Product details

The VICTRON Lithium NG batteries (Next Generation) are state-of-the-art lithium iron phosphate batteries (LiFePO4) that have been developed for demanding energy applications such as off-grid systems, camping, boats or industrial installations. The batteries can be flexibly connected in series or parallel to configure battery banks with system voltages of 12, 24 or 48 V. Up to 50 batteries can be connected together in 12 V or 24 V battery banks, allowing a maximum capacity of 192 kWh (12 V) or 384 kWh (24 V) to be realised.

Integrated shunt and external BMS
The Lithium NG batteries have an integrated shunt that transmits the battery data to an external BMS. The external BMS is not included in the scope of delivery and must be ordered separately!
All parameters are automatically managed by the BMS, enabling precise recording of cell voltages, temperatures and states of charge in real time. In addition, the number of batteries in parallel, series and series/parallel connection is automatically recognised. The data can be analysed and controlled via the VictronConnect app or Victron GX systems.

Low self-discharge rate
The NG batteries are characterised by a high level of safety and a long service life. Depending on use, several thousand charging cycles can be achieved. In addition, the self-discharge rate of the Next Generation series has been improved (approx. 2% per month), which means that a service life of up to 10 years can be achieved.

Robust design
The lithium NG batteries are also ideally suited for use in the harsh maritime conditions on board. They have an IP protection class of IP65 and are equipped with mounting brackets, which enables easy installation and prevents the batteries from slipping or tipping over.

LiFePO4 batteries on boats and yachts - properties, special features and use
This FAQ page contains answers to the most frequently asked questions about LiFePOS4 batteries and how they are used on boats and yachts. Our SVB technical experts tell you what you need to know about installation, maintenance and safety requirements, battery management system (BMS), charging and discharging as well as monitoring of LiFePO4 batteries.

Lithium iron phosphate batteries on boats and yachts - properties, special features and use
The lithium iron phosphate battery (LiFePO4 battery) or LFP battery, is currently the best in the battery sector. A basic distinction is made between conventional lithium-ion batteries and the newer generation of batteries, lithium iron phosphate batteries. The terms lithium-ion battery and lithium iron phosphate battery are often used interchangeably in everyday language. However, this generalisation is not correct when comparing the two types of battery directly and with regard to their chemical and technical structure. Both battery types have decisive differences. In this guide, we explain what these are in detail, which battery type has which advantages and many other details, especially about lithium iron phosphate batteries.
