THE 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. THEY CAN BE USED WITH NEW OR EXISTING 12 V LEAD ACID BATTERIES. JUST STACK THEM IN PARALLEL TO MEET YOUR SPECIFIC SYSTEM SPECS.
Like in all BOS AG Hybrid battery systems the LE300 Lithium Extension 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, the LE300 Lithium Extension Battery takes all surplus energy. This helps to increase the lead acid battery life. 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.
- 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
- 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
The Lithium Extension Battery is specially developed for self-sustaining onboard electricity. Through an extension to the built-in battery, the system offers higher self-sufficiency and longer battery lifetime in caravan camping.
BOATS AND YACHTS
Low temperatures and exceptional weather conditions are special challenges. Due to its resistance under extreme conditions, the BOS Lithium Extension Batteries are very popular with sailors and other watercraft enthusiasts.
SMALL SOLAR SYSTEMS
The Lithium Extension Batteries are used in small sized solar applications around the globe. They can be installed in tiny houses, at water pumps, irrigation systems and parking ticket machines.
TRAFFIC CONTROL SYSTEMS
BOS Lithium Extension Batteries are maintenance-free and have the possibility to extend them with remote monitoring functions. That offers many benefits and highly qualifies them for the usage in traffic control systems.
The network of telecom towers have expanded to far-flung regions worldwide. In many cases, areas have an unreliable grid or no grid supply. Freedom from maintenance, monitoring features and longer battery life are welcome in this scenario.
AND MANY MORE APPLICATIONS
BOS Lithium Extension Batteries can be used wherever a classic lead acid battery needs to be extended. Our customers often inspire us with new ideas and possible application areas.
