The short answer: higher voltage (60V) lets the motor deliver more power without higher current, which means higher top speed and better sustained hill climbing. Lower voltage (48V) is lighter, cheaper and perfectly adequate for flat commutes. Battery capacity is measured in watt-hours (Wh), which is voltage multiplied by amp-hours — this is the number that actually predicts range.
Why voltage matters
Motor power equals voltage times current (P = V x I). At the same current, a 60V battery can feed a motor 25% more power than a 48V battery. Higher voltage also reduces current draw for the same power, which lowers heat buildup in the controller and wiring.

| Model | Voltage | Capacity | Energy (Wh) | Top speed | Range |
|---|---|---|---|---|---|
| Veloflow E3 / E3S | 48V | 13Ah | 624 Wh | 28 MPH | 35-45 km |
| Veloflow E3 Pro | 48V | 15.6Ah | 749 Wh | 31 MPH | 40-50 km |
| Veloflow E5 Pro | 48V | 18.2Ah | 874 Wh | 38 MPH | 50-60 km |
| Veloflow E5 Ultra | 52V | 20.8Ah | 1,082 Wh | 44 MPH | 65-75 km |
| Veloflow E7 Pro | 60V | 20.8Ah | 1,248 Wh | 44 MPH | 75 km |
| Veloflow E7 Ultra | 60V | 23.4Ah | 1,404 Wh | 44 MPH | 75-85 km |
48V: the commuter standard
48V systems are the most common in electric scooters. They are lightweight, inexpensive, and parts are widely available. For flat-city commuting at 25-30 km/h, a 48V 13Ah pack (624 Wh) is enough for a 35-45 km ride. Charging takes about 6-7 hours.
52V: the middle ground
52V packs are common on performance scooters because they lift top speed without a big weight penalty. Veloflow's E5 Ultra uses a 52V 20.8Ah pack (1,082 Wh) for a 65-75 km range at up to 44 MPH.
60V: high power delivery
60V systems feed the strongest motors. The E7 Pro (60V 20.8Ah, 1,248 Wh) and E7 Ultra (60V 23.4Ah, 1,404 Wh) use them to sustain dual 1200W and dual 1500W motors. Expect 75-85 km of range and a 44 MPH top speed. The trade-offs: heavier battery, longer charging time (7-8 hours) and a higher price.
How to estimate real range
As a rule of thumb, an adult rider on flat ground consumes roughly 12-15 Wh per kilometer at 25 km/h, and 20-25 Wh per kilometer at 40 km/h. Divide your battery's watt-hours by your consumption rate to estimate range. A 1,404 Wh pack at 20 Wh/km gives about 70 km — close to Veloflow's rated 75-85 km.
