@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...

Delighted to finally bring our WS500 alive under full Victron Lynx Smart BMS /Cerbo GX DVCC Whitespace control.  The 2 year old Cerbo firmware needed updating along with the long awaited 2.5.2...

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!

@Chris Hi Chris. I've planned to use Mahle MG1 48V 100A in my RV, just want to know the connectivity diagram from the WS500 to Mahle MG1. I've summarized the question need your input as following, ...

@Bill this is from Al Thomason, Chief Engineer on the WS500. Upon seeing the forum thread that I sent to him, he replied... ---- Fun!   We never added an external USB socket for two reason...

Ah, I see the time sisnce posting is shown in gray on th4 header bar.

Thanks Rick.  Good idea. Would it be feasible to add a datestamp to Fora postes?  This is a rapidly develooping area and  it would be valuable to be able to calibrate "Just released...

@Adam thanks!

There is not an easy way of coping them, so here are some screenshots:

@Adam can u share your bms settings pls?

@panagiotis So far: nothing. The issue stopped happening. I suspect the cells must be more closely balanced, now.

This will be handy for many customers. Thanks for taking the time to document this hack. :) To maintain IP67 a grommet might do the trick.  I always kept this cheap little kit onboard. https...
