Re: They are using Fluence Gridstack
They are identified as:
Battery Supplier / Module
CATL / LFP-280LC
These are LiFePO4 batteries from CATL, their 280Ah cells in a liquid cooled frame, as I already suspected would be used.
Lower cost per usable kWh than lead-acid.
Cycle life of 8000 when charging fully and discharging to below 5%.
If they cycle between 20% and 80% cycle life will increase dramatically.
