Background: The Challenge of Cold-Weather Flight
Flying a drone in extreme cold is no small feat. The biggest obstacle? Battery performance. In temperatures between -10°C and -20°C, most consumer drones simply can’t take off, let alone maintain stable flight or capture consistent footage. For skiers, mountaineers, and polar explorers, this has long been a major limitation.
To address these sub-zero challenges, HOVERAir specifically designed a cold-optimized Power System for the X1 PRO and PROMAX. This system ensures smooth takeoffs, stable flight, and reliable performance even in snowy, icy conditions.
While we’ve previously introduced the basic power accessories for the X1 PRO and PROMAX, today we’ll take a closer look behind the scenes at the technology that keeps these drones flying even in freezing temperatures.
Thermo Smart Battery — Intelligent Cold-Weather Power
Operating temperature: -4°F (-20°C) to 113°F (45°C)
Charging and discharging temperature: -4°F (-20°C) to 113°F (45°C)
Weight: 64g
Key Features:
The Thermo Smart Battery is ultra-light and thin, yet it packs a built-in micro temperature control system. When the surrounding air is too cold, the battery automatically warms itself to the optimal operating temperature—no user intervention required. This is what HOVERAir calls a “user-free intelligent thermal adjustment”, letting you focus on flying instead of battery management.
The battery cells themselves use a custom high-energy chemistry designed for peak output while keeping weight minimal. Even with the additional temperature control module, the cold-weather battery is only 1g heavier than the standard smart battery for the X1 PRO and PROMAX, preserving excellent flight performance.
PowerCase — Portable Charging for Extreme Cold
Recommended operating temperature: -4°F (-20°C) to 86°F (30°C) The Thermo Smart Battery ensures the drone can fly in sub-zero temperatures—but HOVERAir didn’t stop there. The PowerCase is a portable charging station designed to function in temperatures as low as -20°C, keeping your drone powered and ready.
Why it stands out:
- Extra flight time: The PowerCase can provide about 40 minutes of additional flight, letting you recharge on the go. It’s the perfect “charge anywhere, anytime” solution for winter adventures.
- Cold-resistant battery cells: Inside, a specially designed low-temperature battery can still deliver over 80% of its power even at -20°C—a level of performance standard power banks can’t match in freezing conditions.
- Smart charging process: With the included mini adapter, simply place the drone into the PowerCase and close the magnetic lid. Within seconds, the battery begins fast charging automatically, no extra steps required.
- Compact and convenient: The PowerCase features a magnetic lid for easy, secure closure, and a transparent window for monitoring charging progress at a glance. A built-in Type-C port supports both fast charging and emergency power for devices such as smartphones, and it works reliably even in extreme cold.
Pro tip: For the best experience, store your drone inside the PowerCase when not flying. This keeps the drone warm and ready. If the drone is left outside the PowerCase, it may need 1–3 minutes to reach flight-ready temperature.
Tips for Flying in Cold Weather
To enjoy a safe and stable flight in extreme cold, HOVERAir recommends:
- Fly with fully charged batteries.
- Keep batteries warm, ideally in the PowerCase or a thermal pouch.
- Apply snow protection stickers to prevent snow entering the drone body.
- If the propellers are icy, wipe them dry before takeoff.
- Avoid contact of battery metal parts with water.
Compatibility Notes
Q: Can the PowerCase charge X1 PRO &PROMAX smart batteries?
A: Yes, but smart batteries lack temperature control. In extreme cold temperatures, they may fail to charge properly. For the best cold-weather experience, HOVERAir recommends using the Thermo Smart Battery.
By combining the Thermo Smart Battery and PowerCase, HOVERAir offers a truly all-temperature flight experience. Whether you’re soaring over snow-capped mountains at -20°C or exploring a hot desert at 45°C, the X1 PRO and PROMAX deliver reliable performance—allowing creators to capture every moment, no matter the weather.
