Is it correct to say that :
If 2KWh (72V-28Ah) gives me a range of 100 Km and 60 Kmph Top Speed (2KW Motor@72V).
Then 1KWh (72V-14.4Ah) will give me a range of 60 Km and 60 Kmph Top Speed (2KW Motor@72V)..

That means the range approx. reduces to half with the same motor and top speed.
Please help.

Thanks
 
Yes, as long as the half-sized battery has the same internal resistance ( and thus double the load doesn't double the voltage sag )

IE.. the 2kwhr battery is 2C capable and the 1kwhr battery is 4C capable.. therefore the efficiency which the battery delivers power to the controller is unchanged..
 
Thanks a lot for the reply.

Can I say that if I have a controller along with this 2Kw motor @ 72V.

A
2Kwh with a 3C
1Kwh with a 3C

Both will work on the same motor with variation on speed and range, without affecting the circuit.
Sorry, I might sound dump :(
