    okay, I'm really close now, there are only a few places left to find out ~22014A00E0C600 2710 SoC value 10000%/100 14E5 batt volt 5349mV*10 10 cell count 16 0D13 cell01 3347mV 0D07 cell02 3335mV 0D08 cell03 3336mV 0D0A cell04 3338mV 0D08 cell05 3336mV 0D0E cell06 3342mV 0D07 cell07 3335mV 0D0C...

    @DrSolar I see, I still have one or 2 unknown parts in the information packet from the BMS, maybe it's listed there, I have to check it :) It looks like mine is similar to the Pylon protocol, but actually different order and partly different data :) @Jaxonwood: currently I have planned nothing...

    Hello all! I just had to register because I am stuck with my problem. I get me a LiFePO4 battery from aliexpress (I can post a link if needed), it's quite nice, but it only communicates using the windows software you get from the vendor. The battery can communicate with diverse inverters, so I...

    ohh, I will try that password later, can't do it right now :) for me it works fine now with node red. the few missing (or unknown) values are not important for normal use
  • Post in thread: BMS protocol and read-out

    since it is new to me and to understand it better: So it is as you said? I have to convert the buffer to ASCII which then contains hex values which I have to decode to 16bit numbers? (well, it might contain status bits somewhere, too, no idea yet) I think I made some progress, 2 data packages...

    ok, that's interesting :) the hex values (of a new data packet) are ~22014A00E0C600271014E5100D130D070D080D0A0D080D0E0D070D0C0D180D1A0D090D080D070D080D280D23012C0122012C04012C012C012201220000000000640128CA28CA0006000000000000000000230000000000000000000000000000000000000000000000D56C in ASCII

    I have the software, too :) but since it runs on windows, I can not use it with my Raspberry Pi but beside this, do you know more about the settings you can adjust using the software? I did not play around with it yet because I don't want to f*ck something up :> I also noticed that some fields...
  • Post in thread: BMS protocol and read-out

    so, you won't believe it but I just now had the time to try the password in the BMS software and to read the posts that have been written here after my last posting, lol ... and the password works! :D But did anyone of you try to change some of the BMS settings? There's the "start voltage" (I...

    @mlamar my battery currently is at 60.5% and 52V while ~8.7A flow out of it 45.2V seem a little low IMO
  • Post in thread: BMS protocol and read-out

    hehe, don't get me wrong, but 200+ mV difference between cells is a no-go ... lol imagine, 3.5V is full, 3.3V is nearly empty ^^ I think the BMS may actually work now :o at least I saw the lower cells charge and the higher cells discharge today while being in CV mode with my charger. I have to...
