Overview

The Blue Sea Systems 7517 is a remote battery charger display for P12 battery chargers that can also show voltage for up to three battery banks on its own. When it is connected to a P12 charger, the screen can show charger summary data including voltage, charging current, charging stage, and faults in plain language.

The display runs on 6 to 36V DC, reads one to three battery inputs with a common reference, and uses a 55 x 28 mm yellow OLED screen that stays readable in daylight. It will also keep showing bank voltage bar graphs when AC power is not present, so you still get a quick check of battery status at the panel.

Key features

• Monitors voltage on 1 to 3 battery banks and detects the number of banks automatically.
• Shows the P12 charger summary screen with voltage, charging current, charging stage, and charger faults when linked to a P12 charger.
• Accepts 6 to 36V DC input and includes reverse polarity protection.
• Yellow OLED display area measures 55 x 28 mm and remains readable in daylight.
• Dip-switch setup selects voltage bar graphs or charger summary view.
• Continues to show voltage bar graphs even when AC power is not present.
• Optional standby mode shuts the screen off after 4 hours, and the built-in knock sensor wakes it back up.
• Built as a drop-in replacement for traditional rectangular displays.

Compatibility and fit

This display is meant for boats using a Blue Sea Systems P12 charger and needing charger information away from the charger itself. It also works as a straightforward battery voltage display when no P12 charger is connected, which is useful for house, start, and auxiliary bank monitoring from one panel location.

It suits refits where panel space is already cut for a rectangular remote monitor. It is a good match for cruisers, pilothouse boats, and workboats where the charger is mounted out of sight but battery status still needs to be checked quickly.

Installation and setup

Screen selection is handled by dip switches, letting the display show voltage bar graphs or the P12 charger summary screen. The included 25 ft Cat5e cable gives room to mount the display at a helm, nav station, or cabin electrical panel while the charger stays in a separate compartment.

Current draw is up to 50 mA in normal use, and standby mode drops draw to less than 1 mA after 4 hours of inactivity. A tap on the unit wakes the display through the built-in knock sensor, which is useful when the monitor is mounted flush in a panel.
