I love companies that iterate quickly and actually listen to customer requests. This is not a given and is actually quite rare. They deserve tons of credit! 👏🏻
Unless, you are one of the poor folks that bought into 1, 2, or 3 gen...I am sure they offer a free upgrade program...I am sure.
Hi from a fellow Aussie. I've designed a number of BMSs and passive balancers and really liked the look of this. I've just connected it up and it is doing everything I expect. Thanks for suggesting the improvements, without which I would not have bought it. I told the store that I only bought it because of your work, your videos and your suggestions plus the changes they made. Keep up the good work, regds Dave
I bought the new 15 amp Smart balancer. I cannot find an app for the Android phone. Do you know where I could find it? Thank you!
Great review and it looks like a solid product now. The folks at Neey have earned respect for working with end users such as yourself, taking your criticism to heart and making changes to improve their product. I'm impressed!
You have done a great job in guiding Hankzor. The big change in the 4th gen is they no longer use the average pack voltage but first past the post for sampling which allows balancing to come on earlier.
You are now in a position to do a head to head before we claim the Neey is best bang for buck. Isolate your 16S JKBMS pack. Fully charge to 56V and balance to 10mV. Discharge 1 cell 50-100Ahr. Then maintain overall pack voltage at 55V and see how long it takes active balancer to get delta V to 10mV. Do for both JKBMS active balancer and Neey to see if 4A is really better than 2A.
Then you can get a JK 2A standalone active balancer and do the same comparison and you will have a definitive winner to announce. You may even be able to debunk the myth that a active balancer needs to be turned off below below 3.4V and you can use just delta V to switch on/off for LFP systems ( as long as you don't charge your Tesla!)
I put one on my 23kw 15p14s 30ah 3.7v battery pack and this thing worked great! Went from over 100mv difference to 1mv overnight. For NCM this thing rocks!
I can't help but think of "The Knights Who Say Ni!" when you say neey.
I don't think you'll see this post.
But I was told (by NEEY) that a 12V system (even a 8S) would need a DC power supply. The NEEY will not work on 12V and 24V systems without a power supply.
Yes your right. As I've just found out. I've sent it back. I've ordered the 10a version with a separate power supply.
Its 12.31am n just got the notification so addicted for ur videos. Wanted to comment before watching it. Lol.
One thing to keep in mind. It’s not really “4 amps”, eg you can’t push 4ah in an hour. It’s more like 1ah due to the procedure used. (Discharge/charge is done separately and the periodical voltage measurement “cost time”)
Andy, just an fyi, I ordered a balancer just now and wanted you to know that I also left a message telling them that your review and posting a link to their store was why I bought from them. Thanks for the review!
Thanks for your support, Phil. That is great!
They should have branded this iteration the "Yeeeees!"
Great job Andy, you are my candy.
BTW I really love the battery setup with the flex busbars and all + on one side.
It looks so neat. Easy to read. Easy to lineup all the balance cables.
I love it . Clarity.
I bought two for a pair of parallel 48V 16.5KWh battery banks based on this video…
They work perfectly!!
😳 not only are this guys videos filled with great nerd info, hes also a nice funny entertainer….😃
great regards to you Andy in the AUS
Thanks a lot for your feedback, Hans. Much appreciated.
Thanks for the video, Andy. Greetings from cold and wet South Australia. Nice to see a company was listening to their reviewers and customers. May the sun shine for you.
After watching your video review of the new Daly BMS with smart Active Balancer, I started regretting having bought that same BMS under the HiBMS name. But you kept comparing it's smart active balancer to the Neey 4th Gen, so I clicked on your Aliexpress link you provided and was surprised that it sold for than $12. Now, as you suggested I can use it together with the Daly active BMS or use it to assist my ANT BMS. Thanks so much for your precious videos! I always turn to them when I'm revising my LiFePo4 parameter settings.
