I have 2 Basengreen batteries, in parallel, connected to my Multiplus II. The batteries’ BMS are interconnected via RS485 as suggested by the make. Now, should I see this set as a single battery or as 2 batteries on the VRM/Remote console?

Usually when batteries are comms connected in one bank, they appear as one device as they are one bank. What should change is the CCL and DCL- if they are communicating properly you should see multiples of the specs of one. (E.g. 50A DCL h one battery, for 2 batteris DCL will be 100A)

I guess I thought my batteries were communicating properly to the Multiplus but it is not. What happens if I connect a battery that does not have a BMS? How can I know that Multiplus is getting data, in a way it understand, from the BMS?

Thank you, but the problem is solved. Please look at this thread: [image] Missing battery information DIY Check cerbo settings power down and then reboot and see if it shows up hope that helps, mine are pylontech [IMG_5669] [IMG_5668] [IMG_5670]
