Li-ion

Buying guide: Li-ion

Li-ion packs, typically built from 18650 or 21700 cells, give the most flight time per gram for long-range cruising, at the cost of lower peak current. Check the pack's continuous discharge rating against your motors' draw. Lithium batteries ship by ground courier only.
