Akumulatory LiPo na egzamin

Co jest sprawdzane na egzaminie

LiPo batteries are one of the most frequently examined topics in both A1/A3 and A2 papers. ULC question bank items cover battery chemistry, charging procedures, storage and labelling — including cell count (S number), voltage and discharge rating (C rating).

You must be able to calculate battery voltage from the S number (e.g. 3S = 11.1 V nominal, 12.6 V fully charged) and understand what the C rating means during flight operations.

Zasady bezpieczeństwa na egzaminie

LiPo cells are thermally unstable when damaged, overcharged or deeply discharged. Exam questions cover: storage charge level, prohibition on unattended charging and the use of LiPo-safe bags.

Questions about damaged or puffy batteries appear frequently — the correct answer is always to remove the battery from service. Identify and avoid the 'continue using with caution' distractor.

How to prepare for the battery topic

The battery topic covers roughly 5–8% of all A1/A3 and A2 questions. Dedicate 2–3 focused study sessions to battery anatomy, charging, storage and disposal.

In A2STS, filter questions by the battery topic category and run 15–20 question sets. After every incorrect answer, read the full explanation before moving on.

Najczęściej zadawane pytania

Jaki jest prawidłowy poziom naładowania akumulatora LiPo?

Storage charge is typically around 3.7–3.85 V per cell — less than full charge (4.2 V) and more than a depleted state. The exact level is specified in your charger's instruction manual.

Co oznacza ocena C?

The C rating is the maximum continuous discharge rate as a multiple of capacity. For example, a 2000 mAh battery with a 25C rating can deliver up to 50 A (2 Ah × 25 = 50 A).
