Batteries de vélos électriques 36V vs 48V : Quelle est la meilleure solution ?

As the global electric bicycle market continues to grow, the choice of battery voltage is becoming a topic of great interest to vehicle brands, system integrators, and channel customers. Among the many specifications, 36V and 48V electric bicycle batteries are the two most widely used solutions. So, what are the differences between them? Which one is more suitable for your product positioning and target market?

As a one-stop solution provider specializing in customized and mass-produced lithium batteries, this article will provide a comprehensive analysis from the perspectives of performance, application scenarios, and selection logic.

Part 1. Why is Battery Voltage So Important?

Battery voltage not only affects the power output of the electric bicycle but also directly relates to:

Motor matching and efficiency

Maximum speed and climbing ability

Overall system stability

Battery current load and lifespan

Cost structure and market compliance

Therefore, there is no absolute “better” choice between 36V and 48V; it’s about which is more suitable.

Part 2. 36V Electric Bicycle Batteries: Mature, Stable, and Highly Compliant

1. Typical Characteristics of 36V Batteries

Common configurations: 36V 10Ah / 12Ah / 14Ah

Suitable motor power: 250W–500W

Relatively low operating current

Mature system, strong versatility

2. Core Advantages of 36V Batteries

Higher regulatory compliance
In markets such as Europe and Japan, 36V systems are more likely to meet local electric bicycle regulations.

More energy-efficient
Suitable for urban commuting, with stable range performance.

More cost-effective
Suitable for large-volume OEM projects and entry-level models. 3. Applicable Scenarios

Urban commuting electric bicycles

Lightweight electric-assist bicycles

Models that prioritize range and comfortable riding experience

Part 3.48V Electric Bicycle Batteries: Stronger Power, Higher Performance

1. Typical Characteristics of 48V Batteries

Common configurations: 48V 13Ah / 15Ah / 20Ah

Suitable motor power: 500W–1000W and above

Lower current at the same power

Higher requirements for BMS and structural design

2. Core Advantages of 48V Batteries

Puissance accrue
Faster acceleration and significantly improved climbing ability.

Higher system efficiency
Under high power output, battery and motor heating are more controllable.

Suitable for mid-to-high-end and special models
Such as fat tire electric bikes, mountain electric bicycles, and cargo eBikes.

3. Applicable Scenarios

High-load or hilly riding environments

American market and performance-oriented models

User groups with higher demands for acceleration and power response

Part 4. From a Manufacturer’s Perspective, How to Choose?

According to Yizhan Electronic Technology, the correct selection logic should start from product positioning:

If your goal is urban commuting, the European market, and lightweight design
👉 36V electric bicycle batteries are a safer choice

If your product emphasizes power performance, complex road conditions, or high load capacity
👉 48V batteries will provide significant advantages

More importantly, the choice of battery voltage should be designed in conjunction with the following factors:

Motor power and controller parameters

BMS protection strategy

Battery structural strength and waterproof rating

Vehicle heat dissipation and safety design
