Perfect Power Solution for Narrowboats
The LR51.2-100 (48V 100Ah) lithium battery offers a significant upgrade over traditional lead-acid systems. Because it uses Lithium Iron Phosphate (LiFePO4) chemistry, it ensures inherent safety in confined boat spaces. Furthermore, the UL94V-0 flame-retardant housing and the built-in BMS provide automatic protection against over-charging and extreme temperatures.
Why the LR51.2-100 is Ideal for Your Vessel
- Peak Efficiency: It achieves 99% charge efficiency, meaning almost all power from solar panels or shore lines is stored.
- Exceptional Longevity: The battery delivers thousands of cycles, which significantly reduces replacement costs over time.
- Intra-System Balancing: This feature ensures every cell works in harmony to maximise the overall performance of the bank.
- Victron Integration: It connects seamlessly with Victron ecosystems, allowing the crew to view the State of Charge (SOC) without an external shunt.
Versatile Installation and Storage
The LR51.2-100 simplifies the transition to electric power through its adaptable design. For instance, you can install the unit in a standard 19-inch cabinet or mount it directly to a bulkhead to save valuable floor space. Because the system remains compatible with most standard VRLA chargers, making the switch to lithium is both affordable and straightforward.
Furthermore, this battery is perfectly winter-ready. With a low self-discharge rate of up to two years, users can store their boats for the season without worrying about battery degradation. Ultimately, the Törkmar-approved Leoch battery provides a safe, long-lasting, and high-performance energy heart for any modern narrowboat.
