All Redodo LiFePO4 Batteries

A LiFePO4 battery, short for Lithium Iron Phosphate, is a type of rechargeable lithium battery that uses iron phosphate as the cathode material. Unlike lead-acid or other lithium chemistries, LiFePO4 is valued for its long cycle life, stable voltage output, and enhanced safety. They are widely used in RVs, boats, solar energy storage, and off-grid applications because they deliver reliable power without maintenance.

LiFePO4 batteries have several clear advantages over lead-acid batteries. A quality LiFePO4 battery can last up to 15,000 cycles, significantly outlasting the 200-500 cycles of a traditional lead-acid battery. In terms of energy density, a lithium iron phosphate battery provides approximately 50.4Wh per pound compared to only 20Wh per pound for lead-acid, making them much lighter and more efficient. Additionally, LiFePO4 lithium batteries have a lower self-discharge rate than lead-acid batteries, which means they can be stored for extended periods without significant loss of energy. Moreover, lithium iron batteries are more environmentally friendly, as they don't contain hazardous materials like lead and acid, and they are less prone to sulfation.

Yes, you can use a LiFePO4 to replace a lead-acid battery in most applications, but it’s essential to make sure the charging system is compatible. Lithium iron phosphate battery require a specific charging profile and voltage, typically 14.6V for a 12V system, so it's important to switch to a charger specifically designed for LiFePO4 batteries.

Yes, LiFePO4 batteries are known for their safety due to their stable chemical composition. They are equipped with a Battery Management System (BMS), which protects the batteries from overcharging, over-discharging, overcurrent, short circuits, and overheating. The combination of stable chemical properties and safety systems makes them a safe choice for applications like solar setups, RVs, and marine boats.

Additionally, Redodo batteries are certified by UL-1973, CE, FCC, ROHS, UN38.3, which means they are tested and proven to meet international standards for safety, performance, and reliability.

Redodo LiFePO4 batteries operate in a wide range of temperatures, making them suitable for various climates.

• The discharge temperature range: -4°F to 140°F (-20°C to 60°C)
• The charging temperature range: 32°F to 122°F (0°C to 50°C)

Avoid charging below freezing temperatures, as this may cause battery damage.

We recommend the batteries with low-temperature protection. When the temperature drops below 0°C/32°F, the BMS automatically stops charging to ensure the internal safety of the battery, and resume charging when the temperature rises above 5°C/41°F.

Yes, our batteries can be connected in series to increase the system voltage, or in parallel to increase the capacity. For example, connecting two 12V LiFePO4 batteries in series creates a 24V system, and two 24V batteries for a 48V LiFePO4 battery pack. When connecting multiple batteries in parallel, you increase the amp-hour (Ah) capacity, allowing for longer run times. For optimal performance and safety, it’s essential to ensure that all batteries are identical batteries with the same type, capacity, BMS, and are purchased within one month.

For deep cycle LiFePO4 batteries, you can put up to 4 units in parallel or series for increased capacity or voltage. For starting batteries, parallel and series connections are not supported.

Yes, Redodo lithium phosphate batteries are well-suited for marine applications. They are much lighter than traditional lead-acid batteries, making them easier to install and less burdensome on a boat’s weight distribution.

Additionally, Redodo lithium marine batteries have an IP65/IP67 rating, offering protection against dust and water spray, making them ideal for use in boats, yachts, and kayaks. Further more, they provide more usable power and can handle the varying loads typical in marine applications better than lead-acid batteries.

LiFePO4 batteries typically last up to 10 years or about 4,000–15,000 cycles, far longer than lead-acid. On a single charge, the duration depends on the battery capacity and your power use. For example, a 100Ah battery may run a 50W refrigerator for 1 day, while larger 300Ah lithium battery can power it nearly 3.2 days.

Redodo batteries provide the four charging methods:

1. Lithium battery chargers: For 12V batteries, the charger voltage is typically 14.6V. For 24V batteries, the charger voltage is about 29.2V.

2. MPPT charger controller with solar panels

3. Alternator with DC-DC charger

4. Generator with AC-DC lithium battery charger

No, it is not advisable to charge a LiFePO4 battery with a lead-acid charger. As the charging modes of lead-acid batteries differ from those of LiFePO4 batteries, using a lead-acid charger may shorten the lifespan of lithium batteries and damage the battery's BMS. To ensure optimal performance and safety, it is best to use a charger specifically designed for LiFePO4 lithium batteries.

Proper storage of LiFePO4 lithium battery is important to maintain their longevity. Store the battery at about 50% charge level in a cool, dry place, away from extreme temperatures and humidity. If stored for extended periods, it is recommended to store the battery at a 50% charge level, and recharge it every 3 months to prevent it from discharging too low. Ideal storage temperatures for LiFePO4 are between 50°F to 95°F (10°C and 35°C). Following these guidelines ensures that your battery remains in optimal condition.
