Special Features of the LiFePO4 Battery

• Integrated Battery Management System (BMS) with numerous protective devices
• Lifespan of up to 2000 charging cycles
• Suitable for uninterruptible power supply (UPS) and emergency power supply
• Low weight – only 2.1 kg
• High performance and safety
• Increased flexibility through parallel connection of up to 4 batteries
• Fast charging with 98% high power density

Price-Performance Ratio

Although the acquisition costs are higher than for AGM or gel batteries, LiFePO4 batteries offer an excellent price-performance ratio. With a lifespan of up to 2000 charging cycles, they significantly surpass the lifespan of the best lead-acid batteries. In addition, the compact design ensures a weight reduction of about 70% compared to conventional batteries.

Integrated BMS for Maximum Safety

The internal battery management system offers automatic protection against overcharging, deep discharge, short circuits, and overheating. These safety features ensure optimal use of the battery and extend its lifespan.

Areas of Application

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

Parallel Connection for Increased Flexibility

The parallel connection of LiFePO4 batteries allows you to easily adjust the capacity and performance of your system. Up to four batteries can be used both in series and in parallel.

Technology of LiFePO4 Batteries

LiFePO4 stands for Lithium Iron Phosphate battery and is a special type of lithium-ion batteries. They offer thousands of charging cycles, leading to a longer lifespan compared to other battery types. In addition, they are safer as they are less susceptible to overheating or thermal instability.

Advantages of LiFePO4 Batteries

• Longer Cycle Life: Up to 20 times longer in cycle and 5 times longer in standby compared to lead-acid batteries
• Low Weight: Up to 40% lighter than comparable lead-acid batteries
• Higher Performance: Double the performance of a lead-acid battery at high discharge
• Low Self-Discharge: Delivers double the performance of a lead-acid battery, even at a high discharge rate
