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 an ultra-modern and efficient energy storage solution. With a capacity of 100Ah and a nominal voltage of 25.6V, it guarantees 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 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 the runtime, but also increases safety during operation. The powerful battery impresses with a service life of up to 5,000 charging cycles, so you can benefit from a reliable power supply for a long time.

The battery also scores points with 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 so that it can also be used as an effective energy solution in cold environments.

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

• Integrated BMS with numerous protective devices
• Integrated heating mat
• Long service life: 5000 cycles
• UPS, emergency power supply
• Higher performance
• superior safety
• Increased flexibility
• up to 4 in parallel connection
• Low self-discharge

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 leads to permanent damage to the battery and can drastically shorten its service life.
• Maintaining chargeability: The heating mat heats the cells to a safe temperature so that they can be charged even in cold temperatures.
• Optimizing performance: Cold reduces the usable capacity and power output of the battery. A heated battery can deliver more energy and work more efficiently.
• Use in cold environments: Especially in motorhomes, off-grid systems or in electric vehicles, the battery is often exposed to sub-zero temperatures. An integrated heating mat ensures that the battery also works in winter.

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 heavy shocks, overcharging or short-circuiting. By precisely controlling these parameters, the BMS ensures optimal use of the battery and extends its 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, 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 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.

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 batteries.
• Low weight: Up to 40% lighter than comparable lead batteries.
• Higher performance: Twice the performance 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; waterproof and dustproof.
