Someone might want to go down the road of "supply batteries" while stuff is being gathered:

I had originally thought that perhaps users might send me packs in the off season. I've bought a number of used lipos, but you never know what you're going to get so any comparisons are skewed. The shipping twice also runs the cost up to high.

A fair way might be to have the vendor/assembler send you a pack and if cycles or other tricks/tips make the performace better then so be it. Have them send the pack at whichever point they think is best knowing you may do a half dozen tests or so.

This gets rid of any discrepency for cycle life and cycle currents. I've found that a brand new pack always performs best and continues to degrade at every cycle. If they believe that 20 cycles is the best point then so be it, they send you one with 18 cycles on it.

Just trying to think ahead.
