Vifly StoreSafe is an easy and practical way to discharge batteries to Storage voltage. If you leave batteries charged for a long time, they age faster and lose their desired performance. Most chargers can discharge the batteries, but it takes a long time and all the while the charger fan is humming annoyingly.
StoreSafe has a built-in temperature sensor, a passive cooler and an intelligent algorithm that changes the discharge rate depending on the battery voltage and cooler temperature. Just plug in the Lipo battery and that's all you have to worry about. StoreSafe automatically detects the number of battery cells and starts discharging the battery automatically at 3.85V per cell. When the battery reaches the desired voltage, the discharge is complete. This way you can leave StoreSafe connected to the battery without having to constantly check the battery status for fear of over-discharging it.
