<br />
== Technical overview ==<br />
* Output voltages: battery voltage (3S), 5 V up to 5 A, 3.3 V up to 300 mA<br />
* Control interface: I2C; enables real-time monitoring of battery voltage, current, and power<br />
* Supports 3 × 18650 lithium batteries in series (not included)<br />
* Charger: 12.6 V / 2 A via DC5521 female port<br />
* Dimensions: 60 mm × 93 mm; mounting hole diameter 3.0 mm<br />
* Multiple protection circuits: overcharge, over-discharge, overcurrent, short-circuit, reverse-polarity protection, and equalizing charge<br />
* Onboard 5 V regulator providing up to 5 A continuous output, suitable for Raspberry Pi and Jetson Nano<br />
* LED indicators for verifying correct battery connection<br />

'''Commands and examples – verify before use:''' <br />
<syntaxhighlight lang="text"><br />
sudo raspi-config<br />
cd UPS\ Module\ 3S/<br />
sudo python3 INA219.py<br />
</syntaxhighlight><br />
<br />
== Notes and version constraints ==<br />
* Batteries are not included; only use compatible 18650 cells<br />
* First-time connection: if the LED is on, the battery is reversed — do not charge it<br />
* If there is no power output on first connection, press the BOOT button to activate the battery protection chip<br />
* Use only the supplied 12.6 V / 2 A power supply for charging; other supplies may damage the product if their ripple is too large or unstable<br />
* If the positive insulation pad is broken, stop using the battery due to short-circuit/fire risk<br />
* Never pry the battery's positive terminal with a screwdriver; work from the negative terminal instead<br />
* Install the acrylic insulating board before use because exposed components on the underside can short against metal or conductors<br />
* Lithium batteries have limited cycle life; replace them when they reach max cycles or after two years of operation<br />
* Do not mix old and new batteries or different brands<br />
