15 Litre Battery Knapsack Sprayer with 4Ah Lithium Battery - Backpack Sprayer for Gardens and Farms

4Ah lithium-ion battery eliminates manual pumping:

The Dargan 15 litre backpack sprayer is powered by a high-capacity 4Ah rechargeable lithium-ion battery, providing up to 4 hours of continuous spraying on a single charge. Simply press the trigger and spray—no manual pumping, no hand fatigue, and no pressure loss during operation. The electric pump delivers consistent spray pressure from the first spray to the last, covering large areas efficiently without interruption.

15 litre tank capacity reduces refills on larger areas:

The generous 15 litre tank handles large gardens, allotments, farms, and commercial spraying without frequent refilling. Fewer stops mean faster completion of spraying tasks across lawns, flower beds, vegetable patches, hedgerows, and hard surfaces. The large capacity makes this sprayer suitable for both domestic gardeners with larger properties and professional landscapers or groundskeepers.

Multiple nozzles and extendable lance for precise application:

The included extendable lance reaches areas that standard sprayers cannot, including tall hedges, elevated flower beds, and awkward corners. Multiple interchangeable nozzles provide different spray patterns—fine mist for delicate plants, concentrated stream for targeted weed treatment, and wide fan for broad lawn coverage. Switch between nozzles in seconds to match the application.

Padded backpack design for comfortable extended use:

Cushioned shoulder straps and a padded backrest distribute weight evenly across the back, reducing fatigue during longer spraying sessions. The lightweight design at approximately 5.5kg empty keeps the load manageable even when the tank is full. The well-balanced construction prevents the sprayer from shifting during walking and bending.

Setup and Care

Initial charging and battery preparation:

Fully charge the 4Ah lithium-ion battery before first use using the included charger. Connect the charger to the battery and allow it to reach full charge before attaching to the sprayer unit. The battery indicator will confirm when charging is complete and the sprayer is ready for operation.

Filling the tank and selecting nozzles:

Fill the 15 litre tank with your chosen solution through the wide-mouth opening at the top. Select the appropriate nozzle for your application—fine mist for delicate plant treatment, fan nozzle for broad lawn coverage, or concentrated stream for targeted weed control. Attach the nozzle securely to the lance before spraying.

Operating the sprayer for best results:

Adjust the shoulder straps and backrest for a comfortable, balanced fit before beginning. Press the trigger to activate the electric pump and begin spraying. Maintain a steady walking pace for even coverage. Use the extendable lance to reach elevated or recessed areas. Release the trigger to stop spraying immediately.

Cleaning and storage for long-term performance:

Empty any remaining solution from the tank after each use. Rinse the tank, hose, lance, and nozzle thoroughly with clean water to prevent chemical residue build-up. Run clean water through the pump system for 30 seconds to flush internal components. Allow all parts to dry fully before storage. Remove the battery and store it in a cool, dry place separate from the sprayer. Store the unit away from direct sunlight and extreme temperatures.
