Electric motorcycle battery:should my bike run 48V, 60V or 72V?

E-motorcycle battery selection answers three questions: how big is the motor, how far does the bike go in a day, and what does it normally carry. Fix those three and the voltage platform and capacity step are determined. At an equal 3000W at the axle, a 48V bus carries about 62.5A, 60V about 48.0A and 72V about 40.5A — higher voltage means lower current and less harness heating (copper loss down 55.5%), but it also raises the voltage rating, insulation and controller cost of the whole vehicle. This page gives the decision table, the capacity matrix, the fixed-versus-removable trade-off and the eight questions we are asked most.

48V / 60V / 72V voltage decision table

Locate your bike by motor rating, daily distance and everyday payload. Choosing a voltage is not choosing a premium tier — it is keeping the loaded bus current inside what your harness and controller can actually carry.

MOSFET rating must cover the full-charge voltage plus the back-EMF peak: a 72V system reaches 87.6V at full charge and 98.4V transient Vpeak during downhill regeneration, so 100V-rated MOSFETs are required. Check the motor back-EMF constant (Ke) and stator enamel temperature class before raising voltage — reversing that order causes batch rework.

grid_onCapacity matrix

Capacity matrix: work back from daily distance and payload

Two-wheeler delivery duty sits at 28–35 Wh/km combined (frequent stops, cruising in the 45km/h class); high-speed e-motorcycles sit at the lower end on open roads. Capacity comes from daily distance × consumption ÷ usable depth of discharge, plus roughly 20% margin.

Energy is computed at each platform nominal voltage (48V 51.2V / 60V 16S 51.2V / 72V 76.8V); pack weight includes shell, BMS and harness at roughly 7 kg/kWh (±5%), with 18.5 kg typical for the 60V 45Ah pack. Range bands differ within one voltage because the duty cycle differs: VT-2W7260 covers 120–160 km fully loaded at 180kg uphill, while VT-7260-SWAP at 97–127 km is computed on the high-speed e-moto basis of 32–42 Wh/km (the same pack returns about 116–145 km on the 28–35 Wh/km delivery basis). Payload, gradients, tyre pressure and riding style all move the result.

battery_charging_fullFixed vs removable

Fixed battery bay or removable swap pack?

A fixed pack is locked into the structure, which buys lower cost and a stiffer frame. A removable swap pack turns recharging from waiting into exchanging a block, at the cost of the shell, handle, lock and connector. Two questions decide it: how many trips the bike makes in a day, and whether there is anywhere to leave it on charge for six hours.

  • Choose removable when daily distance exceeds one pack of range, when the bike runs double shifts, when the rider has no fixed charging spot, or when the battery must be a separate asset from the vehicle.
  • Choose fixed when one pack covers the shift (about 90km or less), when there is a garage for overnight slow charging, and when lowest first cost matters most.
  • Real figures for a removable pack: the 60V 45Ah step weighs about 18.5 kg and lifts with one hand; the swap connector is rated for more than 10,000 insertions without arcing; 1C charging reaches full in 70 minutes, with about 70% in 30 minutes.
  • Safety prerequisites: an IP67 high-current aviation connector with keyed anti-reversal, a handle placed above the pack centre of gravity, and an IP67 drawn-aluminium plus flame-retardant ABS dual shell that passes the 30G three-axis shock fatigue test.

  • Bay dimensions and quick-release rail or handle clearance: leave 8–12mm all round and fit high-damping EVA foam so nothing touches hard
  • Controller low-voltage cut-off: lead-acid cuts at 52.5V on a 60V system while 16S LiFePO4 cuts at 44.0V, so the threshold must be reflashed or the gauge will dive
  • Charger: a lithium CC-CV charger that handshakes with the BMS is mandatory — never continue with a lead-acid constant-voltage unit
  • Comms harness: CAN 2.0B / RS485 / UART single-wire dashboard protocol is what carries SOC and fault codes to the display
helpE-motorcycle selection FAQ

