They are available in capacities of 12.8 V or 25.6 V. 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 V\u003csup\u003e1\u003c\/sup\u003e) and 48 V\u003csup\u003e1\u003c\/sup\u003e) system. \u003c\/p\u003e\u003cp\u003eA single LFP cell has a nominal voltage of 3.2 V.
