I have two BC168's and both are playing up .
Sometime one channel or two give false cell readings.
SKYRC D100 I also have and works very well once you get used to the menu selection, it runs off ac or dc.
Using a power supply it charges using two separate channels at 100w output, direct ac channel A charges at 70w and B at 30w output.
BC168 are good and you can set voltage and amp load for charge, balance ,discharge etc ,etc
SKYRC is fairly variable and only allows charging if it correctly reads the battery format, if you input wrong details it doesn't work.
Storage charge is automatic and set.
Like the BC168 at a press of a button it gives individual cell voltages and I think resistance which I haven't yet used.
On both you can set time limit, both have internal fans.
