This 8-piece set of BetaFPV BT2.0 300mAh 1S 30C HV LiPo batteries powers micro FPV drones, tiny whoops and micro quadcopters, with discharge rates up to 30C for racing and freestyle.
The BT2.0 connector reduces internal resistance with 1.0mm banana connectors and supports 9A continuous and 15A burst current. The listing says it is more durable than PH2.0 crimped pins.
It achieves roughly 2 minutes of full-throttle flight, and the page showed low stock when it was read.
300mAh 1S: a micro-drone pack.
30C/60C: 9A continuous and 15A burst.
BT2.0 connector: 1.0mm banana connectors, lower resistance.
Improved voltage sag: more efficient discharge.
More durable than PH2.0: than crimped pins.
Pack of 8: a full set of spares.
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.
