VEVOR Deep Well Submersible Pump, 1HP 115V/60Hz, 37gpm Flow 207ft Head, with 33ft Electric Cord, 4\" Stainless Steel Water Pump for Industrial, Irrigation&Home Use, IP68 Waterproof Grade

Depends on what you're doing with it. If you're trying to use it for the house, yes, you need a control box. If you're using it strictly for manual irrigation all you need is a standard switch to turn it on and off when needed.

The working current is 12.1A.

Hello, yes, the water can flow back to the pump when the pump is off. (The water outlet of the normal water pump is higher than the pool or other water storage containers. After the pump is turned off, the water in the pool will not flow back into the deep well. A check valve is installed at the water outlet of the pump so that the water will not flow back to the deep well)

Hello, it can be used directly by connecting the battery board. From your description, it can meet that requirement. I hope it can help you, thank you!

If plugged into a power source, the pump will not stop cycling when the water is disconnected.
