including Al in this last request for clarification @al-thomason

I have not ever seen this one before so I can not help but if you reach out to tine@rec-bms.com he might have some insight. @tine

A \"Cycle\" is determined as having been completed by the BMS when the cell pack goes from relatively full condition to a relatively empty condition, and is used to assist in monitoring the health ...

Quote from Jamie Reece on February 1, 2022, 12:34 pm Thank you. I understand parallel vs. series . I\'m asking about the specific settings in the \"Battery Pack Data\" section of the software wher...

Hi @rick_tech_support, Seems the BMS throws the internal error every time it has been balancing for a while. I\'m correlating the data and it appears the error is thrown 10 minutes after bala...

Eric,   For your install I would refer you to the Victron Lynx website - it has a few very extensive examples of how to install the Lynx BMS with dual alternators and the WS500. In or...

One thing I forgot to mention... I need to derate (using WS500) both of my alternators from 100A to 75A because of the small belts/pulleys that I have on my engines. Should I go instead with the...

  Hi @rick_tech_support, @al-thomason, I\'m planning to install this weekend my new Balmar alternators with two WS500 on my boat (with Victron Smart Lithium battery bank, VE.Bus BMS and ...

My ABMS system has been in service for a month and I\'m delighted at how well it is has integrated with the Victron system I installed at the same time.  Another pleasant surprise was the Victron i...

I don\'t think I updated the BMS. It\'s currently running v2.7 and I purchased it from you around a year ago. I don\'t think the temperature spike was spurious, since it clearly happened after b...

The only way your password can change is if you were to update your BMS firmware with the wrong BMS firmware bin file.  Your wifi firmware update will not affect it.  If you have done an update, ch...

I loaded the logs and happened to catch an error: I assume > 50ºC is bad? The cabinet around it is not that warm, clearly.

Yeah, I get that, it\'s connected properly and reading all data. I see the request go to the module with the password in it, but it fails. Can that password be changed? i.e. did I change it with...

you need to be connected to the BMS in order to log in, not just your WiFi module.  If you are getting your battery parameters on the Home page you are connected. Password is your serial number ...

This is pretty strange, it tells me password doesn\'t match no matter what I do. Have you seen that before? Should I try restarting the WiFi module?

Perfect, thanks. For some reason I can\'t seem to get it to unlock. I\'ll try a different browser…

On the Firmware page log in using your serial number without the first hyphen.  Like 1Q-1234  CAPS on. scroll down the Firmwar page to the Manual Commands section and enter your command. This...

What is the simplest way to send it a command? I have the WiFi module and the BMS is connected to a Cerbo GX.

My first choice would be something like an Orion B2B. And yes, a single alt failure should not affect the output of the other unit. And one other item that Ben reminded me of, in this config bo...

I think redundancy is pretty important once I’ve tossed the Genset…. So maybe a spare WS500?? I believe the dual alternators would by default be operating as a fault-tolerant scenario… as nothing ...

I recall talking with Al about this about 5 years ago and he was saying that it would be great for this application but most dual alternator setups seemed to comprise leaving the factory alt. on th...

This error can have several causes and some of them are coded to self heal.  There may be a bit of info in the error  log that might help but it might need to be reset first. Try using the ERRO ...

Good Day, I got a single, seemingly random, \"Warning Internal Failure\" from the Q BMS. No alarms are visible, now. Should I be concerned? A.

Hello Rick, About dual alternators on a single engine.  I\'m wondering why Al said this:  \"To be honest, we do not see this install very often.\" I have a single engine monohull (w/ Yammar 4...

Yes, it is in alpha/beta testing now!  

Yes, something like this should do the trick. https://www.amazon.com/StarTech-com-Black-Straight-Through-Serial/dp/B00A6GIV9K/ref=sr_1_3?keywords=db9%2Brs232&qid=1652709077&sr=8-3&th=1

It looks like your dip switch or set to small alt. parameter is enabled. I never had much luck getting the number of poles from the datasheets, so I would just leave it set to the default and ad...

Seems like we are very close now..!

you have a couple of options to configure: there is a free android application that you can use on your phone and connect to the WS500 USB directly using what is called an OTG cable or adapter...

I\'m looking to place my LCD more than 6M away from the BMS.  Can I simply use an RS232 extension cable with DB9 connector to do so?

I unfortunately took a break from the project and haven\'t gotten to figuring that part out yet.

I am curious how you dealt with this situation; were you able to disable Multiplus charging on Com failure?  CRITICAL!

Rick - I purchased a WS500 and REC Active BMS in February,  in this thread, you said: The beauty of CANBus is that many manufacturers can share data but the downside is having to use differ...

Just got around to looking at this connector in person (as I was about to pin the mating connector).  The info wakespeed provided was only partially correct:  The Field/Stator connector is a DT06-2...

I knew I was missing something.  Thanks so much for the prompt response - especially on a holiday weekend!  

All of your secondary variables can be set and viewed using the \"Manual Input\" function on the \"Firmware\" page of the WiFi Module. You will need to log in first before this option appears ne...

I\'ve purchased the WIFI module thinking I would be able to fully configure my system using that interface.  I find it only allows me to edit a limited number of parameters.  I\'m not able to confi...

this is useful information

I was looking at the field line graph in the software without the engines running and both were at 75% but when I adjusted the small alternator value they decreased. Any thought on good starting...
