Drone Soccer

Soccer drones are essentially mini-quadcopters enclosed in a lightweight spherical frame, enabling safe mid-air collisions and easy identification via onboard LED lighting. Class 20 drones feature a 20 cm ± 1 cm cage and weigh under 110 g (battery and receiver excluded), while Class 40 drones use a 40 cm ± 2 cm cage and weigh up to 785 g excluding power equipment. Both classes employ four-motor electric propulsion and 2.4 GHz RC control, with full-contact play allowed within netted indoor arenas or suitably protected outdoor fields World Air Sports Federation.

Matches are split into three sets of three minutes each, with a brief maintenance interval between sets for drone repairs or battery swaps World Air Sports Federation. Each team fields five pilots but only one designated “striker” may score by flying through the opponent’s elevated goal ring (30 cm inner diameter for Class 20; 60 cm for Class 40). Victory is determined by winning two sets, with sudden-death overtime if tied. Drone balls must include fail-safe devices, LED identification capable of at least four colors, and obey strict weight/size tolerances (± 1 % measurement accuracy) World Air Sports Federation.

●Voltage & Cell Count

Pack voltage: 3 S or 4 S LiPo only, with 4 S nominal ≤ 17.0 V (no-load).

Cells per pack: 3 S (11.1 V) or 4 S (14.8 V) configurations; 4 S gives higher top speed at the cost of slightly more weight.

●Voltage per Cell

Max cell voltage: 4.25 V fully charged; storage voltage: ~3.85 V per cell.

●High Discharge Rate (C-Rating)

Class 20: ≥ 75 C continuous for instant throttle response in compact frames.

Class 40: ≥ 95 C (often 120 C) to sustain heavier loads and longer hover times.

●Capacity

Class 20: 650 mAh (4 S) or 850 mAh (3 S) recommended (≈ 2–3 min flight).

Class 40: 3 000–4 500 mAh typical (e.g. 3 000 mAh 4 S ECOFLUX for ~6 min hover).

●Weight & Size Tolerance

Pack weight & dimensions must be within ± 1 % of declared values, per FAI F9A tolerances.

●Connectors

Class 20: XT30 main connector;

Class 40: XT30 or XT60 (more common for higher current);

adapters (XT30⇄XT60) are widely available for flexibility.

●Safety & Durability

Fail-safe & protection: pack must include over-voltage cutoff or auto-shutoff; robust hard-case to withstand midair collisions.

Handling: follow LiPo safety best practices (storage, charging in fire-safe bag, supervised charging).

Founded in 2012 under the Grepow umbrella, Tattu was created to supply professional-grade LiPo power to the drone, FPV, and modeling hobby markets. With global offices in the US, Germany, and China, we support fast distribution and responsive technical service worldwide
