About the LockNLube® BTX System
The LockNLube® BTX Battery Transfer Pump System is built for professionals who need fast, portable, and reliable fluid handling. Its modular design lets you use the same Power Head across multiple containers and fluids, from 5 gal (20 L) pails to 55 gal (205 L) drums, covering everything from oil and ATF to coolant and DEF/UREA with a single motor.
Each BTX Starter Kit includes the rechargeable 18 V Power Head, reinforced transfer hose, and ergonomic dispensing gun for smooth, controlled flow. BTX Stem Kits add flexibility by letting you equip additional pails or drums for different fluids without buying another motor.
The BTX's sealed internal system prevents drips and cross-contamination, while integrated drain-back valves keep work areas clean and organized. Adjustable suction tubes reach deep into containers to get every last drop, reducing waste and cleanup time.
With flow rates up to 1.8 GPM (7.0 L/min) and runtime up to 53 gal (200 L) per charge, the BTX delivers performance equal to or better than corded or air-driven shop pumps—plus the convenience of cordless power. It's the cleanest, most versatile transfer solution in its class.
