The Safest, Most Reliable Marine Cranking Battery

Unmatched 800 Cold Cranking Amps (CCA): Our battery is suitable for fuel-injected outboard motors up to 135 HP. However, please consult your engine's manual to confirm it meets the required CCA ratings.

Top Automotive-Grade Prismatic LiFePO4 Cells: Built with the industry's highest-quality prismatic cells that excel in shock and vibration resistance compared to soft-pack cells, providing over 5,000 cranking cycles—three times the lifespan of traditional SLA batteries.

Proprietary Structural Design: Our self-developed, patented design features high-strength metal reinforcements to control thermal expansion, extending battery life and durability—ensuring reliable performance on the water, every time.

Low-Temp Cutoff Protection: Charging automatically pauses below 32°F and resumes above 41°F. Discharge also stops at -4°F to keep your battery safe in freezing conditions.

Upgraded BMS for Enhanced Safety: Our advanced Battery Management System protects against overcharge, over-discharge, over-current, short circuits, and low & high temperatures.

IP67 Waterproof, Dustproof, & Salt Spray-Proof: Built to withstand marine and humid environments.

40-Minute Super-Fast Charging: Fully charged in 40 minutes with a 30A current and supports up to 80A from an outboard motor’s alternator for rapid replenishment.

Meets ABYC Standards: All Redodo marine batteries meet ABYC standards and undergo rigorous testing and certification, including UL1973, FCC, CE, RoHS, and UN38.3.

Friendly Reminder: Ideal as a marine cranking battery and also compatible with lawnmowers requiring Group U1 size. Not recommended for use in cars or tractors.

Why are we the safest and most reliable marine cranking batteries?

Top Automotive-Grade Battery Cells, Excellent Impact Resistance, Perfect for Marine Use

Redodo uses prismatic cells, which are more resistant to external shocks and vibrations and maintain a low temperature even at high power output. In contrast, other soft-pack starting battery cells have poor heat dissipation, requiring additional cooling measures to ensure safety.

Industry-leading structural design

Restraining the thermal expansion of battery cells and improving battery life

Redodo starter batteries use high-strength metal fixation, which can efficiently and safely control the thermal expansion of battery cells, allowing the battery cells to always work stably within a safe range, extending the battery life.

FAQ

Q: Can the battery to be used to start alternator in the car?

A:

No. Please DO NOT use it as a starter battery for any type of vehicle, suchas cars, motorbikes, tractors, etc.

Q: How do I know whether the battery can be applied to start my fuel outboard motor?

A:

Please ensure your fuel outboard motor can meet below conditions when choosing the battery:

1. Please ensure the CCA value that your fuel outboard motor required is < the CCA value(650A) of the battery.


2. Please ensure the output current of the alternator < the max. charging current(80A) from alternator that the battery supports if there is an alternator in the fuel outboard motor.

Q: What's the waterproof rating of the battery?

A:

The battery can support IP67 protection. To avoid potential issues, it is recommended to install the battery in a waterproof battery container and/or position it at a higher level. This will prevent the battery from being partially or wholly submerged in the water accumulated at the bottom of the boat.
