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
If you notice significantly reduced flight time, power drops, or unexpected shutdowns, or see bulging, damage, or abnormal charging, the battery is likely aged and should be replaced.
It’s not recommended. Voltage levels, discharge curves, and connector designs may differ between brands. Mixing batteries can cause instability or damage. Always use original or certified compatible batteries.
