It means that if your bank exceeds the CCA or Ah specification you'll need to default to the manufacturers "short circuit rating". Not too many even publish this rating. Odyssey does and each G-31 battery has 5000A of short circuit current. A 400Ah bank of four, in parallel, would be 20,000A..
If you can't find a short circuit rating
, then you need to default to a Class-T fuse which is has a 20,000A interrupt at 125V. The Class-T AIC rating will be much higher at 14V. Class-T is the only fuse recommended for LiFePO4...
