Hehe, I take it there was a pinch or sarcasm with that? I couldnt see the cells in the 1st pic for the velrco & wires! Anyway, A123 cells are a fair bit longer & wider than Sub-C, so fitting them is a nightmare. An after market chassis would be best (the FLM is cheap and very cheerful), that way you could lay them out and strap them down with plenty room to spare, just wont be as neat as the proper chassis with the 'tub' for the batteries to sit inside....
Suicideneil I might be revealing my lack of experience and skill but that really IS clean compared to my emaxx with MM, BEC, Feigao, A123s: it's a big old mess really. The A123s are salvaged from deWalt packs and look like homemade bombs... But it is fun!!
