Application And Environmental Adaptability:
1. Wide input voltage, avoids frequent switching to battery power because of large power grid voltage, reduce
battery failure probability, adapt to the power environment in poor areas.
2. The environment which require higher IP level, we use heat exchanger to effectively reduce the temperature
of box inside and improve IP protection level .
■ Long-term storage of the battery needs to be placed in a dry, clean, dark, and well-ventilated environment.
The suitable storage temperature range is -20~35℃.
■ Batteries must be stored and transported in a state close to 50% SOC.
