When connecting packs in parallel the higher voltage packs will discharge into the lower voltage packs until the voltage is equal. Most people connect packs that are about the same state of charge and the same capapcity. Tests have been done with packs of widely different state of charge and even with batteries of different capacity without problems. Cellpro sells safety connectors which limit the current between packs, but most people are not using them. The balance connectors will also bleed the high voltage cells into the lower voltage cells. For instance all of the cell# 1's could end up at 3.75v, all the cell# 2's could end up at 3.73v, etc., until the charging begins.

RCGROUPS.com has a lot of info on parallel charging. The pattern community seems to be slow in adapting to parallel charging.
