Question: Why can't my cellphone find the battery's Bluetooth?
Answer: The battery Bluetooth version is Bluetooth 4.0, please check the compatibility with your cellphone. If possible, please change to another cellphone for a try.
Question: Why can't my phone be connected to the battery's Bluetooth?
Answer: Firstly, we recommend the connection distance between the battery and the cellphone should be within 5 meters upon the initial connection test. If the Bluetooth cannot be found or connected, we suggest uninstalling the current "RoyPow Fish" APP and downloading it again from the APP store. Next, reinstall it and release all the required permissions for the "RoyPow Fish" APP. Lastly, make sure to turn on the cellphone's Bluetooth, and start the APP to reconnect it.

Question: Why can't I turn on the Wi-Fi in the APP?
Answer: If the connected PowerUrus battery is not a Wi-Fi version, the Wi-Fi in the APP will be disabled.
Question: Why is the battery's voltage too low at the first use?
Answer: Due to the logistics restriction, the battery only has 25~30% SOC before leaving the factory, we suggest recharging the battery completely before use, and the battery's voltage will become normal.
Question: Why does the battery SOC in the APP seem inaccurate?
Answer: If you just received the new battery or the battery hasn't been recharged for a long time, the battery SOC in the APP might be inaccurate, the SOC will be accurate after a circle of full charge and discharge.
Question: How many PowerUrus batteries can be connected in series or parallel?
Answer: The Maximum PowerUrus batteries can be up to 4 in series (48V Battery System) or 4 in parallel (12V Battery System). Please contact us first if you require PowerUrus batteries to be connected both in series and parallel.
Question: What gauge of cable should I need for my battery system?
Answer: As the cable size is affected by the cable length, cable current, the inverter power rating, and something else, so you have to check the total power consumption of the total electricity system and the operating voltage of the battery system (e.g. 12V / 24V / 36V / 48V battery system) first, and then you can roughly calculate the current in the battery system. Lastly, refer to the "Cable Sizing" chart in the "Welcome Guide" to select the corresponding cable gauge. You also can consult us for more advice on cable sizing.
Question: What's the PowerUrus batteries difference between the Standard Version and the Preheat Version?
Answer: The Standard Version has low-temperature charge protection and doesn't allow to be charged below 0℃, while the Preheat Version has a battery preheating function and allows to be charged below 0℃ without damaging the battery. They apply to different use scenarios.
Question: Can standard batteries be connected in series and parallel with Preheat batteries?
Answer: Not recommended. In case of severe cold weather below 0°C, the Preheat model can be charged while the standard model cannot be charged. If the two batteries are connected in series or parallel, the battery system will work abnormally.
Question: How does the Preheat battery work?
Answer: If the battery cell temperature is already below 0°C when charging the battery, after connecting to the charger, the charger will prioritize heating the battery to 16°C before charging the battery. If the battery cell temperature drops to 3°C again during the charging process, the charger will stop charging the battery and heat up the battery cell again until the cell temperature reaches 16°C, then the charger will charge the battery cell again. The cycle is repeated!
