What Is The BWT Watering System 18 Cell 36 Volt?

The BWT Watering System 18 Cell 36 Volt is a lithium-ion battery-powered irrigation solution designed for high-efficiency water delivery. Its 36V configuration (18 cells in series) supports pumps with flow rates up to 1,800+ liters/hour, optimized for agricultural or landscaping applications. REDLINK™-style smart protection automatically stops operation during dry runs, while modular battery compatibility enables extended runtime with swappable 36V packs. Pro Tip: Pair with 19mm inner-diameter hoses to maximize flow rates and minimize energy waste.

How does the 18-cell configuration enhance performance?

Serial voltage stacking in the 18-cell architecture achieves 36V output, doubling torque and flow capacity compared to 18V systems. This enables 22-meter head heights for elevated irrigation while maintaining lithium-ion advantages like 500+ charge cycles and 30% lighter weight than lead-acid alternatives.

By arranging 18 LiFePO4 cells in series, the system delivers stable voltage under heavy loads—critical for diaphragm pumps requiring sustained 800W+ output. For example, irrigating a 0.5-hectare vineyard would typically drain a 10Ah 36V battery in 90 minutes, but quick-swap cells allow continuous operation. Pro Tip: Always balance cells monthly using a 36V-specific charger to prevent capacity drift. What happens if you mix old and new cells? Imbalanced discharge rates can trigger premature shutdowns, so replace all cells simultaneously.

What pump specifications pair with this system?

The 36V brushless motor typically drives centrifugal or diaphragm pumps producing 25-30psi, sufficient for sprinkler systems and drip irrigation. Key specs include ¾” BSPT threaded ports and thermal cutoff at 65°C to prevent winding damage during prolonged use.

How does smart protection improve reliability?

Integrated current sensors and dry-run prevention algorithms shut down the pump if flow rates drop below 2L/min for 30 seconds. This protects seals and impellers from cavitation damage—a common failure point in solar pumps lacking voltage regulation.

FAQs

Can I use third-party batteries?

Want OEM lithium forklift batteries at wholesale prices? Check here.

Not recommended—BWT systems often employ proprietary voltage curves. Generic packs may underperform or void warranties.

What’s the runtime per charge?

6-8 hours with a 15Ah battery at 50% load (e.g., powering three 360° misting nozzles simultaneously).
