1. 01 Introduction Thank you for purchasing the EZRUN MAX8 V3 product HOBBYWING s high performance sensorless brushless motor electronic speed controller Brushless power systems can be very dangerous Any improper use may USER MANUAL EZRUN MAX8 Brushless Electronic Speed Controller EZRUN MAX8 V3 cause personal injury and damage to the product and related devices We strongly recommend reading through this user manual before use HOBBYWING has no control over the use installation or maintenance of this product No liability may be assumed for any damages or losses resulting from the use of the product HOBBYWING does not assume responsibility for any losses caused by unauthorized modifications to our product e Ensure all wires and connections are well insulated before connecting the ESC to related devices as short circuit will damage your ESC e Ensure all devices are well connected in order to prevent poor connections that may cause your vehicle to lose control or other unpredictable issues such as damage to the device e Read through the manuals of all power devices and chassis and ensure the power configuration is rational before using this unit Please use a soldering iron with the power of at least 60W to solder all input output wires and connectors e Do not hold the vehicle in the air and rev it up to full throttle as rubber tires can expand to extreme size or even crack to cause serious injury e Stop u2. The ESC didn t detect any throttle signal the GREEN LED flashed N times and then the RED LED flashed rapidly The vehicle ran backward when you pulled the throttle trigger towards you The motor suddenly stopped or significantly reduced the output in operation The motor stuttered but couldn t start The vehicle could run forward and brake but could not reverse The car ran forward backward slowly when the throttle trigger was at the neutral position 1 The LCD program box kept displaying CONNECTING ESC after you connected it to your ESC 2 The LED program card kept display 3 short lines after you connected it to your ESC When pressing the SET button to set the throttle neutral position the GREEN LED didn t flash and no beep was emitted or you were unable to set the full throttle endpoint and the full brake endpoint after the neutral position was accepted The neutral throttle value stored on your ESC is different from the value stored on the transmitter The ESC to motor wiring order was incorrect Your chassis is different from popular chassis The receiver was influenced by some foreign interference The ESC entered the battery LVC Low Voltage Cutoff protection The ESC entered the thermal over heat protection Some soldering between the motor and the ESC was not good The ESC was damaged some MOSFETs were burnt The throttle neutral position on your transmitt

7. e Cutoff Sets the voltage at which the ESC lowers or removes power to the motor in order to either keep the battery at a safe minimum voltage for Lipo batteries The ESC will monitor the battery voltage all the time it will immediately reduce the power to 50 and cut off the output 10 seconds later when the voltage goes below the cutoff threshold The RED LED will flash a short single flash that repeats x x vx to indicate the low voltage cutoff protection is activated If you use a NiMH pack then please set the Cutoff Voltage to Disabled Option 1 Disabled The ESC won t cut off the power due to low voltage after you select this option We do not recommend using this option when you use any LiPo pack 5S LiPo is an exception otherwise you will irreversibly damage it However for avoiding losing power in racing due to low voltage we recommend using this option this still may cause damage to your battery You need to select this option when you use a NiMH pack Option 2 Auto Low Low cutoff voltage not very easy to get the LVC Protection activated is applicable to batteries with poor discharge capability Option 3 Auto Intermediate Medium cutoff voltage prone to getting the LVC Protection activated is applicable to batteries with ordinary discharge capability Option 4 Auto High High cutoff voltage very prone to getting the LVC Protection activated is applicable to packs with great discharge capability Warning If you set
