Hi Guys!

I'm new in this forum and I'm a greenkeeper, it means that you can ask me everything about grass, flowers and trees but I have ZERO knowledge in electrical systems. This is why I'm asking here if someone with good patience and really helpful can help an ignorant gardener with some basics.

I would like to test the feasibility of a project, try to substitute a classical endothermic engine with an electric motor:

The actual engine produce 3,2 kW at 4000 rpm and this engine has to work at least 4 hour in a row at the max speed and my question is: If we suppose that I've already a DC electric motor that develops 3,2kW, how can I calculate the dimension and the charateristics of the battery pack to have this power constantly for at least 4 hour?

Which is the right balance between volts and ampere to obtain 3200 Watt? how can I decide this ratio and how can I know if it makes sense in the reality?

sorry if maybe it's a too stupid question but I hope someone can give me a hand!
