SAFETY INSTRUCTIONS AND WARNINGS

• The power adapter must with overvoltage and surge voltage protection; otherwise, it may easily damage the circuit board. Damage caused by a substandard power supply will not be covered under warranty.
• 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.
• Ensure your fingers do not touch the solder pads when inserting the battery into the battery holder, as this could cause a short circuit. This is extremely important!!!
• Make sure to insert the battery before turning on the UPS.
• Make sure to insert the battery before connecting the external charger to charge it.
• Please watch Main Video and Tutorial Video regarding 18650 batteries at: https://www.staysafebattery.com/en/

Overview

The X1208 UPS+M.2 NVMe 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.

FAQ

Q1: Can I use the official Raspberry Pi AI HAT together with the X1208 in the X1207-C1 case?

A: A: No. The X1208 uses the Raspberry Pi 5 PCIe connector, which is also required by the official Raspberry Pi AI HAT. Since the PCIe interface is already occupied by the X1208, the AI HAT cannot be installed simultaneously.
