Fogstar

About this app

Fogstar Drift is the companion app for Fogstar Drift lithium (LiFePO4) leisure batteries. It connects to your battery over Bluetooth and shows you exactly what it's doing – at a glance on the dashboard, in detail down to each cell, and over time in History. LIVE DASHBOARD • State of charge, voltage, current and power • Remaining capacity, cycle count and temperatures • Whether the battery is charging, discharging or resting CELLS • Every cell's voltage, the spread between highest and lowest, and when the BMS is balancing • A cell drifting out of balance is the earliest warning you get – long before the battery lets you down HISTORY • Readings recorded automatically while you're connected • Charts of charge, voltage, current and temperature over hours, days or months • Up to 90 days kept on the phone; export it all to CSV ALERTS • Low charge, high or low temperature, winter guard and protection trips • Set your own thresholds and quiet hours, so nothing wakes you at 3am MORE • Multiple batteries and battery banks in one app – see the whole system totalled, or drill into any single pack • Tools for real installs: battery recovery for a pack that won't wake, connection diagnostics and a timestamped event log • Report a problem in one tap – the app sends Fogstar a full diagnostic bundle with a reference number, so we can help without the back-and-forth PRIVACY No ads, no tracking. Everyday monitoring is Bluetooth only – your battery's data never leaves your phone unless you send a support report. Cloud features run on Amazon Web Services in Europe. Works with Fogstar Drift batteries fitted with the Bluetooth module. If anything isn't right, use Report a problem in Settings and we'll take a look.

New Navy theme: a softer, blue look that's easier on the eyes than true black - and it stays navy day and night. Settings → Appearance & language → Theme → NAVY. When the app can't reach a battery, it now tells you the likely reason and the fix instead of a blank "could not connect" - and if you try to pair something that isn't a Drift leisure battery (like a Fogstar Energy home battery), the app now explains that properly instead of failing silently. Fixed: CSV export from History now works on iPad. Fixed: the QR scanner no longer crashes if camera access was previously declined. Fixed: the app occasionally asking for your Bluetooth PIN out of the blue - some BMS modules reject a correct PIN once on a weak signal. The app now retries on a fresh connection and only asks if the battery rejects it twice in a row. Also corrected the PIN prompt: your PIN is on the card that came with the battery (printed on top on later models).

Momentum comes from crawler snapshots for the tracked storefront. “Viral growth signal” means unusually fast recent rating gains; it is an indicator, not download data.