The e-motorcycle battery questions we answer every week

Should my e-motorcycle run 48V, 60V or 72V?expand_more
Three numbers decide it: motor rating, daily distance and everyday payload. For 800W–1500W, within 70km a day, solo with light cargo, choose 48V (16S). For 1500W–2500W, 70–120km a day, with a delivery box, choose 60V. For 2500W–5000W+, 90km or more a day, two-up or mountain grades, choose 72V (24S). At the same 3000W at the axle, a 48V bus carries about 62.5A against 40.5A at 72V and copper loss is 55.5% lower — but 72V reaches 87.6V at full charge, so the controller must be rated 100V–120V automotive with reinforced insulation. Always check the motor back-EMF constant (Ke) before raising voltage.
How far will one battery take me?expand_more
Two-wheeler delivery sits at 28–35 Wh/km combined. On that basis, 60V 50–60Ah (VT-6050-LFP-SWAP) is sized for an 80–100km target range; a high-speed e-motorcycle sits at the lower consumption figure, where 72V 40Ah covers about 64–84km and 72V 60Ah about 97–127km. Size on your real daily distance plus roughly 20% margin rather than the biggest number in the table — the extra weight eats part of the range it was meant to add.
My original battery has faded — can I replace only the battery and keep the bike?expand_more
Yes. A replacement pack is looked up from the length, width and height of the bay you already have, so measure the box before choosing capacity; all three voltage steps have matching packs. Check three things at the same time: the controller low-voltage cut-off (lead-acid cuts at 52.5V on 60V, 16S LiFePO4 at 44.0V), a lithium CC-CV charger, and dashboard telemetry compatibility. Where a standard pack will not fit, the shell can be tooled to your bay dimensions.
Is a removable battery safe?expand_more
It comes down to three parts: shell, connector and lock. The pack uses an IP67 drawn-aluminium plus flame-retardant ABS dual shell and passes a 30G three-axis shock fatigue test. The connector is an IP67 high-current aviation type rated above 10,000 insertions without arcing. The lock needs keyed guidance so the pack cannot shake loose in service. The cells are automotive-grade LiFePO4, whose thermal self-decomposition temperature of 650°C is far above the 210°C of NMC, and the BMS derates above 60°C and cuts the MOS protection loop at 65°C.
How long does fast charging take?expand_more
At 1C high-rate charge, about 70% goes in within 30 minutes and a full charge completes in roughly 70 minutes — the precondition for high-turnover swap duty. On the standard 10–20A charger, a 60V 45Ah pack takes about 4–5 hours. In hot climates we recommend dropping to 0.5C or below to protect cycle life; the BMS derates automatically with cell temperature.
How do I choose a swap module?expand_more
Four things: bay dimensions and release style, pack capacity against daily distance, cabinet protocol, and anti-theft requirements. On specification, the 60V 45Ah step weighs about 18.5 kg and lifts with one hand, the connector is rated above 10,000 insertions, and the BMS natively integrates CAN 2.0B / RS485 / UART plus 4G Cat.1 with GPS, connecting directly to Gogoro and China Tower cabinet buses. The register whitepaper and C/C++ SDK ship with the pack, and a firmware engineer supports cabinet handshaking and stepped charge-current delivery.
What does an e-motorcycle battery cost?expand_more
Price moves with voltage platform, capacity, cell grade and the document set that ships with the container, so we publish no guess range. Send destination port, motor rating, daily distance and everyday payload and we will model FOB / CIF pricing and container allocation. If you are replacing a single pack, add the existing bay dimensions and capacity step.
Can an e-motorcycle go on the highway?expand_more
That depends on how the destination country classifies the vehicle and the rider: 48V platforms cruise economically at 25–35 km/h, 60V at 40–50 km/h and 72V reaches 55–75 km/h+, which in most markets puts the bike in motorcycle administration with plates, licence and insurance. Whether a given bike may use a highway, and under which class, follows the destination regulations in force — what we control is making the battery and electronics meet the applicable market access route (India AIS-156 Phase 2, Indonesia SNI, Thailand TISI, Vietnam QCVN 91) with UN38.3, MSDS and a Class 9 packing certificate shipped alongside.
