So if you connect the battery backwards, it's essentially a short circuit. Why would it be connected that way? I thought diodes used as protection would be connected to stop the flow of electricity in a reversed polarity incident I think that you are correct. Reverse polarity produces great currents because of breakdown of semiconductors.
A reversed battery drags the gate above the source, blocking current flow by reverse-biasing the body diode. The current-sense amplifier, IC 2 , produces a small output current at pin 8 that is proportional to the current flowing between the RS+ and RS- terminals.
The diode allows current from a correctly installed battery to flow to the load and blocks current flow to a backward-installed battery. This solution has two major drawbacks: The diode must handle the full load current, and its forward voltage drop shortens the equipment's operating time.
Battery reverse polarity is the case when the source (for charging) or load cables are connected incorrectly i.e. source or load Negative to the Positive of battery and source or load Positive to the Negative terminal of the battery.
A variety of circuits can provide this assurance. The simplest form of battery-reversal protection is a diode in series with the positive supply line (Figure 1a). The diode allows current from a correctly installed battery to flow to the load and blocks current flow to a backward-installed battery.
In general, these batteries offer no mechanical means for preventing the reversal of one or more cells. For these systems, a designer must ensure that any flow of reverse current is low enough to avoid damaging the circuit or the battery. A variety of circuits can provide this assurance.
