RC discharger says you need to use 10awg charging cables when doing 40A, so I'd try to get something in that gauge. This one only does 30A in recycle mode, but probably not a bad idea anyway.

This charger looks cool, but I've been doing 40A with my iCharger, so kinda hard to justify going back to 30A. Glad they included a recycle function though!

It depends.... If the wire length is just a few inches you can easily use smaller wires.

So maybe getting the right charging leads DOES make a difference...

Only a small difference measured with a stopwatch, not in the actual performance.

Just wanted to come back to this thread to say my M8D charger has been awesome so far. The interface is much easier than the iCharger's. No issues running both channels simultaneously at 30-amp charge or 30-amp regenerative discharge. Only complaints are:
1. Screen resolution/refresh rate isn't that great - This can make precise settings via touchscreen cumbersome - you'll want to use the scroll wheel. Regular tasks, like selecting a charge profile or starting a charge is not issue via touchscreen.
2. Voice prompts are annoying.

UPDATE to below statement. This charger DOES in fact offer a DC out option up to 30 volts.
I was about to pull the trigger on an iCharger DX6 but ended up going to the M8D due it being half the price. The only feature from the DX6 that I'd like to have on the M8D is the power supply function. It would be great to be able to plug my 24-volt soldering iron into the charger output instead of using a boost converter off the 12-volt supply.
If you look around AliExpress, you can find M8D's for under $80 delivered to your door.

We have a group of five people that will be plugging in multiple chargers to a single 100Ah LiFePO4 battery. I believe between us, we'll have three M8D's, two X6's and maybe a 308 or 406 DUO. I tested the setup at home with my 406DUO and M8D. No issues doing a combined 140 amps charging nor regenerative discharging with all four charger channels fully loaded with 1s batteries (we race 1/12th scale). We have the luxury of our own static pit spots, so we can leave the 12 volt battery on-site, but even if I had to lug it, it's only about 25 LBS. I paid about $160 for it, which is getting down close to the least expensive 2-pack of 4s 10,000mAh LiPo's I saw on Amazon and the big battery is 5x the capacity. The big battery also has the advantage of having a built-in battery management system, so no need to worry about balancing cells. Just for reference, charging the four ~7,500mAh 1s packs from 3.2 volts to full charge consumed 4% of the available capacity of the 100Ah LiFePO4. Simple math says we can charge more than 40 1s batteries from dead to full charge on a single charge of the LiFePO4 battery. We'll keep the big battery topped off with a small Hota 200-watt AC-powered charger that can run simultaneously during any charge or discharge cycles.

You can use 14g up to 4ft. I have noticed that the RC world loves to go overkill on their wire sizing.

I love mine and the interface is so much simpler than the icharger. One of the reasons I went away from it. I had been using my Muchmore charger for the last couple of years. The talking feature hasn’t affected me yet so I will keep it on…..lol.

I've seen in a few reviews that the talking and chimes the charger makes are annoying, anyone know if there are options to control that?

Yes. High, medium and low volume optons, as well as "Off."

I've got all the sound settings to "Off" and it still has that annoyingly loud buzzer when the cycle is finished. But yes, every other sound can be shut off with the 3 sound control in the Settings.

I want to turn mine up even louder 😂😂😂😂

has anyone tried discharging with a resistor like with the X6 ??

There is no discharging with resistor bank function with this charger.

I just ordered this charger for $73 shipped + tax from aliexpress. Seems like a crazy deal at this price. Lets see how it compares to all my ichargers. This would 100% be an icharger killer if it could discharge on the second channel into a resistor bank but since it cant seems like ichargers will stay in business.

Thinking of purchasing this charger, has a lot of great features and seems that those who have it really like it. I wonder if you could use the RC Discharger system with this charger for the recycle discharge function? May not be possible, but just a thought.
