Product Description

Rechargeable Lithium Ion 48V 50ah External Battery LiFePO4 Battery 19 Inch Rack

Product introduction:
EverExceed solar LiFePO4 battery system is mainly used for the energy store battery of Photovoltaic system; its
advance  intelligent  lithium  battery  management technology  to  ensure  the  intelligent  automatic management. With "Energy transfer" balanced patented technology, EverExceed Fe lithium provide high efficiency balanced and prolong system operate life.





Features:

• High cycle life and deep cycle: For infrastructure powered from high cycle life and deep cycle cost
  primary energy sources (e.g. diesel generators powered in off‐grid or unreliable grid locations and
  anywhere energy storage systems are used to reduce CO2emissions).
• Battery management: The battery system adopts special BMS high performance battery manage-
  ment module which is featured with voltage, current and temperature protection and a preferable
  communication between the battery system and the host.
• Intelligent monitoring: The monitoring unit checks the charging and discharging current, voltage
  and monomer battery surface temperature and ambient temperature automatically.
• Lightweight, high energy density standby power: The EP-48xx series batteries, due to their ex-
  cellent properties, are the optimal energy storage solution where limited space and or weight are im-
  portant factors.
• Excellent expansion capability: Configuration flexibility, support parallel connection expansion.
