Batteries we are currently looking at are the elite 1500 which are rated at 10 for the C-rate.
Also, how would we know if a cell has gone bad inside a pack?
First - bad cell - either the pack will not come up to full voltage when charged or the voltage will sag badly under load. Bad cells might even kill the pack.
You can also tell you have a bad pack if you cycle it and it won't take full capacity of the charge. Cycling a battery pack is often a feature of the charger and you have to have a charge with a meter on it to know how much charge you put in. Cycling is a common practice to test a pack. If it cycles and takes less than 80% of its rated capacity it is considered bad.
Motors don't draw voltage they draw amperage. Read the first article (post 2) of the book. Title of the article is AMPS vs. VOLTS vs. C. Once you read that you will be able to answer you own question.
