Description
The Mastervolt Charge Mate 2502 is a voltage-sensing split charge relay for boats and vehicles with a second battery. It connects the start and service batteries together while the engine or charger is running, so both batteries are charged, then automatically isolates them when discharging so the domestic loads cannot flatten the engine start battery.
The 2502 adds selectable operating modes: on, off, auto and start assist, the latter allowing the batteries to be combined to give extra cranking power. With a high 500 A current rating it suits larger small-craft installations while remaining compact and easy to fit. It works automatically on 12 V or 24 V systems.