It doesn’t sell for $11.xx there are three choices there, a cable or adapter are that price, you’ll be sad to see the price of the actual balancer…. (I thought the same thing until I thought it was too good to be true and looked more closely) (I’m in the USA)
@@benji888578 Yes I'm in the US too and right after listening to Andy promoting the Neey balancer, my mind went numb and I fell for the tricky add. Yet I'm usually very cautious, but I was dumb or blind that day. Of course, they rushed to ship the cable! I got an update through my email while trying to cancel the order. Hopefully they will, but if they don't, I'm actually lucky that it was only $12 and will learn from this lesson. Cheers!
Merci pour toutes ces explications et cette démonstration du NEEY Smart Active Battery Balancer 3.0 "Off Grid Garage".
A Perfect Requirement analysis and a perfect acceptance test. Thanks for sharing.
Thank you for your kind feedback.
Thanks for this update and testing Andy and nice to see that these manufacturers are responding to the feedback. Im not convinced at this stage that this new balancer will do a better job than my 48v JK BMS, or that I would require it. There is a 90 second turnaround on each cell being balanced, compared to the JK constantly juggling between cells. Im not sure how this new model is doing its charge/discharge cycle, but it would appear that it doesn’t series the caps output like we believe the JK does & I think this is what may make the JK possibly a more efficient Balancing method. Interesting to see how this one goes, seems to be a vast improvement from previous versions. Cheers All
Thank you Andy. How do I recognize that it is the 4th generation and not the previous ones. Sellers say there is no label that proves the 4th generation. Andrea
Devo ordinarlo qualcuno sa dirmi come riconoscere la 4 generazione?
It’s all I’ve been using lately. Thanks to you Andy. Set and forget. SleepVol @ 3.43 vpc and EqualizationVol 3.44 vpc.
While it’s great that they have really listened to your feedback and quickly made improvements, it’s quite a bit more expensive than the regular Heltec, especially in a 4s configuration as seems really inefficient given the capacitor charge discharge cycle. It would be really interesting to see a head to head without any extra loads comparing how long it takes for each one to really balance a pack. There are small devices to control the Heltec and it may be possible to turn it on and off using a relay.
Yes it is cheaper but this one actually works. The heltec is a piece of junk. I have them both.
@@penandpike Limiting the discussion to 4s battery packs, there is approximately a $110 cost difference for 4s models on Amazon.
How much of a functional difference is there that would justify spending $135 vs $25 to balance a 4s pack?
Have you had actual problems with the Heltec style balancers or are you referring to performance/result differences that you think justify spending more for the Neey Smart balancer?
@@inmyimage1081 I have a 16S 8P battery bank and at the beginning I tried these heltec balancers. they were never able to balance my bank, and they were actually drawing (wasting) energy. I will not use them even if I can get them for free. Everything changed when I started using the Neeey balancers. You can check my profile and look some of the videos I have about my off grid solar system if you want.
@@penandpike Thanks for the extra info
Bravo, vous êtes passionnez, vidéos bien détaillées et commentaire clair poursuivez votre bon travail!
Chris
Thanks a lot for your generous support!
Great video Andy. After watching this I've made a decision to buy the Neely!
Thanks Andy, really great test, love your work, and great that they’ve changed and improved the BMS so much.
(I’m still waiting to hear back about my faulty 4S-8S JK BMS. I guess I have to be patient …..)
Cheers from central Qld, enjoying being away from the rat race.
Please tell Hankzor that there is high demand for a 350-400A 4-8s JK BMS in the RV world!
I bought a super cheapo active balancer which activates at 100mv diff, and stops at 20mv diff. As it happens my cells at 3.5v = 60/70mv.but at 3v = 0mv. So even with lakitto cheapy cells it all works out fantastic. They wouldn't Bottom balance but if the top gets too far, it's nice to know it'd active balance, and stop again at float.
