I ordered an extra battery with it as I was worried that one was not enough but so far one has easily lasted for hours at a time. I have only had it out a half dozen times so will know more about longevity as I test it.

Charging the battery is most likely from a 220 volt network or can 12 volts?

It charges on a regular wall outlet and pumps out 36V to its electric engine.

Oh yeah, then there's no problem, otherwise I thought he needed special equipment. Congratulations on your excellent purchase :)

@greenman. Am just curious. Do you make car engines?

No. The company doing the conversion is: www.kuksshop.com

I wonder what fuel consumption this engine has for 100 km?

Has not been driven 100 km to know as of yet.

Are engined gauged with fuel consumption status per kilometer?

Typically, fuel consumption is measured in liters per 100 km, at 1 km of such have not yet heard :)

Ok
