I'm still maturing my idea about a light and fast ebike.
Now thinking about maybe having a Dahon speed (20'' wheel) with a bafang 48V500W and 2 NiCoMn 48V10AH:

The problem with NiCoMn is its low C rate. For optimal battery life, discharge should be around 1C. So to keep the C low, the voltage has to be higher. I was thinking about putting these 2 batteries in series so I would have a 96V10AH total battery pack at 5.6KG!!! (as light as lipo but safer and with 800 cycles)
With this configuration, I should be able to reach 25-30 mph without drawing more than 10-20 AH with a 20'' wheel. But the question is... Will the Bafang at 48V500W be able to handle that? Voltage is double and I'd probably reach 1500W at 15AH.
