How to measure. Measure around pack divide by two ,that is the mininum size you need. Most shrink wrap will shrink approx. 50% so a little larger is fine.

Status: offline 		Hmmm. I posted here yesterday and now it's gone? Anyway, 56mm is too small. It's more like 3.5" to wrap two widthwise, and 4.5" for lengthwise.
I get my shrinkwqrap from www.batteryspace.com. look for DIY shrinkwrap...

Although you can use larger I have found that the smaller you use the better the ends look. I get mine from www.radicalrc.com. Great service also. I have about 5 different sizes I got for various size packs. You should look under "Batt Packs & Heat Shrink" then "Pack Parts & Heat Shrink" then scroll down to "Pack Heat Shrink." They also have all of the other pack making parts.

To measure your cells tape them together then wrap a piece of paper around them and mark where the paper touches. Tape the paper together at the mark then press the paper loop flat. Measure the flattened piece of paper and select the next size of shrink larger than the paper measurement.

Best, Dennis
