Power | Battery
The epConnected Asset device is designed to operate while powered from a battery connected to JST
connector J3. The battery must be a secondary, 1SxP lithium battery. A 3.7V nominal lithium-ion or lithium-
polymer battery is the suggested battery choice for the epConnected Asset. The battery should be chosen
with the consideration that the minimum required voltage is 3.2V and the charge termination voltage is
4.2V. The capacity of the battery may vary based on the needs of the end application. The battery charger
has a charge current limit of 500mA which should be taken into consideration when the capacity and
maximum allowable charge current of the battery are determined. Reverse polarity protection for battery
connection is provided by N-MOS component Q3. If a battery is not available, the operator may apply a DC
voltage (such as from a bench power supply) within the battery operating voltage range specification
(nominally 3.7V).
