    PRODUCT OVERVIEW 
     
 

The X720 is a multifunctional expansion board for all current models of the Raspberry Pi using a 40 pin header. It provides intelligent and safe power management, remote power on/wake on lan, safe shutdown and full poweroff through software, an advanced uninterruptible power supply, second 10/100M fast Ethernet, and a real- time clock. The X720 reserves the 40-pin header that can be stacked with other Raspberry Pi accessory boards for enhanced applications. The X720 can also be used with the X820 (2.5" HDD/SSD Shield) and X850 (MSATA SSD shield) for safe data backup.

  
     
  SAFETY INSTRUCTIONS AND WARNINGS
     
 
· You must read these safety instructions and warnings before charging your batteries. 
· Lithium Polymer and Li-ion batteries are volatile. Failure to read and follow the below instructions may result in fire, personal injury and damage to property if charged or used improperly. 
· Never make wrong polarity connection when charging and discharging battery packs. Always double check polarity of battery's connector to make sure "+" to "+" and "-" to "-". 
· Do not mix and use old batteries and new batteries, or batteries with different brand names. 
· Lithium batteries has it's cycle life, please replace old battery with new one when it reaches it's service life or when it is two year old, whichever comes first. 
· When charging Battery Pack, please put battery in a fire proof container. Please don't leave the X720 on the wood material or carpet and unattended. 
· Must keep the X720 away from children.
