The Antigravity Battery Tracker for 12V LiFePO4 batteries is a one-of-a-kind product that provides monitoring and basic diagnostic information about a connected LFP starting or auxiliary battery via Bluetooth using the free Battery Tracker App. While it is not a replacement for a proper battery monitor, it is a useful, low-cost piece of equipment for diagnostics and keeping a general eye on the state of your lithium start or auxiliary battery!

• Works on all common-nominal-voltage 12V LiFePO4 batteries.
• Easily monitor your battery status through your phone using the Battery Tracker App.
• Monitor voltage, starting performance (if installed on an LFP starting battery), and the charging system.
• Immediate real-time data and history up to 31 days.
• Sends alerts to your phone when within BT range.
• Only draws 1mA, no significant drain on battery.
• Installs in less than two minutes.

Please note that while this device can be invaluable by alerting you to problems in your system before larger problems develop, the tests and information provided by the Battery Tracker and associated app should never be used in place of a professional mechanic's opinion.
