BattDeck

BattDeck is a simple offline battery pack tracking app.

The app helps you quickly see the status of each pack, its voltage, approximate charge percentage, type, active status, and usage order.

Key features:

• list of battery packs;
• name of each pack;
• pack type;
• voltage input;
• automatic charge percentage calculation;
• color indication of charge status;
• active pack marking;
• minimum and maximum voltage settings;
• JSON data import and export;
• local data storage on the device.

BattDeck does not require an account, internet, cloud sync, or server. All data is stored locally on the user's device.

JSON import and export allow you to manually transfer or transfer battery pack information between devices.

The application is designed for quick field use, when it is important not to mix up kits, see the current charge, and maintain the order of battery use.
