==Safety Instructions & Warnings==
* <span class="tb_red">'''The charging current is set to 2.3-3.2A and charge cut-off voltage is 4.23V. Before connecting your battery to the UPS board, Please carefully confirm the maximum charging current and voltage, exceeding the upper limit of the charging specification that the battery can withstand will not only cause adverse reactions, but may also cause irreversible damage.'''</span>
* It is essential to read and understand these safety instructions and warnings before charging your batteries.
* <span class="tb_red">Lithium Polymer and Li-ion batteries are volatile. Failure to read and follow the instructions below may result in fire, personal injury, and damage to property if charged or used improperly.</span>
* Never make a wrong polarity connection when charging or discharging battery packs. <span class="tb_red">Always double-check the polarity of the battery's connector to ensure that "+" is connected to "+" and "-" is connected to "-".</span>
* <span class="tb_red">Do not mix and use old batteries with new batteries, or batteries with different brand names.</span>
* Lithium batteries have a limited cycle life. Please replace old batteries with new ones when they reach their service life or when they are two years old, whichever comes first.
* When charging the Battery Pack, please <span class="tb_red">place the battery in a fireproof container</span>. Do not leave the UPS shield on wood material or carpet unattended.
* Keep the UPS shield<span class="tb_red"> away from children</span> to ensure their safety.
* Please watch Main Video and Tutorial Video regarding 18650 batteries at: https://www.staysafebattery.com/en/

'''Reliable Power Backup''': The X1203 provides a stable 5.1V 5000mA power backup, ensuring uninterrupted operation of your Raspberry Pi. Whether you are running resource-intensive applications or powering multiple peripherals, the X1203 delivers reliable and consistent power supply.
'''Fast Charging''': With fast charging capabilities of up to 3000mA, the X1203 ensures quick recharging of the UPS, making it ready to provide backup power whenever needed.
'''Flexible charging''': You can use either type-c or DC5521 to charge the battery. When using type-c you can use the PD27W power supply that powers the Raspberry Pi 5, when you use the DC5521 you can use a variety of power adapters in the 6-18V range.
'''Versatile Design''': The X1203 is designed to be attached on bottom and don't use the 40-pin header, enabling easy stacking with other Raspberry Pi accessory boards. This versatility allows you to expand the functionality of your Raspberry Pi and create enhanced applications tailored to your specific needs.
