BS Battery BT 03 Battery Indicator

Stop guessing your battery’s health—especially when it’s tucked away in a hard-to-reach battery tray. Designed for both garage professionals and daily riders, the BS Battery BT 03 combines quick LED diagnostics with a permanent charger lead into one ultra-slim, convenient accessory.

Equipped with M8 eyelet terminals, the BT 03 bolts directly to your battery post, leaving an accessible SAE connection port exposed. The integrated 3-LED display gives you immediate, color-coded visual feedback on your 12V lead-acid battery’s state of charge (Green = Good, Orange = Fair, Red = Charge Now). When it’s time to top off, simply plug any compatible BS Smart Charger straight into the SAE port—no clamps, no seat removal, and no hassle.
