Battery Banks & Over-Current Protection

A single 100Ah Group 31 Odyssey AGM battery can deliver 5000A of short circuit current into a dead short. A 200Ah bank of Group 31 Odyssey AGM batteries is 10,000A into a dead short. This is why the AIC rating of the over-current device is critically important.

The science behind battery short circuit

A battery''s maximum short circuit current depends on various factors, including the battery''s chemistry, size, and internal resistance. The larger the battery, the higher its short circuit current. For example, a car battery can have a short circuit current of several hundred amps, while a small button cell battery may only have a few milliamps.
