Dramm Back Pack Sprayer with Lithium Ion Battery - 4gal - 150psi

Dramm BP-4 Lithium Ion Backpack Sprayer 4gal 150psi - Battery Power, Professional Performance

The Dramm BP-4 Backpack Sprayer is a rechargeable lithium ion battery-powered sprayer built for professional cultivation applications. Operating at up to 150psi, the BP-4 atomizes spray solutions into fine, consistent droplets for excellent coverage and penetration on foliar targets. The battery-operated pump maintains even flow rates throughout the application, eliminating the pressure fluctuations common with manual pump sprayers. The 4-gallon capacity hits the sweet spot for extended spot treatment and concentrated application runs, and the quick-change battery system minimizes downtime between charges. Operating time on a single battery is approximately 45 minutes. Package includes battery and quick charger.

Key Features & Benefits

• 150psi maximum operating pressure: High-pressure atomization produces finer droplets for superior coverage, penetration into dense canopies, and better chemical distribution on foliar targets.
• Battery-powered even flow: Electric pump maintains consistent pressure and flow rate throughout the tank - no pumping variation that could cause uneven application coverage.
• Quick-change lithium ion battery: Fast battery swap allows continuous operation with a spare battery, minimizing downtime between applications.
• 4-gallon capacity: Large enough for extended application runs while remaining comfortable to carry on the back throughout the session.
• 45-minute runtime per battery: Provides coverage for significant growing areas on a single charge; spare batteries extend runtime for larger operations.

Who Should Use This

The Dramm BP-4 is designed for commercial cultivators, IPM technicians, and greenhouse operators who need consistent, high-pressure spray coverage without the fatigue of manual pumping or the logistics of a cart-mounted unit. It is particularly effective for applications requiring fine atomization - foliar pesticide and fungicide treatments, PGR applications, and targeted spot treatments where coverage uniformity is critical.

Compatibility

Compatible with pesticides, fungicides, fertilizers, and other liquid spray solutions compatible with the tank material. Confirm chemical compatibility before use. Battery and quick charger included. Spare batteries available separately for extended operation.

Frequently Asked Questions

How long does the battery last per charge?

Operating time is approximately 45 minutes per battery under normal use conditions. Actual runtime may vary depending on operating pressure setting and ambient temperature.

How does 150psi compare to a standard manual backpack sprayer?

Manual pump backpack sprayers typically operate at 40-60psi. The BP-4's 150psi maximum produces significantly finer droplet atomization, improving coverage uniformity, canopy penetration, and chemical adhesion on foliar surfaces.

Does the package include a charger?

Yes. The BP-4 package includes the quick-change lithium ion battery and a quick charger for fast turnaround between applications.

Can I use spare batteries to extend runtime?

Yes. The quick-change battery design accommodates spare batteries for uninterrupted operation on large applications. Spare batteries are available from Dramm.
