Are Li-Ion batteries better than LiPo for long range?

Often yes. Li-Ion cells offer 250–300 Wh/kg vs 180–220 Wh/kg for LiPo, and they handle the low C-rate discharge of long-range cruise far better.

How do I estimate flight time from battery capacity?

Use the Flight Time Calculator. Enter motor efficiency, prop diameter, and all-up weight. A rough rule: divide mAh by average amp draw in milliamps, then multiply by 0.8 (practical efficiency factor).

Can I use two batteries in parallel for long range?

Yes — parallel packs are common on long-range builds. Use a parallel adapter and ensure both packs are matched in capacity and state of charge before connecting.

Best Batteries for Long Range (2026)

Long-range battery selection prioritises energy density and internal resistance consistency over peak discharge rate. Packs of 3000 mAh and above on 4–6S systems provide the energy stores needed for 20–40 km missions. Li-Ion packs deserve serious consideration here — their superior energy density and longer cycle life often outweigh the lower peak discharge capability for low-current cruise applications.

Long-range missions are entirely energy-budget-constrained — maximising mAh per gram is the single most impactful spec to optimise.
