Hey paul, battery sort of charged I say sort of because 5 cells reached 4.20 but last cell kept dropping to 4.18 charger had cur back to 0.2a but after 2hrs timer cut off came on and stopped it.
What you reckon 1cell bit f@@ked?.

I would do a gentle hover with it and charge again. I've had this happen before and that fixed it. Worth a try.

Yep tried charging from 3.90v across battery, 1st 3cells seem to hit the 4.20 quickly but last 3cells seem to lag behind, don't know if that makes any difference or not?.

Ok will give it another go. And as for subtrims is there an easy way to mark where the links need to be adjusted to equal subtrims

Try a battery Doctor they can bring all your cells back inline again, I used to have a pack that did same battery doctor helped sort it out

4.18 to 4.20 isn't a biggie, i've just looked back and seen what charger your using, same as an imax 6, i've got one of these and the balancing is terrible quite often timing out before getting a pack in balance, i've ended up using an external balancer with mine and it reduces the charge time noticeably Now i've got the 450 a better charger is definitely on the the shopping list, icharger for me next i think, future proof...

Yup. My icharger usually balances to within 0.05v
