Upgraded Solutions for Better Performance

Keep your boating days worry-free with Power Sonic’s range of high-quality Hyper Sport Marine line! Marine lithium batteries are transforming how boats are powered, with benefits like higher efficiency, maintenance-free operation, and a longer-lasting alternative to traditional sealed lead-acid (SLA) batteries.

What Are Marine Lithium Batteries?

Power Sonic’s marine lithium batteries are designed to power marine applications like boats, yachts, and other watercrafts, using lithium iron phosphate (LiFePO4) chemistry to store energy.

Lithium batteries have been making waves in various industries due to their superior energy density, longer lifespan, and environmental benefits compared to SLA batteries.

Why Choose Power Sonic’s Marine Lithium Batteries

1. Enhanced Performance and Efficiency

One of the most significant benefits of marine lithium batteries is their high energy density. Power Sonic’s marine lithium batteries deliver twice the power of SLA batteries, even high discharge rate, while maintaining high energy capacity. This means you get longer cruising distances and less weight onboard — critical for boat performance!

Additionally, marine lithium offers consistent power output throughout their discharge cycle. Unlike SLAs, which experience a drop in voltage as they discharge, lithium batteries maintain a steady power supply, making them more reliable for powering both electric propulsion systems and onboard electronics.

2. Longer Lifespan

When compared to SLAs, Power Sonic’s marine lithium batteries have an impressively long lifespan. While SLAs may last around 2-4 years with proper maintenance, our Hyper Sport Marine Lithium range of batteries can easily last 10 years or more (depending on usage), further reducing long-term costs of boat ownership. This longevity allows you to save both time and money, as you don’t need to replace batteries as frequently.

3. Fast Charging and Deep Cycling

Another attractive feature of marine lithium batteries is their rapid charging capabilities. Batteries like Power Sonic’s PSL-BT-24400-G24 charge significantly faster than lead-acid options, which means less downtime between excursions. In addition, our lithium batteries can handle deep cycling without the degradation seen in lead-acid counterparts, allowing them to be discharged and recharged thousands of times without losing capacity.

4. Weight Savings

Weight is always a consideration for boat owners, whether it’s for performance, fuel efficiency, or space management. Marine lithium batteries like the PSL-BT-36400-G31 (depicted below) could save you up to 200lbs or 40% of weight compared to a traditional SLA battery.

This reduction in weight improves overall boat performance, enhances fuel efficiency, and creates more room for other onboard equipment or personal storage.

5. Environmentally Friendly

Sustainability is a driving force in the boating industry. As environmental regulations tighten and consumers seek more eco-friendly options, lithium batteries offer a greener alternative to traditional SLA batteries. Not only are lithium batteries more efficient but they are also recyclable and do not contain toxic materials like lead or acid. Power Sonic’s LiFePO4 chemistry is also ethically sourced, further contributing to lithium’s environmentally friendly appeal.

6. Bluetooth Capabilities through Power Sonic Lithium App

Our lithium batteries feature advanced Bluetooth technology, giving you complete control and peace of mind. With real-time monitoring from your smartphone, you can check your state of charge, battery health, and power status—no more guessing or relying on a trickle charger. Easily verify if your battery is off and ensure it’s ready to power your entire marine adventure. The benefits of this smart technology mean you can enjoy worry-free outings, knowing your marine lithium battery will deliver reliable, consistent performance throughout your trip. Stay focused on the water, not your battery.

The Future of Marine Lithium Batteries

The future of marine lithium batteries is promising. As battery technology continues to improve, we can expect even better performance, higher energy densities, and faster charging capabilities.

Moreover, as the global push for cleaner energy and sustainable practices grows, the marine industry will likely see an increasing shift toward electric and hybrid vessels powered by sustainable lithium batteries. In the coming years, we may see a wider adoption of lithium batteries in commercial and leisure boating, making it easier for everyone to enjoy the water while minimizing their environmental footprint.

Planning approval for B2B green hydrogen facility

Planning approval for B2B green hydrogen facility

Planning approval has been granted for Energys’ green hydrogen production facility in Hastings, Victoria, after 18 months of dedicated engagement with the Victorian planning system.

This project represents a significant step forward in Australia’s energy transition. The commercially focused green hydrogen B2B industrial supply initiative is aimed at displacing grey hydrogen currently produced from natural gas.

At the core of the facility will be a 1 MW proton exchange membrane (PEM) electrolyser, powered by grid electricity during periods of surplus renewable generation and low wholesale energy prices.

Under a strategic agreement, Coregas — an Australian producer of liquid hydrogen — will operate the site and manage all downstream logistics including compression, liquefaction, cylinder and trailer filling, and distribution to end users. Hydrogen produced at the Hastings facility will be marketed and sold under commercial terms through Coregas to a growing base of industrial and mobility customers.

“This project positions Victoria at the forefront of green hydrogen innovation,” said Roger Knight, CEO of Energys. “By displacing emissions-intensive grey hydrogen with a zero-carbon alternative, we are making a tangible contribution to decarbonising key sectors such as industrial gas, transport and stationary energy.”

Green hydrogen supplied from this site will reduce emissions in the stationary power along with road and marine transport markets through the displacement of diesel.

Energys’ core activity is the manufacture of hydrogen fuel cell power systems and this project will supply green hydrogen to the Victorian market including the company’s customer base.

The project’s operating model leverages grid flexibility, utilising electricity during periods of excess supply, which aligns with broader energy market goals of enhancing system stability and integrating renewable energy.

This development reinforces the company’s commitment to advancing practical, scalable clean energy solutions that support Australia’s net-zero ambitions and foster a low-emissions future.

Energys received support from the Victorian Government through The Renewable Hydrogen Commercialisation Pathways Fund (CPF).