I was thinking the same. If the balancer is only active when the V delta is above a threshold why do you need anything else?
people are gonna think im smart because of you. researching my next batterys parts . thank you
Hmm... watching the video again. It claims to be about the 4th generation. But it looks like it is about the 3rd. Watch the black white part where Andy talks about the iterations of the balancer. Because today I installed a 4th generation. You can now change the device name. Convinient, because I use more of them in a Seplos Battery Stack.
Volker, any chance I can ask you to check the firmware version in the app ? I am supposed to have version 4, but says firmware 2.8.0. Thanks in advance!
Great job.. love everything you do with solar ...I learn alot from you..
The good question should be: would you use it with the JKBMS?
Good review Andy, but I have to laugh, remember the early days when you said you didn't need a BMS? and then why would you bother with a balancer! Hmmmm learning at our expense?
Anyway love all the reviews. Oh and by the way flattened copper (most conductive material) pipe makes perfect Bus bars for little cost.
how can I check which "generation" of HW I have without going through/doing a testing? Is there a HW version somwhere I can check?
It'll be grate, if Neey manufacture upgrade the bluetooth app for we can get SOC of battery or single cell, differens in mOms to control quality of busburs conection and cells resistance.
Really good now. It looks like it balances two cells at a time the high one and the low one.
How do i know I got the 4th gen vs the 3rd or 2nd?.. it looks the same..
Well I just bought the Neee from AliExpress. I hope they send me the latest ver. 4th.gen. Thank you Andy for your efforts to making this device better. 👍
Hallo Andy, vielen Dank für Deine Videos!
Ich habe mir den 4.Gen Neeeey 😅 gekauft und er funktioniert prima mit meinem 16S 280Ah und Daly 200A BMS.
In der IOS App gibt es allerdings nen kleinen bug, man kann nicht mehr als 200Ah einstellen.
Eigentlich hätte der Neeeey es verdient in Jaaaaaa umbenannt zu werden. 😉
Das Problem habe ich auch. Habe ihn erstmal auf die aktuell verfügbare Kapazität von 179Ah gestellt und beobachte das mal.
With that tiny balancer, you can switch them off manually. There are a pair of contacts on the edge of the board, marked as “ON” as I recall. As delivered, the contacts are joined by a solder bridge, but if you remove that solder bridge, then you can attach a simple activation switch in its place. Then you have a choice here. If you have a battery bank with at least a pair of batteries of “ample capacity”, on something like a boat with just solar power available, then the batteries will sit comfortably at less than, say, 90% SOC where no balancing will take place because of the very flat voltage curve around there. So then balancing becomes more of periodic maintenance operation where you might switch the loads away from one battery and the charging away from the others. Then allow that one battery to charge higher where balancing can occur and switch the active balancer on manually. Then repeat on another battery. Is this feasible?
Hi Andy, keep up the good work. I see that your tools just hang above the naked terminals of your battery. Hope it won't fall when you aren't there... Then it's "off grid burned garage".
In the beginning, I shorted 4S cells in my dining room one grid failure night....remember the black terminal in China is positive. 😵💫 Molten aluminum blasted all over the place. Terminal still barely useable.
Very informative review and supportig implementation for the manufacturer and the consumers. But little suspicious on too much Neeeying for the Hankzor.😄
Please help!! Is this product from the link provided is suitable for 8s 24 LiFePO4 battery
Heya, oke that is nice that they make the balancer after your specifications. nice very nice welll done
Every time this appears Monty Python and the Holy Grail pops in my head.
Where can we find a shrubbery?
@@bildad1234 From a Shrubba, please use them, they are under deep economic stress at this time in history.
@Off-Grid Garage: Hi Andi, I have good experience with the following settings: StartVol=0.005V, SleepVol=3.42V, EquaizationVol=3.44V. I use LFP Batteries and hav set me Victron MPPTs to bulk loading until 16x 3.45V = 55.2V and absorbtion loading 55.1V. So the Neey kicks hwen teh highest cell goes over 3.44V does the balancing at the switching point from bulk to absorbtion and shuts off when cell voltage goes under 3.42V, what happens when there comes no power from the MPPTs or when the load is higher than the sun input.
