The LiFePO4 batteries from Offgridtec offer an excellent price-performance ratio despite higher acquisition costs compared to AGM or gel batteries. With a lifespan of up to 2000 charge cycles, they clearly exceed the maximum lifespan of the best lead-acid batteries. The LiFePO4 with a nominal voltage of 12.8V and a nominal capacity of 18Ah impresses with its space savings and a weight of only 2.1 kg, which results in a weight reduction of about 70% compared to conventional batteries. The efficiency during energy extraction is an impressive 92%, which is significantly higher than the 80% of lead-acid batteries. This aspect can be particularly crucial in off-grid systems, especially in off-grid solar or wind power systems.

• Integrated BMS

The LiFePO4 offers automatic protection through the internal battery management system. The lithium iron phosphate chemistry eliminates the risk of explosion or combustion due to strong impacts, overcharging or short circuit.

• Overvoltage protection
• Undervoltage protection
• Overload protection
• Short circuit protection
• Protection of cells against excessively high or low temperatures
• Application areas
• Renewable energy systems, such as photovoltaic & 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

The parallel connection of our LiFePO4 batteries offers you increased flexibility. With the modular design, you can use up to four batteries in series and four in parallel with the 12.8V versions. This allows you to easily adjust the capacity and performance of your system.

• LiFePO4 - Technology

A LiFePO4 battery stands for "lithium iron phosphate battery" and is a type of lithium-ion battery. It is characterized by a specific chemical composition in which lithium iron phosphate is used as the cathode material. The batteries can undergo thousands of charge cycles, resulting in a longer overall lifespan compared to other battery types. They are considered safer than some other lithium-ion batteries because they are less prone to overheating or thermal instability. Furthermore, they offer constant voltage and power over most of their discharge cycle, a high discharge rate and low weight.
