'''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.

Customers often ask if we support automatic and safe shutdown at low battery capacity? Our suggestion is: You can refer to the A file and the B file to program this idea yourself: The idea is to read the current voltage or battery capacity cyclically, and then judge the program to execute the automatic shutdown command when it is low or low voltage, of course This low battery or low voltage value is an empirical value, and you can specify it yourself in the program.
