This product's shell is made from imported PC material, boasting high transmittance, drop resistance, and impact resistance. Ideal for fixed-wing aircraft, drones, and other environments. The lighting system is designed to mimic navigation lights, enhancing your aircraft's visibility and realism. Easy to install and use, even for beginners. Widely applicable in electric airplanes, helicopters, and aircraft – a great choice for aviation enthusiasts. Battery: Li-poly 85mAh Tips: Upgraded to 4 flashing modes: Double flash, fast flash, safe flash, and breathing light mode. Charger upgrade (reduced charging time). The product uses a high-quality polymer lithium battery with low-voltage protection, effectively extending battery life. Charging: The red light indicates charging, and the blue light indicates full charge. The original charger can be used with USB and power banks. With the original charging conversion cable, you can use a model aircraft balance charger (requires a single-chip battery charging function, like A6, PL8, etc.). If the navigation light doesn't illuminate for an extended period and the battery voltage is too low, use the original charger. If the charging cable is accidentally connected in reverse, the red light on the charger will also illuminate. Short-term reverse connection won't damage the aircraft lights, but it will cause the electronic components to heat up (the battery won't be damaged or heat up). Long-term reverse connection will damage the aircraft light components. Special Note: Pay attention to the positive and negative poles when charging, or the equipment will be damaged.
