Now with per-cell monitoring, 90 days of history and alerts that reach you before your battery goes flat.
Fogstar Drift is the companion app for Fogstar's Drift range of LiFePO4 leisure batteries. Connect over Bluetooth and see exactly what your battery is doing — at home, on the road, or at the campsite.
LIVE MONITORING
State of charge, voltage, current, power and temperature the moment you open the app. A clear gauge shows what's left, and an estimate tells you how long it will last at the current draw.
EVERY CELL, NOT JUST THE PACK
Most monitors show one number. Fogstar Drift shows every cell, with the spread between highest and lowest in millivolts. A cell drifting out of balance is the earliest warning you get — long before the battery lets you down.
HISTORY THAT GOES BACK
Up to 90 days of charge, voltage, current, temperature and cell data, recorded automatically. Scrub back through any period, see exactly when a protection tripped, and export it all to CSV.
ALERTS
Your own thresholds for low charge, high and low temperature and protection events, with quiet hours so nothing wakes you at 3am. Winter guard warns you when a pack is too cold to charge safely.
BANKS
Running packs in parallel? Group them and see the whole system totalled on one screen, or drill into any single pack.
TOOLS FOR REAL INSTALLS
Battery recovery for a pack that won't wake, a timestamped event log of every connection and protection, read-only BMS thresholds, and a Report a Problem button that sends a full diagnostic bundle to Fogstar support.
PRIVACY
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 a Bluetooth BMS.
Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
A completely rebuilt Fogstar Drift app: new dashboard, per-cell balance view, 90 days of history with CSV export, configurable alerts with quiet hours, bank support for packs in parallel, and recovery tools for packs that won't connect.
If you used the previous app you'll need to add your batteries again — it takes a few seconds per pack.
