Guest On-Board 15-Amp 3-Bank Battery Charger

Description

The Guest On-Board 15A 3-Bank Battery Charger provides independent charging and monitoring for three 12V battery banks. It is designed for boats with multiple starting, trolling, or accessory batteries that need one sealed onboard charger for routine charging and maintenance.

Each bank receives dedicated charging, sensing, and control through Guest’s five-stage digital charging system. The expanded LED status monitor makes it easy to follow the charging process, while wiring and battery-fault detection help identify problems before they become harder to diagnose.

The IP67 waterproof and shock-resistant enclosure is suitable for fresh- and saltwater applications. Built-in safety protection includes reverse polarity, over-current, over-voltage, over-temperature, and ignition protection, with in-line fuses protecting the DC leads. The charger is prewired for easier installation and supports flooded and AGM 12V lead-acid batteries. For three-bank marine systems needing dependable sealed charging, the Guest 15A charger provides independent control across all three outputs. Look through the rest of our on-board battery chargers.
