LRP Lipo Stick rattles

[The Pookster]

When I shake my LRP lipo stick it rattles, and you can see the cells moving up and down inside, only by a small amount.

Is this normal, should I be worried?

The stick is a 5300 28c but only a few months old.

i have the same batterys and can tell you that they do the same when they are new you should only start to worry if the become bigger inside the case as when they balloon they are on the way out ....
