maximum capacity. A 1C rate means that the discharge current will discharge the entire battery in 1 hour. For a battery with a capacity of 100 Amp-hrs, this equates to a discharge current of 100 Amps. A 5C rate for this battery would be 500 Amps, and a C/2 rate would be 50 Amps. Similarly, an E-rate describes the discharge power.

current limiting a shorted load to 20A
In case of a short-circuit the battery''s 12V(?) will be over the switching MOSFETs and even with a 20A current limiter they will have to deal with 240W(!). There are tricks for foldback current limiters, which reduce the current to a safer level after a short-circuit, but my idea is that it''s best to cut off completely.
