Building upon the success of our Lithium Smart Series, the NG (Next Generation) series incorporates significant enhancements. Victron Energy Lithium NG batteries are Lithium Iron Phosphate (LiFePO4 or LFP) batteries available with a nominal voltage of 12.8 V, 25.6 V and 51.2 V in various capacities. 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 50, which results in a maximum energy storage of 192 kWh in a 12 V system and up to 384 kWh in a 24 V and 48 V system.
