Understanding Powering Hacker Opto Pro Brushless Speed Controlls ESC

Hacker Opto Pro ESCs Require Their Own Battery

The Opto Pro series of brushless speed controllers by Hacker Brushless are a little different because they not have a Battery Eliminator Circuit (BEC) built in. The two Hacker Opto Pro ESCs we sell are the Hacker X-40 Opto Pro and the Hacker X-70 Opto Pro. This means the Hacker Opto Pro ESCs will only provide power to the brushless motor and will also not provide power to your radio receiver and servos. To power your receiver and servos you will need a dedicated receiver & servo battery pack. We recommend a Thunder Power Receiver Pack LiPoly Battery coupled with a 5.1V Voltage Regulator. When you do not have a second battery for the receiver the Hacker Opto Pro speed control will not function, will not beep and you will not notice any lights.

Properly Connecting a Hacker Opto Pro ESC

To properly install and connect a Hacker Opto Pro brushless speed control first connect it to the brushless motor and then connect it to the main flight battery. We recommend Thunder Power LiPoly batteries. The receiver lead coming from the Hacker Opto Pro ESC will connect to the throttle channel on the receiver. The servos will also connect to the receiver as usual. To power the receiver and servos connect a receiver pack battery to either the battery terminal or any open terminal on your radio receiver (RX). Once the entire system is connected properly with one battery for the receiver & servos and the other battery for the ESC and brushless motor the Hacker Opto Pro speed control will function normally.
