One of our favorite little devices from Antigravity, the Battery Tracker for 12V LiFePO4 batteries is a unique product, offering monitoring and basic diagnostic information about a connected LFP starting or auxiliary battery via BT using the free Battery Tracker App. While this is not a replacement for a proper battery monitor by any means, this is a valuable, low-cost piece of kit for diagnostics and keeping a general eye on the state of your lithium start or auxiliary battery!

• Works on all 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.
