TRANSPOWER Lithium Phosphate Battery (TLi48-20) 48V 20Ah Black

• Lithium Iron Phosphate (LiFePO4) Battery
  • Voltage: 48 Volts
  • Capacity: 20 Ampere-hours
• Suitable for backup power systems, telecommunication systems, and energy storage applications such as
  • solar PV systems, wind power systems, and CATV power generation systems at 48 volts. It cannot be connected in series to increase voltage.
• Can be connected in parallel to increase capacity up to 15 sets, resulting in a total capacity of 300 Ampere-hours at 48 volts.
• Can deliver high current for a short period, approximately 20 Amperes per hour, which is twice as good as lead-acid batteries.
• Can be connected to a computer to monitor and check the status of individual battery cells through the RS232 interface.
• Can communicate with inverters and other devices through the RS485 interface.
• Lithium Iron Phosphate batteries are three times lighter than regular lead-acid batteries.
• Can operate for more than 2,000 cycles at 80% depth of discharge and performs well in Thailand's environmental conditions.
