mixing saddle lipos

[Bagman]

Hi all,

I've buggered up one of my saddle packs (4900 40c lrp). The surviving one is almost new and I'd like to keep it as a reserve. My question is if I buy another pair could I use my existing one if needed. For example I'm after buying a pair of 4400 40c lipos to use and I'm guessing I could use my existing one if I balance charge each time. Would it be a problem if it was 30c or 50c?
