==Overview==
The '''X1209''' is a dedicated UPS expansion board for the Raspberry Pi, delivering reliable '''5.1V/6000mA backup''' power to ensure uninterrupted operation. It is designed to support demanding setups, including those running intensive applications or multiple peripherals.
'''UPS output:'''5.1V ±5% Max 6A
'''Battery charging current:''' 2.1A <span style="color:red">(IMPORTANT !!-- Please confirm before connecting your battery.)</span>
'''Terminal Battery Voltage:''' 4.23V <span style="color:red">(IMPORTANT !!-- Please confirm before connecting your battery.)</span>
'''Battery Recharge Threshold:''' 4.1V
'''Battery:''' 3.7V Lithium Battery <span style="color:red">(IMPORTANT !!-- Only parallel connection is supported, please check polarity of battery's connector to make sure "+" to "+" and "-" to "-". Connecting batteries in series will cause the X1209 to burn out!)</span>
'''Ports & Connectors:'''

==User Manual==
<div class="mw-collapsible-content">
A: The X1209 is compatible with 3.7V-rated batteries, such as 18650, 21700, 4680, and similar types, as long as they have a full charge voltage of 4.2V.
The default charging current is set to 2.1A and the 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.
