Our LF-ESS261 Battery cluster consists of 5 battery liquid-cooled packs and 1 high-voltage box (integrated power supply unit). Each liquid-cooled pack is made up of 52 314Ah high-performance lithium iron phosphate cells that support 0.5P charging and discharging in series. The high-voltage box contains the battery cluster management unit and protection and control electrical components for the management and protection of the entire battery cluster operating state.
