Don do your last comments about uneven charge state of the cells still apply being that this pair of batteries will only be used as a pair running in parallel in my plane? I should have clarifed how I was going to be using these.
Since all cells in both packs will be getting identical use, then I would not expect any cell to be unevenly discharged.
If you charge them slowly, you won't need to worry about cell balance.
