250-350W
2-3 kg
25-45 km
350-500W
3-4 kg
40-80 km
500-750W
4-5 kg
50-100 km
750-1000W
5-6 kg
Battery Capacity & Range
Battery capacity (measured in Ah - Ampere-hours) directly affects your e-bike's range:
- Rider weight and cargo
- Terrain and hills
- Speed and assist level
- Wind resistance
- Tire pressure
- Battery age and condition
Choosing the Right Battery
Consider these factors when choosing your e-bike battery:
Battery Maintenance Tips
Proper maintenance extends your battery's lifespan and maintains performance:
- Store at 40-60% charge when not in use
- Keep in cool, dry place (10-25°C)
- Avoid direct sunlight and extreme temperatures
- Charge to 100% before long-term storage
- Clean terminals monthly with baking soda solution
- Rinse with clean water and dry thoroughly
- Check for corrosion or damage
- Keep battery case clean and dry
- Check voltage regularly
- Monitor charging time
- Watch for unusual heat or swelling
- Test range periodically
Charging Best Practices
Always use the manufacturer-recommended charger for your battery
Don't leave battery charging overnight or for extended periods
Charge in temperatures between 10-30°C for optimal performance
It's better to charge to 80-90% for daily use than 100%
Wait 10-15 minutes after riding before charging
