Mix and match Batteries

[Emeryj32]

Hello All

I have two Eg4 6000xps and 30 kWh of battery. The batteries are eg4 life power 5.12 48v 100 ah and u have six of them. I want to add more battery power and was wondering if I can add different batteries to this system?
Possibly eg4 life power 200ah or the eg4 new 14.3kwh indoor battery. Or even maybe another namebrand. I’d like to continue to have communications so I know what is going on with the batteries. Any advice would be greatly appreciated. Thank you and have a great day.

As long as they are the same chemistry and nominal voltage, you can absolutely mix brands and capacities.
But as far as communication, that's only possible with compatible BMS protocols.
I can't make any recommendations on communication, as I have no interest in it. So I don't follow the information around it.
