1. Product description
1.1 General Information
The LIONTRON® LX48-50 is a modular LiFePO4 battery for highest demands. Due to its long
cycle life, the battery is ideally suited as a storage battery for photovoltaic systems, inverters or a
stand-alone power supply.
Highest safety and maximum service life are guaranteed because of high-quality LiFePO4 cells
and latest BMS-Technology, even with regular deep discharges. The battery enables fast efficient
charging and very high discharge current.
By simply hook-up of several battery modules, an increase of capacity can easily be done, even at
a later date.
1.2 Product features
▪High-End storage battery
especially for use of Photovoltaic systems.
▪Integrated (BMS) Batterie-Management-System
with adaptive cell balancing. Protection against short circuit, overcharge and deep discharge.
▪Secure Lithium-Technology (LiFePO4)
Lithium-Iron-Phosphat. No gas, explosion or fire hazard. Absolutely maintenance-free. No
„memory-effect“.
▪High cycle life
maximum cycle life with more than 6000 cycles even with regular deep discharges.
▪High discharge current and efficient charging
Continuous discharge power more than 3kW per battery module. Charging efficiency up to
99%.
▪Low self-discharge
only about 3% per month for storage / non-use.
▪Easy expandability
Through modular construction and possible mounting in 19“ racks.
▪Easy operation
Only DIP switches for addressing when using multiple battery modules.
