Könner & Söhnen KS LB 24–100 lithium-ion battery

TheKönner & Söhnen KS LB 24-100 is a modern lithium iron phosphate battery designed for reliable operation in energy storage systems, home backup power supplies, off-grid energy solutions and inverter systems. This format is particularly suitable where predictable battery performance, durability, flexible connectivity and clear system status monitoring are essential.

The model is based on LiFePO4 chemistry, which is valued for its high stability, safety and long service life compared to many other types of batteries. For the user, this means more reliable daily operation in domestic or commercial storage systems, where the battery regularly undergoes charge and discharge cycles.

The battery has a nominal voltage of 25.6 V and a capacity of 100 Ah, providing an approximate energy reserve of 2.56 kWh. This makes the KS LB 24-100 a practical solution for small and medium-sized systems where power needs to be supplied to individual circuits, critical appliances, an inverter or part of the domestic load. A depth of discharge of up to 95% allows the available battery capacity to be utilised effectively without unnecessary loss of useful life.

Another strength of the model is the built-in BMS control system. It monitors key battery operating parameters, including voltage, current, temperature and other operating values. This not only helps manage charging and discharging but also enhances the overall reliability of the system. In real-world use, this is particularly important for those who want more stable and predictable battery performance without unnecessary complexity.

The model supports a recommended charging current of 50 A and a maximum charging current of 100 A, as well as a recommended discharging current of 50 A and a maximum discharging current of 100 A. This allows the battery to be used not only in a steady base mode, but also in more dynamic scenarios where the system needs to quickly accept or deliver energy.

RS-485, RS-232 and CAN-bus interfaces are provided for integration into the power system. This allows the battery to be used with compatible inverters and control systems, as well as to configure the BMS communication protocol via the display. A further advantage is the presence of dry contacts, which can be used to transmit system statuses, as well as a port for service configuration and diagnostics.

To monitor the battery’s operation, the housing features an LCD display, a charge level indicator, an alarm indicator and a status indicator. This allows for a quick assessment of the system’s status without the need for additional external monitoring devices. This approach is particularly convenient in day-to-day operation, when it is important to understand at a glance what is happening with the battery.

Support for parallel connection makes the KS LB 24-100 a flexible solution for the future. If, over time, there is a need to increase the system’s capacity, a scalable configuration can be built using several battery modules. For many users, this is convenient as it allows them to start with a single module and later gradually expand the system without having to switch to completely different equipment.

The battery enclosure measures 557×547×227 mm and weighs 27 kg. The model comes with a mounting rack and a set of mounting brackets. The battery is designed to operate at temperatures ranging from 0 °C to 45 °C during charging and from -10 °C to 45 °C during discharging, making it suitable for use in a wide range of indoor environments provided the installation conditions are correct.

The Könner & Söhnen KS LB 24-100 is well suited for those looking for a more compact lithium module for a backup power system or home energy storage, but who do not want to compromise on modern functionality. It is a battery with a good current reserve, clear status indicators, support for communication with an inverter, and the potential for future system expansion.
