Product description

  • Applications Primary Uses Solar and wind energy storage systems for homes, sheds, and workshops. Uninterruptible Power Supply (UPS) for home backup, hospitals, banks, data centers, small businesses, and offices. Communication base stations and telecommunication systems.
  • Scalability Supports series or parallel connections (up to 16 units) for increased voltage (up to 768V in series) or capacity (up to 1600Ah in parallel).
  • Energy Density Approximately 103 Wh kg, significantly higher than sealed lead-acid (SLA) batteries (30 50 Wh kg). Cycle Life Over 6000 cycles at 80% depth of discharge (DoD), compared to 200 500 cycles for SLA batteries, ensuring a lifespan of 10 15 years under typical usage. Self-Discharge Rate
  • Additional Uses Electric vehicles, electric mobility scooters, and medical equipment. Lighting systems, backup power systems, and other critical infrastructure.
  • Performance Features High Energy Density Prismatic cells maximize energy storage, enabling compact designs for high-capacity applications. Built-in Battery Management System (BMS) Protects against overcharge, over-discharge, over-current, short-circuit, and thermal runaway. Includes active cell balancing for uniform performance and extended lifespan. Monitors voltage, current, temperature, and state of charge (SoC).
  • Connectivity RS485 and CAN Bus Enables integration with inverters, solar charge controllers, and energy management systems for seamless communication.
  • Operating Temperature Discharge -20 C to 60 C, suitable for diverse environments. Charge 0 C to 55 C, with low-temperature charging protection. Storage -10 C to 50 C. Efficiency Up to 98% round-trip efficiency, compared to 80 85% for SLA batteries, maximizing energy utilization. Internal Resistance
  • Charging and Maintenance Charging Voltage 57.6V 58.4V (recommended for LiFePO4-specific chargers). Charging Current Supports up to 50A continuous (0.5C), with recommended charging at 0.2C 0.4C (20A 40A) for optimal lifespan. Charging Time Approximately 2 3 hours to 80% SoC with a 40A charger. Maintenance Minimal; charge every 3 months during standby to prevent deep discharge below 40V, which could cause irreversible damage. Fast Charging Capability Supports rapid charging to 80% SoC in under 2 hours with appropriate chargers.
