Daly Smart BMS - odd behavior

Yes it is confusing. But DALY shows it like this. Minus amps when the battery is charging.

What is perhaps worse is that their PCMaster software V 1.2.5 does not show up any English - only Chinese!
I have upgrade the only working BMS as requested from Daly from 2021021-1.01T to what WAS the upgrade which worked, then the 20210222-1.01T which consequently saw the BMS acting up with error messages and neither software V 1.1.5 or 1.2.5 giving any readouts.
I decided to try and 'Upgrade' back to th eprevious version and thank g### that was accepted. Readouts on PCMaster 1.1.5 are good.
1.2.5 never worked and it was all in Chinese anyway. Duh.

Daly are changing the firmware and software far too often! 3 times in a few month - no wonder many are having issues.

They have offered me a 2nd replacement (Original packed up, replacement packed up within 30 minutes?, and now maybe another on the way - but i still have not seen any refund for the 2 failed units. I have told them to refund me for the 2 faulty units and then i will order the new one. - long story of order anad we will change the price to basically zero - but never happened!) Very strange way of doing business in my opinion.

The good news is that if a firmware upgrade fails!!! you can revert back by loading the previous version assuming you had the file in the 1st place.
Dont trash any of those older files, just in case.

I cant get an answer from them as to where i get updated firmware. Also when trying to deal with them with issues i just get the same questions asked back to me on a loop. Have told them i want a refund for all the issues im having and i just get asked “is it working” over and over.
 
You can download the latest PC software here. It is 1.2.8.e

I have no problem with my 16S / 250A DALY Smart BMS with firmware 20210222-1. I read every second all necessary data from the BMS via RS485 with my M5Stack and convert the data for the SOLIS Hybrid Inverter and send it via CAN to the SOLIS. This has been working for several weeks now without interruption. I am very happy with this configuration.

do you know where to get updated firmware for the bms? like when they bugfix
 
There is no download page from DALY. You have to contact DALY support. But it takes a lot of work (email) until you get the new firmware from them....

This is the latest firmware I received directly from DALY support. I have only installed and tested it on my 16S 250A DALY Smart BMS (hardware version: DL-BMS-R32-01E) and it runs very, very stable. No problem at all for me. I use the RS485 communication port every second to read some important data.

Attached You find the actual Firmware. Hope it helps. Use the newest PC Software 1.2.8 to install it.

will the same firmware work on the 8s 400a smart bms?
 
I do not know. But if the hardwareversion ist the same, i think so... HD-Version: DL-BMS-R32-01E

I've been using Daly Official store to buy and subsequently obtaining new replacements - waiting for the THIRD one coming on 3 weeks time.
Daly offical store Joyce, seems to have language issues which i can understand. But their system i not like our western world for sure. Very thrustrating but i've held back my frustrations - and i am very slowly, getting replacements. If this next unit fails - i'm off and will be looking for non chinese build. Found one that Will has recently shown - American company, but they admit its made in China.

yes i have found the response from daly to be well.... useless. i present issues and all i get is the same 2 questions back. stuck in a loop.

Sounds like then your unit is faulty.
i tried all the online methods that i am now sure were for the older or non smart models and none worked, even the button o the light board did not activate the bms.
In the end following the reallllllly bad instructions in order and deciphering that they meant to use diode mode to activate the bms and the resistance check does not activate the bms its just to check for a fault.
I spend like 5-6 hours every time i needed to re activate trying to get it to work untill i found this.
I also found if it failed to activate the first time i would ned to unplug and let it sit for about 10 mins for the caps to discharge and reset the memory inside as i think if you do it wrong the bms wont activate as i goes into some sort of protection mode. i think,

Similar story here timmeh. I left the unit disconnected over night hoping that caps would discharge, any memory would disipate but it still would not fire up. The Instructions are dismal and simple. No problem solving on the simplest level either.
Then the software is showing (at least on mine) 60% plus chinese!!
Waiting for my 3rd replacement unit to arrive.

