says it can charge at 70A when both channels are in parallel.

It would have been a holy-grail if you could get the channels in series.
But from a glance it looks like this guy is only able to charge 2X 10S, not 1X 20S.

So for packs 11s - 20s, you would need to separate before plugging in.

This charger would also require one hell of a PSU if you are going to push max charging power.
(wish they would start coming with a 120V AC input)

very nice
ive seen some meanwell 2kw PS - but not cheap
server power supplies might be more cost effective
also finding a circuit that can take 2kw without blowing can be challenging as well- but this definitely makes a nice toy for a quick charge
most household circuits do 1440watts safety and you trip the breaker at anything over 15amps so getting the full 2kw is tricky
unless you can put it on a good 20amp circuit

So I did a test drive of the new 4010duo. My server 24v 57A PSUS have been load tested by this unit up to 65A@23v loading them to about 1500w draw from the charger of their supposed 1400w capacity. They delivered 1400w actual charging power to the batteries. So the charger is roughly 93% efficient. Also by me fully loading the power supplies this should have applied a load of about 22-24A to a 15A house circuit and it did not trip during the 20 minutes of charging a 6s 10AH pack at 60A.

I just did several test to find the best combo and trying to max the full potential for my setup. I tested Sync and Async modes. Seems I can get max power if run both channels at 40A on 6s. Since I already charge in parallel it isn't going to hurt me to split this pack in half and charge two parallel groups. To max out my charger on this setup I used 3 of my Dell 12v 57A 700w power supplies. I ran two on one circuit and ran the 3rd on another circuit in my house. This gave me up to 2200w of power for my charger. The charger peaks slightly over 2000w delivered to the batteries with this setup.
