My landscape Friend had a 12v setup with full sized battery prior to this she wasn't all that happy with. Finds this much more convenient with the small rechargeable M18 batteries. Her pump is solid mounted on the trailer with a couple of large SS hose clamps on a small platform.
Mine has totally replaced using a pull start 3.5 hp gas powered Pacer water pump for my work. That was my main power source to move water for years. Was very cumbersome to haul it around back and forth to the job every week and took up a lot room in my vehicle plus needed fuel and engine oil and other maintenance.
Now I just push a button
And as long as I leave my hoses at the worksite the pump/battery itself is so small I can now transport it on my motorcycle as it easily fits in my rear luggage rack bag and that is pretty cool.
