I had IB3800's and they have got a HUGE imbalance in the pack (they where expensive cells from BK, something like 10-11 dollars each) three out of 16 cells have got this imbalance.

You will love those Hopf cells, they are the bomb.

When i freshly soldered my packs, at the first charge at .7A, they have got the exact same voltage (0.01V accurate)

With a discharge, the cells stayed at the same level too.

So those guys know what they are doing. After 4-5 charges the cells truely show their energy. You will love them, that's for sure.

I soldered them with solver tin and a 80W weller soldering iron with a huge tip (big thermal buffer) that way the cells stay cool. after 2 seconds of soldering, the temp was 36 degrees C.
