Lithium batteries have certainly become one of the preferred technologies for applications in the electric mobility sector. They have the ability to store far more energy than any other battery and do not lose charge capacity, reliably delivering energy. And finally they are undoubtedly much longer lasting than any other type of battery. In short, batteries are a key point and Torqeedo, which has been a pioneer in the development of lithium batteries since 2005, knows this very well.
Lately, the company has decided to improve its product offer by announcing a new battery option. We are talking about the Deep Blue Battery 80, that features a lithium iron phosphate (LFP) chemical composition and supplies 80 kWh of storage energy. Practically double compared to the previous version of batteries of this series. The presentation was held at the Electric & Hybrid Marine World Expo in Amsterdam: let’s find out more in the following details!
The characteristics of the Deep Blue Battery 80
The latest generation of LFP (lithium iron phosphate) batteries ensures a volumetric energy density by leveraging the cell-to-pack structure. This means enhancing the accumulation power without requiring excessive volume. Added to this are maximum durability, reliability, and total safety with a ten-year capacity warranty for recreational and commercial use. But let’s see specifically what are the strengths of this new Torqeedo battery:
- Made with raw materials to avoid high costs or ethical-environmental issues related to the extraction of critical metals
- Long life cycle and high temperature resistance
- Constant power and a continuous flat voltage curve
“This new battery marks one important step in our new strategy to make Torqeedo even more customer-centric by providing optimized products for specific market segments,” commented Fabian Bez, Torqeedo’s CEO.

As mentioned above, the cell-to-pack structure of this new battery is an advanced approach to how the battery is assembled. It consists of the union between the individual battery cells that are integrated directly without the need for intermediate modules or components. This results in less volume and a battery that is much more compact and perfect for installation on different types of boats.
“In the past, lithium iron phosphate batteries just took up too much room but they have come a long way over the past couple of years,” Bez explained .
The use of the battery on boats
Thanks to its high volumetric energy density (278 Wh/L) this battery is also ideal for larger vessels with a higher weight, such as cruise yachts or commercial vessels themselves.
Also, let’s consider that a passenger’s ferry emits the same pollution as about 40 diesel buses, which is why it is advisable to think of a suitable solution to obtain its electrification. A real priority that Torqeedo did not want to ignore.
“LFP batteries have excellent longevity and safety and are made with abundant raw materials which avoids the high cost, ethical and environmental concerns, and sourcing instability of critical metals in today’s fast-moving markets,” concluded the CEO.
After all, it’s precisely the LFP batteries that play a key role in the transport sector: in fact, they are also used in electric cars, in particular by the absolute leader in the sector which is Tesla. The time had therefore come to make the leap in quality and propose this solution also for the navigation sector.
