I've found out that swelling is normally caused when the battery has been recharged when it's still warm/hot. This was the case with my Orion that swelled.
Have either of you charged a warm pack?

Exactly the same problem with my lrp shorties.I have four that have swelled.Only had them since the start of the regionals about three months now.Each one has only been charged a maximum of twenty times,each one balanced charged and storage charged in between race meetings.Only got them because we cannot run with the nano tech's at our regional series.But have had no problems with the nano tech's in the three years i have been using them,and they still have got loads of punch.

+1 for the nano techs, and the money you pay for them it do's not mater if they go south
£22 as against (I don't know) £60 to £80 for a branded lipo.

had an orion shorty that after a few months would not balance, one cell would only go to 3.93v.

i have had LRP 4500 shorty packs since november last year and they have no swelling and are spot on.

after a meeting i take them down to 7.4 storage charge without fail and don't charge them til race day

I've been running my LRP 4500 shorties getting on for a year without any issues, touch wood no sign of swelling. They've been run down to the cut off a couple of times too, so I wouldn't say they've had a really easy life.

Have you ever left them fully charged Andy?

Everyone thinks they should balance charge all the time - that is what causes the problems.
Balance when new and then just charge normally - balance again after 8-10 uses.
You won't get these issues.
6 years with Orion not a problem - now with LRP - no problem

Just trying to help you guys

What's the theory behind this?

What C rating are you lot charging at? I've never charged more than 1C and never had a pack swell.

I just check the voltage of each cell beforehand. If they are the same, I dont balance charge. If there is a difference, I do.

If it happens on 1S packs, then the theory is flawed.
