BOS LE300 Lithium Extension Battery is a fully scalable solution to enhance performance and add capacity to lead acid batteries in solar and any other kind of energy storage systems. It comes in a robust housing and can be used with new or existing 12 V lead acid batteries. The intelligent technology allows multiple LE modules to be stacked in parallel to meet your specific system specs.

Like in all BOS AG Hybrid battery systems, the lithium battery takes most of the charging cycles while the lead acid battery provides inexpensive backup capacity. The lead acid battery is charged with higher priority, while the lithium battery takes all surplus energy. This process helps to increase the lead acid battery lifetime.

The integrated battery management system recognizes the lead acid battery voltage and automatically starts to support the lead acid battery. Lithium battery powers most of the loads, while lead acid is kept at floating point most of the time. However, bigger loads are supported by lead acid and the lithium battery simultaneously, which results smaller currents for each battery, reducing the strain on both the batteries.

Applications include: Lead-Acid batteries back up, caravan/automobiles, sailing, solar home systems, teleocommunication towers.

  • Flexible capacities by simply connecting several packs 
  • State of the art LiFePO4 batteries 
  • Retrofitting & extension of already installed systems without change in wiring or other components 
  • No additional controller needed, simply connect directly to the lead acid batteries 
  • Lead acid battery is charged with higher priority, lithium battery is discharged first The system recognizes the lead acid battery voltage and automatically starts to support the lead acid battery with a maximum current of 12.5 A per unit. Bigger loads get supplied by the lead acid and the lithium battery in parallel, resulting in smaller currents for each battery. 
  • Lithium performance and lead acid cost advantages are combined 
  • Plug & Play > simply connect two cables 
  • Robust housing with variable fixing possibilities 
  • Integrated heating for low temperature charging   
  • Made in Germany