Used to watch Will Prowse, but he got high fluten with rack batterys. I added 2, 4 s 280 lipo to my camper. And I find this channel very usfull for the home gamer.
For the average person rack batteries are much safer. There are too many ways to blow hot molten metal all over the room, burn your power shed or house down with DIY packs. They use the same junk cells.
Congratulations, the videos are TOP TOP . I wanted to ask you should put 2 Active NEEY 4A balancers . 1 active from 3.2 to 3.3. and the 2 from 3.4 to 3.45v. What do you think? Thank you.
Danke Andi. Wir haben eine 16kWh Batterie mit einem Pace BMS. Die Batterie wird mit einem Victron Laderegler geladen. Keine BMS Kommunikation. In den letzten 10% gingen die Spannung ab 3.4V ganz schön auseinander und das BMS hat abgeschaltet, weil eine Zelle über 3,65V gegangen ist.
Ich habe die Ladeendspannung (float und absorption) runter genommen. Der Balancer im Pace BMS wirds schon richten? richtig?
Balancing ging nur sehr spät an und auch nur, wenn geladen wird. D.h. es gab Balacing pro Tag für 30min mit ein paar mA über ein paar kleine SMD Widerstände.
Totaler Käse.
Am Wochenende habe ich endlich den NEEEEEEY eingebaut.
Startspannung habe ich auf 3,475V und Ende auf 3,400V gestellt.
Bei 3,475V mit der höchsten Zelle war die Differenz bei 70mV. In knapp 5h hat der scheinbar das Gröbste ausgeglichen. Jetzt war die Durchschnittsspannung bei 3,465V und eine max Diff < 8mV.
Vorher habe ich beim Laden gegen 100% der Batterie den Strom vom Laderegler begrenzt, wenn die Diff-Spannung > 280mV war. Mal schauen, ob das noch notwendig ist.
Die Temperatur vom Balancer hat mir ein bisschen Sorgen gemacht. Die ist bis auf 65°C hoch. Der NEEEEEY sollte aber bei Übertemperatur abschalten. Zumindest gibt es einen Fehlertext dafür im Status.
Der Einbau war recht einfach. Die Leitungen habe ich alle gleich lang gelassen. An die Batterien habe ich immer den anderen Pol benutzt um die Leitung neben der vom BMS anzuschließen. Zuerst wollte ich das mit der Adapter Platine machen. Als ich bei Jörg im Blog gelesen hab, dass der Probleme mit Spikes auf dem BMS durch das Balancing hat, war ich froh, direkt an die Batterien zu gehen. Dank deiner Drehmoment Messgeräts-Empfehlung war das Lösen und festziehen der Schrauben an den Batterien recht einfach. Ich hatte echt Angst vor einem überdrehten Gewinde.
Damit werden hoffentlich die Batterien immer gleich im oberen Segment belastet. In Reihe ist die Batterie leider nur so gut wie die schlechteste Zelle.
Working on catching up
Your doing a fantastic job thanks
Looks like a good product but it says it needs a 30V external supply voltage for anything under a 10S battery pack. Those of us with 8S 24V battery packs have to wait for an 8S version.
I’m wondering about this myself, says it can be used in smaller configurations but with external power, but, I see no extra connections for that??
congratulations, you are very good and attentive and explain everything in detail
Good morning, is it possible to know how to install the cell management program on Android, thanks
Thank you for your feedback. You have to download the app as a APK file and install from there on your Android device. On your mobile phone it will prompt you to allow installing apps from a third party. Once you allow that, it should install.
What is the difference between third generation and fourth generation?
I received the NEEY 4A with a June 2022 label, I don't know what generation it is.
Que diferencia hay entre tercera generación y cuarta generación?
