My EG4 LifePower4 batteries ID addresses have been set, and they are connected to each other with standard Ethernet patch cables per the RS485 ports. The two EG4 LifePower4 BMS's communicate to each other. The Cerbo GX cannot communicate with the EG4 LifePower4 batteries. I don't know if the EG4 batteries can communicate with Basic Broadcast CANBUS.Thanks. Do you have the batteries connected to the gerbo otherwise then? Using can or rs485?I’ve seen on a few forums, folks asking if these batteries “work/communicate” with the cerbo via the can/rs port. Because it seems they’re made to work with growatt and there is little to no information about them being used with victron products. You are the first post I’ve seen using these batteries and victron, is why I ask. Wasn’t sure what if any communication you’re able to get from the batteries to victron. Thanks for the update, sounds like a nice setup
The Cerbo GX is designed as a central connection for all of Victron Energy's different device's using multiple interfaces/protocols. and allows a simple interface to monitor them, and do some of the configuration. The EG4 batteries have their own BMS. Victron Energy can manage some batteries without BMS's (like their own batteries), and a list of other batteries that that have been tested and are known to work. See link below:

The EG4's work great with Victron Energy, and are configured as LiFePO4 batteries with "Other BMS". All charging parameters are set exactly to Signature Solar's specifications with the Victron Energy Config App. The Victron Energy SmartShunt is used to monitor all aspects of the batteries. The Cerbo GX is used to set that.
If you are interested in the individual cells and balancing of the EG4's, you have to use the BMS Monitor software for PC, available from Signature Solar, and is delivered with the batteries. I think this software is to look at the Signature Solar batteries only, and not meant to change parameters. Use at your own risk.
I have ordered two Jakiper batteries, and it they ever show up, the will also have their address ID set as batteries 3 and 4, then connected per Ethernet patch cables to my EG4's. They have the same BMS's and should all communcate with each other.
I know this was long winded, but I hope this gives you the information you are looking for. I hope I didn't bore anyone.
