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.

3    Balance Discharge  Monitoring  and  Protection Adapter  (BDMP Adapter)
We provides 2 types of BDMP adapters for user to  choose.

Adapter#1                                                                                                           Adapter #2

4      Advantages
4.1  Military standard capacitor  of extreme low resistance  increases the ability of prevention of unwanted RF noise during flying.
4.2  Extreme low resistance  PCB is used  at  the power output section to get the best current endurance capability.
4.3  Microprocessor uses separate voltage regulator IC, with good anti-jamming capability
4.4 Compatible with Hobbywing's  Program Card
