WattCycle 24V 314Ah Ultra LiFePO4 Battery with Bluetooth | ECE R10 Certified

Yes. LiFePO4 batteries are among the most stable lithium battery technologies available on the market. WattCycle LiFePO4 batteries use high-quality Grade A LiFePO4 cells and are equipped with an integrated Battery Management System (BMS). This system provides protection against overload, overvoltage, extreme temperatures (including deep discharge protection), and more.

All WattCycle batteries undergo strict testing before delivery and are certified to standards such as CE, RoHS, UN38.3, and are classified as Class 9 dangerous goods. Buy with confidence.

The battery measures 480 × 362 × 242 mm (L × W × H) and weighs 69.85 kg.

No, this battery cannot be used to start a vehicle engine. However, it can be used as a house or auxiliary power supply battery for automotive applications.

A 24V 314Ah Ultra LiFePO4 battery has a total energy capacity of 8.038 kWh, calculated by multiplying the voltage (25.6 V) by the ampere-hours (314 Ah).

Yes. Our 24V 314Ah Ultra lithium battery is certified under ECE R10 approval (E5710R06/031949). The corresponding marking is printed on the battery housing. The certificate is not included in the package but can be downloaded and printed from the product page.

All WattCycle batteries use LiFePO4 technology with a service life of 5,000 to 15,000 full charge cycles, which typically corresponds to up to 10 years of use, depending on operating conditions.

The runtime depends on several factors, including battery capacity, connected load, and battery condition. A new battery performs better than a used one, as capacity gradually decreases over time with cycling.However, runtime can be estimated using a simple formula:

Battery runtime (hours) = Battery capacity (Wh) / Total device power consumption (W)

For example:8,038.4 Wh / 500 W = 16.07 hours

Yes. The WattCycle app is password-protected. Please make sure to download the latest version of the app, as older versions may not support or protect WattCycle Bluetooth batteries properly.

When opening the WattCycle app, you need to select the login mode and pair (connect) your Bluetooth battery.Through the app, you can monitor key battery data such as state of charge (SOC), voltage, current, temperature, and individual cell information.

The maximum charging current of our 24V 314Ah Ultra LiFePO4 battery is 300 A. However, we generally recommend charging at a rate of 0.2C, which equals 62.8 A, to ensure optimal performance and longer battery life.

The charging time depends on the configuration of your PV system, including the size of your solar panels and the capacity of your solar charge controller.For example, if the 24V 314Ah Ultra LiFePO4 battery covers your daily energy consumption and you have around 4.5 hours of effective sunlight per day, you would need to generate approximately 8,038.4 Wh of energy.To achieve this, you would require at least 1,786.31 W of solar panels, so a 2,000 W system is recommended. This could consist of four 500 W panels or five 400 W panels.For a 2,000 W PV system, the required charging current is approximately 167 A. However, most MPPT solar charge controllers on the market are typically rated at around 100 A, so it is recommended to use two 100 A MPPT charge controllers.

Two 12V 314Ah Mini batteries connected in series provide the same capacity as a single 24V 314Ah battery. The choice between these two options depends on your specific requirements, as both configurations have their own advantages and disadvantages:

• Two 12V 314Ah Mini batteries in series: If one battery fails, the system may still continue operating with partial functionality, which can help prevent sudden power loss (for example during travel applications).
  
• One 24V 314Ah Ultra battery: This configuration offers better cell consistency and more stable operation. It also requires less wiring and has a more compact design.

All WattCycle 24V LiFePO4 batteries support different configurations, including series, parallel, and series-parallel connections. You can connect up to 4 batteries in parallel and 2 in series, meaning a total of 8 units of the 24V 314Ah Ultra LiFePO4 battery can be combined, achieving a total energy storage capacity of approximately 64.31 kWh.

It is essential to always use the same battery model with the same voltage, and ensure that the batteries are not older than 6 months when used together in a system.

With up to 7,680 W of continuous power output and 8,038.4 Wh of energy, the WattCycle 24V 314Ah Ultra LiFePO4 battery is ideal as a deep-cycle auxiliary power supply for high continuous discharge applications (200 A – 310 A).

It is well suited for solar energy systems, home energy storage, camping, medium and large RVs/caravans, yachts, sailing boats, and backup power supply systems, among other uses.

The WattCycle 314Ah Ultra LiFePO4 battery uses a metal frame structure that is more robust than traditional methods of fixing battery cells. It effectively resists external vibration and impact, limits cell expansion, and ensures that pressure is evenly distributed across each cell.

This design helps prevent the terminals (anode and cathode connections) from being pulled or worn due to cell movement, thereby improving stability and extending the service life of the smart LiFePO4 battery.

Size differences:The 24V 314Ah Ultra LiFePO4 battery measures 480 × 362 × 242 mm, while the 24V 100Ah battery measures 482 × 170 × 241 mm.

Weight differences:The 24V 314Ah Ultra battery weighs 69.85 kg, compared to 21.70 kg for the 24V 100Ah battery.

BMS differences: The Battery Management System (BMS) of the 24V 314Ah Ultra battery is rated for 300 A, while the 24V 100Ah battery uses a 100 A BMS. This means the 24V 314Ah Ultra battery supports a continuous charge and discharge current of up to 300 A.

Conclusion:If you require high current and high power output and can accommodate larger size and weight, the 24V 314Ah Ultra battery is the optimal choice.
