Model:H4B-N16-48V
Product Advantage
Mobile Floor‑standing Design
- Fitted with universal casters at the bottom for easy relocation.
High Safety Performance
- Cell Material: LiFePO4 features excellent thermal stability with a decomposition temperature above 500 °C, resisting combustion and explosion under high‑temperature conditions.
- Cell Structure: Prismatic aluminum‑casing packaging. The cells pass stringent safety tests including over‑charge & over‑discharge, external short‑circuit, extrusion and drop test in compliance with GB/T 36276‑2018.
- BMS Protection: Built‑in voltage and temperature monitoring effectively protects the battery against over‑charge, over‑discharge and over‑temperature. It further enhances safety, improves battery utilization and greatly reduces energy consumption.
Ultra‑long Cycle Life
- Cycle Life: Grade‑A cells adopted, cycle life ≥ 5000 cycles (25 °C, 0.5C, 80% DOD, capacity retention ≥ 80%)
- Low Self‑discharge Rate: ≤3% per month at 25 °C
Wide Operating Temperature Range
- Operating Temperature: Charging: 0~55 °C; Discharging: ‑20~55 °C
- Excellent Capacity Retention at Extreme Temperatures: ≥55% at ‑20 °C, ≥99% at 55 °C
High Energy Efficiency: η ≥ 93% (25 °C, 0.5C)，Eco‑friendly
- Non‑toxic, free of cobalt and nickel heavy metals, compliant with international environmental standards.
