The 15L Agricultural Battery Electric Knapsack Sprayer is a newly upgraded electric sprayer developed by Crosstec for professional agricultural and commercial spraying scenarios. Different from conventional knob-adjust sprayers, this model adopts a local Bluetooth handle control system to simplify daily spraying operations, effectively reducing repetitive labor and improving field working efficiency.
Designed for orchard maintenance, greenhouse farming, landscape care, and public sanitation disinfection, this battery-powered sprayer integrates steady-pressure diaphragm pump technology, chemical-resistant tank structure, and ergonomic backpack support. It delivers stable and consistent spraying performance for long-hour outdoor work. Notably, the Bluetooth function only supports wireless linkage between the spray gun and the main unit, without mobile APP remote control, ensuring more stable and fail-proof field operation.
Traditional backpack sprayers require operators to stop working, bend down, and twist the body knob repeatedly to adjust liquid flow. Frequent adjustments disrupt spraying continuity, cause uneven coverage, and bring long-term waist and hand fatigue.
This upgraded Bluetooth sprayer relocates all flow adjustment buttons to the spray gun handle. Operators can increase or decrease spray volume freely while walking and spraying. No stopping, no bending, no posture changes during adjustment. Built-in vibration and beep feedback deliver clear operational prompts for every button press, enabling blind and accurate operation.
The handle buttons remain highly operable even with thick protective gloves or wet slippery hands. Advanced versions support custom flow preset memory, allowing one-touch switching between fine mist and high-pressure jet modes to fit diverse crop and disinfection needs.
Equipped with a professional-grade diaphragm pump, the machine maintains stable pressure and uniform atomization during continuous intermittent operation. It effectively avoids uneven spray output, sudden flow changes, and liquid leakage that commonly occur on ordinary sprayers.
Optimized for harsh outdoor agricultural environments, the pump features strong corrosion resistance and a long service life, perfectly compatible with water-based pesticides, herbicides, liquid fertilizers, and daily disinfectants. It meets the requirements of long-term commercial and farm continuous operation.
The 15-liter tank is manufactured from high-strength modified polypropylene material, featuring excellent UV resistance, impact resistance, and chemical corrosion resistance. It can withstand long-term outdoor sun exposure and harsh weather conditions without aging or deformation.
The large capacity greatly reduces refilling frequency, making it ideal for large orchards, vast farmland, greenhouses, and landscape projects. Clear graduated scales on the tank ensure precise liquid mixing and scientific chemical proportioning for standardized spraying work.
The sprayer adopts a humanized load-bearing structure, equipped with widened breathable shoulder straps and a thickened back cushion. The balanced weight distribution effectively relieves shoulder and back pressure, avoiding stuffiness and fatigue during long-hour carrying.
Suitable for all-day continuous operation by farmers, gardeners, and sanitation workers, the wearable design greatly improves working comfort compared with traditional rigid backpack sprayers.
Most conventional electric sprayers rely on body-mounted knob adjustment, which forces workers to pause spraying and look down to operate. This not only wastes working time but also easily causes missed spraying or overlapping coverage, reducing overall operation quality.
With Bluetooth handle control, all adjustments are completed on the hand-held spray gun. Operators can always keep their eyes on the working target, ensuring continuous, uniform, and precise spraying. The whole operation process is more efficient, safer, and more in line with the high-frequency working habits of professional teams.
In addition, the button-type adjustment adapts to more complex working conditions, including low-light night work, fully protected glove operation, and humid field environments, realizing stable and error-free adjustment in all scenarios.
This 15L Bluetooth backpack sprayer is widely applicable for various civilian and commercial spraying tasks, including:
*Orchard & vineyard pest control and foliage fertilization
*Greenhouse and vegetable farm daily maintenance and chemical spraying
*Urban landscape, garden, and green belt maintenance
*Public area sanitation, disinfection, and epidemic prevention work
*Small-scale forest and plantation management
Note: Do not fill with strong corrosive solvents or high-viscosity undiluted stock solutions to avoid equipment damage.

1. Can this sprayer be controlled by mobile phone Bluetooth?
No. The Bluetooth system only realizes wireless connection between the spray gun and the main unit. It does not support mobile phone pairing or remote APP control, ensuring more stable signal in complex field environments.
2. Will the Bluetooth connection disconnect frequently?
The connection is stable in open field conditions. Signal fluctuation may occur in dense branches or strong electromagnetic interference environments, which can be recovered quickly by restarting the device.
3. Is the Bluetooth version necessary for ordinary household use?
The Bluetooth handle version is more suitable for teams and workers who need frequent flow adjustment. For occasional low-frequency use, the traditional knob version is more cost-effective.
4. Do you support batch customization and exclusive branding?
Yes. We offer one-stop private label customization, customized packaging, and product parameter adjustment services to meet diverse market sales needs.
