About the app

BZ-Battery reads the high-voltage battery in a 2026 Toyota bZ4X and shows you what the car keeps to itself. You need an ELM327-compatible Bluetooth OBD adapter, plugged into the port under the dash. The cheap ones work. The adapter is not included. What you get: • Charge, power and current, live • All 104 cell voltages, with the weakest one marked • All 20 pack temperature sensors • Battery health, as the car itself reports it • Measured pack capacity, tracked over months • Every drive and charge kept, with the energy it used • Five dashboards. Pick the one you like. It only reads. The app cannot change a setting, clear a fault, or write anything to the car at all. That is enforced in the app, not left to good intentions. Nothing leaves your phone. No account, no cloud, no tracking. Your readings, history and settings stay on the device. Before you buy: this is built for the 2026 b
