Obsoleting Lead-Acid Batteries
Lead-acid cranking batteries are outdated technology for marine applications. Their weight and limited lifespan make them a less-than-ideal choice for boat owners. Lithium-ion batteries offer a significant upgrade in performance and convenience.
The shift to lightweight lithium batteries provides numerous advantages, including increased power, longer lifespan, and reduced weight for easier handling and transportation.
This review focuses on the performance and capabilities of a specific lithium cranking battery, analyzing its suitability for various boating needs.
Introducing the Redodo 20Ah Lithium Iron Phosphate Battery
The Redodo 20Ah Lithium Iron Phosphate battery is a dedicated cranking battery, not a deep-cycle battery. It's specifically designed for starting outboard motors, unlike batteries used for trolling motors or other onboard electronics.
With a rating suitable for approximately 135 horsepower outboards, this battery boasts impressive cranking amps. It offers 900 amps at normal temperatures and 810 MCA (Marine Cranking Amps) in cold conditions.
Despite its compact size and weight, its high cranking amperage ensures reliable starting performance even under cold conditions.
Size, Weight, and Performance Considerations
The small size and lightweight nature (9.12 lbs) of the 20Ah battery might seem concerning, but the high cranking amps compensate for the lower amp-hour rating. This is because starting a motor only requires a short burst of power.
The battery's small size and weight are a major advantage, offering significant improvements in portability compared to traditional lead-acid batteries. This makes handling and transport much easier.
Despite its small size, this battery delivers plenty of power to start even larger motors, making it a convenient and practical solution.
Advanced Features and Protection
The battery includes a Battery Management System (BMS) designed specifically for cranking applications to handle high current demands effectively and safely.
Features like low-temperature charge protection ensure the battery operates reliably across a wider temperature range, preventing damage from overcharging in cold conditions.
The BMS also safeguards against over-discharge and overcharge, extending battery lifespan and overall reliability.
Cold Weather Performance Test
A cold-weather test demonstrated the battery's ability to start an outboard motor in sub-freezing temperatures after being exposed to snow overnight. This confirms its reliability in demanding conditions.
The quick and effortless start-up of the outboard motor showcases the impressive cold-cranking capabilities of this battery.
This test proves its capability to handle cold-weather challenges effectively, unlike many traditional batteries which struggle under cold conditions.
Charging Considerations and Compatibility
The battery is compatible with various charging systems, including alternators and multi-bank chargers. Its fast charging capabilities allow for quick replenishment after use.
It's crucial to verify compatibility with your specific outboard motor and charging system before installation. Using an incompatible charger can damage the battery.
Consult the manufacturer's guidelines for proper charging procedures to ensure optimal performance and extend the battery's lifespan.
Conclusion: Is the Redodo Lithium Cranking Battery Worth It?
The Redodo 20Ah Lithium Iron Phosphate battery offers a compelling alternative to lead-acid cranking batteries for outboard motors. Its lightweight design, high cranking amps, and robust cold-weather performance make it a practical choice.
The battery's long lifespan and ease of use offset the initial cost, making it a worthwhile investment in the long run. The improved portability and performance far outweigh any minor drawbacks.
For boaters seeking a reliable, lightweight, and durable cranking battery, the Redodo 20Ah battery is a strong contender. It provides considerable advantages in terms of performance, weight, and overall convenience.
