What provides the power to start a small craft?

The correct answer indicates that two high power 12V DC batteries are typically used to start a small craft. This is due to the need for sufficient power to ensure reliable starting of the engine, particularly in marine applications where the starting conditions can be more demanding than in automotive contexts. Using two high power batteries provides the necessary cranking amps that facilitate a strong ignition, particularly in cooler temperatures or when the engine is operating under load.

High power batteries can deliver a larger surge of current, which is essential for overcoming the initial resistance when starting an engine. This configuration helps ensure that the engine starts effectively, even in challenging conditions. Additionally, the use of two batteries can provide redundancy; if one battery fails, the other can still function, which is critical for safety in marine operations.

While a single 12V DC battery could power some smaller engines or systems, it may not provide the reliability and power needed for larger or more demanding engines.

A setup of two regular 6V batteries in series would yield 12V, but the overall power capability might not match that of high power 12V batteries, especially for cranking applications. Similarly, a 24V battery bank is typically more suited for larger vessels or specific systems rather than small
