Default RE: Cyclone battery size?

A 2400 mAh battery rated at 20C can provide a maximum current of:

2.4 x 20 = 48 Amps (not enough if you need 54 or 58 A)

A 3400 mAh battery rated at 20C can provide a maximum current of:

3.4 x 20 = 68 Amps (possibly enough; see below)

It is important to note that the C rating of batteries is often measured by battery makers under ideal conditions that are not representative of the conditions under which we use the batteries. To give yourself a safety margin, it may be a good idea to discount the claimed C ratings somewhat. Some RCers use 80% of the claimed C ratings.
