BOS - Model LE300 - Lithium Hybrid System

The lithium extension battery LE300 can simply be connected to the plus and minus pole of the existing 12 V lead-acid battery. Unlike switching to pure lithium batteries, no charging technology needs to be changed. True plug & play makes it easier and safer to expand lithium capacity to experience self-sufficiency and travel freedom anew.

Smart Battery Systems are engineered and manufactured in Germany, with a passion for quality in every detail. The LE300 can compete with the highest safety standards. Consequently, it holds a wide range of certifications, including the E1 mark for secure use in motor vehicles. The LiFeP04 high-performance lithium cells are rated among the safest in the industry and are fully tested by engineers before installation. Protected by a range of safety mechanisms such as overcurrent, overvoltage, short circuit, deep discharge, and wrong polarity protection.

The integrated high-performance BOS battery management system takes care of protecting and balancing the lithium cells while monitoring the lead-acid battery. The patented hybrid technology uses advanced algorithms to optimize the use of capacity and charging cycles of both batteries in the long term.

In normal lead-acid systems, batteries often fail within one to three years due to limited cycle life and sulphation caused by continuous operation without a full charge. The intelligent distribution of loads and capacity in the LE300 solves these problems and extends the life of all batteries to up to 10 years.
