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

The LiFePO4 battery 25.6/100 with heating pad 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, maintenance-free design, the battery is easy to install and can also be flexibly integrated into individual energy storage systems through 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 service life but also increases safety during operation. The powerful battery impresses with a lifespan of up to 5000 charge cycles, allowing you to benefit from a reliable power supply for years to come.

The battery also features an integrated heating pad that ensures optimal performance even at low temperatures. This heating pad 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, making it an effective energy solution even in cold environments.

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

Advantages of the integrated heating pad

• Protection against charging damage: LiFePO4 cells must not be charged below 0 °C, otherwise lithium plating occurs. This causes permanent damage to the battery and can drastically shorten its lifespan.
• Maintaining charging capability: To enable charging even at low temperatures, the heating pad warms the cells to a safe temperature.
• Optimized performance: Cold reduces usable capacity and power output. 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 pad ensures the battery works even in winter.

Integrated BMS

The LiFePO4 provides automatic protection through the internal battery management system. The lithium iron phosphate chemistry eliminates the risk of explosion or combustion due to severe impacts, overcharging or short circuits. By precisely controlling these parameters, the BMS ensures optimal battery use 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 & solar installations
• Vehicles such as motorhomes, caravans and campers
• Marine applications such as fishing and electric boats
• Uninterruptible power supply (UPS, emergency power) 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 adapt 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. These 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. They also offer constant voltage and performance over 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 cyclic use 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.
• 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% with lead-acid batteries.
• Enhanced safety features: Integrated BMS protects against overcharging, deep discharge, and short circuits; enclosure rated IP65
