Our RB300-HP is a dual-purpose 12V, 300 Ah lithium battery. Our HP Series batteries are high performing dual purpose deep cycle batteries that can handle both starting and cycling. The RB300-HP has increased peak amps over our standard batteries. This increase in peak amps can be used to start motors, electric start generators and other high amp draw devices. After starting, the battery can double as a house battery providing power for peripherals, accessories and other onboard needs.

RELiON’s HP Series batteries are a perfect compromise between the unique demands of starting service and deep cycling, low amp draw service. The RB300-HP is a powerhouse for use in many marine applications including sailboats and catamarans.

The RB300-HP features installation flexibility and no maintenance over the life of the battery. It maintains consistent power and is equipped with an M8 terminal type and a built-in battery management system (BMS).
