They can be connected in series, parallel and series\/parallel so that a battery bank can be built for system voltages of 12 V, 24 V or 48 V. The maximum number of batteries in one system is 20, which results in a maximum energy storage of 84 kWh in a 12 V system and up to 102 kWh in a 24 V¹ and 48 V¹ system. A single LFP cell has a nominal voltage of 3.2 V. A 12.8 V battery consists of 4 cells connected in series and a 25.6 V battery consists of 8 cells connected in series. \u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eWhy lithium-Iron-phosphate? \u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eRugged\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eA lead-acid battery will fail prematurely due to sulfation:\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003e • If it operates in deficit mode during long periods of time (i.e. if the battery is rarely, or never at all, fully charged).\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003e • If it is left partially charged or worse, fully discharged (yacht or mobile home during wintertime). \u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003eA LFP battery:\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003e• Does not need to be fully charged.
