Balwaan BS-22D Double Motor Battery Sprayer - 12V, 20 Litre, High Pressure

The BS-22D is Balwaan's double-motor knapsack sprayer, built around a 20 litre tank and a 12V x 12A lead-acid battery. Both motors run together to push 160 PSI, which is what carries spray to the top of a standing crop. A full charge covers 15 to 20 tank loads.

What Is the Balwaan Double Motor Battery Sprayer?

It is a rechargeable back-mounted sprayer for pesticides and fertilisers. Two motors instead of one means higher pressure and longer reach: up to 20 feet vertically and 30 feet horizontally. Water flows at 9 litres a minute, and the tank sits in a high-density virgin plastic body. At 6.56 kg empty, it is a knapsack, not a trolley, so a single operator carries and works it.

Where to Use This Agricultural Battery Sprayer

Standing crops are the main job: pesticide over wheat, paddy, cotton and vegetables, and water-soluble fertiliser through the season. The 30-foot horizontal reach also suits orchard rows and boundary hedges where you cannot walk the sprayer close in. Beyond the field, it handles nursery beds, polyhouses and sanitisation work around sheds and godowns. For jobs too small to justify strapping on 20 litres, a manual sprayer is quicker to fill and empty.

1. Charge fully before first use, and recharge after every spraying day rather than leaving the battery flat.

2. Rinse the tank with clean water after every chemical, and run clean water through the lance and nozzle until it sprays clear.

3. Remove and clean the tank filter weekly. Grit in the line is the most common cause of pressure loss.

4. Store with the tank empty and the cap loose, out of direct sun.

5. Follow the chemical label and your local agriculture department guidance on protective gear, spray drift and re-entry timing.

Benefits of a High-Pressure Battery Sprayer for Everyday Farming

A double motor sprayer lets you cover more crop per charge and spray without pumping by hand.

• Finish a full day's spraying on one charge, since 15 to 20 tanks covers most holdings

• Spray tall crops from the ground, as 160 PSI carries to 20 feet without you climbing or reaching

• Waste less chemical, because steady pressure holds droplet size even as the tank empties

• Work longer before your arms tire, with no lever to pump and only the lance to aim

• Empty a tank at walking pace at 9 litres a minute, so you keep moving down the row

• Start the next day fully charged, as a 5 to 6 hour charge runs overnight
