This is an A-BMS 12V installation? Anyhow, it your 100% sure the senswires are correct then it sounds like your BMS is broken.
You will probably find that is more easy convert the alternator insted. From negative regulated alternator over to positive.
Ben is right, you will not get the VE.bus BMS V2 to sync to the WS500, as it does not send CAN bus data like REC BMS does. You will have to setup the WS500 with regular Lifepo4 charge profile. ...
What value did you set the \"Min T-Charge\" to in the BMS? By default its -15`C.

Yes, something is definitely limiting Field to 31%.. Could be the PBF, Pull back Factor, is this set to 0? If not, then you have to setup everything so the WS500 reads the correct R...
You can connect the sense wires to the two large M10 terminals. I have done this in my own system, no problems.
Yes, V2.8 comes with an updated manual. If you have an A-BMS, send me your e-mail some how, and I will send the files to you. Don\'t want to post my e-mail here in case I get flooded with req...
Hi AL. Yes I am running WS500 V2.5 and Venus OS V2.90 already. That hardcoded overvoltage used to be 16.2V in 12V system. I know, as I have an client with 3.7V nominal cells, he ...
This is the settings I am using. (4S 1000AH Winston). This gives \"Bulk/Absorption\" 14.2V and Float 13,5V, same as Victron recommendations. \"cmin\":2.8,\"cmax\":3.8,\"tmax\":55,\"...
Just want to add there is an huge improvement in the A-BMS V2.8 on how the charging is regulated. No more jumping up and down of the current in last phase of charging. Just be aware...
Yes, there is an V2.8 out now. But I don\'t think you will find it online. Contact your local REC dealer.
Its probably caused by the BMS, but we cant tell by looking at that graph. I believe you can get the \"max charge current\" graph from the BMS up there as well. A-BMS FW 2.8 and WS500 FW2.5 ...
You could get the REC WIFI module. Would be cool if you could download and upload config over VRM for Wakespeed. Should be easy to integrate, but I doubt that will happen. I know...
I guess the biggest drawback is the WS500 will go from Bulk to float the second the battery hits 14.2V. How much effect this will have i guess also depends on the battery and alternator size. ...
You can connect an Masterbus shunt to an WS500 if you want. Shunt is between negative input and output in the Mastervolt shunt. Just connecto the WS500 shunt terminals to these two posts and...
Understood. I thought maybe you used the Mastershunt as an shunt for the WS500.
I belive the Mastervolt Mastershunt 500 is 300A/50mv. You would think its 500A/50mv, but its not.
Yes, probably your cable is meant for connection to Victron, but we dont know that. You can see that by looking at the RJ45 connector. Is there cables on PIN 7 and 8? Or is there cables on...
Configuration and even more monitoring thru the Victron VRM system would be optimal. Download and upload of config file. But I guess that would be a bit optimistic.
Its all in the manual. https://www.rec-bms.com/wp-content/uploads/2022/02/UserManual_ABMS_Victron_Wakespeed.pdf The command to set the canbus speed to 250kbps is: CANF 250 After that, y...
Also make sure you use the correct CAN bus cable. Of you have connected the REC BMS directly to the WS500 you will ned an special CAN bus Cable. Usually the REC BMS comes with an cable made f...
I guess you could partually solve this letting the WS500 Charge lamp output drive an small relay. Then you would have to use an \"Normal Closed\" output on the relay. This should give you the...
The Android App has an function for updating FW. So far i have NOT been able to get this to work. Is there some trick to it?
In Norway we have the same issue. Works when choosing US Windows Language. But I have seen other installations where it did not even work with US language. Hope this will be fixed in next ...
See page 14+15 in the manual. I would prefere option #2. 1) Connect the ALT+ (Red) wire to a 12v source With this approach, the field power source is supplier f...
I use currently the VE-CAN port only, set to 250 kbps. A-BMS->Cerbo->WS500->NMEA2000 to the boat. This works perfect. An bonus with this is sending Engine RPM data and A-BMS status ...
Quote from Matthew Parsons on August 6, 2022, 11:47 pm I have a question - my ws500 is hooked up to my cerbo, I can see it in the device list. Its controlled by the REC BMS using DVCC and seems...

In my experience all units have to be on 250 Kbps. At 500 Kbps the Cerbo will not \"see\" the WS500. Meaning you also have to use VE-CAN ports, as BMS CAN port is 500 Kbps only. ...
Damian: Having an low \"start balance\" will only make the charging prosess longer. As Rick says, recomended working voltage is up to 3.65V Even if you do reach 3.8V for a few seconds or e...

Just change CHIS til some lower value, problem solved?
Hi Ben. Yes I do agree, balance in the cells is important, and will play an large role in how long the process will be in charging the cells. But my 1000AH Winston bank is perfectly balanced....
My experience is that this was much better in Wakespeed V2.4.3. Then in V2.5_Beta it got worse again. Confirmend by going back to V2.4.3 so I belive Wakespeed are on to something.. ...
Does anyone know the difference between HW 1.0, 1,2 and 2.0?
Start with 1%, then 2% etc until you get an reading. The minimum field% will even be active during the 30 sec default startup sequence of the WS500. I would not bother about RPM readings on I...
There is an mode for this called \"Tach mode\", search it up in the manual. I have set minimum field to 3% and this works perfect. But be careful as this could potentially overcharge the batt...
