I have struggled getting the discharge current up to the stated max currents of the various iChargers with my resistor banks. With resistor banks of higher value, less load, I can discharge on my 308 Duo at 30A. The 308 Duo can use a 1Ω bank (5, 5Ω resistors in parallel) or a 200mΩ bank (5, 1Ω resistors in parallel). But, if I put my bank, 83mΩ (6, 500mΩ resistors in parallel) I can't get the max discharge current. The charger stops at about 65W on the load side even though it is in regen mode with the voltage and current settings maxed out. So that is the 308 Duo and the DX6, they behave the same.

Now the 456 Duo is even more of a mystery, With the 1Ω bank, I can get up to 38A, roughly 250W for the discharge. With the 200mΩ bank I can get about 25A, 160W, and with the 83mΩ bank I can only get to 11A or so, 65W. My best guess is that the iChargers are limiting the voltage based on the load size, and higher loads (lower IR banks) it limits the voltage output for safety reasons. Mind you, this is all with 2s batteries, I haven't tried this on a config higher than 2s.

So the question I have, has anyone got the new 456 or 458 Duo's to actually discharge 2s batteries at 45A? If so, what is the resistance of the resistor bank you are using?
Also, I have changed the max current and max voltage settings to other values and not max settings, but still can't get it to work. I am hoping that there is some setting that I have missed, I've read the manual and the manual gives no indication of actual load size to use for the regenerative discharge. Or at least none that I could find.
