Thunder Power 65C lipo with very high resistence

I bought 8 Thunder Power 6s 7700 65C lipos about four months ago. I have finally finished the plane they are going in and am now charging them (kept at storage charge up until now). The packs will be used in series for 12s.

I noticed that one 6s pack has much higher resistence, 8 to 10 times higher, than the other packs. In addition to high resistence, my charger has a very hard time balancing this pack.

I have tried using different charging cables, different ports on my charger, two different chargers, I get the same result.

Has anyone encountered this problem before, and is there anything I can do other than return the pack to Thunder Power?

Thanks

Not uncommon to have variability. Far less common with quality packs (TP, Hyperion, etc.).

Absolutely nothing can be done to improve it other than returning to TP for warranty replacement.

I'm most concerned with the huge variance in resistence.

I have contacted Thunder Power about this issue. I was just wondering if anyone had encountered a similar issue and knew of a solution.

Only solution is to replace the pack, its a dud, happens to all of them.
