MAD MAX12 250A HV 6-12S Brushless Sensored ESC for 1/5 RC Model Car, Bluetooth App, IP67, BEC 6/7.4/8.4V

Overview

MAD MAX12 250A HV 6-12S LiPo brushless sensored electronic speed controller (ESC) for 1/5 RC model car. It supports sensor or sensorless square wave control of brushless motors and built-in Bluetooth connection to a mobile app for parameter setting, data reading, and firmware upgrades. The provided product information also specifies 32-bit control.

Key Features

• 250A continuous current with wave-by-wave style current limiting to help control peak current
• 6-12S LiPo input (supports use with a DC power supply; operating parameters may need modulation if the power supply capacity is limited)
• Built-in Bluetooth: parameter adjustment, firmware upgrade, and motor operation data observation (data log + real-time data)
• Fan intelligent start/stop function: turns on at > 55C and turns off at < 50C; fan power is cut if abnormal large current occurs
• Built-in BEC with selectable voltage via mobile app (6.0V / 7.4V / 8.4V) and high current capability (8A continuous, 25A short-term)
• Turbo timing available (max support 26)
• Full protection: low voltage, over voltage, throttle loss, abnormal braking, over temperature, etc.
• Supports X.BUS protocol for real-time control and reading operation data via bus (automation/robot control supported per provided documentation)
• All-weather operation capability: IP67 protection rating (waterproof/dustproof)

Specifications

Features (Provided List)

• 2.1 Meticulously proved commutation scheme, smooth commutation even in noninductive.
• 2.2 Active freewheeling technology can reduce MOS heating while avoiding excessive current pulses.
• 2.3 Current limiting in each PWM cycle reduces the impact of pulse current on the motor.
• 2.4 Intelligent heat dissipation ensures the fan operates silently at low temperatures.
• 2.5 Built-in Bluetooth connections to mobile app for hardware management and parameters setting.
• 2.6 Mobile app data observation interface for viewing ESC recording data (static data) and real-time debugging data.
• 2.7 High-power DC conversion circuit makes BEC a potent loading capacity.
• 2.8 Full protection: low voltage, over voltage, throttle loss, abnormal braking, over temperature etc.
• 2.9 Turbo timing available.
• 2.10 No need to buy additional modules, you have a ready-to-run speed controller.
• 2.11 Supporting X.BUS protocol, real-time control of ESC and reading of operation data through bus. It can be used for robot control or other automated programming control.

Connections

• Switch wire: red and black
• Throttle wire: red = BEC+, black = BEC-, white = throttle
• X.BUS wire: red = BEC+, brown = BEC-, yellow = X.BUS
• Supports hall sensing wire connection for sensored motors

Start Process

1. Check whether the circuit is open, short circuit, or in poor contact.
2. Check whether the motor is stuck.
3. Plug in the power cable.
4. Turn on the power button. When you hear the battery prompt tone (described in the Normal startup section of LED/light & sound prompts), startup is normal. If the throttle is normal, throttle operation can be performed normally.

Set the Throttle Range

1. Keep the ESC off, move the throttle to the end point of reversal, then power up the ESC and wait for the red and green lights to stop flashing (about 5s).
2. Move the throttle to the end point of forward within 1s and hold it; wait for the green light to stop flashing.
3. Move the throttle to the neutral position within 1s and hold it; wait for the red light to stop flashing.
4. Success prompt repeats four times: red + green lights on + motor beep “so, mi, do” + red/green lights off + 0.2s vacancy. Failure prompt: no signs; ESC powers on.

Bluetooth

The Bluetooth naming rule is “approximate model” + “-” + “ESC code ID”. Example: “XC_E3-1C89”, where XC_E3 is the approximate model and “1C-89” is the hexadecimal code ID. Even if the Bluetooth name is set by the user, the ESC code ID is retained to avoid two devices having the same name.

Recover Factory Parameters

Restore Bluetooth to factory settings (including default password and name):

1. Connect the ESC wire (white wire) to BEC+ (red wire).
2. Turn on the ESC.
3. Disconnect from BEC when the green light is off and the red light is on.
4. Remove the short circuit.

When boot is activated, Bluetooth status restores to factory value (password restored to 1234, and the name restored to factory state). Then restart the ESC. If there is a hardware error, Boot can be activated in this way to upgrade hardware.

Restore parameters to factory settings: click the default button on the app parameter page.

Configurable Items (via App)

Running Mode Details

• Option 1: Forward with brake The vehicle can only move forward and has brake function (commonly acceptable in races).
• Option 2: Forward/Reverse and Brake “Training” mode: first reverse trigger applies brake; reversing requires returning to neutral and triggering reverse again after the motor stops, to help prevent accidental reverse.
• Option 3: Forward and Reverse Motor reverses when throttle is pushed from neutral to reverse point (generally used in special vehicles).

LED Status & Beep Instructions

Notes:
1) Red light matches long tone; green light matches short tone.
2) For saving power, all beeps last for 5 minutes; if all faults are recovered, it takes effect again in the next 5 minutes.
3) “…” in light cue represents repetition of the previous action.

Precautions

• Do not connect the ESC input wires DC+ and DC- in reverse; reverse connection may damage the ESC. If damaged in this case, relevant warranty service will not be provided.
• If a Hall sensor is used, check the motor phase wires and Hall wiring.
• For motors without temperature sensors, long-term high-power operation may cause burnout.
• Some motors cannot support high speed due to their mechanical structure; forcibly increasing speed may damage the motor.
• If not used for more than 1 hour, it is recommended to unplug the ESC power wires.
• If any modifications are made to the connection line, check the circuit carefully before use; open the throttle slowly and confirm there are no errors before normal operation.
