I have send the updat to Rick, so he will forward it to you, there is no attacment ikon here.

12 + 11 What is the Master BMS serial? I have to send you the dedicated firmware update.
The power line that continues from sub-pack to sub-pack from batt- to bat+
Do not worry. We stop balancing for measurement. Keep the wires 90° to the power line so you minimize the EMI. Keep the loops as small as possible. @ Rick I just finnished writing the code for ...
Well we can write the code for 2 Serial Slaves for SMA SI. We have it for Victron already. I strongly advise not to use Neey BMS in conjunction with REC. This is why: it introduces measuring err...
Resistors are 330 Ohms. Maybe there is a bad connection from the cable to the crimp or fronm the crimp to the pin.
Rick and other users gave me thinking about how to change this sound buzzer alarm not to drive the users nuts. Let me describe you the solutions from my side and please send me some comments or sug...
R46, R47, L2, C52-C54 are the input filter for the current measurement. maybe you are getting something via burned PCB
It is not the matter of code or hardware, otherwise the > 2000 people will send me emails. It may be the thing of wiring and component placement. Like on this picture. See how the battery and th...
The alarm is trigered the same way but only the ERROR LED bliks, error/warrning 7 or error/warrning 5. No sound alarm, no alarm sent over the CAN. I tried to send everything over the CAN bus to Vi...
Also with the 2Q, the alarm for the LOW temp for charging and high BMS temp is silent. 2Q has an aditional algorithm to lower the amount of cells to the most critical, not to step over the BMS max ...
The old CAN protocol for Victron had this eatures for Warrnings. I have mooved this from the code if a lot of ballancing is required the unit heas up. The balancing is reduced near the top end but ...
Yes, you are right. IT is a firmware bug. I have tested this in the morning. If you set it to °F then it gets data from the entry window and sends it directly to the BMS without converting it ...
@Peter Well The resistors inside the BMS are 4Ohms, this means when balancing @ 2.5V that is minimum threshold it would be 0.625 A when balancing, but actually a bit lower since the BMS perf...
If the Cerbo is also powered on the system side then it does not get the data from the BMS when disconnected.
Charge current is only set to 0 A when the temperature goes under the Under-temperature for charging. Contactors are ON unless you select them in the TASKS for the charge relay 1.
No can't do. It does not work like this. Victron CAN bus protocol was provided to us and all the CAN data is supported. To get the Time to go, they would have to add this feature or a programmer sh...
@Christopher Is the Quattro connected to the BMS via a contactor. IS the contactor in positive or negative?
Disconnect everything from the shunt consumption. The current should show about 0.0XX or negative near zero. I do not see clearly if this is 500A/50mV shunt or 300A/50mV shunt. First check/se...
Does the ABMS show correct current (0 A) when all is disconnected? IS the shunt connected directly to cell 1- pin or via fuse or ON/OFF power switch? What avout the cable from the ABMS to the shunt...
You can open the ABMS and see if there is a ISO1050 (U5) mounted on the PCB. It should be, since we started to put them as a standard from 1-A-0470 onwards.
