These advances have transformed e-bikes from niche products into mainstream transportation options.

Early e-bikes relied on heavy lead-acid batteries with limited capacity and short lifespans. Today's options offer dramatically improved performance using various lithium-based chemistries. Let's examine the primary technologies powering modern electric bikes.

Lithium-Ion (Li-ion): The Current Standard

How Lithium-Ion Batteries Work

Lithium-ion batteries remain the most common technology in premium e-bikes, including most of the MoVcan lineup. These batteries work through the movement of lithium ions between a positive cathode (typically lithium-cobalt oxide, lithium-manganese oxide, or lithium-nickel-manganese-cobalt) and a negative anode (usually graphite).

During discharge, lithium ions flow from the anode to the cathode, producing electricity. During charging, this process reverses. Learn more about this process on our battery technology page.

Nickel-Metal Hydride (NiMH): The Legacy Option

How NiMH Batteries Work

Though largely phased out of premium e-bikes, some entry-level or older models still use nickel-metal hydride technology. These batteries store hydrogen ions in a metal alloy, offering a middle ground between older lead-acid and modern lithium technologies.

Advantages of NiMH Batteries

• Lower cost: More affordable than lithium-based options
• Simple battery management: Less complex control systems required

• Shorter cycle life: Typically 300-500 complete charge cycles
• Limited peak power: Less suitable for high-performance applications

Battery Specifications Explained

Understanding battery specifications helps you compare options effectively:

Voltage (V)

E-bike batteries typically range from 24V to 72V, with most premium models using 36V, 48V, or 52V systems. Higher voltage generally provides:

• More efficient power delivery
• Better hill-climbing performance
• Higher potential top speeds

MoVcan primarily uses 48V and 52V systems for optimal performance across varied terrain.

Capacity (Ah)

Ampere-hours indicate how much energy a battery can store. Most e-bike batteries range from 8Ah to 20Ah. Multiplying voltage by capacity gives you watt-hours (Wh), the most accurate measure of total energy storage. For example:

• 48V × 10Ah = 480Wh
• 36V × 15Ah = 540Wh

Cycle Life

One "cycle" represents a complete discharge and recharge of a battery. Modern lithium-ion batteries typically offer:

• Budget cells: 500-700 cycles
• Premium cells: 800-1000 cycles
• LFP cells: 2000-3000 cycles

After these cycles, batteries typically retain about 70-80% of their original capacity.

C-Rate

The C-rate indicates how quickly a battery can safely discharge relative to its capacity. Higher C-rates allow more powerful acceleration and better hill-climbing:

• 1C: Discharge in 1 hour (basic e-bikes)
• 2C: Discharge in 30 minutes (standard performance)
• 3C+: Discharge in 20 minutes or less (high-performance models)

MoVcan uses cells rated for continuous 3C discharge in our performance models, enabling stronger acceleration and more consistent hill-climbing power.
