Electric Motorcycle Battery: The Complete Buying Guide (2025 Edition)

Choosing the right battery is critical. It affects how far you can ride, how fast you accelerate, and how much you’ll pay over time. In this updated 2025 guide, we break down everything you need to know before buying a battery for your electric motorcycle—from types and sizes to pricing, lifespan, and the best options for different riding needs.

Part 1. What is an electric motorcycle battery?

An electric motorcycle battery is the energy storage unit that powers the electric motor. It replaces the engine and fuel tank in traditional motorcycles. The battery directly determines:

• Range (how far you can ride)
• Power output (acceleration + torque)
• Top speed
• Weight distribution
• Charging time
• Total ownership cost

In short, the battery is the most important—and the most expensive—component of an electric motorcycle.

Part 2. Electric motorcycle battery types compared

Different electric motorcycles use different battery chemistries. Each has unique strengths, price ranges, and performance characteristics.

1 Lead-Acid (SLA / AGM)

The oldest rechargeable battery type, still used in low-cost scooters.

Advantages:

• Cheapest option
• Easy to replace
• Suitable for light-duty use

Disadvantages:

• Very heavy
• Short lifespan (300–500 cycles)
• Low energy density → very short range
• Poor cold-weather performance

Best for: Budget scooters under 2kW

2 Lithium-Ion (Li-ion / NCM / NCA)

The industry standard for modern electric motorcycles.

Advantages:

• High energy density → long range
• Lightweight
• Good power output for acceleration
• Lifespan 800–1200 cycles

Disadvantages:

• Requires BMS protection
• Sensitive to extreme temperatures
• Higher upfront cost

Best for:

Commuters, mid-range e-motorcycles, performance machines

3 Lithium Iron Phosphate (LiFePO4 / LFP)

A safer and longer-lasting version of lithium technology.

Advantages:

• Extremely safe (thermal-stable)
• Very long lifespan: 2000–3500 cycles
• Withstands high temperatures
• Low degradation

Disadvantages:

• Lower energy density → slightly heavier
• Bulkier at the same capacity

Best for:

Long-term users, daily riders, hot climates, delivery fleets

4 NiMH (Nickel Metal Hydride)

Less common now but used in earlier EVs.

Advantages:

• More eco-friendly than lead-acid
• Stronger durability

Disadvantages:

• Heavy
• Low efficiency
• Rare in electric motorcycles today

Best for: Older models / legacy systems

Part 3. Electric motorcycle battery voltage explained

Voltage determines how much power the battery can deliver. Higher voltage = better acceleration and higher top speed.

Common Voltages in e-Motorcycles

• 48V – small scooters, delivery bikes
• 60V – mid-power commuters
• 72V – performance electric motorcycles
• 96V+ – high-performance / racing e-motorcycles

Always match your battery voltage to your motorcycle’s controller and motor.

Part 4. Electric motorcycle battery size guide

Battery “size” refers to physical dimensions AND electrical specifications.

1 Common Physical Sizes

Electric motorcycles often use standardized modules or custom packs:

• 18650 cells
• 21700 cells
• Prismatic LiFePO4 modules

2 Common Pack Configurations (Ah × Voltage)

Higher Ah = longer riding distance.

3 How to Choose the Right Size

Check:

• Battery compartment size
• Motor power (kW)
• Daily riding distance
• Charging frequency

Part 5. Battery capacity and weight

Capacity (Ah / Wh / kWh)

• Ah = storage (basic measure)
• Wh = Ah × Voltage
• kWh = total usable energy

Example:

A 72V 40Ah battery = 2.88 kWh.

More kWh = more range.

Weight

• Lead-acid: very heavy
• Li-ion: lightest
• LiFePO4: balanced

A lighter battery improves:

✔ handling

✔ acceleration

✔ efficiency

Part 6. Electric motorcycle battery price (2025 guide)

Price depends on chemistry, voltage, capacity, brand, and BMS quality.

Typical 2025 Price Ranges

Factors Affecting Price

• Capacity (Ah / kWh)
• Chemistry (Li-ion vs LiFePO4)
• BMS safety features
• Voltage (48V vs 72V vs 96V)
• Brand reputation
• Cycle lifespan

Higher-priced batteries often deliver lower cost-per-cycle.

Part 7. How long do electric motorcycle batteries last?

Battery life is measured in charge cycles.

Typical Lifespan

Battery TypeCycle LifeYears (daily use)Lead-Acid300–5001–2 yearsLithium-ion800–12002–4 yearsLiFePO42000–35005–8 years

Factors That Reduce Lifespan

• Overcharging
• Deep discharge (0–10%)
• High current draw
• Extreme heat (>45°C)
• Low-quality BMS
• Storing at 100% for long periods

Tips to Extend Lifespan

• Keep charge between 20%–80%
• Avoid high temperatures
• Use the correct charger
• Store at 50–60% if unused

Part 8. Best batteries for electric motorcycles (By use case)

✔ Best Overall Battery

Lithium-ion (NCM/NCA)

High energy density + long range.

✔ Best for Long Lifespan / Daily Commuters

LiFePO4 (LFP)

Up to 3500 cycles, excellent safety.

✔ Best Budget Option

Lead-acid

Only for low-speed motorcycles.

✔ Best for Performance Bikes

72V or 96V Lithium-ion Pack

High discharge rate = strong acceleration.

Part 9. Electric motorcycle vs gas motorcycle: battery impact

Electric motorcycles win in:

• Lower operating cost
• Instant torque
• No oil changes
• Quiet operation
• Eco-friendly

Gas motorcycles still offer:

• Longer range
• Faster refueling

But as battery technology advances, electric motorcycles are closing the gap quickly.
