VIFLY WhoopStor 3 - White

VIFLY WhoopStor 3 1S Battery Charger and Storage Discharger BT2.0, PH2.0, XT60, USB-C (White)

The VIFLY WhoopStor 3 is a smart 1S battery charger designed for FPV whoop pilots and hobbyists who want more control, more convenience, and safer battery handling. It combines charging and storage discharging in one compact device, making it a great choice for everyday use at the bench or at the field. Just select your target voltage and the charger takes care of the rest automatically.

The built-in storage mode is one of the biggest advantages of the WhoopStor 3. Instead of leaving your 1S LiPo packs fully charged for too long, you can quickly bring them to the ideal storage voltage for better battery care and longer pack life. It is a practical solution for pilots who fly often and want to keep their batteries in top condition.

The color LCD screen and intuitive interface make operation simple and clear. Charging status is easy to read at a glance, so you always know what is happening with each battery. Whether you are a beginner in micro FPV or an experienced pilot, the menu is easy to navigate and quick to set up.

With an adjustable charge current from 0.3A to 1.3A, you can match the charging speed to different battery sizes and flying needs. This gives you the flexibility to charge smaller packs more gently or speed things up when needed. For best performance, batteries are ideally charged at around 2C.

The charger features 6 independent charging channels, so your batteries do not need to have the same voltage or capacity. You can charge different 1S packs at the same time and even unplug a fully charged battery while the others continue charging. This is a huge time-saver for regular whoop sessions.

Multiple power input options make the WhoopStor 3 easy to use almost anywhere. It supports USB-C, XT60, and DC input. The USB-C port supports PD and QC fast-charging protocols at 9V and 12V, but it does not support standard 5V USB charging.

The built-in memory function saves your last settings, so you do not need to reconfigure the charge current every time you power the charger on. There is also an audible buzzer alert to let you know when a charging cycle is complete, and if you prefer silent operation, the buzzer can be turned off manually.
