Frequently asked questions
Capacity & Range:
To understand how far a battery will take you, the total energy capacity — often expressed in Watt-hours (Wh) — matters more than just voltage. Wh is roughly calculated as Volts × Amp-hours (Ah).
Higher Wh → more range. But actual range depends heavily on rider weight, terrain, how aggressively you draw power (acceleration vs cruising), and the efficiency of motor/controller.
Before you begin researching, you want to narrow down your choices by asking yourself a few simple questions.
1. What’s your riding style?
Mostly casual rides, commuting, errands, flats or gentle hills → 48 V or 52 V is enough.
Mixed terrain, hills, occasional cargo, want reliable performance + decent speed → 52 V is probably ideal.
Heavy loads (cargo, passengers), steep/mountain terrain, frequent throttle/power demand, or you want “e-moto” level performance → 72 V (but only if your system is built for it).
2. What motor / controller are you using (or planning)?
Must match battery voltage. A 48 V motor/controller requires 48 V. A 72 V system requires all components rated for 72 V.
Using a high-power controller or high-current draw motor → higher voltage can reduce required current, stressing wiring less.
3. What’s more important: range or power (or both)?
For balanced power + range: 52 V with decent Ah → good compromise.
For maximum range (and modest power): a high-Ah 48 V or 52 V pack works well.
For maximum power (acceleration, heavy-duty), maybe shorter range — 72 V or high-current 52 V / 48 V packs may be better.
4. How heavy / complex a system are you willing to operate and maintain?
48 V systems tend to be simpler, lighter, cheaper, easier to maintain.
72 V systems require better wiring, BMS, quality components, and good mechanical build quality — more demanding but powerful.
5. What are my local regulations?
High-voltage / high-power e-bikes (especially 72 V builds) may be treated differently under local laws — sometimes as electric motorcycles instead of standard e-bikes.
Look at the battery’s Watt-hours (Wh) — that’s roughly Voltage × Amp-hours. Higher Wh means more energy, which generally means longer range (all else equal).
But actual range depends on many variables: rider weight, terrain, speed, how much throttle/assist is used, and how efficient your motor/controller system is.
