Ok, hey guys,
Im interested in building a 36v 960w cyclone kit mid geared ebike. I want to use it for the daily ride to school for the next three years. That means that i'd need it to do the 11km trip there and back each day, ideally without the NEED to charge at school. So 25km range. I've read that the 960w Cyclone pulls around 40A continuous at WOT and can peak as high as 60a depending on your controller, and ideally i'd like to be able to do this trip at 50km/h continuous. From what i've read the 960 will push my 120 pound ass that fast easily, and ill be honest and say it's unlikely that i'll be pedalling accept off a dead stop (if it makes a huge difference in the long run). So my battery parameters are essentially 40-60 minutes of ~40a draw. I've read you really want to stay away from anything under 3c if you possibly can, so i guess around 30-40ah at 36v rated at 3c.
Now, at this stage i need to decide on a battery and a bms. I don't want to constantly fiddle with individual cells ongoingly, so i need the bms. I don't mind building my own battery out of cells. Research into what is availiable leads me all over the internet, seemingly with no one single definitive source of reliable information, so i come for aid! As far as i can tell, the thundersky cells could be configured for what i need but they seem heavy, as could the headway cells if they were availiable. I could go with a 20ah ping if i was cheap, but i really have read bad things and above all in this i seek to not be dissapointed by top speed or range... There is stuff availiable in the rc market as well, Turnigy...
So what should i get? What is most dependable over long term defined use of this sort?
Parameters:
Motor: 36v 960w Cyclone pulling ~40a continuous, 60a~ peak??? (someone confirm this with me, this is gathered information)
Bike: Norco Dirt jumper, 40 pounds
Rider: 120 pounds
Required Range: 25 km
Required average speed: 50km/h
Battery: Lightest for cheapest that will reliably do the voyage without sagging
Assumption: 36v 40ah LiPO4 rated at 3c~
What is everyones suggestion?
