⚙️ All-Weather Operational & Maintenance Guidelines

To guarantee that your YOSE POWER core yields maximum lifecycle retention across the coming years, adhere to these simple charging principles:

• Environmental Charging Thresholds: Always recharge the unit in a well-ventilated, dry indoor location within the recommended 0°C to 45°C window.

• Extreme Weather Discharge Ranges: Built to withstand harsh seasonal commutes, delivering dependable current across an all-weather -20°C to 55°C discharging window.

• Prevent Deep Over-Discharge: While the internal BMS safely guards your cells against flatlining, plugging in your e-bike before the display bar reaches absolute zero prevents early chemical degradation.

• Long-Term Storage Voltage: If storing your Vivi e-bike for the off-season, leave the battery isolated in a cool space at roughly 40% to 60% capacity rather than completely full or empty.
