I don't see where you checked the crimps on the pins from the shunt wires going into the AMP connector.  We had a bit of trouble with those in the past.

This sounds like a processing issue.  Try this Connect to wifi module Go to Firmware page and log in scroll down to Manual commands Enter address:  1 for q/2Q  2 for ABMS Enter ...

I've been wanting to verify and adjust several unlisted settings such as RAZL.  When I attempt to do so using the dialog box on the Firmware screen, I get no response.  Not only that, but...

@tine , @Rick I owe you both an apology as I have only now gotten to running through Tine's trouble shooting steps.  The 50+ amps showing as coming in hasn't caused an issue so I've not made ...

I was hoping that someone could explain how the REC-BMS logging screen works on the WiFi module. For exmaple, if the logging interval is set to 10 minutes, does that mean that it records a new data...

@Rick I will solve this problem faster myself because I do not count on the help of the seller or manufacturer.Zeus is an interesting product, but there is no technical support.

@William In the end I was able to have 2.5.1 working well, as I mentioned in the previous post, no complaints. And looking at the release notes, it seems that 2.5.2 is mostly about Victron DVCC and...

I just figured out that the most current software is 2.5.2.  Do you have any idea if it fixed your NMEA 2000 issue?

Chris, I have not had any luck contacting Zeus either.  Your selling dealer should be able to help you with this.

@Rick Hello Rick, have you replied?I have already written three times and have never received a reply.

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...

Sure, you can have a different ground potential across your boat, especially if you have some things bonded (connected to an anode) and that ground difference can induce an offset.  A non-isol...

Thanks @Rick. There are no A/C lines anywhere nearby. Would you mind explaining a bit more about network devices that might be causing a ground loop? I will take the connector off and check for ba...

Yes, the WiFi module supports both connection to the BMS as well as the older LCD screen

It sounds like it may be one of 3 issues: First power down the BMS, remove the AMP connector so you don't damage the BMS circuitry and check for a loose or corroded connection somewhere like on ...

I have a Rec Active BMS with a 3P4S EVE 308Ah setup on my sailboat. I installed the system last October, all 12 cells were top balanced to 3.65 before installing. About a month ago I noticed cell ...

Hi, Is there a way to have both a Wifi module and a REC LCD screen connected to a Mater BMS system at the same time?

If 183Ah use, SOC should be only ±85%??? 100-(183÷1200x100%)

The Ah use doesn't seem make sense while SOC is 97%, 3% of 1200Ah should be 36Ah instead of 183Ah

I set my battery capacity at the above circled spot on the PC software.  After set up there it still show 800ah on the phone app.

Thank you very much .   Maybe they have specific settings, Zeus connection via Cerbo Can port, settings compatible with REC BMS  

Hi Chris, We sent a REC Active BMS to Arco last fall and they confirmed that it was working but we havent had a chance to test that configuration yet.  I will reach out to them to see if they...

Hello in the topic of Arco Zeus, today I tried to synchronize Zeus with REC Active BMS which manages the entire Victron system via DVCC.Unfortunately, connection (synchronization) failed.Thank you ...

Hey Fred, yes we set it to Li-bmx-ext. I erased and reflashed the update.bin file on the master and it's working now.   Haven't heard back regarding the grid export but I did forward the abo...

@tine As I move the wires around it does go all over the place so fingers crossed it's just the loom. Any chance of getting hold of a spare board and cable to be able to rule out one or other 🙏🫶

R46, R47, L2, C52-C54 are the input filter for the current measurement. maybe you are getting something via burned PCB

That brown mark doesnt look like an issue. Did you ever check the shunt wire pin crimp connections? Remember, you are dealing with millvolts and any poor connection is suseptible to induced galva...

Still pulling my hair out though I think it's the cable..... I have opened up the BMS and have continuity between pin 24 and 25 of the main connector back to R46 and R47 R46 measure resistance of...

did you use the CAPA parameter to change your capacity?Go to the manual commands section in your wifi or PC software and try:   CAPA 1200    <enter> it should respond wi...

I have a REC active BMS on my 800ah Winston cells 2P4S setup.  It's been working great, SOC match my Victron BMS, cell being balance ... However after I upgrade my battery bank to 1200ah, 3P4S...

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 ...

@tine That is interesting, thank you for posting. With the current code, when will the warning be triggered? If I understand you correctly, you are saying that the new code will allow the balanci...

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 ...

After Al talked with me about this I reached out to Dragonfly to see if they were interested in working together or providing support for this project, in both Windows and MacOS flavors (maybe linu...

Did you go through Tine's troubleshooting tests above? And verify the pin connections at your AMP connector?

Has anyone come up with a reliable solution to this problem? I went out for a week and can't use or trust the capacity battery percentage anymore. super frustrating!
