I'm not sure what you mean. Current limiting is a thing done by ESC not batteries in fighting robots normally.

For the current the battery can safely provide it's the capacity x discharge rating (8.4Ah x 30 = 250A). Batteries being drawn over that will be damaged.

Also lastly... dear god Zippy LiFe packs are absolute rubbish. They die at the slightest hint of use. They were in Nuts for robotwars and of the 8 we took only 2 are still alive.
