1. How many watt hours and what configure or choices are people running out there? I am hoping for 90v 15ah drawing around 8kw
To me there's no point buying this or that controller or motor if I don't know if I can feed it well.
Hello John,
The choice of the battery pack is personal. It depends what you would like to do with your ebike. If you are planning to buy an adaptto controller is good not to exceed the suggested voltage by adaptto that is 85V, so no more than a 22s battery pack. I think it's better to buy a battery pack made by 18650 cells (it will be lighter and will last longer), many guys here can build a very well made pack for you or you can build it by your self if you read the battery threats.
1.5kwh of energy is a small battery for me with 8.000W of peak power you will be able to cover maximum 35km of distance. If you want to go further you need 2-2.5kWh pack.
As I said from the beginning it's personal, some ebikers prefer a lighter ebike and to ride it only for 30-40 minutes.
there is a guy here with the name offroader, he has managed to fit 3KWh battery pack into this frame!
