About this item

• ⚙️ Designed Specifically for Harpy Eagle Oil Extractor Pump: This battery adapter was custom-built to convert the Harpy Eagle Oil Change Extractor Pump into a fully portable device. With this kit, you're no longer tied to your vehicle's 12V battery — perform oil changes anywhere, even in hard-to-reach areas like gearboxes, rear axles, and lawn mowers.
• 📦 Complete Connection Kit – No Soldering Required: The package includes everything you need: pre-wired adapter, WAGO lever connectors, inline fuse housing (30A), spare fuses, and high-conductivity 12 AWG wire. Installation takes under 10 minutes and requires only a wire cutter — no crimping, splicing, or soldering tools necessary.
• 🛠 Step-by-Step Setup Instructions Built In: To install, cut the pump’s original power cable 4–6 inches from the motor. Strip 1.5 inches of the outer insulation and 0.38 inch (9–10mm) of the red and black wires on both ends. Then connect matching wires using the included WAGO connectors (red to red, black to black). Once connected, insert a fully charged Milwaukee M18 battery — and the pump is ready for cordless use.
• 🔋 Built for High-Current Operation with Safety First: Equipped with a pre-installed 30A fuse and two spares, this adapter handles high-power draw with confidence. The heat-resistant ABS housing, waterproof fuse cap, and 12AWG silicone copper wire ensure safe use in garages, driveways, or outdoor conditions. Use in 10 min ON / 10 min OFF cycles to protect both pump and battery.
• 🔌 Compatible with Milwaukee M18 18V Lithium Batteries: Tested with models 48-11-1815, 48-11-1820, 48-11-1828, 48-11-1840, 48-11-1850, 48-11-1860, and more. Secure fit ensures battery won’t wiggle or disconnect during operation. Adapter includes mounting holes for optional fixed installation on a wall or tool board.
• 🧠 Helpful Usage Notes for Safe Operation: This adapter is not a charger and simply transmits battery voltage directly to the pump. Always connect red wires to red terminals (positive +) and black wires to black terminals (negative –) using the included WAGO connectors. After each use, remove the battery to prevent unnecessary discharge. For optimal performance and safety, operate the pump in 10-minute work intervals followed by 10 minutes of cooling.
