X1208

Overview

The X1208 UPS+POE Shield is engineered to provide the Raspberry Pi 5 with both a reliable power source and enhanced storage. It features an integrated M.2 NVMe SSD slot, ensuring robust data backup even during a power loss. This powerful combination safeguards valuable data, boosts system reliability, and guarantees continuous operation.

The X1208 delivers a stable 5.1 V/5 A backup power supply, enabling uninterrupted performance for demanding setups—from intensive applications to multiple peripherals. Its advanced power-management system intelligently monitors the Pi's status, automatically cutting power after shutdown to optimize battery life with ultra-low standby consumption. The board ensures seamless power switching during outages or adapter failures and supports convenient features such as auto power-on and AC power-loss detection.

SAFETY INSTRUCTIONS AND WARNINGS

• The default charging current is set to 1.5A 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.
• It is essential to read and understand these safety instructions and warnings before charging your batteries.
• 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.
• Never make a wrong polarity connection when charging or discharging battery packs. Always double-check the polarity of the battery's connector to ensure that "+" is connected to "+" and "-" is connected to "-".
• Do not mix and use old batteries with new batteries, or batteries with different brand names.
• 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 place the battery in a fireproof container. Do not leave the UPS shield on wood material or carpet unattended.
• Keep the UPS shield away from children to ensure their safety.
