All-rounder - flexible with lithium technology from Offgridtec

The LiFePO4 batteries from Offgridtec offer an excellent price-performance ratio despite higher acquisition costs compared to AGM or gel batteries. With a service life of up to 1500 charging cycles, they generally significantly exceed the maximum service life of the best lead-acid batteries. The LiFePO4 with a nominal voltage of 25.6V and a nominal capacity of 50Ah impresses with its space-saving design and a weight of just 11.2 kg, which represents a weight reduction of around 70 % compared to conventional batteries. The energy extraction efficiency is an impressive 92 %, which is considerably higher than the 80 % of lead-acid batteries. This aspect can be particularly important for off-grid systems, especially for 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 shocks, overcharging or short-circuiting. By precisely controlling these parameters, the BMS ensures optimal use of the battery and extends the battery's service life.

• overvoltage protection
• Undervoltage protection
• overload protection
• Short-circuit protection
• Protection of the cells against excessively high or low temperatures

Areas of application

• 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 two batteries in series and four in parallel with the 25.6V 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 that uses lithium iron phosphate as the cathode material. The batteries can go through thousands of charge cycles, resulting in a longer overall lifespan compared to other types of batteries. They are considered safer than some other lithium-ion batteries as they are less prone to overheating or thermal instability. They also offer constant voltage and power throughout most of their discharge cycle, a high discharge rate and low weight.
