Battery Health — The Number Most Sellers Won't Show You

A drone battery is a $150–300 consumable with a hard lifespan. We publish cycle counts and tested capacity for every pack we sell, so the hidden cost is never hidden.

Ask a marketplace seller for the battery cycle count and watch the listing go quiet. Yet a DJI intelligent battery is rated for roughly 200–400 cycles before capacity drops below 80% — meaning a "barely flown" drone can arrive with a pack that's effectively spent. At AST-Drones, battery data is tested, published, and covered by the warranty.

Why Capacity Matters More Than Cycles

Cycle count is a proxy; capacity is the truth. Two 60-cycle batteries can test at 96% and 83% depending on storage and charging habits — which is why every pack gets a physical capacity run, not just a chip read. The tested figure appears on your unit's report and anchors its warranty threshold.

Buying a drone for demanding work? Pair a warrantied airframe from the catalog with certified batteries — or ask about fresh-pack bundles at checkout.

Frequently Asked Questions

How do I check my own DJI battery cycles?

In the DJI Fly/GO 4 app: connect the drone, open battery settings, and the cycle count displays per pack. For a deeper read (cell voltages, health %), desktop tools like DJI Assistant 2 expose more. Our quote form links a step-by-step guide.

Is a 100-cycle battery worth buying?

Yes, if tested capacity holds ≥85% and the price reflects it — that's why Good-grade units cost 40–55% less. The trap is paying Excellent-grade money for a 100-cycle pack, which published reports make impossible here.

Are batteries warrantied?

Yes — if a pack drops below its grade's capacity threshold within the warranty window, we repair or replace it. Normal gradual aging over months is excluded.
