'''1. Enabled I2C Customers often ask if we support on automatic and safe shutdown at low battery capacity?

A prompt will appear asking Would shutdown command when it is low or low voltage, of course This low battery or low voltage value is an empirical value, and you like can specify it yourself in the ARM I2C interface to be enabled?, select "Yes" '''2.

==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 "-".
