Connect to Victron Controller

First of when only DIP 6 is facing upwards, it's recognized as a "Pylontech battery" and the charge controller will not see any battery details like cell voltage, temps - so avoid using this mode.

Cerbo GX

Buy a cable from Victron or build it yourself: Cerbo GX: VE.Can to CAN-bus BMS cables manual. DIP 5 & DIP 6 up, conenct the special CAT cabel and enjoy the battery details.

Venus OS

Victron Venus OS provides the Battery Can Bus drivers but not the Hardware port. So just get a Waveshare RS485 CAN Pi HAT and connect GND, CAN-L (Low) to Pin 5 and CAN-H (High) to Pin 4.

There are certainly other options for non-Raspberry Pis Venus OS setups. So we do not need BMS support in dbus-serialbattery / issue support BMS DR-JC03.

Battery Stack Setup

  1. Connect the master pack with DIP 5 and 6 facing upwards, as indicated in the Victron connection instructions.
  2. The pack will be recognized as an "LFP battery" and you can view the voltage of the highest and lowest cell under the "Details" section.
  3. You can also see the number of packs online and if there's a pack preventing charging/discharging.
