You should have gotten a wire diagram with the controllers you purchased.
Size of battery in terms of voltage, amp-hour and amps depends on your controllers voltage rating and be sure your battery amps are less then the controllers amps, and ah is just how far you can ride. Power is voltage x amps = watts, so if you have to little watts you wont have lots of power to get up a hill. 36Vx10A = 360W which is quite wimpy but 36V x 40A = 1440W which is lots of power to get up hills. 36V is slower speed compared to 48V.

Markz
Thank you for your response. Unfortunetly like reading chinese to me!
Way over my head. I asked for a diagram but got photos of wire mess!
What should I look for on controller?
If I start with the two hub wheels I can buy controllers here in US maybe.
What size battery should I be looking for?
Do you know good places to buy?
Is there something off wheels that would help you tell me where to start?
Thanks
Steve

What does "good run time" mean to you? 1hr, 2hrs, 8hrs? Where will you be running it (on/off road, mud, hills, snow, etc.)? Also how much load (single person? multiple people? how much does the scooter weigh)?

For the wiring, there are probably others who can help better than me, but you could start by uploading the "photos of wire mess" that you received to see if we can help interpret them. Also links to what you have would also be helpful. The more details you provide, the better help people can provide.
