Gens Ace lipo swelling after sitting?

I would use a little higher cutoff like 3.4v if you have a c-link.

Check each cells voltage in that pack for abnormalities.

Did the puff reduce after charging?

I've already increased the cut-off to 3.3v vs the stock 3.2v.

I did read that charging a pack can reduce the swelling sometimes. Its currently balance charging at .5C right now. And that sometimes it can take several cycles.

I don't have a volt-meter right now. I suppose I should get one of those nifty little testers that report back on each cell so I don't have to probe each one.

However, I first charged the non-swollen pack, and after balance charging it at 1C its swollen NOW. It wasn't when I started charging it. So I'm thinking I may have to junk both packs unless I want to risk running them and having my truck go up in flames. I've heard that some people continue to run a slightly swollen pack without issue. I'm not sure if I want to take that risk.

I will see what the vendor will do for me. I ran the 3S lipo's in parallel with the same voltage cut-off setting as the 2S and those are fine. But the twin 2S packs are exhibiting problems.
