LiPo batteries are the heart of FPV performance. A bad choice can ruin a flying session or damage your drone. Here's everything you need to know.
Understanding the specs
Cell count (S)
Determines voltage:
- 3S (11.1V nominal) — small drones, whoops, micro quads
- 4S (14.8V nominal) — standard for 5" freestyle and racing
- 6S (22.2V nominal) — maximum performance, advanced 5" builds
Capacity (mAh)
How much energy it stores:
- 450–650 mAh — micro drones (2–3" props)
- 1300–1500 mAh — 5" freestyle (~4–5 min flight time)
- 2000–2200 mAh — 5" efficiency or heavier builds
C rating
How much current it can deliver: Max current = C × mAh
- A 1500mAh 100C pack delivers up to 150A
- For 5" freestyle, aim for at least 75–100C
Never discharge a LiPo below 3.5V per cell or it will be permanently damaged. Most flight controllers have minimum voltage protection — configure it.

Essential LiPo safety
- Store at 50% charge (3.8V per cell) if not flying for more than a week
- Never charge a hot battery — wait 15 min after flying
- Discard puffy/swollen batteries — they are a fire hazard
- Always use a LiPo-safe bag when charging
- Recycle properly — never throw in regular trash
