Yes Adam, the simplest ideas are the best. I have been baulking at fitting the spacers to the pack instead of the model as I have a hard carry case that I can fit 4 packs in if the 5S,s are side by side but not with the spacers fitted. But I guess the spacers could be velcroed in too.

Incidentally the ProPeak/1010C charged a 10S at 5A last night no problem but the pair are blinking noisy indoors.