He recibido el NEEY 4A con etiqueta Junio 2022, no sé que generación es.
I think it is actually better to charge and discharge only the one lower/higher voltage cell at the time so the voltage difference in the pack will be as smaller as possible!
Sir your videos are very good and you also talk very well. I watch your videos everyday. love from India 🤍🤍🤍
Hi, I met you a little while ago and congratulations for the excellent explanations, I wanted to ask you a question, I installed a 10A neey in my 2p 16s, but I am forced to keep the neey at 2A working, if I raise it for example to 4A or even more, it brings the cell voltage to 3.80V, therefore too high for the lifepo4 and the BMS disconnects the entire system, while if I make it work at 2A or 1A I reach a maximum of the cell higher than 3 ,60V and therefore I have no problems with the BMS, in your opinion what could cause this problem? thanks and congratulations for the beautiful channel
Andy, did you ever test the QNBBM active balancers? They balance all cells concurrently to a 10 mV deviation with up to 5 A. I use them since more than 5 years without any problems. Of course, it isn't smart, but the BMS is showing all the cell voltages and the effect of balancing.
Never heard of them before. I'll have a look. Do they balance all the time, even at low SOC?
They do balance all the time, but only if the difference is larger than 10 mV, so they avoid unbalance in the flat area, and help weak cells at lower SOC. This is similar to a combination of top and bottom balancing. They can be cascaded for any number of cells.
I think the advertised 4A is a bit misleading. Half of the time it charges the cap and half of the time it is discharging the cap. So this is only 2A in average. Additionally it is checking the voltage and switching off the discharging of the cap while doing that. So honestly it is only a 1-1,5A balancer in average.
It’s actually worse than that because he said it is charging for 1 minute and discharging in 30 seconds so it’s actually 1/3.
As always "BRILLIANT"!
Good demo. This means there is no need of connecting cells in parallel for voltage balance? .
Excellent video thanks for sharing
Would you please note or show exactly which android app you are using in the video. Great information on your site.
There are a switch vias on the Heltec balancer PCB. You can either install a physical switch or automate it. It only stays on all the time because you are not using this switch. It's labeled "run" on the PCB and the two vias are soldered together (NC).
How to find which generation NEEY we are buying , any label /version printed on product?
I suppose that these capacitive balances must use a boost converter to charge the cap. Hence why it takes longer to charge. My jtek works the same way.
Yes, they must have something like this, otherwise it would not charge. Both batteries have almost the same voltage.
Hey Andy, I send you an eMail with some screenshots showing crazy behaviour of the Neey 4th Generation Balancer. My one is taking energy from the lowest cell and transfer it to the highest. The opposite of what a balancer should do with the battery. The battery is totally imbalancing, when the balancer is turned on. I think the chinese guys build the first imbalacer device on the market. :-)))
Hi Andy,
Actually there is already a 10A version out on the market (branded JK, but NEEY representative told me that it's also developed by them) AND a 15A version coming up in a few weeks from now ...
have you also tested the 10A version ?
Grüsse aus Bayern
Hi Mike, I've tested the 10A Heltec balancer only so far not the one which can be programmed. Maybe I'll ask Hankzor to send one over for a testdrive...
Purchased 4th gen. 8s config. Flashing red & blue lights. No connection to app.
Trouble shooting says check wiring and cell count setting.
Wiring measures correct.
Cant check setting without app.
Can find contact for henin company / neey.
Feeling stuck.
Check the balance cables again if they are in the right order. This is very crucial and if not connected correctly, it can cause such trouble.
@RichardBaileyrichoncode I have the same problem. Have you found a solution? I am using a LiFePo4 16S (48v). Black to the minus (-) and last balance cable with the red positive (+). Beeps 3x short 1x long. Blue and red LED flashes. App says "Failed to information". @OffGridGarageAustralia HELP!!
@@martijnduim4413 no idea, no experience with that, sorry. Usually the 3 beeps are a confirmation that is it running.
