I don't understand how somebody making a statement about mounting three of these on a scooter is not flagged as off-topic, but me asking a question about how whether that many of these cells would actually work for that purpose is flagged as off-topic, but fair enough. Thank you for the advice...

Trying to get an idea of how many modules I'd need for different sized vehicles... These are 20Ah per cell at 3.3V, right? So in 7s3p configuration, you'd get 3.3V * 7 = 23.1V for 20Ah * 3 = 60Ah per module? So with three modules connected in parallel you'd get 23.1V, 180Ah or for three modules...

There's space where the original engine is (minus space for an electric motor), and there's space underneath the seat where the muffler is. I think there's plenty of room for batteries.

I want to e-convert a Sachs MadAss (a small, light scooter-like motorcycle) to have good pickup, and a top speed of say 65 MPH while operating well at 35 MPH. Roughly what size electric motor will I need (in terms of power output and voltage), and what are the battery tradeoffs I should worry...

I'm a n00b to e-converting motorbikes, but I don't want to miss out on the chance to capitalize on A123's misfortunes. Can somebody please answer a few ultra-basic questions about these? -- What is the XsYp notation for batteries? -- If I want to e-convert a Sachs MadAss (small, light...
