FT02 Dual Battery System — Second Battery Set
Important Purchase Note:
If your FT02 has a 48V battery, please order the 48V version.
If your FT02 has a 52V battery, please order the 52V version.
Estimated Maximum Range (Realistic Reference)
Based on official FT02 data and real user feedback, the range with the original 22.5Ah battery is roughly as follows:
|
Riding Mode |
Original Battery Range |
Dual Battery Estimated Max Range |
|
Pure Electric (No Pedaling) |
70–80 km |
160–190 km |
|
Pedal Assist Mode |
90–100 km |
210–260 km |
|
Eco Low-Speed Assist (~20-25km/h) |
100–120 km |
230–280 km |
Most optimistic maximum range: 250–280 km (flat roads, low wind resistance, light load, and very economical riding).
Real-World Factors Affecting Range
- Higher speed = faster battery drain: Riding at 40-45 km/h will reduce range by 30-40%.
- Terrain: Hills and slopes will significantly decrease the range.
- Load: Carrying passengers or heavy cargo can reduce range by 15-25%.
- Temperature: Cold weather (below 5°C) can cause over 20% power loss.
- Dual Battery Setup: Make sure the voltage is the same (both 48V), and check if the controller and BMS can handle the increased capacity. Some FT02 models may require wiring modifications to support a second battery properly.
