before.

DANKE für deine tolle Arbeit, sie ist extrem lehrreich und unterhaltsam ;-) Happy Eastern...😉

[@OffGridGarageAustralia]

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.

[@alpinerep]

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...

[@OffGridGarageAustralia]

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?

[@alpinerep]

This was on the 4S-8S 100A 100 Balance BMS.

[@alpinerep]

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...

[@shawnd567]

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.

[@LeonardoSofia-IU2-QEB]

Ciao Andy, I noticed something in your settings, which, at this point, seems to be the default, because it was the same in my Daly BMS and caused me some troubles. Level 1 is alarm and Level 2 is protection. Level 1 should be always more conservative than Level 2, as Daly support confirmed me. Your over current discharge level 1 is 100A and level 2 is 80A. I have a Voltronic inverter connected via RS485 to the WNT interface which is connected to the Daly BMS. It was happening that during very sunny days the BMS was stopping the charge mosfets for several hours and the battery was never fully charged. Then I understood why. The communication protocol set into the inverter is LIB and this set automatically the max charging current reading it from the BMS. Can you guess which of the two values was taking? Yes, .... Level 1 And for this reason the protection was always triggered 😂. Other bad thing is that the mobile app doesn't allow you to set both levels, but just Level 2. In my opinion (but I don't have experience with other brands) their hardware seems good, but they have to improve documentation and software which is too complicated and has strange behaviours. Bye.

[@OffGridGarageAustralia]

YEs, good observation. I didn't pay much attention to these details but your are right Level 1 < Level 2. It should actually complain and don't allow me to do it the other way around.

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.

[@OffGridGarageAustralia]

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!

[@kauaislash5]

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!

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.

A USB Com interface should be able to connect to a Host regardless of the power delivery.

[@GapRecordingsNamibia]

@@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.

FYI, newer 100balance firmwares are available (ask the company to get them) that finally fix the "balancing only when charging" issue, I have a brand new 17S-150A at home with this newer firmware, it works fine on that aspect (I sent you an email about this)

[@SheilaMaeAmihan-qh8kd]

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.

[@OffGridGarageAustralia]

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.

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.

[@OffGridGarageAustralia]

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...

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.
