The battery adapter works for 18V M18 Li-ion battery 48-11-1815, 48-11-1850, 48-11-1820, 48-11-1840, 48-11-1815 and more. Installed with two 12 gauge wire and the maximum permissible current is 55.6A Input Voltage 14.4V ~ 21V, Output Voltage DC 12V, Output Current: 15A , Output Power: 180W; The Maximum conversion efficiency is up to 95% with the Synchronous Rectification Technology; Made of high quality material, waterproof, anti-dust, anti-shock and better heat dissipation We creatively combine the battery adapter and the voltage converter with 2 heat-resistant wires already, making it more easy to use. Just install the battery to the battery adapter and then connect the voltage converter to your device Battery Adapter: The fuse supply overpowers protection. The copper contact improves the conductivity and safety; Voltage Regulator: Equipped with smart chip, features Over-current, Over-load, Low-load, Short-circuit, Over-heat,over drain, and anti low voltage protection WIDE APPLICATION: Widely used for golf cart, motor, railway signals, car display screen, GPS, speaker, instruments, DVD, surveillance system, solar energy, photo-voltaic power, led strip light, power wheel, cable TV, 3D Printer, ham radio transceiver, and etc color:Red Material:ABS Package Contents: 1 x Power Wheels Adapter Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
