Review: ToolkitRC M6D Dual-Port LiPo Battery Charger

by Oscar

Don’t like parallel charging? Then you should consider getting a multi-channel charger. The ToolkitRC M6D is a 2-port LiPo charger that allows you to charge 2 completely different batteries at the same time.

The M6D has a little brother, the ToolKitRC M6 – it’s single output, but in the smallest form factor possible.

Closer Look at the M6D Charger

The M6D is a great little portable charger for field charging. It has 2 output ports, which means you can charge two batteries of different types and specs simultaneously. This is something you cannot do with parallel charging.

ToolkitRC M6D Dual-Port LiPo Battery Charger

It doesn’t have built-in power supply, only takes a DC voltage input, so you can power it directly from a big LiPo battery. But you also have to get your own PSU. This is what I use: (see my review what I like and don’t like about it)

If you have any fully charged LiPo you are not going to fly on the day, you can put them back to storage by charging them back to the big battery. It’s faster and saves energy.

It has a USB port for charging all of your 5V devices, such as your GoPro, iPhone etc while you are at the field.

One of the most desired feature of today’s smart LiPo charger is the ability of checking internal resistance of the battery, which is also available in the ToolkitRC M6D.

The color LCD screen is very bright and visible even under the sun. However it’s not a touch screen, operation is done via the roller button. The quality of the button is really good, very user friendly, probably the best design so far from ToolKitRC.

You can combine both channels into one to double the output power, which I find to be a very interesting and useful feature for charging big 4S and 6S LiPo.


The main selling point of the M6D charger is probably the dual channels. Great charger if you are not a fan of parallel charging and still want to charge multiple batteries simultaneously to speed things up in the field, as well as on the bench. The interface seems to be a lot nicer than the previous M6 as well and that’s a big improvement.

Se não for as instruções de Óscar Liang, o meu T16, morre virgem!

I only got into FPV a few months ago. You’re quickly becoming my go to page for FPV help! (Even before Bardwel, sometimes I can read but can’t watch a video). 1) how can I support you and this blog? 2) I’m thinking if trying to get my kit as travel ready as possible. I fly internationally a lot and want to start bringing it with me. How big is this one? How heavy? Does it take 120 & 240v?

Oscar 7th September 2022 - 4:19 pm

1) Many thanks! You can support me here :)
2) Size: 98mm*68mm*35mm, Weight: 220g. It doesn’t take AC, you will need an external Power supply for this, so I don’t recommend it as your travel charger. This might be a better option, it takes both 120 and 240V:

Shitty charger, google “m6d balance port voltage match error”

Swede 25th December 2021 - 2:40 pm

That is the charger needing

Can you charge a car battery with this one?

roland 8th May 2021 - 10:45 pm

Hi@all, just a weired idea, the M6D hast also a “power mode” where it behaves like a bench powersupply with 1-30V output, would it be possible to connect both outputs in series to get up to 60V ?
if yes, that would be awesome and I could charge even my 14S E-Bike :D

Jiri 4th March 2021 - 10:12 am

Thats exactly my case. Now it is working correctly.
Thank you again.

Now I tried to charge 3s lipo battery with input voltage 12V and the input voltage number in left uper corner was red. When I tried to start charge there was a message: “input voltage is too low” and charging didnt start.
Am I doing something wrong? Do I need change the settings?

Oscar 4th March 2021 - 12:34 am

In system settings (hold down roller button), you probably have minimum voltage set higher than 12V? set it lower like 11.5V if you are using a 12V PSU. If you are using another 3S LiPo, set it to something like 10.5V.

Patrick 28th March 2024 - 8:01 am

Hi, can you provide a picture of these settings so I can find them too? Thanks.

Jiri 27th February 2021 - 7:50 am

I wish to charge two 6s batteries with this charger, what is the lowest voltage for input? (Is 24v enough or do I need 28v?)

Thank you for answer.

Oscar 1st March 2021 - 11:36 am

yea lower input voltage than output voltage is fine, it can step up.
