How to read the values

Flight score — the result of a simulated flight on the discharge rig. Every battery of the class flies the same flight, consuming 84 % of its label capacity. The 0–100 score combines the weakest cell's sag at both punches, the minimum in the punch block, the mean voltage under load, the energy lost during the flight and the temperature rise. A battery the rig cut off during the flight did not finish and has no score (DNF).

Losses during the flight — energy turned into heat instead of thrust during the simulated flight, computed with the same balance as the heat losses: the area between the reference curve and the flight curve over the delivered charge. Lower is better.

Energy density — the reference-discharge energy per kilogram of battery mass including leads and connector. Higher is better – on small batteries every gram counts, on a whoop one gram is 5–8 % of the all-up weight. A higher energy density usually goes hand in hand with lower load capability, so read it together with the voltage under load (1S) or the continuous C (multi-cell packs).
