Marine Batteries

Redodo provides a range of marine batteries including marine starting batteries, deep cycle 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 pwoer, 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 marine trolling motors or other electronics like fish finders and GPS systems, you can choose from various deep cycle marine batteries 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 can provide 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. Their high energy density means they deliver more power per pound compared to traditional lead-acid batteries. These lithium marine batteries also boast a long cycle life, with some models providing up to 15,000 cycles at 60% depth of discharge (DOD). The built-in Battery Management System (BMS) protects the lithium ion marine battery from overcharging, over-discharging, overcurrent, overheating, and short circuits, ensuring safe and reliable performance. Additionally, with an IP65/IP67 waterproof rating, these batteries are well-suited for wet and marine environments.

Redodo marine lithium ion batteries are designed to last up to 10 years, depending on usage and maintenance. These batteries 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%, more than 6,000 discharges at 80%, and over 15,000 cycles at 60% depth of discharge. Their long lifespan makes these lithium boat batteries 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 batteries are designed to provide continuous power over extended periods, making them ideal for powering trolling motors and running electronics onboard. Deep cycle marine batteries can handle repeated deep discharges. Marine cranking batteries, on the other hand, are optimized to deliver high CCA needed to start an engine quickly. Redodo lithium marine batteries are available in both deep cycle and cranking configurations, allowing boaters to select the most appropriate battery type for their specific needs.

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

The weight of Redodo lithium ion 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. Despite their larger capacity, these lithium ion marine batteries are lighter than traditional lead-acid options, making them easier to handle and install.

To charge Redodo lithium ion marine batteries, use a dedicated LiFePO4 battery charger, and the recommended charging current is typically 0.2C. The recommended charging voltage for a 12V LiFePO4 marine battery 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 or alternators, as long as they are compatible with LiFePO4 batteries and have the correct voltage output.

Each Redodo lithium ion 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 lithium boat batteries come equipped with an advanced Battery Management System (BMS) that includes protections against overcharging, over-discharging, overcurrent, overheating, and short circuits. Some batteries are additionally equipped with low-temp cut-off protection or smart Bluetooth monitoring function. Some batteries with 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.
