Battery capacity: 64.75 Wh · Chemistry: li-ion
Racing drones demand batteries that can deliver consistent power across extended flight sessions, and the 5S li-ion configuration strikes an ideal balance for competitive pilots who need reliability without excessive weight penalties. This mid-range pack is purpose-built to handle the demanding discharge rates characteristic of gate racing and speed trials, maintaining voltage stability even during aggressive throttle inputs and rapid directional changes. Whether you're running timed laps or practicing maneuvers before an event, this battery's chemistry is engineered to sustain performance across multiple flights in a single day without the degradation you'd see in entry-level alternatives.
Proper charging discipline directly extends the lifespan of your li-ion pack, making it worth developing smart habits early. Store your battery in a cool, dry location between sessions—heat acceleration and humidity are the silent enemies of li-ion longevity—and avoid letting it sit fully charged for extended periods if you're not flying immediately. Inspect the pack regularly for any signs of puffing, discoloration, or damage to the case or connector pins; small issues caught early prevent catastrophic failures during high-speed flight. For racing pilots, treating your battery with the same meticulous care as your frame and electronics transforms it from a consumable into a reliable workhorse that can support a whole season of competitive flying.
With the fastest charger listed here (Fast charger, 120W) it takes about 46 min. With the slowest (Standard charger, 30W) it takes about 3 h 3 min. Mid-range 5S battery designed for drone racing events with balanced capacity and discharge rate for sustained high-speed performance.
Frequently asked questions
- How long does it take to charge a High-Performance Racing Drone Battery (5S, 3,500 mAh)?
- From 0% to 100% with the standard 60W charger, it takes about 1 h 31 min. Using a faster charger shortens that; using a weaker one extends it, see the table above for exact numbers.
- How often should I charge this battery if I'm flying multiple races in one day?
- Between heats, charge as soon as the pack cools to room temperature—this prevents thermal stress on the cells while ensuring you're always ready for the next race. Avoid charging a warm battery, as the internal resistance creates unnecessary heat buildup. For pilots running back-to-back events, having two or three batteries in rotation minimizes downtime and keeps each individual pack from experiencing excessive cycling stress on a single day.
- What's the best way to store this battery when I'm not racing for a few weeks?
- Store the 5S pack at partial charge in a cool location—ideally around room temperature or slightly below—rather than fully charged or completely depleted. A climate-controlled storage box or ammunition case works well to protect against humidity and temperature swings. Check the pack every couple of weeks and top it off if needed; li-ion cells naturally self-discharge over time, and storing them at a moderate state of charge minimizes chemical stress and maximizes the number of flight-ready cycles you'll get when the next racing season arrives.
- How is this charge time calculated?
- We divide the energy needed (64.75 Wh times the percentage you're charging) by the charger's effective power, which is the charger's wattage times the battery chemistry's real-world charging efficiency (85% for Lithium-ion (Li-ion / Li-Po)). The same formula powers both this page and our API.
