The BetaFPV LAVA 1S 260mAh 80C battery is a 3.8V LiHV pack with a BT2.0 connector for 1S tiny whoops and micro quadcopters, sold as a pack of 5.
The listing says it is 1.1g lighter and smaller than the LAVA 1S 300mAh model, which helps the drone's centre of gravity, and that a Z-folding process gives a 5% energy density upgrade over standard winding.
An 80C discharge rate gives strong burst power, and the pack is designed for a longer cycle life.
260mAh, 0.98Wh: light 1S LiHV cell.
80C discharge: enhanced burst power.
1.1g lighter than the 300mAh LAVA: better centre of gravity.
Z-folding process: 5% energy density upgrade.
BT2.0 connector: low-resistance whoop connector.
Pack of 5: spares for a session.
A 1S whoop battery is a single lithium cell with a small connector. HV (LiHV) versions can be charged to 4.35V per cell instead of 4.2V, which stores a little more energy, but they must be charged with a charger set to the HV mode and the correct current. A high C rating shows that the pack can deliver high burst current, which matters for the small brushless motors in tiny whoops.
The connector is part of the performance: a lower-resistance connector wastes less power as heat and reduces voltage sag under load. Match the connector to your drone (BT2.0 here) and never force it in the wrong way round.
Small packs are easy to damage. Charge them at no more than 1C unless the maker states otherwise, never charge a puffed or dented cell, and store them at about 3.8V. A voltage tester or a low-voltage alarm helps you land before the cell is over-discharged.
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.
