1. GENERAL INFORMATION
Thank you for purchasing a high quality, German made product
from BOS Balance of Storage Systems AG. We worked according
to strict engineering standards in order to deliver valuable ener-
gy services for our customers. In case of technical problems or
comments of any kind, please contact the local distributor for
support.
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.
As all BOS AG hybrid battery systems, the LE300 Lithium Exten-
sion 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 and the LE300 takes
all surplus energy. This helps to increase the lead acid battery
life.
The system recognizes the lead acid battery voltage and auto-
matically starts to support the lead acid battery with a maxi-
mum current of 12.5 A per unit. Bigger loads get supplied by the
lead acid and the LE300 in parallel, resulting smaller currents
for the whole system.
