A read-only Bluetooth monitor for lithium batteries using JK, JBD, Daly, or Humsienk battery-management systems.

Landing page captured for the 2026-11-11 issue.

For: Owners of JK, JBD, Daly, or Humsienk battery systems
Worth noticing: Its reconnect logic addresses Android Bluetooth error 133, while a connection-health panel reports drops, recoveries, and corrupted frames.

Field notes

BatMon describes a reconnect workflow that retries with increasing pauses, searches again after Android Bluetooth errors, and reports drops, recoveries, and corrupted frames. The page also specifies two-reading alert confirmation and phone-local history; location tracking is off by default, and the site says positions stay on the phone. Longer history, CSV export, and some remote features are listed in paid tiers.
