36V Lithium Batteries

The Redodo 36V lithium battery offers several advantages over traditional lead-acid batteries and other types of lithium batteries. Firstly, it utilizes Lithium Iron Phosphate (LiFePO4) as the cathode material, known for superior thermal stability to enhance safety. Redodo 36V lithium-ion battery, for example, the 36V 50Ah Lithium Trolling Motor Battery, delivers a stable 50A discharge current, with the capability to handle up to 60A for 30 minutes and a peak surge of 250A, making it suitable for high-demand applications like trolling motors with 100-120 lbs of thrust. Additionally, the built-in Battery Management System (BMS) provides comprehensive protection against overcharging, over-discharging, over-current, short circuits, high & low temperatures, ensuring reliable and safe operation. The upgraded BMS is equipped with pre-charge functions, automatic recovery after overload protection in just 30 seconds, and improved resistance to moisture and salt spray.

The Redodo 36V LiFePO4 battery is designed for exceptional longevity. It offers over 4,000+ cycles at 100% depth of discharge (DOD). By reducing the DoD to 60%, the cycle life can extend up to 15,000 cycles, significantly surpassing the lifespan of traditional 36 volt lithium-ion battery and lead-acid types. This extended cycle life translates to approximately 10 years of service under typical usage conditions, providing a reliable and long-term power solution for applications requiring a 36 volt lithium battery.

Yes, the Redodo 36V lithium battery supports parallel connections to increase capacity. However, it is not recommended to connect these 36V batteries in series to increase voltage, as it can lead to BMS damage and potential safety issues. You can connect up to four of these 36 volt 50Ah lithium ion batteries in parallel, creating a 36V (38.4V nominal) system with a total capacity of 200Ah, equating to 7.68 kWh of energy storage. This configuration is ideal for applications requiring extended runtime or higher energy reserves, such as trolling motors, home energy storage systems, and solar installations. Always ensure that 36V lithium batteries connected in parallel are of the same type, BMS, capacity, and brand, to maintain system integrity and safety.

The charging time for a Redodo 36V battery depends on the charger’s output current and the battery’s SOC. For instance, using a charger with a 36V (43.8V) 20A output, a fully discharged 36V battery lithium (50Ah) would take approximately 2.5 hours to reach full charge (50Ah ÷ 20A = 2.5 hours). It's important to use a LiFePO4 batteries charger for the 36V LiFePO4 battery and follow the manufacturer’s charging guidelines to ensure safety and optimize battery lifespan.

While both are lithium-based, the Redodo 36V LiFePO4 battery and the other 36V lithium-ion battery differ in chemistry, performance, and safety. Traditional 36 volt li ion batteries, such as those using lithium cobalt oxide (LiCoO₂) or lithium manganese oxide (LiMn₂O₄) as cathode materials, offering higher energy density than LiFePO4 battery. However, they are less stable and more prone to thermal issues under some conditions. In contrast, our 36V lithium battery has slightly lower energy density, but it provides significantly enhanced thermal stability, reducing the risk of overheating and fire. Due to the upgraded BMS, the 36V LiFePO4 battery also maintain better safety performance in extreme temperatures. Additionally, our LiFePO4 batteries offer an extended cycle life of 4,000-15,000 cycles, compared to around 500-1,000 cycles for many standard lithium-ion batteries.

Redodo 36V lithium batteries are equipped with a comprehensive BMS that provides multiple layers of protection. The BMS safeguards against overcharging, over-discharging, over-current, short circuits, and high temperatures, ensuring safe and reliable operation. Additionally, the 50A 36 volt li-ion battery features low-temperature cutoff protection, automatically stopping charging below 32℉ and resuming above 41℉, while discharge stops below -4℉, making it suitable for cold-weather use. The upgraded BMS also includes pre-charge functions, automatic recovery after overload protection in 30 seconds, and added protection against moisture and salt spray, enhancing safety and user convenience.

The Redodo 36V lithium marine battery is designed to operate within specific temperature ranges to ensure optimal performance and safety. They can discharge with a wide temperature range of -20℃ to 60℃ (-4℉ to 140℉). For charging, the temperature range is 0℃ to 50℃ (32℉ to 122℉). Charging below 0℃(32℉) will damage the battery. The 36V lithium-ion battery 50Ah model features low-temperature protection, where charging will automatically stop if the battery temperature drops below 0℃ (32℉) and will resume once it reaches above 5℃ (41℉).  These functions help maintain the safety, performance, and lifespan of 36V lithium battery.

The Redodo 36 volt lithium battery requires minimal maintenance. When not using, store the batteries in a cool and dry place, ideally between 10℃ to 35℃ (50℉ to 95℉), and avoid prolonged exposure to extreme temperatures to ensure longevity. For long-term storage, keep the 36V lithium batteries at around 50% charge and check them every three months to extend battery life. Use a LiFePO4-compatible charger, as using an incompatible charger may damage the 36V lithium battery.

Redodo 36V lithium batteries are particularly popular for powering trolling motors as marine batteries due to their ability to deliver consistent power and withstand deep cycles. Other common uses include solar energy storage systems, camping setups, and as backup power sources for off-grid applications. These lithium 36V batteries provide high energy density, lightweight design, and reliable performance, making them ideal for these deep-cycle uses. However, the 36 volt li-ion battery should not be used for engine starting or in applications requiring high power output, such as a marine starting battery, golf cart battery, or heavy industrial machinery, as these conditions could exceed the battery’s design limitations.

Redodo 36V LiFePO4 batteries are designed with an IP65 rating, providing reliable protection against dust and water spray. This makes them well-suited for marine environments and outdoor applications. However, to ensure the 36 volt lithium-ion battery's durability and performance in wet conditions, it's recommended to place the battery in a compartment or use a protective waterproof battery box, especially if it might be exposed to water. This additional protection helps maintain the longevity and safety of the 36V lithium-ion battery.
