On Board Chargers

Marine Onboard Battery Chargers
Keep your batteries fully charged and ready for every trip with a marine onboard battery charger. Whether you're running traditional lead-acid batteries, AGM batteries, or upgrading to lithium, the right onboard charger helps maximize battery performance, extend battery life, and eliminate the hassle of charging each battery individually.

At Deep V Rigging Company, we offer premium onboard chargers designed for today's fishing boats and marine electrical systems, with options for starting batteries, trolling motor batteries, dedicated electronics batteries, and complete multi-bank charging systems.

Why Install an Onboard Battery Charger?
An onboard charger permanently mounts inside your boat, allowing you to recharge your batteries by simply plugging in a single extension cord after each trip.

Benefits include:

• Convenient one-plug charging
• Automatically charges each battery independently
• Extends battery life
• Reduces maintenance
• Keeps batteries fully charged and ready to go
• Ideal for multi-battery boats

Whether you have a single starting battery or a three-battery 36V trolling motor system, an onboard charger simplifies battery maintenance.

Smart Charging for Every Battery Type
Modern marine chargers use advanced charging algorithms that safely charge different battery chemistries while maximizing performance and longevity.

Lithium Batteries
Lithium batteries require a charging profile specifically designed for lithium chemistry. Compatible chargers deliver the proper charging voltage and automatically stop charging when the battery reaches full capacity.

• Benefits include:
• Faster charging
• Full battery capacity
• Maximum battery lifespan
• Safe charging with compatible lithium Battery Management Systems (BMS)

We recommend using a lithium-compatible onboard charger with Amped Outdoors Lithium Batteries and other lithium marine batteries.

AGM Batteries
AGM (Absorbed Glass Mat) batteries require a different charging profile than flooded batteries. Smart chargers carefully regulate charging voltage to maximize battery life while preventing overcharging.

Benefits include:

Longer AGM battery life

Full charging capacity

Reduced sulfation

Maintenance-free operation

Flooded Lead-Acid Batteries
Traditional flooded batteries benefit from multi-stage charging that helps fully recharge the battery while reducing the risk of overcharging and excessive water loss.

Proper charging helps:

• Extend battery life
• Improve starting performance
• Reduce sulfation
• Maintain battery capacity over time

Multi-Bank Charging Systems
Marine onboard chargers are available in multiple configurations to fit your boat's electrical system, including:

• Single-bank chargers
• Two-bank chargers
• Three-bank chargers
• Four-bank chargers

Each charging bank operates independently, allowing batteries of different sizes and states of charge to be charged simultaneously.

Perfect for Every Marine Battery System
Onboard chargers are ideal for charging:

• Starting batteries
• Trolling motor batteries
• Dedicated electronics batteries
• Dual purpose batteries
• 12V, 24V, and 36V trolling motor systems
• Lithium battery systems
• AGM battery systems
• Flooded lead-acid batteries

Whether you're running one battery or a complete tournament-ready power system, there's an onboard charger designed for your application.
