The Multiple Battery Charging Module for 24V Trolling Motor Batteries with a Four Wire Plug (MBCM-24/4P) monitors the engine battery and when it reaches 13.5VDC it switches the trolling motor batteries from a series configuration (24VDC) to a parallel configuration (12VDC) and then connects them in parallel with the main battery to be charged by the alternator. When the engine is shut-off, both trolling motor batteries disconnect from the main battery, returns to a series wiring configuration.
In a two battery configuration (where the main battery is also used to power the trolling motor) the main battery is always connected to the alternator to absorb the charge current and the MBCM-24/4P re-connects the second battery from series to parallel configuration for charging.
The MBCM-24 is also available in a 2 wire plug and front mounted batteries (FB) with 18 feet cables. See MBCM-24/2P & MBCM-24/FB.
