Why Choose a Hailong G80-Style E-bike Battery?
Battery integration is an important engineering consideration when developing or upgrading an electric bicycle. A battery needs to provide sufficient energy while fitting securely onto the bicycle frame and remaining convenient for daily use.
The Hailong-style configuration is widely associated with removable e-bike battery designs because the battery can be detached from the bicycle for charging, inspection, storage, or maintenance. The G80-style structure combines this removable concept with a housing designed for practical installation on electric bicycles.
For manufacturers, a standardized housing concept can also simplify product development. Instead of designing a completely new battery enclosure for every bicycle model, engineers can evaluate the available dimensions, electrical requirements, mounting position, connector configuration, and motor rating before selecting an appropriate battery specification.
Yideng's product platform is designed for electric mobility manufacturers and distributors that require flexible configurations for different bicycle models and market requirements.
What Are the Key Features of the Battery?
The 21700 Waterproof E-bike Battery for Hailong G80 Electric Bicycle combines several design elements intended for practical electric mobility applications.
- Detachable Hailong-style housing: The removable structure supports convenient charging, maintenance, and battery replacement.
- Water-resistant housing design: The enclosure helps protect internal battery components from common outdoor environmental conditions.
- 18650 and 21700 cell options: Different cylindrical cell configurations can be selected according to capacity, discharge, space, and design requirements.
- Multiple voltage configurations: Available configurations include 36V, 48V, and 52V systems.
- Integrated BMS: Battery management protection helps monitor operating conditions and manage abnormal electrical events.
- Integrated lock system: The locking mechanism helps secure the removable battery during everyday riding.
- OEM customization: Voltage, capacity, cells, connectors, communication interfaces, and packaging can be customized for different projects.
These characteristics make the battery suitable for both new e-bike development projects and selected replacement or upgrade applications, provided that the electrical and mechanical specifications are correctly matched.
21700 Waterproof E-bike Battery Specifications
Battery selection should always begin with voltage, capacity, motor power, physical dimensions, cell configuration, and installation requirements. The following specifications summarize representative configurations available for this battery platform.
| Battery Configuration | Cell Configuration | Cell Type | Recommended Motor Power | Dimensions |
|---|---|---|---|---|
| 48V 20Ah | 13S4P | 21700-5Ah | Below 1000W | 368 × 127 × 90 mm |
| 48V 21Ah | 13S6P | 18650-3.5Ah | Below 1000W | 368 × 127 × 90 mm |
| 48V 17.5Ah | 13S5P | 18650-3.5Ah | Below 1000W | 368 × 109 × 90 mm |
| 48V 20Ah | 13S4P | 21700-5Ah | Below 1000W | 368 × 109 × 90 mm |
| 36V 21Ah | 10S6P | 18650-3.5Ah | Below 1000W | 362 × 92 × 90 mm |
| 48V 14Ah | 13S4P | 18650-3.5Ah | Below 1000W | 362 × 92 × 90 mm |
| 52V 14Ah | 14S4P | 18650-3.5Ah | Below 1000W | 362 × 92 × 90 mm |
Actual battery selection should be based on the complete electrical system rather than capacity alone. Motor voltage, controller compatibility, current demand, charger specification, available installation space, connector type, and riding conditions should all be evaluated before ordering.
How Does the Battery Structure Support E-bike Applications?
An electric bicycle battery must balance energy storage with physical installation requirements. A battery that provides high capacity but does not fit the frame or mounting system cannot deliver a practical solution.
The Hailong-style detachable housing used by this battery platform provides a compact and service-friendly configuration. Users can remove the battery from the bicycle when charging or carrying out maintenance, reducing the need to position the entire bicycle next to a charging point.
The combination of 18650 and 21700 cylindrical cells also gives manufacturers greater flexibility. 18650 cells can provide more arrangement flexibility when internal space is limited, while 21700 cells can support higher-capacity configurations within an appropriately designed battery pack.
For mountain e-bikes and fat tire bicycles, battery performance is especially relevant during acceleration, climbing, and longer-distance riding. A properly configured pack should therefore be matched to the motor and controller rather than selected simply by nominal capacity.
How Does the Built-in BMS Improve Battery Safety?
The Battery Management System, commonly known as BMS, is an essential part of a modern lithium battery pack. It monitors operating conditions and helps protect the battery when electrical parameters move outside the intended operating range.
The integrated BMS of this e-bike battery provides several protection functions:
- Over-charge protection
- Over-discharge protection
- Over-current protection
- Short circuit protection
- Temperature protection
These functions are particularly important during demanding riding conditions. Rapid acceleration, steep climbing, frequent starting and stopping, and extended riding can increase battery current demand. A properly configured BMS helps manage these conditions and supports stable battery operation.
However, BMS protection should not replace correct system design. The battery, charger, controller, motor, wiring, and connectors should be electrically compatible. Manufacturers should also follow appropriate lithium battery handling, charging, transportation, and storage requirements.
What E-bike Applications Can Use This Battery?
The flexible configuration of the battery makes it suitable for several light electric mobility applications. Typical applications include:
- Commuter e-bikes: Suitable configurations can provide practical daily riding power while maintaining a removable battery design.
- Mountain e-bikes: Stable discharge performance is important for climbing and variable terrain.
- Fat tire electric bicycles: Higher-capacity configurations can support applications where additional riding range is required.
- Electric scooters: Selected configurations can be adapted for lightweight electric mobility equipment.
- Light electric motorcycles: Customized versions may be considered for compatible low-power applications.
- Outdoor power equipment: Certain battery configurations can also support portable power stations and other high-power equipment.
For commercial projects, manufacturers should provide the battery supplier with the target motor power, controller parameters, desired range, mounting dimensions, connector requirements, and operating environment. These details help engineers determine a more appropriate battery configuration.
What OEM Customization Options Are Available?
Electric bicycle manufacturers often need battery configurations that differ from standard catalog models. Frame geometry, motor rating, target riding range, controller current, charger specifications, and regional market requirements can all influence battery design.
Yideng supports customization in several areas, including:
| Customization Area | Typical Requirement |
|---|---|
| Voltage | 36V / 48V / 52V |
| Capacity | Different Ah configurations based on range requirements |
| Cell Combination | 18650 or 21700 cylindrical cell arrangements |
| Connector | Connector selection according to vehicle electrical architecture |
| Communication | Customized communication interface when required |
| Packaging | Customized battery packaging and product presentation |
This approach can help OEM buyers move from prototype development to volume production without completely redesigning the battery around every vehicle model. For manufacturers evaluating suppliers, it is useful to confirm sample testing, battery specifications, connector compatibility, BMS parameters, packaging requirements, and production lead times before placing a bulk order.
