So you're looking at the 20L class drones for your spraying season—we've had a few other buyers come through recently asking about the same capacity range, and honestly the AL4-20L handles heavier workloads pretty well, though it's not really built for small backyard plots or anything under a couple of acres.
It weighs about 24kg empty, but with a full 20L tank you're pushing max takeoff weight near 55kg, and what it does is give you roughly 9 to 12 hectares per hour depending on your speed and nozzle settings—the 8 high-presure nozzles spray a 7 to 9 meter width, and the flow rate sits at 3.5 to 4 liters per minute, which is better than some older models we've seen for coverage uniformity.
Flight time is short—10 minutes per charge, that's pretty much the reality with a 14S 22000mAh smart battery, so you'll want at least two or three packs if you're running a full day, and the 3000W 60A charger can bring one back up in about 20 minutes or so (usually 2-4 weeks lead time on extra batteries, but we keep some in stock).
Most buyers go with the standdard autonomous flight features—AB point navigation, obstacle avoidance, and a 1500m control radius—but our company can do basic OEM branding on the body if your order hits a certain volume, and the warranty runs 3 to 26 months depending on the component, which is something people don't always ask about upfront.
Anyway, the folded size is 955x640x630mm, and the shiping crate comes in at 1460x770x900mm with a gross weight of 85kg, so you'll need a pallet or a van, and bulk pricing kicks in around 10 units—lead time is typically 30 days give or take, but we usually have stock for smaller orders, just confirm before you commit.
It's CE, FCC, RoHS, and ISO9001 certified, and while it handles pesticides and fertilizers fine, we don't recommend it for anything with high viscosity or sticky granules—the nozzles clog easily if you're not rinsing between fills, something we learned form early field tests.
The MOQ is typically 1 unit for stock models, but we can discuss larger orders if you need a fleet. Just let us know the quantity and timeline.
Lead time is usually 7-15 working days after order confirmation, depending on stock levels and your location. We'll confirm exactly when you place the order.
Yes, all those certifications come standard with every AL4-20L unit. We'll include the documents in the shipment or send them digitally beforehand if you need them for customs or compliance.
The drone comes with one 14S 22000mAh smart battery and a 3000W 60A smart charger. The battery gives about 10 minutes of flight time per charge, and the charger refills it quickly.
We can adjust the nozzle type or spray flow rate for different chemicals, and the 20L tank handles most pesticides and fertilizers. For major customizations like frame size or flight controller, we'd need to discuss minimum order quantities and lead times.
