thank you very much, I am working on getting the correct protocol of these batteries, I will let you know if we get it, your capture will be very useful, thank you very much

hello, this is very interesting, unfortunately I don't know how to handle it, but I'm going to send this information to some friends, have you got any progress?

it does not matter if you use a power supply or a charger that is capable of giving 200a, when the voltage is close to the established one the amps will go down, and it stays like this for many hours, according to what they say in the forum we would be damaging the cells.

Hello guys, I've been thinking for a long time that I was doing things correctly, placing the cells in parallel and charging them at 3.65v, advising my community colleagues on how to do it, following everything I have read about it, and seen in many videos from different channels, including...

I would trust jk more than heltec, since jk is the real manufacturer. heltec is just a rebranding...

Give me a few months and I'll tell you how they're doing, and a few years to really find out ...

in my group we are waiting to receive about 500 cells among the colleagues, when they arrive we will do tests to see the capacity, I have the checker EBC-A40L, I'll give you the results

yes, heltec simply sells bms and accessories from other brands as if they were theirs, such as JK and ANT

yes, you could also plug it into the connector designated for the pc marked "monitor", as Just John says. I would like to see the data in home automation with home assistant, but unfortunately I am not trained to configure that, I need to learn but I have little time for it ...

I have two firmware, one for bt work and one for lcd work, I have tried both and they both work, I can put one or the other without a problem, if you want I can give them to you, but I am not responsible for what may happen. ;)

Yes, it is already solved and I can communicate with the pc, it was a configuration problem. Now I have another problem, they have provided me with a new firmware to operate the LCD and the monitor port at the same time, and I can see and configure all the parameters from the pc perfectly. The...

my 4s 200a bms does not have the same connector arrangement. nor does it have any character in Chinese. maybe you can use an ocr translator to know what it says there. What I would do is ask daly about this though.

RS485 a and b are crossed for sure? i think the crossing is only at uart, but i'm not sure.

thanks, this adapter is original from Daly official store? because mine is completely sealed in rubber, nor can I open it unless I break it.

sorry, the translator of the page has trolled me. Could you show the ic model?

this is the pinout of this conector. But not same as @Kapo BMS

¿Podrías mostrar lo que pone en el ic? Thanks

according to the bms, if it has the 6-pin connector for the soc led monitor, the meter has a power button, simply push ON button and Bluetooth come ON. If you have the connector but you don't have the led monitor, you can still put a power button on the two corresponding pins. My bms 4s does not...

I did not think to buy there, I am only giving the information I have about the supposed 300ah cells in that company, because I have not seen another that offers them, to try to clarify what cells they really are.

the two pdf that dongguan Huanhuan sent me.

I have asked for a price in Dongguan Huanhuan Energy Technology Co., Ltd. and they have offered me these 300ah cells, they say they are catl, I have asked for the datasheet and they have sent me one in Chinese that does not say catl anywhere. Later I asked them if they had it in English, and...

I thought this balancer was better, which one do you recommend quality / price? I only need for 4 cells and the active balancer of jk costs about 100eur, it is expensive for only 4 cells, if I had a bank of 16 or more cells it would be profitable. but it hurts to pay the same for the same device...

I have gotten these images of the Daly 4s 200a pcb, I confirm that by putting a switch on the two-pin port (key + gnd) you can activate the bms and activate the bluetooth when you are sleeping, in this way you do not have to leave the bluetooth always on.

I think now I understand it, you have to put 15300 or 65535 in seconds, but keep using the code 123456 to validate the changes. I thought you had to put a different code than 123456 for that.

Thanks for your answer, if you read the previous comments there is a master code to disable the standby timer of the bluethoot, according to the colleagues it is 15300.

I've been wasted all day trying to connect my bms to the pc, with the sinowealth software and usb rs232 and TTL adapters, they are not the original daly USB UART, someone knows the real pinout of the connectors of this bms, it is 4s 200a with fan. And how do you disable the bluetooth sleep with...

What is that monitor cable you have on, could you show it in full? Thanks

What happened to this thread, I just discovered it and it seems very interesting to me, because I bought a daly bms and it makes me want to throw it off the balcony, it's bad bad, meaningless ports, I don't know if it's on or not, app bad, disgusting.

my smart Daly 4s 200a does not let me change the parameters, I use the latest application available in playstore, version 1.7, I put the. code 123456 but it does not apply the parameters that I indicate. is there a better alternative app?

I like your project, I was thinking of doing something similar with an esp32, I'll stay here to see how it evolves.

speaking of which, does anyone know what material are the busbars that BASEN delivers with its cells?

I have exactly same models, wait for epever answer, thanks.

What exactly is that bms? Can you give me a link? Because I mess with the products on the heltec website, they are not well defined

for that I will have to buy it first, and that's what I don't want to do hahaha
