Temperature Tolerant
Lithium batteries can handle a wide variety of conditions and are even 2.5x more efficient at low temperatures than lead-acid while being able to safely operate up to 149°F (65°C).
Lightweight
RELiON lithium batteries provide more power than lead-acid batteries and are typically half the weight. Boosting both performance and agility on the water.
Eco-Friendly & Safe
RELiON lithium batteries are the ultimate clean energy. No gassing, no fumes, and no pollution. Enjoy reliable power, while protecting the environment, using these non-hazardous batteries.
Constant Power
Full power available throughout discharge. Voltage does not drop like lead-acid.
Maintenance Free
Plug, play, and charge. No watering, no corrosion.

Read about the benefits and capabilities of the HP Series lithium batteries.
Understanding the basics of battery ratings and terminology is important when comparing and selecting the right type and number of batteries for your application to ensure you have enough energy to meet your energy goals.
The latest insights on lithium battery technology sent straight to you.
I had a terrible experience with 3x 225ah 8D batteries. The 50% to 80% SOC zone is not much power storage. I've added 2x 300HPs and while I only installed them 5 days ago so far so good. The power storage and more consistent voltage at just about any SOC has enabled installing an inverter and being able to use it, making stays on the hook a much easier experience.
