Hobbywing Guard-30A Brushless ESC for Aircraft and Helicopter

Hobbywing Guard-30A Brushless ESC for Aircraft and Helicopter
Description:
- Guard-30A is the product in the "Guard" series. 
- It has a special feature that makes it very interesting and attractive.
- Lithium Battery Balance Discharge Monitoring and Protection Design
- This function is a great innovation. With this function, the "Guard" series ESC can monitor the discharge voltage of  EACH Li-xx (Li-ion/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 R/C fans to reduce the cost for buying battery packs.
