All-around performer—flexible with lithium technology from Offgridtec

Despite higher upfront costs compared to AGM or gel batteries, Offgridtec’s LiFePO4 batteries offer excellent value for money. With a service life of up to 2,000 charge cycles, they generally far exceed the maximum service life of even the best lead-acid batteries. The LiFePO4 battery, with a nominal voltage of 12.8 V and a nominal capacity of 30 Ah, stands out for its space-saving design and a weight of just 3.34 kg—a weight reduction of about 70% compared to conventional batteries. The energy extraction efficiency is an impressive 92%, which is considerably higher than the 80% achieved by lead-acid batteries. This aspect can be of crucial importance, particularly in off-grid systems—especially in off-grid solar or wind power installations.

Integrated BMS

The LiFePO4 battery provides automatic protection through its internal battery management system. The lithium iron phosphate chemistry eliminates the risk of explosion or fire due to severe impacts, overcharging, or short circuits. By precisely controlling these parameters, the BMS ensures optimal battery utilization 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

Applications

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

Parallel Connection

Connecting our LiFePO4 batteries in parallel gives you greater flexibility. Thanks to the modular design, you can use up to four 12.8V batteries in series and four in parallel. This allows you to easily adjust the capacity and power 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. These batteries can withstand thousands of charge 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. Furthermore, they offer a constant voltage and power output throughout most of their discharge cycle, a high discharge rate, and a lightweight design.
