Agricultural pruning shears are mainly used for branch pruning in orchards, nurseries, landscaping, and agricultural planting areas. Unlike ordinary household power tools, agricultural pruning shears often need to operate continuously for several hours and may encounter branches of different thicknesses, frequent starts and stops, high and low outdoor temperatures, dust, and mobile operation. Therefore, the battery needs to provide sufficient runtime and stable output while controlling its weight and size within the limited space of the tool body.
Lithium batteries are gradually becoming an important power source for cordless agricultural pruning shears. By properly selecting the cells, voltage, capacity, BMS, and battery housing, a dedicated battery pack can be designed according to the pruning shears’ power, operating time, and installation space. Lithium iron phosphate batteries offer good safety, cycle performance, and stability, making them suitable for power tool applications that require repeated charging and discharging. For different models of agricultural pruning shears, customization services can also be provided for voltage, capacity, connection methods, housing dimensions, and communication functions, allowing the battery to work more effectively with the complete tool.
Basic Lithium Battery Requirements for Agricultural Pruning Shears
Stable Runtime Is Required for Continuous Operation
Agricultural pruning shears are generally not used only once for a short period but operate continuously during pruning tasks. When the orchard area is large, insufficient battery capacity requires workers to frequently stop to replace or charge the battery, which not only affects operational continuity but also increases the number of spare batteries required. Therefore, battery capacity needs to be calculated based on the pruning shears’ motor power, daily operating time, and actual load. A larger capacity is not always better, as increased capacity generally also results in increased weight.
Frequent Starts Require Stable Output
When pruning shears cut branches, the motor may need to provide a large amount of power within a short period. Especially when processing thicker branches, battery output capability directly affects motor operation. If the battery output capability is insufficient, the equipment may experience reduced power, unstable speed, or even protective shutdown. Therefore, when customizing a battery pack, it is necessary to consider not only “how many Ah” but also the motor’s rated power, peak power, and starting current when selecting suitable cells and a BMS.
Outdoor Operation Requires a More Reliable Battery Structure
Agricultural pruning shears are mainly used outdoors, and the battery may be exposed to dust, moisture, and different ambient temperatures. The battery housing needs to provide good protection while also considering vibration resistance, connector fixation, and long-term reliability. The battery pack can be designed according to the installation method of the pruning shears, with appropriate interfaces and mounting positions reserved so that the battery can be securely installed in the main unit, waist bag, or backpack-style battery box.
| Pruning Shear Application Requirements | Battery Design Priorities |
| Lightweight fruit tree pruning | Control weight while maintaining runtime |
| Long-term continuous operation | Increase battery capacity |
| High-load cutting of thick branches | Improve continuous and instantaneous output capability |
| Backpack-style battery | Weight distribution and wearing comfort |
| Complex outdoor environments | Housing protection and connection reliability |
| High-frequency charging and discharging | Select cells suitable for repeated cycling |
How LiFePO4 Battery Packs Are Used in Agricultural Pruning Shears
Design the Battery Pack According to the Operating Voltage
The battery specifications used by agricultural pruning shears are not completely identical. Common designs need to be determined according to the operating requirements of the motor and controller. A battery pack can achieve the required operating voltage by connecting different numbers of cells in series, while the capacity can be adjusted by changing the number of cells connected in parallel. For example, different power versions may exist within the same series of pruning shears, so the battery voltage and capacity can also be adjusted accordingly. For projects with confirmed motor, controller, and charger specifications, the battery pack can be designed according to these parameters instead of directly using a standard battery.
Adjust Operating Time Through Battery Capacity
Battery capacity is usually expressed in Ah. Once the voltage is determined, increasing the capacity can increase the stored energy and thereby extend the equipment’s operating time. However, increasing capacity does not necessarily make the battery suitable for every pruning shear. Battery size, weight, installation position, and the way the operator carries the battery will all be affected. For handheld pruning shears, an excessively heavy battery may increase the burden during long-term operation. For backpack-style equipment, a larger-capacity battery can be used, with the weight distributed through a battery box or backpack. Therefore, battery customization needs to consider runtime, overall equipment weight, and installation space at the same time.
BMS Provides Battery Operation Protection
The BMS is an important component of the battery pack and can manage the battery’s operating status. According to battery design and equipment requirements, functions such as overcharge, over-discharge, overcurrent, and temperature protection can be configured. If the pruning shears’ controller needs to communicate with the battery, the corresponding communication method can also be selected according to project requirements. A customized BMS can be designed based on battery capacity, operating current, and overall equipment control requirements instead of simply using a fixed specification. Deligreen currently provides cells, battery packs, BMS, and related accessories, and supports customized battery pack designs, including BMS, housings, connectors, and other configurations. CAN, RS485, Bluetooth, and other communication options can also be provided according to project requirements.
Customization Process for Agricultural Pruning Shear Lithium Batteries
Confirm Pruning Shear Parameters
Before customization begins, the basic parameters of the pruning shears need to be provided, such as operating voltage, motor power, target runtime, maximum operating current, battery installation position, and charger specifications. If an existing battery is available, the original battery label, dimensions, and connector information can also be provided. This information helps engineers determine the number of cells, battery capacity, BMS specifications, and housing structure.
Design the Battery Structure and Interfaces
After the basic parameters are determined, the battery pack dimensions, connectors, cables, mounting method, and housing can be further designed. The available battery installation space varies significantly between different pruning shears, so the battery does not necessarily need to use standard dimensions. If the battery needs to be placed in a waist bag or backpack-style battery box, cable length, connection and disconnection methods, and pulling forces during wearing and operation also need to be considered.
Enter Mass Production After Testing
After the sample is completed, charging and discharging, output, protection functions, and complete equipment compatibility can be tested. Once stable operation between the battery and pruning shears is confirmed, mass production can be arranged according to the order quantity. For agricultural pruning shear batteries intended for export, the target market’s transportation and product documentation requirements should also be confirmed in advance. Deligreen can provide relevant transportation test summaries, Safety Data Sheets, and compliance documents according to applicable battery models, and supports CE, UN38.3, MSDS, RoHS, and other documentation services. Specific documents are confirmed according to product and market requirements.

Battery Solutions for Different Agricultural Pruning Equipment
Handheld Electric Pruning Shears
Handheld equipment is relatively sensitive to battery weight. An excessively heavy battery increases the burden on the wrist and arm, so the capacity and weight generally need to be properly balanced. For these products, an appropriate capacity can be selected according to daily operating time, while unnecessary volume can be reduced through an optimized cell configuration. The battery housing also needs to consider frequent handling, installation, and removal. The connector should remain secure to avoid loosening after long-term use.
Backpack-Style Agricultural Pruning Shears
Backpack-style equipment can accommodate a larger battery, making it possible to use a higher-capacity battery pack. The battery can be secured through a backpack or dedicated battery box and connected to the pruning shears through a cable. This design reduces the weight of the handheld section and extends continuous operating time. For large-area orchard pruning, landscaping maintenance, and other applications, spare batteries and charging solutions can be designed according to actual operating time.
High-Power Pruning Equipment
High-power pruning shears require stronger power output when cutting thick branches, so the battery needs to have good discharge capability. The cells, battery connection method, BMS, and cables all need to be designed according to the equipment’s operating current. If the equipment has significant peak power requirements, the battery’s instantaneous output capability also needs to be considered to prevent a situation where the battery has sufficient stored energy but cannot meet the equipment’s instantaneous power demand.
