Guest 2731A On-Board Battery Charger, 30 Amp 12V 3-Bank, 120V Input

The Guest 2731A is a 30 amp, 12 volt on-board battery charger built for 3-bank charging from a 120 volt AC input. It provides dedicated battery charging, sensing, and control for each of its three banks, so each connected battery gets its own regulated charge rather than a single shared output. The charger is designed for all 12 volt flooded and AGM lead acid batteries, making it a versatile choice for boats running multiple battery banks for house, starting, and accessory loads.

Built-in protection circuitry guards against reverse polarity, over-current, over-voltage, over-temperature, and includes ignition protection, while in-line fuses add further DC wire protection. The housing is fully waterproof to an IP67 rating and shock resistant, so the Guest 2731A can be mounted in exposed engine compartments or bilge areas and used in both fresh and saltwater environments. The unit measures 14 inches deep by 11 inches wide by 10 inches high and weighs 11.1 pounds. It ships as a complete kit with the battery charger and AC/DC power cables, and is backed by a 2 year warranty.
