The LE300 Smart Battery System is a lithium expansion to increase the capacity and performance of the lead battery, as well as the efficiency and service life of the overall system.

The lithium expansion battery takes over most charging cycles while the lead battery works as a cheap backup storage. The lead battery is loaded with a higher priority, with the lithium battery taking over the surplus energy. When unloading, the lithium battery is primarily unloaded. As a result, the lifespan of the lead battery is significantly extended. The LE300 recognizes the voltage of the lead battery and automatically begins to support the lead battery with a maximum current thickness of 12.5 A. Larger loads are supplied in parallel by the lead battery and the lithium battery, which contains both batteries with less electricity.

All advantages at a glance

Plug & Play> Easy Connection of two cables
Flexible adaptation of the capacity by simply putting together individual modules.
Use of the existing lead loader possible.
Performance optimization of the battery system by loading priority of the lead battery and preferred unloading of the lithium battery
The performance of the lithium battery and the cost advantage of the lead battery are combined.
Slim and light design with variable fastening options.
Integrated heating system.

4 different variants available:
