   - The 5V output on the Venus GX can be used to power, for example, a USB hub. Note that its output is not current limited or otherwise protected, and it shares the internal power supply in the Venus GX: overdrawing from it will result in shutdown(s) of the Venus GX. It is recommended to install a fuse for prevention.   - The 5V output on the Venus GX can be used to power, for example, a USB hub.

 +  - Though the Maxi GX, MultiPlus-II GX and EasySolar-II GX all have a dual set of RJ-45 sockets labelled VE.Can, this port is actually a dedicated BMS-Can port. It can only be used to connected to managed batteries like BYD, Pylontoch and others, at 500kbps. The hardware does not meet the requirements for a VE.Can port; and thus it is not possible to use to port to connect Victron products such as the SmartSolar VE.Can MPPT product range. Note that current version of Venus OS firmware still allows to select the VE.Can function and other baudrates. The result will be unreliable, and future firmware versions will lock the feature to BMS-Can only and 500kbps.
 +  - A BMS-Can port is a port dedicated to be used for connecting managed batteries, like BYD, Pylontech, Freedomwon and others, only. It is not possible to connect Victron VE.Can products to that port. To connect such managed battery, use our [special cables](https://www.victronenergy.com/cables/ve-can-to-can-bus-bms), and see documentation [here](https://www.victronenergy.com/live/battery_compatibility:start). Connect the side labelled 'VE.Can' into the BMS-Can/VE.Can port on the GX Device. And connect the other side to the battery. The baudrate of a BMS-Can port is fixed to 500kbps.
