@Ben what do you mean by "The switch is NC model, keep that in mind."? The ABMS mini switch I refer to has to positions and appears to be a simple on-off switch that connect power to the BMS. ...

Update. I still experience randon disconnections. I have tried different firmware configurations and gotten the latest from Tine. Currently as running as follows: The signal is otherwise strong. T...

We have many users with 4P4S EVE packs running the REC Active BMS without any need to add balancers.  Unless you are mating cells with different capacities the Active BMS will balance your pac...

Hi all, I'm building and testing a 3P4S battery using EVE314Ah cells. The battery's size is pushing the limits of the ABMS's balancing capabilities. I'm considering integrating a Heltec 5A active...

@Hans to have a battery protect, as low voltage discontactor, you need to know, IF only one cell comes low, the Battery Protect will not "see" this. If your cells are perfectly balance also at the...

If you do any bench testing, measurments on the field wire, always have a load connected to the blue wire.  A resistor from 1k would be enough.   On the bag from cable harness is a warn...

Hi, I believe you have to log on to the routers ip adress ( that the wifi module are connected up to) plus the port number :4799. But then I believe you need to setup a DNS server adress as the ro...

A few weeks ago, I received 1 REC Master 9M and 3 of the new REC2Q Slave units for a 12V 3-parallel bank installation directly from REC in Slovenia. Experiences like this highlight the importance o...

I have repaired a couple of V1.0 WS500 an the field driver is U5 (IRS21867). On these units, the field has been missing, not fully on like in your case. But I would start by meassuring U5, p...

Yes. V1.28 seems to fix a lot of the previous bugs. I can confirm DVCC now works. 

@Rick This is where I wish I still had easy access to an electronics rework bench, as I can more or less see what's going on with the Field Driver circuit.  We'll probably reach out soon.

Hans, I have heard of this happening on older W500s and I believe they hardened some of the circuitry on the newer versions. We dont like to see this happen so if you'd like to upgrade to the new...

@Rick Yeah, looks like I'll have to pick up the wifi module.  In this case, it's for the rest of the DC system on my boat (lighting, VHF radio, AIS transponder, instrumentation, etc...). Righ...

Hi Everyone, I'm wondering if I've managed to cook the field output on my Wakespeed in the worst possible way. I have a P-Type alternator, and the P-Type harness. At my alternator, the red Alt + i...

Hey Hans, glad you're making progress.  In the latest f/w version there is no longer a separate 2 relay version.  Using the "Tasks" page in the Wifi module you can set it to drop out on l...

So after an email from Tine, I went and checked my system. Turns out for the past 3 years I've had my contactor leads flip-flopped. RE1 was controlling the contactor on the charging side of the wor...

@Matt Nice!! Thanks for letting us know

Hi All, I've been happily running my ABMS for several years now, in an all up Victron+REC+Wakespeed configuration. During that time, I've only updated the firmware on my CerboGX, leaving the REC a...

Woohoo!!!   I just updated my regulators today and they're actually following DVCC!  Happy day!

Loading the files directly onto the SD card did the job - thanks.

As Trond mentioned, there are 2 files in the dowload zip file, and both must be uploaded. If that isnt the issue, then you can try the workaround and manually add them the SC card on the Wifi modu...

Did you unzip the folder first?    https://rec-bms-na.com/product-manuals/#7-12-wpfd-rec-wi-fi-module  

I'm trying to install the latest firmware on my WiFi module following the video instructions and instead of the messages shown I get "Update file not found". Hardware 1.2, current SW 1.1. I tried...

my daughter's MB Sprinter van has the non pro WS500 and I want to see the alternator output displayed on her Victron display. Can you help?

On the Victron Community Venus OS beta thread, if you are testing these then it is worth keeping up with the development. As V3.60 is now released, the full change log is available on Victron Prof...

@Tine Andrejasic  Tine, are you able to include this variable in the next firmware update? Rick

Can we get this added? VenusOS supports it and it would be nice to have. 

Ok, I'm glad that someone else is seeing the same thing. Where did you see the text "Add Battery charge request info"? In some release notes or elsewhere?

DVCC does work. Under /System, have you enabled "Support Victron DVCC = ON"?  

These datas are sent by the "REC-BMS Q Series BMS". Seems to be an new feature in Venus release-candidate v3.60~73. The description is so far only this "Add Battery charge request info". So far ...

@Peter That's my understanding as well, and my set up. 

  Just noticed that in the House Batt (REC-BMS Q Series BMS) Parameters page, "Reqests Charing always shows "No" even when the WS-500 is charging the battery and the volatge is lower. Is this...

I thought that you needed the shunt on the alternator output and to have set the alternator maxium amps value aswell for DVCC to function correctly.

Yes, it is indeed to high. Try setting the Charged Voltage to 13.9V.

WS500 does indeed support DVCC.  Just make sure your WS500 has newest FW and DVCC support is enabled in the settings in WS500.

Hi All I have a 1120Ah LifePO4 battery, a REC BMS, a Cerbo GX, a Multiplus II and a WS500. I am getting significant different SOC readings between the REC BMS and the Victron BMV. I think the cha...

Hello all I have a 1120Ah LiFePO4 battery with a REC BMS, a Multiplus II, a Cerbo GX and a WS500. The Wakespeed is driving a 180A water cooled alternator. A great setup and I am very happy with ...

They fixed one more thing on V1.25. When Alternator current is below 1A, it now sends data to the Cerbo as 0A. Before it would show +10W all day, every day, messing up the consumption calculation...

You can not remove this, Victron systems are nearly all built aroubd ac/dc conversion. Perhaps one day it will be customisable.

Victron recently confirmed that this was waiting for updated WS500 firmware when I reported it.
