With the rapid growth of the global electric bicycle market, brand differentiation has gradually extended from the overall appearance of the vehicle to the core component – the battery system. The battery not only determines the range, safety, and lifespan of the electric bicycle but also directly affects the end user’s riding experience and brand reputation.
This article will systematically introduce how to customize a suitable battery pack for your electric bicycle brand from a brand perspective.
Part 1. Why Do Electric Bicycle Brands Need Customized Battery Packs?
Against the backdrop of increasingly homogenized standard batteries, customized batteries are becoming an important way for brands to enhance their competitiveness.
The core value of customized batteries includes:
Perfect matching with the overall vehicle structure (frame, downtube, rear rack, etc.)
Optimized range and power output, improving the riding experience
Improved safety, reducing after-sales and recall risks
Support for brand appearance and interface customization, enhancing brand recognition
Meeting the regulations and certification requirements of different markets
Part 2. Key Parameters for Customizing Electric Bicycle Battery Packs
Before customizing a battery, clarifying technical requirements is the first step. Yizhan Electronics usually assists clients in conducting a systematic evaluation from the following dimensions:
1. Voltage Platform Selection
Common electric bicycle battery voltages include:
36V: Urban commuting, leisure riding
48V: Mountain bikes, commuting + medium to high-speed requirements
52V / 60V: High-performance or special application models
Different voltages directly affect motor matching, power output, and regulatory compliance.
2. Capacity and Range Requirements
Capacity is usually expressed in Ah / Wh:
10Ah–14Ah: Short-distance commuting
15Ah–20Ah: Medium to long-distance riding
Above 20Ah: High-end or long-range models
3. Cell Selection
The battery cell is the “heart” of the battery pack, directly determining performance and lifespan.
Yizhan Electronics supports various solutions:
21700 / 18650 cylindrical cells
Ternary lithium / Lithium iron phosphate (LiFePO₄)
Leading brands or high-consistency domestic cells
We insist on cell sorting, grouping, and traceability management to ensure that each battery pack performs consistently and reliably.
Part 3. Smart BMS: The Core of Electric Bicycle Battery Safety
In Yizhan Electronics’ view, BMS is not an option, but a standard feature. Our eBike smart BMS supports:
Overcharge / Over-discharge / Overcurrent / Short-circuit protection
Real-time temperature monitoring and thermal management
Cell voltage balancing to extend service life
Accurate SOC estimation
CAN / UART / Bluetooth communication (optional)
For high-end brands, we can also provide a Bluetooth BMS + App integration solution to help customers create intelligent product experiences.
