Blue Sea Systems Triple Battery Bank Management Panel, 12/24V DC, 32V Max

Overview

The Blue Sea Systems Triple Battery Bank Management Panel is a battery switching and circuit protection panel for twin-engine boats using three battery banks. It combines two Dual Circuit Plus battery switches with push-button 24-hour circuit breakers and a 100A C-Series flat rocker circuit breaker, giving the helm or electrical panel a clearer way to manage start and house battery circuits.

This panel supports 12V and 24V DC systems with a maximum voltage of 32V DC. It is built around separate engine and house circuit control, emergency cross-connect between isolated battery banks, and protection for sensitive electronics from voltage sags and spikes that can happen during engine cranking.

It is a practical fit for boats that need organized battery control without turning battery switching into a complicated routine. With the addition of two Automatic Charging Relays, charging can be automated across three battery banks while keeping the switching layout easy to understand.

Key features

• Built for twin-engine battery systems with three battery banks when used with Automatic Charging Relays.
• Supports 12V and 24V DC installations, with a maximum voltage rating of 32V DC.
• Separates engine and house circuits so house loads are less likely to drain the starting battery.
• Allows emergency cross-connect between isolated battery banks when backup starting power is needed.
• Helps protect onboard electronics from voltage spikes and sags during engine cranking.
• Includes push-button thermal circuit breakers rated at 15A for 24-hour circuits.
• Uses a 100A C-Series flat rocker circuit breaker for main circuit protection.
• Ignition protected for installation aboard gasoline-powered boats.

Variants

This panel is offered in two configurations, with the position count and panel layout changing between versions.

Both variants serve the same core battery-management role for twin-engine boats, but their current ratings, dimensions, included switch type, and number of 15A push-button breakers differ by configuration.

• 8689, Positions 7. This version uses two m-Series Mini Dual Circuit Plus battery switches and has a square 7.25 in by 7.25 in panel footprint, which suits installations where panel space is tighter.
• 8693, Positions 11. This version uses two e-Series Dual Circuit Plus battery switches and has a wider 8.00 in by 10.50 in layout, giving more panel space for the additional 24-hour circuit breaker positions.

Electrical ratings

The 8689 variant is rated for 300A continuous current, 450A intermittent current for 5 minutes, 1000A cranking current for 10 seconds, and 650A cranking current for 1 minute.

The 8693 variant is rated for 350A continuous current, 525A intermittent current for 5 minutes, 1000A cranking current for 10 seconds, and 750A cranking current for 1 minute.

Installation and setup

The panel is intended for main battery distribution on boats where start and house banks need to stay isolated during normal operation but remain available for emergency parallel connection. It belongs in a dry, serviceable electrical area where the switches, breakers, labels, and wiring can be reached for operation and inspection.

Because this is a high-current battery management component, cable sizing, overcurrent protection, terminal torque, and routing should match the vessel electrical plan. Installation should also account for engine-room vibration, battery cable strain relief, and access for resetting the push-button breakers.

Use cases on board

This panel is a strong match for twin-engine cruising boats, fishing boats, and workboats that carry separate starting and house loads. It is especially useful where electronics, refrigeration, lighting, pumps, and other house circuits need to stay separated from the starting batteries during normal use.

For owners upgrading from scattered battery switches or unclear breaker layouts, this panel brings the main battery functions into one labeled control point, making everyday switching and emergency battery linking easier to manage.

Many products sold by Apollo Lighting include a manufacturer's warranty covering defects in materials or workmanship. Warranty terms vary by brand, product category, and model, so eligibility, coverage duration, exclusions, and available remedies are determined by the applicable manufacturer. We recommend reviewing the warranty information provided with your product before installation or use, especially for marine electronics, navigation equipment, lighting, electrical systems, pumps, safety equipment, and other specialized marine products.

If you need warranty service, the claim must follow the process established by the manufacturer, authorized service center, or designated warranty provider. You may be asked for proof of purchase, a serial number, product registration, photos, maintenance or installation records, or other documentation. Apollo Lighting does not determine or modify a manufacturer's warranty coverage or final claim decision, but we are happy to help provide purchase information and direct you to the appropriate manufacturer or warranty resource.

Keep your receipt, product documentation, serial number information, and original packaging when practical. Damage caused by normal wear, misuse, improper installation, insufficient maintenance, corrosion, impact, unauthorized modifications, electrical issues, or operation outside the manufacturer's specifications may not be covered. Warranty claims are separate from standard returns, so a product that has been installed, used, or exposed to marine conditions may no longer qualify for return while still remaining eligible for evaluation under the manufacturer's applicable warranty.
