For your information, I paste the chat with the "official" seller to whom I am telling that according to the opinion of several experts this BMS does not work. Is it normal for you that the chat develops in this way? [06:50, 7/11/2023] Alvaro Nannicini: " hi,dear,don't worry,i will help you...

Thanks, unfortunately at the moment I don't have a notebook available, at home I should have some still working desktop PC to put in the garage, and I have to find the interface to connect it, I hope I can do it but it takes time, bye and good evening.

After the night all the cells have this graph But cell 1 has this graph Now I try to replace the terminal that goes from pin 21 to the negative pole of the battery pack. Is there a way to reset this JBD BMS? I wouldn't want to waste entire days and then discover that the BMS is broken, do...

Hi everyone, this morning at 5.30 I started to recheck the connections, still following the wiring diagram and they were all perfect, I rechecked the continuity of the small cables pin by pin by disconnecting them from the cells, no problem but in any case I followed your advice and reunited the...

Thanks, after I checked all the cables and the incremental voltage on all the batteries I try to do what you said, but I don't understand the difference between connecting the 5 cables that go to + 14 with their 5 terminals and connecting them all together on a single terminal

The BMS cables B- and C- are NOT connected to the negative pole battery, the ones you see in photo 1 are the inverter and 2 MPPT cables Cell 1 volts and battery pack volts. As I said the system has been working well for 6 months but I didn't tell you that you are talking to a 73 year old...

Last night I checked the wiring again and in fact I found that the red cable of pin 14 that goes to the positive pole of cell 14 was interrupted and the situation has changed: Without pin 14 Without pin 14 and with pin 14. I measured cell 1 with the voltmeter and it has the same voltage as the...

Hello everyone from Alvaro, Pisa Leaning Tower Italy. My home-made off grid system has been working perfectly for 6 months but I don't know if the 16 48V cells are in good health. 5 months ago I bought the JBD BMS but I couldn't make it work, it's probably me that doesn't work :-). In Italy it...
