Multitalented – flexible with lithium technology from Offgridtec
Despite their higher purchase price compared to AGM or gel batteries, Offgridtec's LiFePO4 batteries offer excellent value for money. With a service life of up to 4000 charging cycles, they generally significantly exceed the maximum service life of the best lead-acid batteries. The LiFePO4 with a nominal voltage of 12.8V and a nominal capacity of 304Ah impresses with its space-saving design and a weight of only 30.3 kg, which represents a weight reduction of around 70% compared to conventional batteries. The energy extraction efficiency is an impressive 92%, which is significantly higher than the 80% achieved by lead-acid batteries. This aspect can be particularly important in off-grid systems, especially in grid-independent solar or wind power systems.
Integrated BMS
LiFePO4 offers automatic protection through its internal battery management system. The lithium iron phosphate chemistry eliminates the risk of explosion or combustion due to strong shocks, overcharging, or short circuitsby precisely controlling these parameters, the BMS ensures optimal battery usage and extends battery life.
- overvoltage protection
- Undervoltage protection
- overload protection
- Short circuit protection
- Protection of cells against excessive or insufficient temperatures
Areas of application
- Renewable energy systems, such as photovoltaic and solar systems
- Vehicles, such as motorhomes, caravans, and campers
- Marine applications, such as fishing boats 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 for 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 charging cycles, resulting in a longer overall service life 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. They also offer consistent voltage and power throughout most of their discharge cycle, a high discharge rate, and low weight.