Have checked every wire 7 or 8 times now!! i must be getting bored - but no faults of any kind.
Good luck m8

Don't forget to quick short the P- & B-. If that doesn't work then kickstart the bms with a powersupply with somewhere between 14.6-14.8v. They're all different at which voltage the kickstart kicks in ;) (mine was 14.8v)
 
I have a Daly/Mgod BMS 10S for LTO and used for like a week, and then I encountered the same problem. My SOC stuck at a bit more than 30% and when charging with quite good power and current the SOC just won't move. While the cell voltage and pack voltage contine to go up.

Anyone has figured out how to solve it?

(Just so you know, I have top charged it days ago and set the SOC to 100% by then and also set the capacity correctly (90Ah))

Well that is unfortunately not what you suggsted here and perhaps you didn't check my graph carefully. I uploaded 2 more pics. The left graph shows the SOC and the right graph shows min/max cell voltage. If you know LTO well then you know it has been changing something like from 50%to60% up to 80%. It was charging with 200W in the middle of the day, and my battery pack is only 2KWh capacity. So it actually charged around 10% per hour during the mid day. Or you can view it directly on my shared dashboard above and click onto the advanced tab. It has been charged with more than 8A from 12:33 until later after 5PM the sun goes down, the SOC is capped and not moving at all. This is a firmware bug, I suppose. And I could not get any help from the seller than telling me "top charge it and then set SOC to 100% again". But I already did exactly this 2 or 3 days ago as it was way off and capped at 49% for some reason by then.

I feel Daly's BMS's software side (also they cannot read current blow 2A) is not polished and just a "fancy look" product. I then ordered some QUCC BMS and they arrived today and I set it up earlier on my other battery pack and they work nicely (amps reading can be as low as 0.5A). I haven't figured out is how to set the SOC on QUCC BMS yet, as it is late in China now, I will ask the QUCC seller tomorrow. (Their tech support, or the seller, is also much better)

From the software config page it feels the Daly system is doing very stupid amps monitoring and calculate the SOC solely based on that. It considers nothing with your voltage change. The QUCC BMS seems doing it more "smartly" or what I feel is the standard way of estimating SOC - you combile amps reading and battery voltage reading.

There are also large current fluctuations shown in the app, which are not present. My Victron system and separate Victron BMS both show pretty stable levels while the Daly will be showing +-30A fluctuations.

Anyone have any experience like this? Or able to suggest a remedy:)

Have you been able to fix these current-reading fluctuations? When I have a 60A load via the Victron inverter, the Daly Bluetooth app shows anything from 1 to 150A.
 
I have a Votronic shunt. The reading on the shunt correspond to the readings on the app.
 
WOW!! 0.05v

Reference voltage is 3.20 Volt (LiFepo4). SOC You can set to 100% if the Cell are about 3.45 Volt. All Cell must be first in balance. Attached You find my Screenshoots. I have 180Ah Battery 16S at the Moment. The language is german, but i hope it helps anyway..

Damn!! you have a differential volt of 0.005v. how did you achieve that?
 
@fopoku2k2

1. Good Calb cells 180Ah
2. Perfect TOP Balanced cells
3. Perfect contact on the busbars with the M8 screws...

Even at 76A charge current, I have less than 10mV difference as long as all cell voltages are below 3.40 volts. After that, the deviation is up to 25mVolt. I stop charging at 3.426 Volt at the lowest cell. The highest has then max. 3.450 volt.

Hello everyone, I'm new to that forum and need help please :)

Got 8 x CATL 280AH (actually 272AH) 3.2v cells and a 150AH Daly BMS with Bluetooth and all are set up but need help with correct settings as default come with default setting so can you help me... run 24v system so can you help me correct parameter setting for eg i saw on first page on this thread...

1. Cell volt high protect : 3.65 Volt
2. Cell volt low protect: 2.80 Volt
3. Sum volt high protect: 14.60 Volt
4. Sum volt low protect: 11.20 Volt
5. Cell reference volt: 3.20 Volt (this is for LiFepo4 Cells !)
6. Sleep waiting: 65535 (This disable the Sleep Modus forever)
7. SOC: Set this to 100% if all Cells reached 3.45 Volt. At the end of charging, the voltage ries is very fast....
8. Balanced open Starts: 3.400 volt (Means only Top balancing)
9. Balanced open diff voltage 0.020 Volt

So can you help me for 24v setting, thanks!
