I use this RS485 to USB cable. However, it only works in the RS485 socket next to the CAN. The RS 485 in the double pack for the battery paralell connections does not work with it.

I think JK and JBD are equally good. The cell balancing current is a little higher with JK, but the parallel pack current is higher with JBD. I switched off balancing with JBD because I treated myself to an external balancer with 5A balancing current. This balances not only at the end of the...

The PC software you are using is only partially suitable for the JBD UP series. In fact, some things are greyed out. This is not greyed out in the version UPseries_BMS-JBD-Tools_v2. 7-20230407. Try changing the parameters with it...

I have been able to solve all the problems so far. The JBD BMS works much better than my old Daly BMS with Victron. I have a Cerbo GX no Venus Os. VRM recognizes the battery as a Pylontech product. Apparently the CAN protocol is the same. Charging and discharging currents are displayed. The...

Thanks to Wuerzburger, who found this new JBD tool. With the new JBD tool, the question marks have been translated into English. Now I have been able to solve another problem.

Here you will find some very important information about these question marks. Very important values must be entered in these question mark fields. Chinese, how do you think we are going to deal with these question marks? This is where the charging currents and discharging currents for the...

I don't think they do anything to each other. Real Chinese philosophy. Good products and also a very bad service and support. Before JBD I had Daly🙄. With a lot of patience I managed with Victron. But it worked more badly than right. There was no help from the manufacturer. That's why I switched...

Problem solved! A different value must be entered here where "Current mR" is circled in orange. The default is 2.5. I had to enter 0.1. The BMS then displayed the current. I also had to set the current to 0 when the battery was full and no current was drawn from the battery. Calibrate. Now the...

Thank you very much, I have downloaded it and will watch it today.

I am currently in the process of marrying this board with Victron. I will let you know what is shown and what is not. Be patient. You have to be patient with this board, says a dealer in his sales description. 😅The BMS board seems to be very innovative, but the description and operating...

The balancing of 20A refers to the balance between the 48v battery packs. It is not the balancing between the cells in one of the 48v packs. This BMS board also has the cell balance of 50mA, but can also be switched off if you want to use an external balancer for cell balancing.

This JBD BMS from the UP series is designed for multiple battery packs. For example, you can switch two 16s battery packs in parallel. However, you need a BMS for each pack. The advantage is that the packs are balanced. The balancing current for this BMS is max. 20A. This is already very high...

Hello Würtzburger, please provide the link to Aliexpress

Der an J11 angeschlossene Power ON-Schalter funktioniert nur, wenn er in der Funktionskonfiguration (KEY-DEFET) aktiviert wurde. Leider musste ich das durch Ausprobieren herausfinden. Viele Funktionen sind mir noch nicht klar. Hat jemand eine bessere Beschreibung der möglichen Funktionen?

The battery measurement cables 1 and 3 each have a cable to the negative terminal of battery 1 and battery 9. I am using a 16s battery and when I connect the cable from measurement cable 3 to the negative terminal of battery 9 and the BMS software displays 0.0V on battery 8. If I remove the...

Hello, I have a JBD BMS 16S 200A of the UP series and have the following problem. The BMS does not display the charging and discharging current. The PC software shows 0.0A. The transmission via CAN to Victron Cerbo gx is also 0.0A. When the charging current goes to 65A, the BMS shows 2.3A. What...
