RELiON® HP Series Batteries: High-Power, Dual-Purpose Marine and RV Batteries

RELiON® HP Series batteries are designed to deliver a burst of high current, making them ideal for starting boats, generator motors, or other high-amp devices. Beyond their starting capability, these batteries double as a reliable power source for marine and recreational vehicle (RV) applications. Built with LiFePO4 (Lithium Iron Phosphate) chemistry, these batteries are safe, stable, and generate minimal heat, ensuring they are suitable for high-demand environments. RELiON® HP batteries provide the perfect balance between starting power, deep cycling, and low amp draw service.

These batteries are rated up to 12V (nominal 12.8V) and are compatible with marine dual-purpose starting applications (gas, diesel, propane engines). Note that HP Series batteries should not be connected in series but can be used in parallel setups.Learn more about the HP Series. Watch a video on how to read a RELiON data sheet.
