With recent upgrades of the Venus/Cerbo firmware to 3.3X and REC-BMS 2Q Firmware 1.5 the REC 2Q BMS will now work properly on the Victron VE. CAN port instead of using the BMS.CAN port. This will allow for both the WS500 and REC to reside on this network concurrently while taking advantage of Victrons DVCC control
Here is a quick video to help you through the steps.
PLEASE NOTE: At 3 minutes into the video you need to power off/power back on the BMS to reset the CANS speed.
