How a LiPo battery works

A LiPo (lithium polymer) drone battery stores energy in cells connected in series. The S number is the cell count, and each cell has a nominal voltage of 3.7V, so a 6S pack is 22.2V. Capacity in mAh tells you how much energy the pack holds, and the C rating tells you how much current it can deliver: multiply the C rating by the capacity in amp-hours to get the continuous current.

Match the pack to your aircraft. The voltage must suit your ESCs and motors, the connector must match your power system and the pack must be able to deliver the current that the propulsion system draws at full throttle. A pack that is asked for more current than its rating will heat up and lose life.

Handle LiPo batteries with care. Charge them with a balance charger set to the correct cell count and current, never leave them charging unattended, store them at a partial charge, never use a swollen or damaged pack and transport large packs in a fire-resistant container. Large packs also weigh a lot, so lift and mount them securely.

Log how each pack behaves over time. Note the resting voltage after a flight, how warm the pack is and how much capacity the charger puts back in. A pack that heats up more than usual, sags sooner or shows one cell drifting away from the others is telling you that it is ageing, and it should be retired before it fails in the air. Label your packs so you can rotate them evenly.
