About this item

A rackable 48V lithium iron phosphate battery, the safe one, ideal for use in powering narrowboats and widebeams alike. A strong feature is the robust built-in BMS which has been configured to communicate directly with Victron equipment

Perfect power solution for boat like narrowboats

The LR51.2-100 (48V 100Ah) lithium battery is the perfect power solution for narrowboats, offering a significant upgrade over traditional lead-acid batteries. Its Lithium Iron Phosphate (LiFePO4) chemistry is inherently safe, providing peace of mind in the confined spaces of a boat due to a flame retardant system to UL94V-0. The built-in Battery Management System (BMS) offers automatic protection against over-charge, over-discharge, and over-temperature conditions, extending the battery’s lifespan and ensuring safe operation. The BMS is Victron compatible and means that there is no need for a shunt to view the State of Charge (SOC)

Why the LR51.2-100 is Ideal for Narrowboats

For narrowboat owners, the LR51.2-100 is a powerhouse of efficiency. Its 99% charge efficiency means that nearly all the power you put in, whether from solar panels, a generator, or shore power, is stored and available for use. This dramatically reduces energy waste and maximizes the performance of your charging sources, a critical factor when living off-grid. In contrast, lead-acid batteries can lose up to 15-20% of their energy during charging.

The battery’s high cycle times and long service life mean you can rely on it for thousands of cycles, far outlasting conventional batteries and reducing the need for costly replacements. The intra-system balancing ensures each cell works in harmony, maximizing the battery’s overall performance.

Another key advantage is its compatibility with Victron products. This allows for a seamless and highly efficient power system, from monitoring your battery’s state of charge to managing solar input and inverter output—all within one integrated ecosystem. The battery is also incredibly versatile in installation, designed to fit into a 19-inch standard cabinet or be wall-mounted, making it easy to integrate into the limited space on a narrowboat. Finally, its ability to use most standard VRLA chargers offers a simple and affordable upgrade path. With a low self-discharge rate of up to two years, you can store your narrowboat for the winter without concern.
