VIFLY WhoopStor 3 Battery Charger – 1S Battery Charger from the VIFLY brand – a compact, lightweight, and functional solution for fast and safe maintenance of 1S Li-Po batteries for whoop and mini-drones. The WhoopStor 3 combines the capabilities of a standard charger with a function for preparing batteries for long-term storage, preserving their characteristics and extending their lifespan.

Key Advantages

This charger is equipped with a bright LCD screen, an intuitive interface, and remembers the last settings. The WhoopStor 3 allows discharging batteries to safe storage voltage values – 3.80 V or 3.85 V – and supports charging current adjustment in the range of 0.3 A to 1.3 A per port, which allows adapting the process to different battery capacities. The presence of six independent channels ensures simultaneous charging of multiple batteries with the ability to individually connect and disconnect each port when the battery is ready.

VIFLY WhoopStor 3 Functions

Charges and Prepares for Storage

The storage function discharges the battery to a set safe voltage for long-term storage, preventing cell degradation during prolonged inactivity.

Variety of Power Sources

The device supports power via USB-C (PD3.0) with PD and QC protocols for fast charging from 9 V and 12 V, and has XT60 and DC (5.5×2.1 mm) inputs, making it compatible with various battery types and adapters (XT60 2S-6S, DC).

Efficient Charging Speed

Adjustable charging current of 0.3–1.3 A per port provides flexibility: you can set the optimal current for a specific battery capacity. You can disconnect a ready battery and connect the next one without stopping the charging process on other ports.

Six Separate Channels

Six independent ports allow simultaneous servicing of up to six 1S batteries with individual control over each channel.

Bright Display and Additional Conveniences

The high-quality LCD display clearly shows the charging status of each port, and an audible alert will notify you when the charging process is complete (it can be turned off). The device remembers the last settings, saving time during subsequent sessions.
