I can not tell you my exact calculations...but I played with some of them to try and figure out how many 18650 cells I would need

the basic formulas are simple:

voltage per cell X number of Cells in Series = Volts

ah rating per cell X number of Cells in Parallel = Amp hours

next:

Volts X Amp hours = Watt hours

...as I understand it: "Volts" is how quickly the electricity can work(with a battery, the voltage will vary with the state of charge; a normal 3.7v cell might be fully charged as high as 4.2v, and drained at 3v) fast(high voltage) or slow(low voltage) frequency, no matter how much its actually doing at once...kinda likespinning away crazy if without any amps

then:

"Amp hours" is the amp level a battery can output if it was drained during one full hour of time; with battery storage, 'time' is the key factor, and 'amp hours' are different than a single momentary 'amp' load, and you could use it faster than a hour and get more amps all at once(so like it could be 3amp load for an hour, or 6amp load for a ½hour, or 12amps load 15min. etc) so how much the electricity can actually do no matter how fast or slow it does it, all at once or spread out over a longer time...kinda likesitting there doing nothing if without volts

so:

"Watt Hours" is the total capacity of the battery pack...it can be high amp hours with low volts, or low amp hours with high volts and still be the same(so like digging slow with a shovel, or digging fast with a spoon...but still digging the same size hole in the same time)

...there is also "current" which might be how fast and how much a battery pack can flow its power; like high current to a motor could suck a battery dry quickly and give you lots of motion power to move mass far and fast, but low current flow and you are barely moving anything or anywhere slowly with long battery life; the job of the 'controller' between the battery and motor

and:

"Series" battery cell connection is when they are lined up end to end with the + on one going to the - of the next

"Parallel" connection is when the battery cells are all next to each other, with all the + ends together but separated from the - ends wired together

finally:

number of Cells in Series X number of Cells in Parallel = total number of Cells in the battery pack

...but when I was looking to do 100kph for 100km, the 18650 cells seemed to be the only battery pack that would do that with keeping the weight and size of the bike down

(I was trying for around a low 100kg motorcycle weight, with 100v X 100ah = 10kWh battery pack)

you should be able to build an el.motorcycle that would reach a max speed of 100kph

-or-

an el.motorcycle that can go 100km distance

...either of those might be pretty easy...but building one that can doboth at the same time(run for one hour @ 100kph for 100km) and you will need to have everything in 'perfect balance'! [weight, size, aero, power, battery]

so there might be other sacrifices(like you might need something more aerodynamic than a supermotard, you might not have lower speed performance, and you might have to use a smaller motor with lower weight)

good luck

...and I will be watching to see if other forum members know how to do it! and help you
