Shop RELiON Lithium Batteries
For those who are considering switching from lead-acid batteries to Lithium, this article discusses the key reasons to consider RELiON. This discussion covers RELiON Lithium Battery safety, performance, charging requirements, cost, and common marine applications.
RELiON Lithium Iron Phosphate Batteries are Safe
Compared to other Lithium-Ion battery chemistries (Lithium Cobalt Oxide, Lithium Manganese Oxide), Lithium Iron Phosphate batteries are commonly considered the most stable, or safest. At West Marine, we view safety and reliability as the top priorities, which is why we recommend RELiON Lithium Iron Phosphate batteries for use on boats.
Key Advantages of RELiON Batteries
- More Usable Power: Lithium batteries provide consistent power throughout their discharge cycle, even under heavy loads, ensuring reliable performance for your electrical equipment and motors.
- Ultra-Fast Charging: Thanks to their flat voltage curve during charging, Lithium batteries charge rapidly. With the right charger, you can achieve a full charge in as little as 2.5 hours.
- Extended Cycle Life: RELiON batteries deliver up to charging 3,500 cycles, which is far greater than traditional batteries that provide significantly fewer cycles at shallower depths of discharge.
- Lightweight Design: Lithium batteries are substantially lighter than lead-acid counterparts. This reduced weight benefits various boat types, improving weight distribution and draft.
Is the Cost Justified?
Though the initial cost of Lithium batteries is much higher than traditional lead-acid batteries, their extended lifespan and performance make them more cost-effective in the long run. They can pay for themselves in just a few years, depending on your battery usage and the cost of your current batteries.
Other Features and Considerations
Built-In Battery Management System: RELiON batteries feature a Battery Management System (BMS) that protects against harmful conditions, ensuring the safety and longevity of your investment.
Battery Charger Compatibility: For efficient charging, use chargers designed for Lithium-ion batteries, like ProMariner ProNautic and ProSport HD chargers. Ensure your alternator and regulator are also Lithium-compatible for safe charging.
Battery Monitoring: Traditional voltage-based monitoring methods aren't suitable for Lithium batteries. State of Charge (SoC) monitors with shunts are essential for accurate tracking of amperage flow in and out of the battery.
Selecting the Right Size: RELiON batteries allow deeper discharges, reducing the need to restrict depth of discharge to 50%. This means you can use smaller Lithium batteries compared to traditional lead-acid batteries. They are an excellent choice for applications with high electrical loads.
RELiON Battery Applications
The majority of RELiON batteries are designed for deep cycle applications, such as powering "house" loads on a boat. Select models are offered for engine starting use.
Conclusion
RELiON batteries offer boaters a superior power solution. While they may not suit every application, they can significantly enhance your boating experience, particularly if you have high electrical load requirements.