Have you tested the new app as well? It's linked on my website under the NEEY Balancer: off-grid-garage.com/battery-management-systems-bms/
With this one installed one does not need to pre-balance the cells before assembly?
Hi Any chance on a tutorial or just a pointer on how to find and install the app? i thought installing the balancer would be the difficult bit!
I've got the app linked on my website. Link is in the description of the video.
How about a diy option, where you use the capacitive balancer with a voltage relay trigger ? I have done that - but you need to be careful with the voltage relay trigger as the voltage measured is inaccurate . Would be nice to see a comparison as the voltage trigger is only about 5USD.
Hi Andy I love your videos. Where did you get the app and instructions fore the 4th gen neey. Thanks
Excellent
Thank you! Cheers!
Re 30V supply. I just received my unit and noticed on the box it says (for the power supply) 25 to 100V. I downloaded the latest PDF from github and it also says 25V (used to be 30V). I contacted them to ask about the 25V and also what happens if the voltage is below that. I hoped they would say that the unit just stops working. They replied you can now go down to 20volts and also 8S (rather than the previous 10S). That's great news for me as I was interested in 8S.
I have been testing with an 8s 460AH LFP bank and no external power supply. Furthest I have been down so far is 25.4V and I can confirm that everything continues working fine with the NEEY and that voltage. I doubt my battery will ever get below 25V to test that so I'll leave it to someone else to try. That would be a pack with each cell at 2.5V.
Thanks for testing this and sharing your results. That's good to know!
Thanks for this! I still wish they had an 4s-8s model with a bit lower price, since I also have two big 8s lifepo4 24v batteries.
What is up with the iOS app? ALSO, I have blue flashing light, it beeps 4 times then middle red flashing light…won’t connect to app, so I disconnect the BMS, not sure if the beeps and red flashing are an error, but I have checked the wiring and it’s right…8s LFP.
In the 4th generation of the NEEY, do they use the average ("feature" of the 3rd generation) or maximum cell voltage to start the balancing process ?
Does it have the protection if the wires are not correctly connected?
Can I borrow Andy 2 for my PV installation
I'm still looking for the Android app. Google Play doesn't seem to have it.
Good morning, is it possible to know how to install the cell management program on Android, thanks
Hi Andy Had to get your attention because your endorsing the Hankzor BMS Store.
I have had a bad experience with them. From your infamous NEEEEY video's, I learned I don't have version 4.0 which I ordered because of missing new app. features you showed all of us.
I purchased two units, each at a different time, turns out they both are version 3.2.
I want to share with you and everyone the truth about the store including the "off grid garage" youtube channel. I asked the Hankzor store repeatedly about this, but keep getting the run around why the missing features in the app. They said v4.0 were sent. I have now leaned they lied.
Thanks Andy!
Two questions Andy, if I may?
1) I am in the market for a good balancer for my 280ah bank since I added 3 more cells to the 15, as balancing them manually is one huge effort. Is the Neeeeeeeey definitely the best buy today to compliment my big model JBD BMS?
2) Your system settings on your website, are they up to date? Can you also post your inverter settings ... and the Neely settings? 😊
Going to get one of the 8A and/or 10A models? I just picked up a 4A version as I figured that was plenty but curious if the 8/10's behave any different... They have a new app they're working on and it seems incomplete, password changes don't work.
Very good :-) i have a question: what is the hardware Version, on the PCB is "V2.9 ", is that the 4th Generation?
Hi and thank you for your videos . Please can you explain me how I can change the ah in the settings to 280ah . I can only change to 200ah over that the set button goes gray
I don't think the caps would fully discharge, it would only discharge the differential voltage between the high voltage cell and low voltage cell until they become equal in voltage otherwise you would need a buck-boost converter built into the BMS to fully drain the cap
Hi, Your video is much helpful !!
