Marine Lithium Battery Chargers

Yes, our on-board marine lithium battery chargers are IP68 waterproof rated, meaning they are completely protected against dust ingress and can withstand submersion in water. This makes them ideal for marine environments and ensures reliable performance, even in wet or damp conditions.

Not at all! Our chargers are low-maintenance. To ensure their longevity, simply inspect them periodically for any buildup of salt or debris and rinse gently with fresh water if necessary.

Our chargers are specifically engineered to withstand the harsh marine environment, including exposure to saltwater and salt ingress. They are built with corrosion-resistant materials to ensure long-lasting durability, even in extreme saltwater conditions.

At ABYSS®, we are dedicated to enhancing your marine adventures with our state-of-the-art 12V lithium marine batteries, designed to seamlessly integrate with your existing AGM battery charging system. With a precise voltage requirement of 14.4V-14.6V, transitioning to lithium power has never been easier or more convenient. We also have our own selection of 12V On-Board Marine Chargers to meet your needs.

Charging Solutions for 24V and 36V Trolling Motor Batteries:


Similarly, our 36V lithium trolling motor batteries benefit from specialized charging options. The 36V 10A charger is ideal for our 36V 60Ah and 72Ah batteries, while the more robust 36V 20A charger is crafted for the demanding energy needs of our 36V 105Ah battery.

Yes, our chargers are optimized for use with Abyss Battery lithium marine batteries, but they are also compatible with most other lithium iron phosphate (LiFePO4) batteries, offering safe and efficient charging. Our Multi-Bank Chargers are also compatible with Lead-Acid and AGM batteries.

For those navigating with our robust 24V battery systems, we offer tailored charging solutions to match your energy needs. Choose from our efficient 24V 10A charger, perfectly suited for our 24V 60Ah and 24V 75Ah batteries, or upgrade to the more powerful 24V 20A charger, designed specifically for our 24V 100Ah battery. These options ensure your battery is charged quickly and ready for your next adventure.

Our 36V lithium trolling motor batteries benefit from specialized charging options. The 36V 10A charger is ideal for our 36V 60Ah and 72Ah batteries, while the more robust 36V 20A charger is crafted for the demanding energy needs of our 36V 105Ah battery.

The Abyss® 36V DC-DC Charger is designed to give your 36V trolling motor battery a boost while you're on the go by harnessing power from your engine’s alternator. As your boat moves, the alternator generates excess power, which the charger redistributes from your cranking battery to your 36V battery, providing up to 10 amps of charging voltage as needed.

This smart on-demand technology only supplies the charging current necessary to replace used energy, helping extend your trolling motor battery life. Additionally, it ensures that your cranking battery’s voltage won’t fall below 13.3V, so you can safely rely on your boat’s systems and keep your trolling motor charged and ready.

It is not recommended to use a 36V DC alternator charger with three 12V lithium batteries in series. While the voltage may match, charging batteries connected in series with a 36V charger can lead to imbalanced charging, potentially causing:

• Uneven Charging: The charger cannot individually balance each 12V battery, which can result in one or more batteries being overcharged or undercharged, reducing their lifespan.
• System Instability: Imbalanced batteries can cause performance issues and even damage the battery pack or the alternator charger.
• Safety Concerns: Uneven charging increases the risk of overheating, which may compromise the safety of the battery system.
