Package contents

ToolkitRC M6D charger comes with USB cable for firmware upgrades, Screen film protector and user manual.

Charger construction

This charger has two battery charging ports and two balancing lead ports for up to 6S. There is a temperature probe (DS1820) port in the middle, but there is no information on its use.

There is a fan on the side that turns on when the charger reaches the temperatures over 45℃.

On the back side of the charger you can find the input port (voltages between 7-28V or up to 6S battery) and the USB port for charging the phone or any other USB device with up to 2.1A.

Charger controls: scrolling the scroll wheel to the left or right for navigating through the menu and pushing the wheel for select or enter action. The CH button is for selecting the active battery charging channel (charging port). The selected channel will be highlighted in the screen. This button also allows to exit from the settings or selections menu.


Charger features overview

Battery checker

First of all ToolkitRC M6D charger can work as battery checker. Once you plug the battery into charging port it will power up and start showing the total voltage and the individual cell voltages. I don’t know if this is a useful feature, but it is definitely interesting and can not be found in any of my owned chargers (currently they are 6).

Internal battery resistance checker

Press and hold [CH/EXIT] button for two seconds to start testing the internal resistance of the active selected channel. After the test, the internal resistance will be displayed.


The short press on the scroll button opens the charging/discharging/storage mode settings. Select the “Charge” mode.

Select the battery type.

Select the battery cell number. I usually leave this setting to the “Auto” as the charger autodetects the cell count accurately and makes less mistakes than human.

You can select the desired end voltage from 4.05V to 4.25V for LiPo and from 4.20V to 4.40V for LiHV batteries. Be careful and don’t overcharge the LiPo batteries!

And the last setting is the charge current. Up to 15A in standard mode and up to 25A in synchronous mode. I usually charge LiPo batteries with 1C current and in 2C current when I need a quicker charge. 


For discharging the batteries you need to select the DisCHG mode.

If you have powered the charger by battery and charger power input source settings are set to “Battery” then you can select the Discharge mode to “Recycle“. “Recycle” mode “charges” up the supply battery with Discharge current. This allows to discharge batteries quicker with the higher current (up to 15A) then “Internal” mode (up to 3A).

Storage charge

For charging/discharging the batteries to the storage voltage you need to select the StoCHG mode. In this mode the charger will charge up or discharge to the storage voltage. The Storage charge mode settings are similar to the Discharge mode, just by default it is set to charge/discharge to 3.85V per cell. 

Firmware update

Connect the ToolkitRC M6D charger to PC with the supplied USB cable. Don’t connect the external power source to the charger. Charger will be powered through the USB cable. The computer will recognize the charger as USB disk named Toolkit.

Download the upgrade file app.upg (in the ZIP archieve) from the the official website  Extract the contents of the downloaded archive to the Toolkit disk. Overwrite the previous files in the USB disk if there are any.

Continuous charge

This is totally awesome feature. ToolkitRC M6D is able to automatically continue (or start) to charge (and discharge) the battery once you connect it. No need to press any key. When a battery is fully charged, unplug the battery, connect the next battery, the device will start to charge and discharge automatically. For this to work you need to set “Continuous work mode” to ON in the SETUP menu.

Synchronous mode

In sinchronous mode charger teams up the both battery charging ports to almost double the charging current output up to 25A. You need to set the Synchronous mode to “ON” in the setup

You need to get or make Y power adapter for sinchronous mode like the the one in the picture below.

Power supply

ToolkitRC M6D charger can be used as current limited power supply. If battery type is selected as “Power”, then you can select maximum current limit and voltage. Using this feature charger can power the hot wire cutting device or be as SmokeStopper device, limiting the maximum current.



ToolkitRC M6D is the best charger from the ToolkitRC at the time being. It has almost all the features that the user could want. Charging, discharging, storage feature, internal resistance checking, power supply with current limiter. It has two independent charging ports for charging/discharging two batteries simultaneously. They can be combined into one port for sinchronous charge with up to 25A. Charger displays the battery cell voltage with 3 decimal digits accuracy! 

ToolkitRC M6D has much better user interface than previous ToolkitRC chargers. It is more intuitive and easier to use. Navigation using the scroll wheel is easy and convenient. Much better than ToolkitRC M6 or M8 chargers.

One of the best features of this charger is continuous mode when you don’t need to press anything for starting the charging process. When the first battery finishes charging, just disconnect it and connect the next battery and the charging process starts automatically!

ToolkitRC supports their products by releasing the firmware updates with fixes and feature improvements. Firmware update frequency wise it is on par with the industry leader ISDT or maybe even better.

Bottom line: ToolkitRC M6D is feature rich, powerful, dual channel charger for the budget price. At the time being it is the cheapest dual battery charger/discharger in the market.
