Commercial Drone Battery Cycle Auditor

At the datasheet rating point, LiPo cells of this class are typically rated around the default shown (to 80% remaining capacity). Cycle at a shallower depth of discharge and the count rises steeply — that is the (DoD_rated/DoD)^k term. Heat, fast charging and storage at full charge all shorten it.

Because pack failure in flight is an airframe loss: insurers, and many aviation authorities' ops manuals, expect demonstrable battery lifecycle control — cycle counts, retirement criteria and storage practice. A per-pack log like this one (pack serial in the name, cycles and DoD per sortie) is exactly the artefact an audit or claims assessor asks for after an incident.

Count equivalent full cycles: two 50% discharges ≈ one full cycle of energy throughput. If your charger or BMS reports total Ah or kWh throughput, divide by the pack's rated capacity to get equivalent full cycles — that is the number to enter as cycles completed.

Industry convention is 80% of original capacity — beyond that, fade accelerates and runtime becomes unpredictable. Fleets usually retire packs at 80% for the duty they were bought for, then cascade them to lighter duty rather than scrapping immediately.

Yes — it is the single biggest lever you control. Lead-acid cycled to 50% instead of 80% roughly doubles cycle count; lithium chemistries gain similarly with the exponent k shown in the formula. Sizing a pack so daily use is a shallower fraction of capacity is usually cheaper than replacing packs early.
