I recently bought a 500 watt, 36 volt rear wheel drive (26" wheel, w/7 speed sprocket) kit that I expect to be delivered in the next week.
500 watts @ 36 volts is 13.88 amps load. I'm considering assembling a battery consisting of 10 series banks of 3 cells parallel of 18650 lithium ion cells. (a total of 30 cells)
My question is: I see cells rated for constant discharge rates of 5, 10, 15, 20 etc. amps however...
It appears to me (absolute newbie here) that if I have 30 cells and the total draw/load is13.88 amps, then the sustainable discharge rate required per cell would be 13.88/30, or .46 amps per cell. If that is correct, then there is no point in buying high rated discharge (expensive) cells.
maybe i'm missing something.
