Advantages of LiFePO4 Technology

Compared to conventional AGM or Gel batteries, LiFePO4 batteries offer excellent value for money. Their lifespan of up to 1500 charging cycles generally significantly surpasses the best lead-acid batteries. In addition, they are space-saving and reduce weight by about 70 % compared to traditional batteries. With an efficiency of 92 % in energy extraction, they are particularly efficient, which is of great importance for off-grid solar or wind power systems.

Integrated BMS

The integrated Battery Management System ensures automatic protection of the battery. The lithium iron phosphate chemistry minimizes the risk of explosions or fires due to overcharging, short circuits, or strong impacts. This ensures optimal use of the battery and extends its lifespan.

BMS Protection Functions

• Overvoltage protection
• Undervoltage protection
• Overload protection
• Short circuit protection
• Temperature protection for the cells

Areas of Application

• Renewable energy systems such as photovoltaic & solar systems
• Vehicles, including motorhomes, caravans, and campers
• Marine applications such as fishing and electric boats
• Uninterruptible power supply (UPS) for emergencies

Parallel Connection

The ability to connect our LiFePO4 batteries in parallel offers additional flexibility. With the modular design, you can use up to four batteries in series and four in parallel with the 12.8V versions to individually adjust the capacity and performance of your system.
