Cordless electric lawn mowers eliminate the limitations of power cords, making them more flexible to use and suitable for home gardens, landscaping maintenance, lawn care, and professional landscaping operations. Compared with ordinary small power tools, cordless lawn mowers usually require more stable current output when starting the motor, performing continuous cutting, or dealing with thicker grass. If the battery capacity is insufficient, the operating time will be shortened; if the battery discharge capability is unsuitable, the equipment may experience reduced power, overheating, or frequent protection activation. Therefore, when designing batteries for cordless electric lawn mowers, customization needs to be carried out according to motor power, operating time, installation space, and operating environment.
What Requirements Do Electric Lawn Mowers Have for Lithium Batteries?
Stable Power Is Required for Continuous Operation
Cordless electric lawn mowers are usually powered by lithium batteries for brushless motors or other types of motors. During mowing, the cutting blade continues to rotate, and the motor load may increase when cutting dense grass, wet grass, or tall grass. This means that battery design cannot focus only on capacity, but must also consider actual discharge capability. The battery needs to maintain relatively stable voltage and current output while the equipment is operating, allowing the motor to receive continuous power. If battery capacity is simply increased without considering discharge capability, a situation may occur where “the battery has plenty of energy, but the mower lacks power during operation.” Therefore, when customizing a battery, the motor parameters and actual operating conditions need to be considered together.
Operating Time Needs to Be Determined According to the Application Scenario
Battery capacity is usually expressed in Ah. Voltage and capacity together determine how much energy the battery can store. For example, a 48V 10Ah battery has a theoretical energy of approximately 480Wh, while a 48V 20Ah battery has approximately 960Wh. Actual operating time is also affected by motor power, lawn conditions, blade load, operating method, and ambient temperature, so runtime cannot be determined simply based on capacity.
| Battery Specification Theoretical Energy Application Approach | ||
| 24V 10Ah | 240Wh | Small lawn mowing equipment |
| 36V 10Ah | 360Wh | Home garden equipment |
| 40V 10Ah | 400Wh | Common cordless landscaping tools |
| 48V 10Ah | 480Wh | Higher-power equipment |
| 48V 20Ah | 960Wh | Long-duration operating requirements |
The above values are theoretical energy calculations. Actual runtime needs to be confirmed according to the specific mower power and operating load.
Battery Weight Also Affects the Mowing Experience
Lawn mowers need to be moved frequently. If the battery is too heavy, it will increase the overall weight of the equipment and cause greater fatigue during long-term operation. Therefore, battery design should not focus solely on pursuing “large capacity.” By selecting suitable LiFePO4 cells, arranging the cell configuration reasonably, and optimizing the battery housing structure, a better balance can be achieved among capacity, weight, and available space. For backpack, handheld, and push-type lawn mowing equipment, different structures also have different requirements for battery dimensions. Suppliers can customize the battery according to the battery compartment dimensions, connector position, and mounting method provided by the customer.
How Can LiFePO4 Batteries Be Used in Cordless Lawn Mowers?
LiFePO4 Cells Provide Stable Power
LiFePO4 batteries offer good safety, stability, and cycle performance, making them suitable for equipment that requires repeated charging and discharging. Batteries used in landscaping tools that operate frequently may undergo a large number of charge and discharge cycles, so cell quality directly affects the service life of the product. During battery pack production, cells can be connected in series and parallel according to the required voltage and capacity. For example, a single LiFePO4 cell typically has a nominal voltage of 3.2V. If a battery pack of approximately 51.2V is required, 16 cells can be connected in series to form a 16S configuration. The specific number of series and parallel connections needs to be determined according to the lawn mower motor, electronic control system, and charger parameters.
The BMS Protects the Battery Pack
The BMS is the Battery Management System and plays an important role in battery pack protection and management for lawn mowers. It can monitor and protect against overcharging, over-discharging, overcurrent, abnormal temperature, and other conditions according to the operating status of the battery pack. Cordless lawn mowers may experience noticeable current changes during startup and cutting, so the BMS needs to be selected according to the actual operating current of the equipment. If the BMS rated current is too low, the equipment may frequently trigger protection during operation. If the configuration is inappropriate, it may also affect the normal use of the battery pack. During customization, the BMS current rating, protection functions, temperature detection method, and communication requirements can be determined according to the battery specifications and equipment parameters.
The Battery Structure Needs to Fit the Mower Installation Space
The battery not only needs to “work properly,” but also needs to “fit inside.” The interior of a lawn mower is usually subject to limitations such as battery compartment dimensions, mounting structures, protection design, and connector positions. Therefore, customized batteries can be designed according to the dimensional drawings, physical samples, or battery compartment structure provided by the customer. The cell arrangement, connection method, housing material, connectors, and output cables can all be adjusted according to project requirements.

Cordless Lawn Mower Lithium Battery Customization Process
Confirm the Complete Equipment Parameters
To ensure that the battery is truly suitable for the equipment, it is generally necessary to confirm the lawn mower’s rated power, operating voltage, maximum operating current, expected operating time, charging method, and battery installation space. If the customer already has a mature product, they can directly provide product specifications, battery compartment dimensions, an existing battery sample, or battery structure drawings. The engineering team can determine the battery pack design based on this information. For newly developed cordless lawn mowers, battery solutions can also be designed according to the target power and runtime requirements.
Determine Capacity According to Operating Requirements
The larger the capacity, the higher the theoretical stored energy, but battery weight, volume, and cost will also increase accordingly. Therefore, a reasonable capacity needs to be selected according to the actual operating time. For example, if a lawn mower has an average operating power of approximately 500W and is equipped with a battery with approximately 1kWh of theoretical stored energy, it can theoretically provide approximately 2 hours of energy support under ideal conditions. However, actual operating time is also affected by motor efficiency, lawn load, and battery discharge conditions, so actual operating time is usually lower than the theoretical calculation. For home users, weight and portability may be more important; for landscaping maintenance personnel, continuous operating time may be a higher priority. The purpose of battery customization is to design according to the actual requirements of the equipment rather than requiring all customers to use the same specifications.
Conduct Sample Testing Before Mass Production
For new projects, battery sample testing is recommended first. After installing the sample battery into the lawn mower, startup, continuous mowing, load changes, charging, and temperature rise can be tested. After confirming that the battery and the complete equipment operate normally, mass production can begin, reducing the costs associated with later structural modifications and battery specification changes. During production, the cells, battery pack welding, BMS, voltage, capacity, protection functions, and finished products also need to be inspected to ensure stable quality across batch products.

The biggest advantage of cordless electric lawn mowers is convenience. They do not require a power cord to be dragged around, so they can be picked up and used directly. However, the battery is an important component that determines how well the equipment performs. If the battery capacity is too small, it will need to be recharged after a short period of mowing; if the battery is too heavy, it will increase the operating burden; if the discharge capability is unsuitable, it may also affect the mower’s power output. Therefore, when selecting lithium batteries for cordless lawn mowers, there is no need to pursue “large capacity” blindly. Instead, the battery should be selected according to the machine’s power, operating time, battery compartment dimensions, and operating environment. LiFePO4 batteries offer good safety and cycle performance and can be used in landscaping tools that require long-term repeated operation.
