You set the parameter in the SCO string to zero to use the dipswitches.  Here is a page snip of what it looks like in the WS500 tool we include with the WS500  

I\'m bit confused about the dip switch vs configuration software.  Do the dip switches set the basic parameters then the configuration software fine tunes those parameters OR does one override the ...

I have just installed a REC BMS with Victron GX, 2 x solar regs and Victron Multi 24/3000/70-50 and 2 x WS500 regulators (currnetly only trying one) The WS 500 is showing on the Can bus but does...

Hi Rick I tried to modify SCA / Derate

Hey Chris, What variable in the WS500 are you trying to change with the tool?  I will test it and confirm. And unfortunately when I last looked I was not able to find a MAC compatible version...

Thank you for the information. I have tried to change the values via the WS500 Config tool. There seems to be a bug in the software. It is not possible to change these values to 0.25 there. I\'m ...

Does anyone have a wiring diagram for the ABMS and the REC BSLRD  and the Blue Sea 7713? thanks  

 If I am not mistaken the Venus is based on the BeagleBone, not sure what the Cerbo version uses. Cerbo GX uses Venus OS - the very same version that\'s on the Rpi. :)

I\'ve just found the Victron product. Its not surprise  no-one buys them - £523!!! Good grief. They do the community a solid by open sourcing VenusOS, but then price connectivity like that when USB...

You will need a CANBus hat for your RPI or an MCP2515 board powered and connected to the GPIO on the RPI. I set one up years ago, but when you look at the Cerbo with all of its additional IO, re...

Hi, has anyone set up their REC-BMS ABMS with communication with a Raspberry PI instead of the Cerbo GX ?  At the moment I can\'t see how to  get VE.Can comms to the Raspberry PI. thanks in a...

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...

Here some technical details of the 48V alternator

My tests in the workshop were about 10v-12v for the field

Should be 56v to charge the LiFePo4 battery controlled by a rec q bms

How much is the output voltage?

Hi guys, I have rebuilt one of the two engines (Volvo Penta D2-30) on our catamaran and changed the previous 12V/115a alternator to a Mahle MG1 48V/100A. The internal charge controller has been r...

I\'ve seen a system 3s, 4p, no bridging between strings, and it\'s in balance after 4 years. Good cells are amazing Only way to do SOC control I know is using switched outputs on BMV712 to trig...

As I read the ABYC requirements there seems to be a need for an Alarm before disconnect, and possibly seperate charge and load bus control. It already seems to meet the temperature and charge moni...

Thanks for the suggestion, Damian.  The original SD card wouldn’t format so I swapped to a new, formatted card and got the same result.  I did use a 64 GB SD card and wonder if it is too large for ...

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 Trond Arvid Røsvik on August 7, 2022, 2:55 am I tried this, and Cerbo sees the WS500 and ABMS, but the WS500 would not see the ABMS. Are you sure your WS500 is in Sync Mode?  ...

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. ...

OK - I have upgraded my WS500 to 2.5.0 & my Cerbo GX to 2.90-14 I cant see any Wakespeed info ? I assume it should show up in the Device list. The Bus is working fine between GX, ABMS &am...

Thanks Rick, somehow missed the mention of the configuration mode. I have the crossover cable and the terminators and will install the new shunt to just measure the alt current!

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...

Damian, Trond makes a very good point here.  3.65 V is the maximum \"working\" voltage, but the maximum safe voltage is usually quite a bit higher.  You do not want to perform a hard trip unless...

All,   Wakespeed WS500 ver 2.5.0 was released Monday -- but it might take a bit to get posted to the website.  For all\'s convenience, I have attached the .dfu file and the companion con...
