- Fixed some batteries getting stuck connecting and disconnecting every few seconds. The app now recognises when a battery is refusing the unlock and recovers properly — correcting the address it uses, or asking for the PIN — instead of looping.

- Fixed iPhone not being able to add certain batteries (including 48V models) that it could see but couldn't finish connecting to. They now connect automatically.

This update clears a false fault warning on some older batteries and makes them easier to connect to. - Some older batteries showed a red "Charge circuit fault" warning when the battery was actually healthy. That false alarm no longer appears — these batteries now read correctly and connect with full control. - Fixed some batteries rejecting the correct Bluetooth PIN — even the default — and refusing to unlock. The app now works out the right unlock for those batteries automatically. - You can now set a Bluetooth PIN on a battery that doesn't have one, not just change an existing one. - If your phone can't find a battery to add, you can now type its address from the label and pair it that way. - Replies from our support team now show on the main screen, so a reply to your report is easy to spot. - iPad: the app stays full-screen and fits properly — the gauge and graphs no longer stretch out of shape. - Fixed the charge and discharge switches showing the wrong state on some batteries. - Fixed a crash that could happen when the Bluetooth connection dropped mid-reading.

This update fixes a problem where some batteries could reject their Bluetooth PIN — even the correct one — and refuse to unlock. The app now works out the right unlock for those batteries automatically, so they connect as they should. Also in this release: - iPad: the app now stays full-screen and fits the screen properly — the gauge and graphs no longer stretch out of shape, and the bottom menu no longer overlaps your readings. - Fixed the charge and discharge switches showing the wrong state on some batteries; they now reflect what you actually set. - You can now add your email when reporting a problem, so we can reply by email as well as in the app.

This update fixes an important iPhone connection bug: some batteries kept asking for their Bluetooth PIN and rejected the correct one. Affected batteries now unlock and reconnect automatically — nothing to re-add or reset. Also new: steadier connections at the edge of Bluetooth range — the app adapts to signal strength and recovers more gently after a dropout, with a clear hint when weak signal is the cause — plus a Navy theme (Settings → Appearance) and better diagnostics behind Report a Problem so we can help you faster. 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.
