Battery Strap,
If you find the battery strap on the loose side, try fitting a thin piece of foam material between the cells and the strap. I need to do this when running 1700Mah cells in stock.
My Sanyo 2400Mah are a nice snug fit so don't need the foam.
One of the best features of the Specail is that battery brace. I thought it looked cheesey at first but it grows on you. Plus it makes an exelent heat sink.
