Rattling battery?

[stitch]

Hey guys having a bit of an issue ,well kinda one of my echo batteries started rattling about 2 weeks back and now my second is doing the same , the performance doesn't seem to have degraded or anything just not lasting as long which I kinda expect to be normal
Ive tried giving it a search in google and can't find much except someone raising the idea it could lead to or be loose connections posing a fire risk , which made me think a little
Does anyone else have or had a similar experience lol , should I be concerned or stop being so critical it is a little odd when u lift it up to vape and it feels like a marble rolling up and down haha

I've noticed that with some of the 4.2V batteries myself Stitch.

If it's a concern, just send me an email and I'll take a look at them for you.
