Interesting!
I actually reduced the value of the resistors (300mW) and it has been working very well. But this may be because I reduce the current from the charger as soon as one cell starts to balance. If your charger can't do that then it changes things. Still, have you tried the software options? - turn on balancing resisters at a lower voltage and then keep balancing once the charger has turned off (I can't remember if harlequin's code did that or not?).

I'll post my views on your other questions (prices, sourcing etc.) in another post. Good to hear from you!
