Marinco 2720A ChargePro Onboard Battery Charger, 20 Amp, 2 Bank, 12V/24V

The Marinco 2720A ChargePro is an onboard marine battery charger built for boats running either 12 volt or 24 volt systems. It delivers 20 amps of charging current split across two independent battery banks, so each bank is monitored and charged on its own rather than sharing a single output. The charger accepts a 120 volt AC input, making it suitable for shore power or onboard generator hookup.

Housed in a sealed, IP67 waterproof enclosure, the 2720A is designed to withstand the moisture, spray, and vibration typical of a marine engine compartment or battery locker. Built-in protection circuitry guards against reverse polarity, over-current, over-voltage, and over-temperature conditions, and the unit is ignition protected for safe installation near fuel systems. It connects using ring terminal/eyelet connectors and is compatible with both flooded and AGM lead-acid batteries, giving boat owners flexibility in battery chemistry without needing a separate charger for each bank.
