The Antigravity BTR-3 Tracker +PLUS is a slim Bluetooth battery monitor that attaches to the battery terminals and reports condition to a free phone app. For a bike that sits between rides, it answers the question that matters before you gear up: is the battery ready to start.

One Tracker covers the whole garage: it monitors any 6V, 12V, or 24V battery, lithium or lead/acid, on motorcycles, cars, trucks, RVs, and boats. The +PLUS version adds a GPS location finder and up to 72 days of voltage logs, so a slow drain shows up as a trend line instead of a surprise.
