Offgridtec LifePo4 battery 12/100 12.8V 100Ah with BMS and heating mat 1280Wh

The LiFePO4 battery 12/100 with heating pad from Offgridtec (MPN 020715) is a state-of-the-art and efficient energy storage solution. With a capacity of 100 Ah and a nominal voltage of 12.8 V, it ensures both safety and outstanding performance. Thanks to its compact, maintenance-free design, the battery is easy to install and, through parallel connection, can also be integrated flexibly into customized energy storage systems. Equipped with an integrated Battery Management System (BMS), the battery is protected against overcharge, deep discharge, short circuits and overheating. This not only extends runtime but also increases safety during operation. The powerful battery impresses with a service life of up to 5000 charge cycles, so you can benefit from reliable power supply for a long time.

The battery also features an integrated heating pad that ensures optimal operation 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.

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 allow 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 that the battery works 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 battery offers you increased flexibility. With the modular design, you can use up to four batteries in series and four in parallel with the 12.8 V 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 overcharge, deep discharge and short circuits; enclosure rated IP65
