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 β€’ State of charge, voltage, current and power β€’ Remaining capacity, cycle count and temperatures β€’ Whether the battery is charging, discharging or resting CELLS β€’ Every cell's voltage, the spread between highest and lowest, and when the BMS is balancing β€’ A cell drifting out of balance is the earliest warning you get – long before the battery lets you down HISTORY β€’ Readings recorded automatically while you're connected β€’ Charts of charge, voltage, current and temperature over hours, days or months β€’ Up to 90 days kept on the phone; export it all to CSV ALERTS β€’ Low charge, high or low temperature, winter guard and protection trips β€’ Set your own thresholds and quiet hours, so nothing wakes you at 3am MORE β€’ Multiple batteries and battery banks in one app – see the whole system totalled, or drill into any single pack β€’ Tools for real installs: battery recovery for a pack that won't wake, connection diagnostics and a timestamped event log β€’ 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.
