E-Bike Battery Requirements
Electric bicycles require compact, lightweight batteries that deliver sufficient range for daily commuting while maintaining safety and longevity. The 48V 21Ah configuration provides 1.01kWh of energy storage, enabling 40-70km range depending on rider weight, terrain, and assist level.
Urban commuting involves frequent stops, starts, and varying speeds. Batteries must deliver high discharge rates for acceleration while providing consistent voltage throughout the ride. LiFePO4 chemistry offers the safety and cycle life that daily commuters depend on.
48V 21Ah Performance
Nominal voltage of 51.2V (16 cells in series) with 21Ah capacity. Maximum continuous discharge of 40A supports 750W-1,000W motors. Peak discharge of 80A handles hill climbing and rapid acceleration. Built-in BMS provides comprehensive protection.
The compact form factor fits standard e-bike battery mounts. Weight of approximately 5kg maintains bike handling. Quick-release mounting enables easy removal for charging. IP65 rating protects against rain and road spray.
Commuter Benefits
Daily commuters benefit from 2,000+ cycle life, providing 5-7 years of service. Charging time of 4-6 hours from standard outlets suits overnight charging. No memory effect enables partial charging without capacity loss.
