==Overview==
* Important Note: The X750-A2 must be use with X750 18650 UPS HAT Shield, it is no use if you just purchase the X750-A2 board.
'''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 X700 on the wood material or carpet and unattended.
* Must keep the X700 away from children.
* Please watch Main Video and Tutorial Video regarding 18650 batteries at: https://www.staysafebattery.com/en/
