Yes, the 106B+ will provide data to a PC in real time via a USB cable. You can charge or discharge cells without being linked to a PC, but the data won't be saved.
The 206B and 208B both have some onboard memory, allowing them to save charge and discharge data when not attached to a PC.
2nd piece of KK 26650 i got 4533mAh, 1A, discharged to 2.60V set on IMAX B6 (UT-58E measured 2.826V, and i tested this 4X by charging a bit and discharging again to test the exact termination voltage, taking good care of contact resistance).
Get the MKNE then. That is Li Mn. KK can get from cnqualitygoods.com (slightly cheaper overall due to cheaper shipping and 40 cents less for the cell) and int-outdoor.com, MKNE only from int-outdoor but then you need to pay shipping.
The 4000's did well with the 30 amp discharge and any thing from 0.8 amp to 20 amp is nice and closely grouped. They would do well in RC but might not be cost effective
Does anyone know the exact chemistry of these KingKong cells? I know as mentioned above, they aren't IMR's but what are they then that it can handle such high current draw?
