Offgridtec LifePO4 battery 25.6/100 25.6V 100Ah with BMS and heating mat 2560Wh

The LiFePO4 battery 25.6/100 with heating mat from Offgridtec (MPN 020725) is a state-of-the-art and efficient energy storage solution. With a capacity of 100Ah and a nominal voltage of 25.6V, it ensures both safety and outstanding performance. Thanks to its compact and maintenance-free design, the battery is easy to install and can also be flexibly integrated into individual energy storage systems via parallel connection. Equipped with an integrated battery management system (BMS), the battery is protected against overcharging, deep discharge, short circuits, and overheating. This not only extends the battery life, but also increases safety during operation. The powerful battery impresses with a service life of up to 5000 charging cycles, so you can benefit from a reliable power supply for a long time.

The battery also features an integrated heating mat, which ensures that it works optimally even at low temperatures. This heating mat prevents the cells from freezing and guarantees reliable power output even under extreme climatic conditions. This maximizes the efficiency and service life of the battery, allowing it to be used as an effective energy solution even in cold environments.

The LiFePO4 25.6/100 battery with heating mat at a glance

Advantages of the integrated heating mat

• Protection against damage during charging: LiFePO4 cells must not be charged below 0°C, otherwise lithium plating will occur. This causes permanent damage to the battery and can drastically shorten its service life.
• Maintenance of charging capacity: To enable charging even at cold temperatures, the heating mat warms the cells to a safe temperature.
• Optimizing performance: Cold temperatures reduce the usable capacity and power output of the battery. A heated battery can deliver more energy and operate more efficiently.
• Use in cold environments: Especially in motorhomes, off-grid systems, or electric vehicles, the battery is often exposed to sub-zero temperatures. An integrated heating mat ensures that the battery continues to function even in winter.

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 circuits.By precisely controlling these parameters, the BMS ensures optimal use of the battery and extends its service 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, emergency power) for emergencies

Parallel connection

The parallel connection of our LiFePO4 battery offers you increased flexibility. With the modular design, you can use up to two batteries in series and four in parallel for 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 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.

Advantages of LiFePO4 over conventional 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: Twice the power of a lead-acid battery at high discharge rates.
• Low self-discharge: Delivers twice the power of a lead-acid battery, even at high discharge rates.
• Highly efficient: 92% energy utilization compared to 80% for lead-acid batteries.
• Improved safety features: Integrated BMS protects against overcharging, deep discharge, and short circuits; IP65-rated enclosure.
