VIFLY WhoopStor 3 – Smart 6-Port 1S Battery Charger for Tiny Whoop FPV Drones

The VIFLY WhoopStor 3 is a smart 1S battery charger specifically designed for Tiny Whoop FPV drones, combining charging, discharging, and storage charging functions in a single compact device. With six independent charging ports, multiple power input options, and an intuitive user interface, it has become one of the most popular chargers among Tiny Whoop pilots. Whether you’re flying at home, racing, or out in the field, the VIFLY WhoopStor 3 keeps your batteries in optimal condition and ready for the next flight.

Six Independent Charging Channels

Unlike traditional parallel chargers, the VIFLY WhoopStor 3 features six completely independent charging channels. This means your batteries do not need to have the same voltage or capacity, as each battery is monitored and charged individually.

In practice, this allows you to remove a fully charged battery and connect another one without interrupting the charging process for the remaining batteries. This design makes charging safer, more flexible, and far more convenient, especially when working with multiple 1S batteries of varying age and condition.

Charging, Discharging, and Storage Mode in One Device

One of the biggest advantages of the VIFLY WhoopStor 3 is its ability to charge batteries, discharge them, or automatically bring them to storage voltage. Storage mode is essential for extending the lifespan of LiPo and LiHV batteries, particularly when they will not be used for an extended period.

The charger supports four target voltages: 3.80 V, 3.85 V, 4.20 V, and 4.35 V. When storage mode is selected, the charger automatically determines whether the battery needs to be charged or discharged to reach the correct voltage. This simplifies battery maintenance while helping preserve long-term battery performance.

Compatible with PH2.0 and BT2.0 Batteries

The VIFLY WhoopStor 3 supports both PH2.0 and BT2.0 connectors, covering the vast majority of today’s Tiny Whoop 1S batteries. This allows you to use the same charger with batteries from different manufacturers without requiring additional adapters.

The charger is compatible with both standard LiPo batteries with a maximum voltage of 4.20 V and LiHV batteries with a maximum voltage of 4.35 V, allowing you to select the appropriate charging mode for each battery type.

Bright Full-Color LCD Display

A clear full-color LCD display on the front of the charger provides all essential charging information in real time. Users can monitor the voltage of every connected battery, charging current, selected target voltage, and charging status at a glance.

The simple two-button interface makes it quick and easy to adjust charging current or target voltage and start charging or discharging without navigating complicated menus. An optional audible notification can also be enabled or disabled to indicate when charging has been completed.

Flexible Power Input Options

The VIFLY WhoopStor 3 offers multiple power input options for maximum flexibility. It can be powered through XT60, DC 5.5 × 2.1 mm, or USB-C Power Delivery (PD3.0), making it equally suitable for use on a workbench or out in the field.

Using the XT60 or DC input, the charger accepts 6–26 V, allowing it to be powered by a 2S–6S LiPo battery or a suitable DC power supply. Through USB-C, it supports 9–20 V USB Power Delivery, with a 40 W PD power adapter recommended for maximum charging performance.

Higher Charging Current and Memory Function

Compared to the previous generation, the VIFLY WhoopStor 3 offers a higher maximum charging current of up to 1.3 A per charging port. This enables faster charging of higher-capacity 1S batteries while maintaining precise charging control.

The charger also remembers the last-used settings, eliminating the need to repeatedly configure charging current and target voltage every time it is powered on. This significantly improves convenience during everyday use.

Technical Features

The VIFLY WhoopStor 3 measures 108 × 55 × 30 mm and weighs approximately 140 grams, making it compact and easy to carry to every flying session. It features XT60, DC 5.5 × 2.1 mm, and USB-C PD3.0 power inputs, operating from 6–26 V via XT60 or DC, or 9–20 V via USB-C Power Delivery. A minimum 40 W input power supply is recommended. The charger delivers up to 1.3 A charging current per port, offers a maximum 1.1 W discharge power per port, and supports both PH2.0 and BT2.0 connector-equipped 1S LiPo and LiHV batteries. Storage voltages of 3.80 V and 3.85 V are available depending on the selected battery chemistry.

Why Choose the VIFLY WhoopStor 3?

If you fly Tiny Whoop FPV drones, the VIFLY WhoopStor 3 is one of the best solutions available for charging and maintaining 1S batteries. Its six independent charging channels, automatic storage mode, charging and discharging functions, PH2.0 and BT2.0 compatibility, full-color LCD display, and versatile power input options make it a practical and highly reliable charger for both beginners and experienced FPV pilots.

Thanks to its intelligent functionality and high-quality construction, the VIFLY WhoopStor 3 helps extend battery life, reduce charging time, and make every flying session more efficient and enjoyable.
