Production Flow of Drone Battery

Open packaging and sort materials.

Full inspection of grouped cells for defects: leakage, scratches, dents, punctures, swelling, improper foam alignment (exposed tabs or missing bottom foam).

Measure cell voltage and internal resistance; screen and rebalance cells with excessive deviations.

Trim electrode tabs to specification using a tab-cutting machine.

Weld tabs with an ultrasonic welder and trim to ensure flush alignment.

Trim tabs flush with weld points and press flat onto foam padding.

Solder wires using an electric iron.

Place kraft paper for insulation and cover with high-temperature adhesive tape.

Install battery module into casing per assembly specs and connect wiring.

Connect module to charger, switch to standard voltage mode, activate slow charge, and initiate charging.

Apply sealant to screw holes, install groove-down silicone plugs, and reinforce sealing at designated points.

Verify communication, output voltage, temperature sensing, discharge curves, and leakage.

Inspect for scratches, adhesive residue, stripped screws, and ensure labels are legible/undamaged.

Label units, place in foam-lined boxes, seal in PE bags with desiccant, and secure with top foam padding.

Box approved units and dispatch.

FAQs
Drone batteries must align with mission-specific demands:
-
Agricultural Spraying Drones: Require high-capacity batteries (8,000mAh+) for extended operation, paired with fast-charging capabilities, high-current discharge, and lightweight design.
-
Aerial Photography Drones: Prioritize compact, lightweight pouch-type polymer Li-ion batteries with extended flight time.
-
High-Speed Acrobatic Drones: Demand high discharge-rate batteries to sustain rapid acceleration bursts and stable power output.
-
Security/Mapping/Firefighting Drones: Focus on batteries with long endurance, temperature resilience, and durability across repeated cycles.
Reduced Performance in Cold Weather
-
Pre-warm batteries before use.
-
Limit flight time to half of normal duration in low temperatures.
-
Raise voltage alarm thresholds to prevent premature shutdowns.
Short Circuit Risks
-
Transport batteries in explosion-proof cases.
-
Avoid simultaneous contact of tools with positive/negative terminals during maintenance.
Casing Damage
-
Handle with care; secure straps before flight.
-
Retire batteries immediately if outer layers are compromised.
Mixing Batteries/Improper Charging
-
Never combine old and new batteries.
-
Avoid parallel charging of mismatched battery models.
Charging Protocol
-
Use manufacturer-approved chargers.
-
Prevent overcharging; perform balance charging periodically.
Storage Guidelines
-
Maintain 40-60% charge for long-term storage.
-
Store in a cool, dry environment (15-25°C / 59-77°F).
Usage Precautions
-
Avoid deep discharges (never drain below 20%).
-
Inspect for swelling, leaks, or damage post-flight.
Protective Measures
-
Keep batteries dry and shielded from corrosive substances.
-
Clean contacts and surfaces after each mission.
