The Aqua Sub XTREME™ is an AC/DC powered watering cart. The cart is powered by a 12-volt battery (included) with its own on-board charger. The battery’s state of charge is indicated by LED lights and the pump will automatically shut off if the battery is low. AC power can be used to either power the cart or charge the battery. The new cart features a space-saving upright design that is easy to maneuver. The translucent tank allows monitoring of the water level while in use.
