@bamsefar1 Yes, you can connect 4×B300 + 2×B300S to the AC500 system. The B300S includes a built-in heating module, which automatically preheats the battery in low temperatures, enabling charging in environments as cold as -20°C .

I would like to ask a question very similar. I have (4) B300S and (2) B300 batteries can I use all of them with my AC500 and get the full 18,400 Wh?
