Found it! And according to this review the answer is "no."
Review of / Measurement on Xtar WP6 II charger
"The charger has a CC/CV like charge profile, the termination is not according to manufacturer recommendations, but works fine in practice. The support for long 18650 and included spacers makes this charger fine for 18650, 18500, 16340 and 14500 cells. With 6 channels it is possible to get a lot of cells charged in a reasonable time (Two 600 mA channels is faster than one 1200 mA channel when charging two cells). No charging at low voltages might give problems activating a tripped protection."
Further up in the review it lists the charge output voltages profile.
It's also 3 dual channels. Has a different twist on how it handles 2 batteries per channel, with separate monitoring of each battery. Still, it shouldn't be thought of as six completely independent channels, each with it's own power supply. (It swaps supplying voltage to each battery in a dual channel back and forth as it charges.) It's not a bad charger, just not the features I want.
Both these points are deal breakers for me. Will be ordering the Xtar WP2 II instead. From SuperT - of course!
