So... you want a 2kW RC Charger? ( iCharger 4010DUO )

[Doctorbass]

You're still tripping your breaker at 2800W, so.... :lol:

This charger can use separate power supplies for each channel. Just power each from separate 110v/15amp circuits. 8)

Might be a problem even if the psu you use have non isolated output!.. and even more dangerous if each 110V 15A circuit are L1 to neutral and L2 to neutral !... 110Vac short.. ouch!

This question came up a while back. What voltage to use? 18S seems to be a fairly good upgrade from 12S because you can easily make three strings of 6S for ease of balancing each string. For 20S, one option is four strings of 5S bricks...which seems overly complex for a small bump in voltage.

If someone used affordable 6S chargers for each string, 18S provides three strings of bricks that are all the same size (common and affordable 6S / 5000-mAh).

I suppose for 20S the benefit might be the ability to use two 10S chargers? (instead of three 6S chargers for 18S?).

Also, in the same line of questioning, can I have one power supply to feed three 6S chargers, or one power supply to feed two 10S chargers? If yes....what are the most common selections that seem to have a reasonable level of user-happiness?... (Hyperion, iCharger, etc)

Yeah soon, i'm rally busy with many project going on these weeks. I decided to do once at a time. :wink:

I have used this charger (iCharger 4010duo) now for over two months.
I mainly use it to cycle large (90-160ah) single LifePo4 cells or large (100ah)Nicad 5s Blocks for electric Cars

I used it to measure capacity of the NiCads so having two channels is a real plus as far as the amount of time it takes to test a bunch of cells.

I Like it a lot have not tried the 70A sync mode yet, but I have been pushing 20A and 30A for hours both charging and discharging.
Nice logging funcionality on microSd. But I hate the fact that I have to connect the charger to the computer and transfer each file into Logview to be able to get them in there. It would be nice with some converter of the files directly to logview format.

I guess it would be possible to bulk charge a 24s LifePo pack If I split it in two parts.

Any more reviews available today? I am a proud owner of iCharger 208B for many years and a very sad owner of Fatbuy8 (does not have any kind of logging of software).
This 4010 charger kinda meets my needs today. Not perfectly, but its close.

Few questions:
1. Are the two channels fully isolated? For example can I connect it to 3kW 48V power supply and then freely connect outputs in series or in parallel?
2. Can it do regenerative discharge? I mean if I connect it to battery instead of power supply.
3. Can it do cycling with regenerative discharge? For example I would be interested in 1000 cycles...
4. Can it store like 1000 cycles and 3 months of operation on the card? Is there some kind of limit?

Reading manual now, so far so awesome.

Few questions:
1. Are the two channels fully isolated? For example can I connect it to 3kW 48V power supply and then freely connect outputs in series or in parallel? NO these can be set in SYNC mode wich is a parallel mode (a kind of 10s2p....)
2. Can it do regenerative discharge? I mean if I connect it to battery instead of power supply. YES !
3. Can it do cycling with regenerative discharge? For example I would be interested in 1000 cycles... Not TESTED YET
4. Can it store like 1000 cycles and 3 months of operation on the card? Is there some kind of limit? I never tried the max limit but that info should be in the manual as well

Reading manual now, so far so awesome.

I can say i like alot that charger!! i also often use the sync mode to charge at 70A some high capacity cells or pack. It is a real charm to operate with that color slc screen and tthe intuitive menu!. it can also be recalibrated by user for al value. It give the Ri with pretty great acuracy too!

I power it with two RSP 1000 power supply in parallel when needed and it work well with up to 50V input.

I recommand it !!
