D750 MIX
AC/DC Multi-Function Smart Charger

Introduction

Congratulations on choosing the SkyRC D750 MIX AC/DC Multi-Function Smart Charger!
The D750 MIX features two independent channels and supports the vast majority of RC batteries on the market. It handles up to 8-cell LiPo batteries, delivering up to 32A per channel—or an impressive 55A when parallel charging. With dual input options  (AC/DC), the D750 MIX adapts easily to any setup. Beyond standard charging, it offers DC power output, parallel charging, and reverse discharge, making it a powerful and versatile all-in-one platform for RC enthusiasts.
Before first use, carefully read the manual, warnings, and safety instructions. Incorrect use of the charger or charging batteries improperly can be extremely hazardous, potentially leading to fires or even explosions.

Power and Battery Connection & Charging (Demo with 6-Cell LiPo)

1. Connect to the Power Source
SkyRC D750 MIX supports two types of power input: AC 100-240V and DC 9-49V

https://q.thingsserver.com/s/7880b4a683dde0d1

* AC Input: Long press the AC power button to turn on.
DC Input: It powers on automatically once the power supply is connected.

2. Connect the Battery
To avoid short circuit, connect charge leads to charger first, then battery.
Disconnect in reverse order.
1.LiPo Battery Connection with Balance Connector.

2. Select Channel A or B where the battery is connected.
3. Press the scroll wheel to configure the charging parameters:

• Battery type
• Number of cells
• Target voltage
• Charge current
• Cut-off temperature
• Press “Start” to begin charging.

For safety reasons, it is highly recommended to charge Lithium batteries (LiPo, Li-ion, LiFe and LiHV) using Balance CHG mode unless the battery comes without a balance connector.
The balance wire attached to the battery must be connected to the charger with the black wire aligned with the negative (-) marking.
Ensure correct polarity!

Long press to turn the DC power function on or off.

Notes:

1. Both output ports can work independently. Parallel operation only when using both outputs simultaneously.
   Series connection will destroy the unit.
2. No reverse polarity protection on output ports. Reverse connection will damage the unit.

Parallel Charging

SkyRC D750 MIX offers a Parallel Charging mode to deliver higher charging current.

https://q.thingsserver.com/s/917b36d0797ad9a7

Note: Parallel Charging is only supported for lithium batteries.
Other battery types are not supported!

Use the dedicated parallel charging cable* for this product to correctly connect the battery’s main lead and balance lead.

1. Select the channel to which the battery’s balance lead is connected, e.g., Channel A;
2. Choose the correct battery type (LiPo / LiFe / Li-ion / LiHV);
3. In the task menu, select the “Parallel Charge” program;
4. Set the charging current (adjustable range: 33–50A);
5. Once all settings are complete, press “Start” to begin parallel charging.

*The parallel charging cable is sold separately!

Reverse Discharge

With Reverse Discharge mode, SkyRC D750 MIX allows you to transfer energy from an idle battery to another battery, reducing energy waste.

https://q.thingsserver.com/s/145a2a8d4210d612

Example:
For instance, we use Channel B to discharge the source battery and Channel A to charge the target battery.

1. Select the correct battery type.
   Only following battery types are supported(the charge side has no restrictions):
   2–8S LiXX
   8–20S NiXX
   3S / 6S / 12S Pb
2. Select the number of cells (optional).
   If the balance lead is connected, the system can automatically detect the cell count. You may also set it manually. If no balance lead is connected, manual input is required.
3. From the task menu, select “Reverse Discharge.”
4. Configure Discharge parameters:
   Cut-off voltage
   Discharge current
   Cut-off temperature
5. Press “Continue at A” to Configure Charge parameters:
   Battery type
   Number of cells
   Target voltage
   Charge current
   Cut-off temperature
6. Press “Start” to begin reverse discharge.
   Notes:
   AC Input: no voltage limit; DC input: must be <40V to enable reverse discharge function.
   Cannot operate simultaneously with DC power input
   Cannot operate simultaneously with Type-C input
   Minimum discharge power requirement: >20W (system will not activate below this threshold)

External Discharge

D750 MIX supports external discharge, reaching up to 40A when connected to the BD350/BD380 discharger.

https://q.thingsserver.com/s/a7b66533a6848653

1. Once the power supply is connected, D750 MIX powers up and enters the main interface automatically;
2. Connect the BD350/BD380 discharger to D750 MIX;
3. Connect the battery to Port A on D750 MIX;
4. Select the battery type, number of cells, discharge program, cut-off voltage, and discharge current;
5. Start the program once the settings are configured.

Note:

• The BD350/BD380 discharger is not included and must be purchased separately.
• External discharge is available only on Port A.
