Overview
The LEONICS BESS 261 kWh is a liquid-cooled outdoor battery cabinet built on 3.2V/314Ah LFP cells in a 1P260S arrangement across five packs, giving 832 V nominal over a 715 to 923 V operating window. Cell life is rated at 6,000 cycles to 70% end-of-life (25°C, 0.5P). It runs from −30°C to +55°C and up to 4,000 m altitude, derating above 2,000 m. Internal-cycle liquid cooling holds cell temperature more evenly than air cooling, and aerosol fire suppression is fitted.
