I had an customer try this, still shows 0% in V2.60-72. Strange.. 

Still no news from Arco on that "next week" firmware update.   Have you been able to test the Zeus now Rick?   

Yes, correct.  Use protocoll 2 or 3, depending on your preference.  Personally I have used 3, with same setup as you.

I have heard others report the same, with 2.6.0 and Venusv OS v3.55. Perhaps try to update cerbo to Release-candidate V3.60-7X, it has an "fix" for this:        

Based upon this from the manual, I think that I should use option "3."

On a LiFePO4 battery system that incorporates a Cerbo GX, Wakespeed WS-500 and the REC-BMS which Alternate CAN / BMS protocol are people using?  

- Cerbo GX running latest sw - WS-500 running f/w 2.6.0  - WS-500 charging at 153 amps, but field drive reporting shows "0%" - Does anyone know if this is a WS-500 or Cerbo GX issue? - I h...

Turned out to be component U5 (IRS21867), Gate Driver. $2 fix, now it works again. 

If  you have a Cerbo gx,  the Venus OS large and associated node-red functionality reportedly allow to set the charging parameter such that you could charge 5 times to 80% and the eight t...

sorry, I havent seen this one

I have seen that a few times.  I recall Bill talking about beefing up the circuit in the next version.  If there is not any PCB damage and you have a surface mount soldering kit you may b...

Hello. Have anyone had the field output of WS500 fail? Spesific the V1.0 board. Of so, what was the fix?    Field output at 100% gives an steady 11V out unloaded (13.2V in), but when ...

Hi, it seems like i have the same problem. With the 2.6.0 the Data comes correct, but with the 2.6.1 from Wakespeed Support, i need for the REC-BMS, i get no Data on N2k. Can you send me the firmwa...

My system consists of WS500-PRO, REC-ABMS, Victron Cerbo GX. In the Victron menu area for the WS500 the "State" is generally "External Control" but often goes to "Off" for no apparent reason? Alt...

Currently there is not a single command way to do this but you would just need to adjust your CHAR parameter down to about 3.5V. That being said, we do not recommend it for long term use as it wil...

i would like to adjust the bms to charge only to 90 or 95 percent instead of full charge what settings would i change?   thanks   tom

The 2Q includes 2 internal fuses, one for power and the second for the Opto relay output. Remove all 8 M10 screws from the front and back covers open case and remove the flush mount screw using...

The question in this thread does not match the thread title...   What is the correct value to use for LiFePO4 cells???    @Ben recommneds 1.0, but I believe that I've seen othe...

I used Rick's cheat sheet along with recommendations from Ben.  

@Rick Admin , As I am considering my options and reviewing the 2Q details, I also need to ensure that they are compatiable with my WakeSpeed WS-500 regulators and will work seemlessly with the Cer...

Hi Rick,  Thanks so much for your quick response! I thought I’d post this in the forum here, just in case others have similar questions.  I’ll definitely take a look at the ...

Thanks for the update.  We are hoping to be able to provide some testing feedback ourselves in the next week.

Just got this feedback from Arco: "Ok, found the issue on DVCC.  We are fixing it, and it will be available in the next week or so.  The comms issue (unplugging the network cable) has be...

Hey Bill, If your serial# on your Q BMS is 4000+ it has the additional memory and can be upgraded to 2.9x.  We just need the serial# For your Master/Slave, it too can be upgraded but we will...

With Sync Disabled you should see these data. And this works just fine.. I also have REC BMS, but using it with volt sense is fine until Arco improves the SW.  I was also an "beta tester" fo...

@Trond I tried the other day to get the Zeus to follow DVCC using a smart shunt as the battery monitor....no joy.  I brought this up to Andre at Arco that following a BMS was not participating...

@Richard Thanks! I am reviewing the video. Great suggestion.

Hello all,  Any news on a SW update for the Q-BMS devices? I have a 9M managing two Q-BMS 4P8S house batteries. I also have a single Q-BMS for my propulsion engine start battery.  I am ...

Tested in system with Victron Smart BMS NG and still can not get DVCC to work. Not sure what I am doing wrong.   Also, in V1.24 there is no timeout if Zeus looses contact with BMS. The las...

@Stefano  Email with 1.6.2 F/W sent.  Also check for any nearby AC power lines.  Induced AC noise can be a contributing factor Is your wifi module in a natural faraday cage?...

@Ben de Groot thank you. I have brifly tried to have the REC Wifi module to join the boat AP, but unsucessfully. I admit, that have not tried hard enough. But I will get the 1.6.2 from OGM and see...

@Stefano I have many wifi's running on 1.6.2,  very stable. 1.6.2 was an improvement compare to older versions  I didn't have tried the 1.6.3 version. Maybe try 1.6.2 or that works bet...

Hi Ben, Thank you for looking into this. It is the latest, the REC-WiFi-module-firmware-update-1.6.3-March-28-2024 firmware, which I installed on first connection along with all available firmwar...

@Stefano I use different switches as well. The switch is NC model, keep that in mind.

Which firmware is installed in the WiFi unit?

Hello, For context, I am installing an ABMS-PreCharge-WiFi with LFP 3P4S EVE314 cells on a boat. The WiFi functioned correctly during bench testing in the shop. However, once installed on the boa...

@Bill C.  seem the most sensible think to do. Thanks for replying.

for what it's worth, I replaced my switch with a bigger one that is mounted in a watertight box and labeled the hell out of it.

In a marine environment anything is possible with the humid salt laden air.  I would remove and inspect the harness and connector pins

@Rick could the bad connection be in the plug/socket arrangement in the bottom of the BMS?????
