We produce battery packs for boats such as hybrid yachts, electric yachts, electric speedboats (also high performance).

Our lithium battery packs are sealed with IP67 certification to ensure maximum safety even in the marine environment. It is possible to install air or liquid cooling systems to guarantee excellent performance even at extreme temperatures (-20 , 50 ºC).

The IP67 certification, which we hold, is an international protection index that is assigned to electronic devices and other products to indicate their level of resistance to dust and water. The acronym "IP" stands for "Ingress Protection" and the number 67 represents the assessment of the protection of the device based on two factors:

  • The first number (6) indicates protection against dust. In this case, the 6 indicates that the device is completely protected against dust and other solid particles.
  • The second number (7) indicates protection against water. In this case, the 7 indicates that the device can be immersed in water up to 1 meter deep for a maximum of 30 minutes without suffering damage.

In addition, in the marine sector, the specifications of the cooling or heating system of lithium batteries depend on the size of the vessel and the capacity of the batteries used. The cooling or heating systems we design are designed to keep the batteries at the optimum operating temperature, prevent overheating and any degradation of battery performance.
For example, a large electric yacht could have a liquid cooling system for batteries, in which the liquid is pumped through channels inside the battery to absorb the heat produced during charging and discharging the battery. While a small electric yacht could have a simpler air cooling system, in which air is sucked in from the outside and circulated through the battery to keep the temperature constant.

The cooling and heating system we design is created to ensure the safety of the crew and passengers. We make sure to create the right one for your boat by choosing between two types of batteries: LTO and LFP.
Technology details
Lithium titanate (LTO) lithium batteries

Lithium titanate (LTO) lithium batteries are a type of lithium-ion battery that uses lithium titanate as an anode. Here are some of the technical specifications of LTO batteries:

  • Rated voltage: 2.4 V
  • Specific energy density: about 30-60 Wh/kg
  • Specific power density: about 1,000-2,000 W/kg
  • Life cycles: up to 20,000 charge/discharge cycles at a discharge depth of 80
  • Charging time: about 10-20 minutes for a full charge, depending on battery capacity and charging current
  • Operating temperature: -30 C to +55 C
  • Safety: LTO batteries are considered to be among the safest lithium-ion batteries as they are less prone to overheating, explosions and fires than other lithium-ion batteries.

LTO batteries are often used in applications where long life, fast charging and increased safety are required. Technical specifications can vary depending on the specific application for which they are designed. We make them together with the customer according to his needs.

Lithium iron phosphate batteries (lifepo4) are a lithium-ion battery technology that uses electrolyte composed of lithium salts dissolved in organic solvents. Below are some common technical specifications for LFP lithium batteries:

  • Energy density: 90-120 Wh/kg
  • Rated voltage: 3.2 V
  • Lifetime: up to 2,000-5,000 charge/discharge cycles depending on operating conditions and manufacturer specifications
  • Self-discharge rate: 2-3% per month at 20 C
  • Charging temperature: 0-45 ºC
  • Discharge Temperature: -20-60 χ C
  • Safety: less prone to combustion than other lithium batteries
  • Environmental Sustainability: do not contain toxic heavy metals such as lead or cadmium and are maintenance-free

The technical specifications of LFP lithium batteries may vary depending on the specific application for which they are designed. We make them together with the customer according to his needs.
