SB-UCM battery support is implemented with the Texas instruments BQ24161 power-path and battery charger.
The battery should be connected to the system through the '''P19''' Battery connector.
Any battery complying with the requirements described in BQ24161 documentation can be used.

<blockquote>
=== System Power ===
The system-on-module at main power source connector '''P1''' (referred to as '''VSYS''' in SoM documentation is determined by available power sources as shown in the table below.

{{note|When using a battery, the user must make sure that battery voltage is always within the recommended voltage range of UCM-iMX7 main power supply voltage '''VSYS''' .}}

=== Battery charging ===
SB-UCM is capable of charging the main battery whenever both the DC power source and Battery are present.
Battery charging process is autonomous and can be monitored by software through the BQ24161 I2C interface.
Please refer to SB-UCM schematics for additional details.<br>
LED '''DS1''' indicates battery charging is in progress.
