The CDC consistently puts move capacity into the batteries. When the Imax finishes charging the pack I sometimes top it up with the CDC, and it will usually put in another 200 mAh, without being over voltage. The CDC also charges the batteries quicker, the current stays higher for longer, again even with the chargers programmed the same way. The performance difference can be exaggerated too if the pack is older and no longer performing at its peak. I've also had the Imax false peak without me noticing.
If I take 200 mAh out of a pack just charged with the CDC then there is no difference in how the batteries perform on track.
I recently moved from two chargers running the generic B6 charge program (an imax and a skyrc) to a junsi icharger 308duo and the latter's charging program is a fair bit different in terms of the switchover from CC to CV mode. The icharger holds CC a lot longer and overall puts more Wh into all of my packs.
Also got an orion avantage one 406 which has a very different charge program again - and puts more in compared to the b6 programs.
The main reason I got the junsi was for the IR readouts. Handy to estimate cell wear. It also has a better balancing program (as in it's faster) than the B6 type and it's nice to charge my 7200 packs at 2S.
