Our batteries undergo 10 professional safety tests to ensure stable performance even in extreme conditions:
Low Pressure Test: No explosion, fire, or leakage (reliable in abnormal pressure scenarios).
Short-Circuit Test: No explosion or fire during short circuits (guaranteeing power safety).
Overcharge Test: No explosion or fire under overcharge (protecting against charging system failures).
Over-Discharge Test: No explosion, fire, or leakage during over-discharge (adapting to deep discharge needs).
Thermal Test: No explosion or fire in high-temperature environments (stable in hot climates).
Nail Penetration Test: No explosion or fire when pierced by sharp objects (resistant to accidental damage).
Crush Test: No explosion or fire under extrusion (withstanding external pressure).
Drop Test: No explosion, fire, or leakage in case of accidental drops (safe during transportation and installation).
Seawater Immersion Test: No explosion or fire when immersed in seawater (suitable for marine and humid environments).
Thermal Cycle Test: No explosion, fire, or leakage during temperature cycle changes (adapting to day-night or seasonal temperature fluctuations).
（2）Reliable Quality Control
Each battery undergoes strict pre-shipment quality checks using professional equipment, verifying key indicators such as voltage and internal resistance. This ensures the products you receive are free of defects and ready for immediate use.
（3）Versatile Applications
The battery is widely suitable for:
Solar energy storage systems (matching rooftop photovoltaics to store excess power).
Outdoor power supplies (powering camping equipment, portable appliances).
Power tools (supporting continuous operation of drills, grinders, etc.).
Backup power for communication base stations (ensuring uninterrupted signal during outages).
Its stable power output guarantees long-lasting device operation, performing excellently in home energy storage, outdoor work, and emergency backup scenarios.
