You may try the REC Follow again now.  I think they changed it from 500 kps to 250kbps on the last update.   But then you need to change REC BMS to 250 kps, and REC + Zeus needs to be ...

Use of Relays and Opto-Couplers in Master-Slave configuration: Dear community. I have written my questions also to Tine at REC headquarters but he is out of office until at least 1st of June. So ...

@Trond yeah, the battery temp isn't attached to the regulator.  I was hoping it would populate from the REC supplied data.  No such luck....but not the end of the world either as the REC ...

Definetly an step in the right direction.  And I found the same thing, will report til Arco.   BTW, your battery temp shows 0`C.

I've just updated, and setup with REC on can1 at 500K, Zeus as victron follower on can2 @250k.  So far so good, the Zeus(s) see the pertinent battery info from the REC.     but, th...

DVCC seems to work now in V1.25, great. Just make sure NMEA2000-out is enabled in the Cerbo. /Settings/Services/VE.CAN port. If not, DVCC does not work.   I also suspect they changed REC ...

Thank you Rick.  That did the trick!   Bob

ARCO Zeus Firmware 1.25 Update is out. https://arcomarine.com/pages/arco-zeus-bluetooth-alternator-regulator-firmware-updates Now DVCC should work, have not tested it myself yet.  

In recent years it has been confirmed that you generally do not want to use a float charge when charging Lithium Iron Phosphate (LiFePO4) batteries. Unlike lead-acid batteries, which benefit from a...

I can't seem to figure out how to remove the inverter and AC loads icons from my DC only engine alternator system. I'm sure I'm missings some setting somewhere.  Anyone else figure this out w...

The WS-500 2.6.1-January f/w seems to be the ticket  

I'm using 3 as well. Everything seems to be working. Thanks!

Reach out to matthew@dragonflyenergy.com for the latest firmware update. That way, you will get the latest version, which I believe is the January build.     

I've updated to the 2.6.1 January build and can now see field drive on my Cerbo. 

The new series of REC BMS products now incorporate the easy to use Mate N Lok connectors. To insert or remove a pin simply follow these 2 steps bend back the two retaincer clips on the side of ...

Seems like they will release new FW Next week. Found this in an facebook group. Should solve the DVCC not working correctly in current version.          

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
