Hey Dan,

3-5C is what is recommended by Thunder Power, so that is what I've done, and I with some packs, I can see improved balance and improved voltage under load after a couple cycles. Nothing dramatic, but enough to make me think it is worth my time to break the packs in. If I don't break-in a pack, I've found that it does take a few flights before it seems to make full power - again nothing dramatic. I've never tried 1C for break-in, so I don't know if that helps or not...surely it won't hurt.

I don't think I'd use the first or second discharge cycle as a baseline...I suspect the packs improve for the first couple cycles.
