Balwaan BS-30GL Gold Series Battery Sprayer Machine - Li-ion Double Motor Sprayer

The BS-30GL is Balwaan's Gold Series battery sprayer, built around a 12V x 12A lithium-ion battery and a twin motor setup. It holds 20 litres, works at an average pressure of 130 psi, and weighs 5.56 kg empty. A single switch moves it between single and double motor, so you decide whether the job needs more pressure or more hours.

What This High Pressure Battery Sprayer Machine Is Built For

This is a crop protection sprayer first. It handles pesticides, water-soluble fertilisers and herbicides across farming, gardening and sanitisation work. Running both motors together delivers up to 3X the pressure of a single-motor unit, which is what carries spray to the top of a standing crop instead of dropping it at knee height. Water flow runs between 1.8 and 3.3 litres per minute depending on the nozzle fitted.

Double Motor Battery Sprayer Powered by a Li-ion Battery

Both motors run on one battery. Use double motor when you need pressure and reach, single motor when you need the charge to last a full day. The switch sits under a protective cover, so it does not trip on its own while the tank is on your back.

12V Li-ion Battery vs Traditional Lead-Acid Batteries

The two battery types differ on four points that matter once you are carrying the tank.

If you would rather stay with a lead-acid unit, the BS-30G Gold Series sprayer uses the same 20 litre body.

20 Litre Tank Capacity for Extended Spraying Sessions

Twenty litres is the standard knapsack size, and it is the reason this 20 litre battery sprayer suits field work rather than pot-to-pot garden use. At 1.8 to 3.3 litres a minute, one full tank covers a long stretch before you walk back to refill. Run the single motor and the charge holds for 6.5 hours, which is a working day for most operators.

Where to Use This Battery Sprayer Machine

Balwaan lists this 12V battery sprayer for agriculture, horticulture, household and industrial spraying. In practice that means standing crops, vegetable beds, orchards and nurseries, plus sanitisation work around sheds, godowns and premises. For a smaller garden job where 20 litres is more than you need, the SP-80B Li-ion sprayer carries 8 litres in the same battery format.

Comfort and Control Features for All-Day Spraying

A loaded 20 litre tank weighs over 25 kg on your back, so the carrying hardware matters as much as the motor.

• Extra padded cushion belt spreads the load across both shoulders

• Lower back cushion sits between the tank and your spine

• Smart filter clutch keeps grit out of the pump line

• Steel lock delivery pipe holds its connection under pressure

• On-off switch cover protection stops accidental starts

• Removable battery, so the pack charges separately from the tank
