If you've opened up both the Spektrum and the HK packs and compared the electronic then that is great, but short of that I'm not prepared to assume exactly what they are both capable of.
The Spektrum pack is managing to achieve a balance capability somehow, I just don't know for sure that HK pack isn't trying to do the same.
Also we shouldn't get too excited about this as in such a low current application the effect of a small balance difference is going to be slight.
A more general concern for me would be letting the lipo fully charge at all, as fully charged for long periods of time is a very poor way to treat a lipo and with such a slow discharge rate it is going to linger at or close to the fully charged state a lot longer than is healthy.
