QWW 48V 36V Electric Bike Lithium ion Battery Review: A Comprehensive Look

If you are in the market for an electric bike or tricycle battery, the QWW 48V 36V lithium ion battery is worth considering. This versatile battery is suitable for a wide range of motor powers and comes in various capacities to suit your specific needs.

Before making a purchase, it’s crucial to carefully consider the specifications to ensure the battery is compatible with your motor and fits in the desired location. Let’s take a closer look at the product description and key features of the QWW electric bike lithium ion battery.

Product Description

The QWW battery is designed to match the voltage of your motor, with options for 36V and 48V, and also offering 52V, 60V, and 72V for specific models. The maximum power and maximum current should be equal to or greater than that of your motor, ensuring optimal performance. For example, a 48V 1000W 30amp battery can be used with a 48V 500W 20amp motor, but not vice versa.

Additionally, the location where you plan to place the battery must have enough space for the chosen battery. Moreover, for long box batteries similar to Hailong batteries, understanding the differences between each type is essential for proper installation.

The QWW battery boasts no technical barriers, making it suitable for most motors. It offers a wide range of options for voltage (36V, 48V, 52V), capacity (10AH, 13AH, 15AH, 20AH), and power (100W-1400W), ensuring you find the perfect fit for your electric bike or tricycle.

Hailong (Long Box) Battery Installation

When receiving the battery, it’s essential to follow specific steps to install the Hailong (long box) battery properly. This includes fixing the mounting plate to the ebike, ensuring the correct orientation, and connecting the discharge plug to the controller.

Furthermore, correct installation of Hailong batteries on the triangle frame requires careful consideration of the position of the threaded hole of the tripod and the mounting plate. If the required conditions are not met, the Hailong battery cannot be correctly installed on the frame.

Different Types of Hailong Batteries

The QWW battery offers various types of Hailong batteries, including Hailong-1, Hailong-2, Hailong-3, and Hailong-3B, each with unique features and installation requirements. From USB charging capabilities to different mounting plate designs, each type caters to specific needs and preferences.

Triangle Battery, Rear Frame Battery, and Universal Battery Pack

In addition to Hailong batteries, the QWW electric bike lithium ion battery also offers options for triangle battery, rear frame battery, and universal battery pack. Each type has its own set of advantages and installation requirements, catering to different preferences and needs.

The triangle battery, for example, is larger and heavier, providing more electrical energy for longer mileage. However, it requires a sufficient amount of space in the ebike’s triangle frame for installation.

On the other hand, the rear frame battery is square in shape and can be installed in various positions, offering versatility and ease of installation. And the universal battery pack is designed to be applied to various power supply systems, including electric bicycles, tricycles, motorcycles, and scooters.

It’s important to note that the battery size varies depending on the parameters, and it can also be customized according to specific requirements, offering flexibility for different applications.


The QWW 48V 36V electric bike lithium ion battery is a versatile and reliable option for electric bike and tricycle owners. With a variety of options available to suit different motor powers and installation preferences, it offers flexibility and performance.

When choosing a battery for your electric bike or tricycle, meticulous attention to detail is crucial to ensure compatibility and optimal performance. Whether you opt for a Hailong battery or a universal battery pack, the QWW battery range has something to offer for every need.
