EG4-LLv2 + Cerbo GX

[woogerboy21]

Hello! So has anyone had any luck with getting the EG4-LLv2 batteries to talk to the Victron Cerbo GX? I have been running a small system for a short bit now that has been powered by the EG4-Lifepower4 using the lynx shunt for calculating battery capacity and includes the Victron GX (working good for the most part) and decided I would purchase a LLv2 with hopes in getting the BMS to communicate with my system to compare the two batteries and tinker with the settings in hopes to get a more percentage of battery capacity remaining details from the BMS but so far I have had no luck. Given I have very little experience with these product can anyone validate my understanding and configuration.

The EG4-LLv2 is connected via the modified ethernet cable purchased from signature solar from the can port of the battery into the bms-can port of the cerbo-gx. I have configured the can communications to use the victron can option and set the batteries bms to battery 1. However the BMS-can status shows error-active regardless of which port I plug the battery into on the cerbo-gx and I never see any device listed on the vrm portal which leads me to believe they are not communicating.

I attempted to reach out to Signature Solar both when I purchased the battery asking for details on how to configure the devices to communicate along with after being unsuccessful when the product arrived and what I believe is the correct communication and I have yet to hear anything back from them.

Any help would be appreciated.
Thanks.

Same issues here It looks like one person in the comments of this YT video was successful but other than in this official Signature Solar video and commentor in first link I shared it looks like everyone else trying to accomplish this is having a hard time... Not much fun...

I found a solution in another thread! Turns out the labelling of the dip switches is backwards so 1 is 4 and vice versa. Please see here as this worked for me! https://diysolarforum.com/threads/firmware-on-the-new-eg4-ll-v2-batteries.54872/page-2#post-755029