My nㄷey machine is showing a different value than the actual battery cell volts. My machoine shall be caliberated. Do you have any idea hwo to caliberate voltage ?
I think you missed a great opportunity to show the active balancer to properly balance the cells over a 7 day period. And you say it was a struggle because the power supply had to be adjusted manually because you didn't want the BMS to cut off charging. IMO, if you just set the power supply to 58 volts and turned on the NEEY active balancer you could have easily recorded the PACK DELTA day by day and it would just keep chugging along with the BMS doing its job by turning on charging as the HIGH cell gets discharged into the LOW cell and then WE could see how the voltage DELTA changes each day. Why don't you trust the BMS? You are so safe with the charging voltage on your power supply even though the BMS is hooked up?
I agree. What would also have been interesting is having this compared with the current champion BMS (JKBMS) in your setup…
I’m finally ordering my parts for my big battery and I think having a decent BMS with all the best functions far outweigh a dinky BMS that needs to be babysat by ancillary devices to cover its shortfalls…
JK BMS for the win until further notice
@@riaanstrydom2183 absolutely, smart bms with real cell balancing is a must
Hello everyone What does it look like if the + pole (red wire) is installed with a fuse and a switch.
how do we know we are getting the 4th gen? will it be mentioned on the box?
Hi. My Neey V4 Balancer passes away after 2 month of "Work". Chinese Service (HankzorStore) is Zero. But I think Seplos with good balanced Cells will work well without Neey V4
Looks like a good option. Might need to choose between this or the jkbms
The JKBMS is a BMS with active balancing. The Neeey is only the active balancer, it is not a full BMS.
@@CollinBaillie yep aware of that. I have 2 cheap batteries that have no Bluetooth, active balancing or adjustable details and just a shitty bms. My thought could be to add this neey or replace the bms to be better quality and have the active balancer built in.
JK BMS 150 or 200A with2A balancing will work in most cases. These are nice to keep around for those difficult runner cells.
Hey brother can you tell me if this is a model/brand you are still recommending we use ? And one more question if I may, does this require and external power supply to operate ? The reason I ask if because I intend on using a balancer for the lithium in my car and if it require and external power supply I don’t know how well it’s going to function if I were to give it power from the same battery in which i intend to balance from ?
I've been following your videos for a couple years now and have taken your advice several times. I've just received the NEEY and am going to try it out. One question I have is, should the balancing be turned off on the BMS? I'm using a JBD 200A
I turned mine off because I saw no reason to leave it on, it's passive balancing so it is a little bit of wasting energy
Maybe they should put two Super Caps that work independently. Then you could balance 4 cells at once . Discharging 2 and charging 2 cells at once. I think only for batteries with more than 12 cells. Awesome product tho.
Hello Andy,
I would also be interested to know what data is displayed by the software on your Neey balancers on the "System Info" tab. There is the hardware and software version.
Greetings Ralph
i have a 3-phase multiplus ESS system with 4pcs. exact the same 200Ah/48V battery packs. when i connect the neey to a battery(no matter which one), one cell voltage rise over 3.65V volt in no time. limiting the charging power to about 150W prevent from overshooting the cell voltage. any ideas why this happened?
Love it! So funny!
nice, now they have to work on the price. $70 is just way to expensive for me.
What would you recommend between the NEEY and the JiKong to charge LiPo4 now that you have good time on both active balancers.
Also, regarding the JiKong, do you think it would be totally fine to remove the large black and blue wires and just use the balancing part of the unit and leave an MPPT to provide direct current to the battery?
I will see what the smart JBD BMS reads and plug in the Heltec 5 amp balancer and see what the numbers do. That's the plan anyway.
Hi,
I write from France and I have buy this device as soon as possible!!!
Error with 4S 12.8V battery
How to do with a 4S 12.8V battery?
Power source?
Ok, but like what?
Or another battery balancer but which one?
Thanks for all
Brice
Where in the world can you find the neey app for an iPhone?
