Question 2

Which RC vehicles are compatible with this 18500 2S Li-Po battery?

                    This 18500 7.4V 1100mAh Li-Po battery is designed for Huanqi 960, Huanqi 747A, and compatible RC aircraft, speed boats, high-speed cars, and racing boats that use a 2S battery with SM-4P connector. Due to variations across different models, please verify your vehicle's battery compartment size (51×37×18mm) and connector type before purchasing.
                
            
                                
            
                
                    What is the difference between 1S, 2S, and 3S Li-Po batteries?
                    +
                

                
                    1S = 3.7V (single cell), 2S = 7.4V (two cells in series), 3S = 11.1V (three cells). This is a 2S battery, delivering 7.4V nominal voltage with 8.4V at full charge. Always use a 2S Li-Po balance charger for this battery. Never mix different cell counts in the same device. If you need a higher voltage for larger RC vehicles, consider a 3S battery, but check your device's voltage rating first.
                
            
                                
            
                
                    How long does this 1100mAh 2S battery last in my RC vehicle?
                    +
                

                
                    Actual runtime depends on your vehicle's power draw — motor size, propeller/paddle size, weight, and throttle usage. For a typical Huanqi 960 RC aircraft, you can expect approximately 8-15 minutes of flight time on a full charge. For speed boats, runtime may be 6-12 minutes depending on speed settings. Always carry spare batteries for extended sessions. For best performance and longevity, avoid completely discharging the battery (keep above 20%).
