The 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 also be connected in series, parallel and series/parallel so that a battery bank can be built for system voltages of 12V, 24 V or 48 V.
PLEASE NOTE: These batteries allow for virtually unlimited charge and discharge currents; however, they must be connected in conjunction with a Victron Battery Management System (BMS) appropriate to the design and scale of the system.
Contact Overkill to discuss the BMS design best suited to your needs.
