Lithium Marine Batteries

Redodo provides a range of marine batteries including marine deep cycle batteries, starting batteries, dual-purpose batteries, and outboard motor batteries. Choosing the right lithium marine battery depends on several factors, such as the engine type, and the energy needs of your equipments.

For starting power, it's important to identify your engine type.

• For electric engines, you should opt for the Electric Outboard Motor Battery.
• For fuel engines, a Marine Cranking Battery is an ideal starting option. Ensure that your engine’s CCA and horsepower value are meet the battery’s requirements.

For trolling motors or other electronics like fish finders and GPS systems, you can choose from various options, such as our lithium trolling motor battery, fish finder battery, etc.

We also offer Dual-purpose Marine Batteries suitable for both starting and deep cycle applications, which feature high CCA for starting engine and prolonged power supply for boat electronics.

Redodo marine boat batteries offer several advanced features, making them ideal for marine applications.

1. High energy density: It means they deliver more power per pound compared to traditional lead-acid batteries.

2. Long cycle life: The deep cycle models providing 4,000 cycles at 100% DOD (depth of discharge), and up to 15,000 cycles at 60% DOD.

3. Advanced BMS protections: Prevent the lithium marine battery from overcharging, over-discharging, overcurrent, overheating, and short circuits, ensuring safe and reliable performance.

4. IP65/IP67 waterproof rating: Makes them well-suited for wet and marine environments.

Redodo lithium batteries for boat are designed to last up to 10 years, depending on usage and maintenance. They are built to handle lots of charging and discharging, which makes them dependable for the long run.

For cranking purpose, the marine cranking batteries can provide 5000+ cranking times. For deep-cycle purpose, they can go through 4,000+ discharges at 100% DOD. The long lifespan makes them a cost-effective choice for boat owners seeking long-term reliability.

Yes, you can connect multiple these batteries in parallel to increase the overall capacity without altering the system voltage. For deep cycle use, you can connect up to 4 batteries in parallel. For marine cranking battery, it does not support multiple batteries in parallel.

When connecting the LiFePO4 batteries in parallel, ensure that all units are of the same type, BMS, and capacity, and are purchased around the same time (within one month).

Deep cycle marine batteries are designed to provide continuous power over extended periods, making them ideal for powering trolling motors and running electronics onboard. They can handle repeated deep discharges.

On the other hand, marine cranking batteries are optimized to deliver high CCA needed to start an engine quickly.

Yes, Redodo lithium batteries for deep cycle are designed with an IP65 waterproof rating, while the cranking batteries and dual-purpose batteries are an IP67 rating. They offer protections against dust and water spray, making them suitable for use in marine environments. However, for long-term protection, it is recommended to install your battery in the boat cabin or put it in a marine battery box.

The weight of Redodo marine battery varies by model. For example, the typical 12V 100Ah trolling motor battery weighs approximately 22.05 lbs, while larger models like the 12V 200Ah battery weigh around 43.98 lbs. These lithium batteries are much lighter than traditional lead-acid options, making them easier to handle and install.

Use a dedicated LiFePO4 battery charger to charge these batteries, and the recommended charging current is typically 0.2C.

For a 12V LiFePO4 marine battery, the recommended charging voltage is typically between 14.2V and 14.6V. For 24V LiFePO4 batteries, the recommended charging voltage is between 28.4V and 29.2V. For 36V LiFePO4 batteries, the recommended charging voltage is between 42V and 43.8V.

Additionally, these marine lithium batteries can be charged by solar panels, generators, or alternators, as long as they are compatible with LiFePO4 batteries and have the correct voltage output.

Each Redodo lithium marine battery is maintenance-free. However, due to marine boat batteries are often exposed to water and other harsh conditions, it’s necessary to check terminals for corrosion regularly. When not in use, store your batteries in a cool, dry place, keep them at a 50% charge level, and recharge every 3 months to prevent them from discharging too low.

Redodo batteries come equipped with a Battery Management System (BMS) that includes protections against overcharging, over-discharging, overcurrent, overheating, and short circuits.

Some upgraded models are additionally equipped with low-temp cut-off protection and smart Bluetooth monitoring function. The upgraded BMS adds additional pre-charge functions, automatic recovery after protection, enhanced moisture-proof, and salt-spray anti-levels. These features ensure safe operation under various conditions and help prolong the overall lifespan of the battery.
