User Manual

Guard-40A is the product in the "Guard" series.  

It has a special design that makes it very interesting and attractive.

 Lithium Battery "Balance Discharge Monitoring and Protection" Design (BDMP)
This function is a great innovation. With this function, the "Guard" series ESC can monitor the discharge voltage of  EACH LiPo cell in a battery pack at any time. So from now you needn't worry about the over-discharge problem for the weakest cell, the lithium battery pack will have a much longer life. This design helps you to reduce the cost for buying battery packs.
