Yunfan Factory Direct 25.2V 58.8Ah High Safety Lithium Storage Battery Wide Temperature Range Anti-Puncture Shock Resistant Off-Grid Equipment Power Battery OEM ODM

This 25.2V 58.8Ah special energy storage lithium battery is engineered for outdoor and extreme environment off-grid power equipment. It overcomes common limitations of ordinary storage batteries such as narrow temperature tolerance, weak structural stability, and insufficient safety performance. Equipped with multi-layer safety cell structure and intelligent full-protection BMS, it supports stable 50A continuous discharge and 70A instant pulse output, with built-in RS485 communication port for real-time data interaction with control systems.

• Ultra-Wide Temperature Adaptive Performance: Stable charging from -20℃ to 45℃ and consistent discharge output within -40℃~60℃, suitable for all-season extreme environments
• High Standard Safety Cell Structure: Anti-puncture internal cell design and reinforced shock-resistant casing reduce potential risks during transportation and outdoor operation
• Strong Continuous & Instant Pulse Discharge Capacity: 50A stable standard discharge and 70A instant peak current meet high-power startup demands
• Standard RS485 Bidirectional Communication: Real-time transmission of voltage, residual capacity and temperature data for centralized monitoring
• Low Internal Impedance Design: Internal impedance ≤50mΩ reduces heat accumulation and extends service life
• Integrated Intelligent Multi-Layer BMS Protection: Built-in overcharge, over-discharge, overcurrent and overheating protection modules

• All-Season Outdoor Field Monitoring Equipment: -40℃~60℃ ultra-wide temperature working window guarantees uninterrupted power supply for year-round outdoor monitoring devices
• Mobile Off-Grid Remote Power Equipment: Reinforced anti-shock casing and anti-puncture cell structure improves durability for frequently moved field equipment
• Industrial Portable Testing & Detection Instruments: 70A instant pulse discharge capacity meets instantaneous power demand of industrial testing equipment startup
• Unattended Remote Off-Grid Energy Storage Systems: Standard RS485 communication port enables two-way data linkage with remote monitoring hosts for automatic equipment management
