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

Re: Is this correct to say ?
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

kwh determines your range, its like your gas tank.dineshmdes wrote: ↑Mar 15 2019 9:47amThanks a lot for the reply.

Voltage is your speed. I recently went from 10S which is 36V to 15S which is 62V and the speed difference is pretty drastic. I did 15S purely because of my Dell laptop chargers, which all spit out 20.50V, yes I have three of them because I have three sections of 5S in series. The capacity should be 16Ah, but it is no where near that these days, I would say I have lost 75% of the over-all capacity, so I can only use 25% which gets me about 12km before I have to recharge. Which is pretty do-able for now. I would say that the actual capacity now is 3.5-4Ah out of the total 16Ah. I am moving up to a brand new pack, of 25R's and 12.5Ah and 15S. The LVC is set too low so I have to open up the controller and find the resistors for the LVC, I may do a shunt mod on the controller to get more amps out of it, since I have a few non-working controllers. An enthusiast will usually have 2 digital multi-meters, a spare controller, spare throttles and a broken controller, along with a few wire strippers for good measure, a soldering iron with a coil wire stand. In case something goes wrong, gotta be able to swap things out.
