# Smart Batteries

Smart Batteries provide more accurate (and often more detailed) information about the state of a battery than an autopilot can estimate for "dumb" batteries. This allows for more more reliable flight planning notification of failure conditions. The information may include some of: remaining charge, time-to-empty (estimated), cell voltages (rated max/min, current voltage, etc.), temperature, currents, fault information, battery vendor, chemistry, etc.

PX4 supports (at least) following smart batteries:
