Hi,
Just waiting for my motor to come by.
1) Please confirm my pack design
2) Please suggest optimizations (design/ cell technology)
Hub nominal rating: 144V 120A
Be X the voltage of my cells when full.
Be Y their Ah when full.
Be Z their max discharge amperage.
I may go for LifePo4 (IFR) 18650 cells.
Should I maximize the nominal output of my motor, please confirm the design of my battery pack:
Serie connections:
144 / X.
If X = 4 -> 144 / 4 = 36.
Parallel:
120/ Z.
If Z = 10 -> 120 / 10 = 12 cells.
If Y = 1.2 -> 12 * 1.2 = 14.4Ah ( 14.4 / 120 x 60= 7min of use)
So, I am good for a 36S12P pack, or (36 * 12) = 432 cells ($$).
That seems like a lot of cells to me.
Math correct? Which technology would you recommend?
