Power Tool Corded to Cordless

Hi 'nstructables

I'm building a hovercraft (see several tutorials on Instructables - the one with a leaf blower) and my leaf blower is corded. I don't want to buy 25 miles of Black and Decker High Power Extension Cabling so I'm planning to convert to cordless.
Here's my idea: (in visual)

Is there anything I need to add? And if so, how do I make the "12VDC-240VAC" inverter described?

My blower is 1600 watt. Thanks for any help!

The biggest problem you are going to run into with this design is lifting the additional weight of the batteries. (Remember, the L in SLA is Lead!)

The cheapest/easiest way is to buy an inverter. 1600W / 240V = 6.6A, plus starting current so probably a 10A inverter would be about right. You can save a little money also because you don't need a "pure sinewave" inverter for a simple motor.

Alternatively, the leaf blower is most likely a universal motor, so instead of an inverter you can simply boost the DC voltage and run it off that. But again, by the time you got the circuit together, you might as well have used an off-the-shelf inverter.

Of course the easiest and most efficient solution of all is to use a gasoline or battery powered blower to begin with, but you probably already knew that. ;)

Thanks PS118!
So I just purchase a battery (probably not SLA :), a 10A modified sine wave inverter and my power tool is cordless?

Thank you so much, this is my first question on the forum!
