Guest 10A 12V 2 Bank On Board Battery Charger

The Guest 10A 2-Bank On-Board Battery Charger handles two 12V banks, each with its own charging, sensing and control circuit, in a fully sealed housing.

High-frequency digital charging is what allows this generation of Guest chargers to be considerably lighter than the transformer-based units they replace, without giving up output. Weight matters on something bolted inside a locker or under a console, where a heavy charger needs a substantial mount and puts load in an awkward place.

Two independent circuits mean the charger reads and treats each battery separately rather than averaging across a combined bank, so a tired battery does not drag a healthy one down. Five-stage automatic charging covers recovery, conditioning and maintenance without switching modes as battery condition changes.

The expanded LED display shows each bank separately, and wiring and battery-fault detection flags connection problems or battery conditions needing attention. Energy-saving maintenance mode cuts consumption once charging finishes, and the charger is pre-wired to simplify installation. Explore more on-board battery chargers.
