FAQ

• Q1. What is the safety level of lithium batteries?

  Our lithium iron phosphate (LiFePO₄) batteries are considered very safe and are not prone to combustion or damage, thanks to their chemistry and mechanical advantages.
  They can also withstand harsh conditions, whether under severe pressure or extreme temperatures. When exposed to hazards like short circuits or overheating, they will not ignite or catch fire, significantly reducing the risk of any damage.
  If you are selecting batteries for use in potentially hazardous or unstable environments, lithium iron phosphate is likely the best choice. They are non-toxic, non-polluting, and environmentally friendly, making them a safe and reliable option.

• Q2: What is a Battery Management System (BMS)? What is its function and where is it used?

  A:BMS (Battery Management System) is a system that acts as the bridge between the battery and the user. It ensures the safe operation of the battery by protecting it from over-voltage, over-current, and overheating. The primary function of the BMS is to monitor the battery's state and prevent safety issues such as short circuits or overcharging. All rechargeable batteries are equipped with a BMS to manage and resolve these potential risks.
  In electric vehicle batteries, the BMS is designed with cutting-edge technology and innovation. Key features include:Remote monitoring via OTA (Over-the-Air updates).Thermal management and multiple protection mechanisms, such as preventing low-voltage protection and overcharging.

• Q3: What is the expected lifespan of the battery?

  A: The battery can be used for approximately 4,000 charge cycles. The battery is designed for a lifespan of around 10 years, and we provide a 5-year warranty. Therefore, even though the initial cost of LiFePO₄ batteries is higher, they offer savings of up to 70% on battery costs over a 5-year period.

• Q4: What are the applications of lithium batteries?

  A:Our lithium batteries are widely used in electric vehicles, golf carts, high-altitude platforms, cleaning machinery, and more. We specialize in lithium batteries with a lifespan of over 10 years, making us experts in the field of advanced lithium-ion technology. Additionally, they can be used in energy storage solutions for your home or as a power source for your electric vehicle.

• Q5: I want to switch to lithium iron phosphate batteries. What do I need to know?

  A: When upgrading to lithium iron phosphate (LiFePO₄) batteries, you need to consider factors such as power requirements, efficiency, and size, and ensure that you have the appropriate charger. (If you already have a charger with sufficient power, your battery performance will be even better.)
  Please note that when upgrading from lead-acid batteries to LiFePO₄, you can reduce the size of the battery (it can be up to 50% smaller in some cases) while maintaining the same operating time. Additionally, it is important to understand that this upgrade could involve adjustments to your vehicle’s equipment.
  If you need assistance with the upgrade process, please contact our technical support team. They will be happy to help you choose the best battery for your needs.

• Q6: Can the battery be used in cold weather?

  A: Our batteries can operate in temperatures as low as -4°F (-20°C). They are equipped with a self-heating function (optional) and can be charged even in cold conditions.

• Q7: How should the battery be charged?

  A: Our lithium battery technology uses the most advanced internal battery protection system to prevent battery damage. We recommend selecting a high-quality, energy-efficient charger to ensure the maximum safety of your battery.

• Q8: Can lithium batteries be charged at any time?

  A: Yes, lithium batteries can be charged at any time without causing damage. Unlike lead-acid batteries, lithium batteries do not suffer from memory effect. This means users can charge the battery at any point during the day or night without affecting its performance, allowing for continuous use without overcharging.

• Q9: If I need to replace the battery, do I need to use the same charger?

  A: Please note that our original battery is designed to work with our specified chargers for optimal performance. If you choose to use your original charger for a different battery, it may not be compatible and could potentially damage the battery. We cannot guarantee that third-party chargers will safely charge the battery. Our technical team strongly recommends using our provided charger to ensure proper functionality and safety.

• Q10: Can I use the battery charger every time I use it?

  A: No, you should only charge the battery after a few cycles of use, ideally every couple of weeks. We recommend keeping the battery's "main switch" turned on for at least 5 hours to allow for optimal storage, ensuring it can last up to 8 months without issue.

• Q11: What is the charging method of the charger?

  A: Our charger uses a constant current-constant voltage (CC-CV) charging method. Initially, the charger provides constant current to charge the battery. Once the battery reaches its rated voltage, the charging current reduces to 0.02C to complete the charging process.

• Q12: Why is the charger unable to charge the battery?

  A: First, check the charger's indicator light. If the light is not on, please connect the charger to the power supply. When the light shows a steady green, please check if the DC cable is properly connected to the battery terminals. If everything appears to be normal but the issue persists, please contact RoyPow customer service for further assistance.

• Q13: Why does the charger show a red light when charging?

  A: Please first check the DC cable (with NTC thermistor) to ensure it is properly connected. If the connection is fine, the red light may indicate a temperature-related warning, meaning the charger has detected a temperature issue.
